The Monetary System: Sovereign Debt Crises (2026)
Framework evergreen; the history is dated and final. Data as of August 2026. How a sovereign debt burden becomes unsustainable — and the ways out — is durable and reads that way here. The figures for the seven historical cases are settled outturns, each sourced and dated beneath its table. The three live cases — Japan (Section 10), the United States (11) and France (12) — are the deliberate exception — current figures and forward scenarios, not finished history, and none predicts a crisis. Any worked ratio illustrates the mechanism, not a forecast. Informational only, not investment advice; AI-assisted and human-reviewed (see Section 15).
The Monetary System series built up the machinery of government money — how a state spends and borrows (Part 1), how that debt is financed and priced in the bond market (Part 2), and how the central bank sets the rates and creates the money behind it all (Part 3). This companion shows that whole machinery failing: seven historical episodes where a government’s debt, or the currency carrying it, stopped being sustainable — what the numbers looked like at the breaking point, how each country got out, and what the exit cost — then three live balance sheets, Japan, the US and France, carrying dangerous-looking debt today. When you want the company- and project-level data that sits beneath the macro picture, that is what Metal Pilot is for.
The headline: there are only five ways out of an unpayable debt, and every crisis in history is some combination of them — inflate it away, restructure it, get rescued, reset the currency, or adjust and grow. Which mix a country reaches for is decided less by choice than by what its situation leaves on the table.
This is a companion to the whole of “The Monetary System”, not a fourth part of the series. The three parts teach the mechanics — Part 1 · Spending & Debt , Part 2 · Bonds & Yields and Part 3 · Interest Rates & Inflation ; this guide shows five times they broke.
TL;DR & Key Takeaways
- There are five exits, not one. A government that cannot pay can inflate the debt away, restructure it, get an external rescue, reset the currency, or adjust and grow out of it — every case below combines these five, and adjustment alone has never quite sufficed: even Britain’s textbook grow-out rode on a quiet inflation tax.
- The level of debt is rarely the trigger; the structure is. Who the debt is owed to, and in what currency, matters more than its size — which is why Germany’s far larger debt was an easier trap than Greece’s, Britain outgrew a war debt of ~250% of GDP without a default, and Japan carries the most of all with no crisis.
- Three balance sheets are the live warning (Sections 10–12). Japan carries ~207% of GDP and no crisis — it borrows in its own currency, from its own people, at near-zero rates now normalising. The US holds that same shield in reserve-currency form, yet its interest bill has passed defense. France holds the opposite card — a core economy with no printing press, ~116% of GDP and a hung parliament. All three are warnings, not forecasts.
- Inflation is the quietest default. The US in 1965–82 — and Britain after 1945 — never missed a payment, yet the dollar lost roughly two-thirds of its purchasing power and British gilt-holders earned years of negative real returns: the burden shifts from creditors to everyone holding the currency.
- A currency mismatch is the killer. Mexico (1982) and Argentina (2001) carried debt that looked manageable against GDP until a devaluation multiplied the cost of their dollar debt overnight — denomination, not size, broke both.
- But a printing press is not an absolute shield. Russia (1998) borrowed in its own currency and still chose to default on its ruble debt rather than hyper-inflate it away — owning the printing press lowers the odds of default without removing them.
- Someone always pays. Every exit except pure growth writes down someone’s claim on paper money — the thread running back through the whole series, and why the guide closes on real assets.
- The hedge is the currency breaking, not the crisis. Scored across the seven cases (Sections 2.6–8.6), gold and foreign currency held or gained into every break whose currency gave way, while cash and government bonds were wiped — then equities and the restructured bonds led the recovery. Greece is the exception that proves it: the euro held, so there cash was safe and the real assets fell.
- The state was often the one taking. In most cases the loss was imposed by decree, not just by the market — the US banned the gold that hedged best, Argentina seized dollar deposits, Greece rewrote the bond contract (Table 17) — so custody and jurisdiction, not asset class alone, decide whether a hedge survives.
New to the topic? Read straight through from Section 1 for the framework, then the cases in order. Here for a specific one? Jump to Germany (Section 2), the UK (3), the US (4), Mexico (5), Russia (6), Argentina (7) or Greece (8); the synthesis in Section 9 distils them into one framework, and the three live cases — Japan (10), the United States (11) and France (12) — apply it to the present. Every specialised term is defined in the Vocabulary (Section 14).
1. When does debt become unsustainable?
“Unsustainable” is not a debt level. There is no ratio above which a government must default and below which it is safe — Japan carries over 200% of GDP without a crisis (Section 10 is the live test of the framework), while Argentina has defaulted near 50%. Sustainability is about dynamics: whether the debt ratio is heading up or down on its own momentum, and whether the government can still fund itself at a price it can bear — the bond yield, and the credit risk inside it, that Part 2 anatomises. Part 1 set out the arithmetic; this guide reads seven cases through the same small set of gauges.
Table 1. The metric legend — the gauges every case is read against
| Metric | What it measures | The stress signal |
|---|---|---|
| Debt / GDP | The stock of debt against the size of the economy that services it (a level, not a flow) | Rising fast under its own momentum, regardless of the absolute level |
| Primary balance / GDP | This year’s spending minus revenue, excluding interest — the part policymakers control now | A persistent primary deficit means the debt grows before a cent of interest is added |
| r − g | The government’s borrowing cost (r) minus the economy’s nominal growth (g) | When r > g, the ratio climbs even at a balanced primary budget — debt compounds faster than the economy |
| Inflation (CPI) | How fast money is losing value | High inflation erodes the real value of fixed-rate debt — the quiet default — but destroys the bond market that funds the state |
| Interest / revenue | The share of the tax take pre-committed to creditors | Once interest crowds out spending, the politics of paying collapse before the arithmetic does |
| Currency mismatch | Foreign-currency debt set against the currency the economy actually earns | A devaluation multiplies the local-cost of FX debt overnight — the level looked fine until it didn’t |
Source: the metric set follows The Monetary System, Part 1 and the IMF’s fiscal-sustainability framework (IMF, Debt Sustainability Analysis ). Definitions are evergreen; they carry no dated figure.
The budget identity from Part 1 leaves a government with only so many moves when the debt stops adding up. It can inflate — let (or make) money lose value, cutting the real burden of fixed debt while taxing everyone who holds the currency. It can restructure — stop paying in full and force creditors to accept less. It can secure an external rescue — the IMF, an ally or a currency bloc bridging the gap. It can reset the currency — devalue or replace the money the debt is written in. Or it can adjust and grow — run a primary surplus and engineer nominal growth faster than its borrowing cost, so the ratio shrinks under it. Those are the five exits this guide tracks, and the cases show they are almost never used alone.
Each case names its “moment” — the point this guide dates the breaking point to, and the date the baseline table is anchored on. The moment is a judgement call, so every case says why that date: the day convertibility broke, the moratorium was called, the deficit was revealed. Read the cases in chronological order and a pattern emerges — not that the same thing keeps happening, but that the same five tools keep being combined in different proportions, dictated by what each country could and could not do.
Two cases are deliberately the odd ones out. The United States in 1965–82 and the United Kingdom after 1945 never defaulted — the US let its debt ratio fall through inflation, Britain outgrew its through growth and financial repression. They are here because they show the two exits that never appear on a list of defaults — inflating the burden away and outgrowing it — and because together they are the cleanest demonstration of Part 1’s central point: that a sovereign can shed real debt without ever missing a payment, simply by keeping the money it borrows in worth less, or the economy behind it worth more, than the debt. Keep them in mind as the controls against which the five true crises read.
2. Germany after WWII (1945–1953)
2.1 Context & baseline metrics
By 1945 Germany carried the most extreme debt overhang in this guide against the most broken economy. Financing two total wars had buried the Reich under obligations — war bonds, occupation costs, and the reparation and pre-war external claims that would outlast the regime that ran them up — while the productive base to service any of it lay in ruins, with output roughly a third below its pre-war level. The Reichsmark still circulated but had ceased to function as money: strict price controls held official prices down while the real economy ran on cigarettes and barter, a textbook repressed inflation where the monetary overhang was hidden by controls rather than shown in prices. There was no sovereign budget to speak of — the country was under Allied occupation.
Pre-1950 German national accounts are academic and institutional reconstructions, not measured series, so every figure here is an estimate and flagged as one; the point is the order of magnitude, which is not in doubt — which is also why Germany carries no debt/GDP chart, since a milestone line would imply a precision the reconstructions cannot support.
Table 2. Germany at the breaking point (1945–1948, estimated)
| Metric | At the breaking point | Note |
|---|---|---|
| Public debt / GDP | ~300–400% (estimate) | War financing against a collapsed denominator; scholarly reconstructions vary widely |
| Real output | ~⅓ below pre-war | Destroyed capital stock, occupied and divided |
| Inflation | Suppressed | Price controls + a large monetary overhang — a cigarette-and-barter economy, not open hyperinflation |
| Currency | Reichsmark, discredited | Replaced by the Deutsche Mark in June 1948 |
| External debt | ~30bn DM (later settlement basis) | Pre-war debts + post-war claims, unresolved until 1953 |
| Sovereign status | None (occupied) | No independent central bank or budget until the Federal Republic (1949) |
Source: estimates from Deutsche Bundesbank monetary-history material, the IMF on the 1948 reform, and economic-history work on the 1953 London Agreement. Pre-1950 magnitudes are reconstructions — treat as orders of magnitude, not measured values.
2.2 Stages: from strain to resolution
Germany’s exit ran through the two boldest moves in this guide — it did not pay its debt down so much as legally cancel most of it, twice over. First the domestic overhang was wiped by a currency reform: on 20 June 1948 the Deutsche Mark replaced the Reichsmark, with everyday flows (wages, rents) converted at 1:1 but accumulated savings converted at an effective rate of less than one new mark for ten old ones — roughly a 90%-plus write-down of monetary claims at a stroke. Then the external debt was cut by agreement: the 1953 London Debt Agreement cancelled about half of Germany’s foreign obligations — some 15 billion of about 30 billion DM — and, crucially, tied the remaining repayments to Germany running trade surpluses, so servicing the debt could never choke the recovery. On top of both sat Marshall Plan aid and, once Ludwig Erhard freed prices alongside the 1948 reform, an economy that took off: the Wirtschaftswunder delivered roughly 8% real growth a year through the 1950s.
Table 3. Germany — the crisis in stages
| Year | Event | What changed |
|---|---|---|
| 1945 | War ends | Reich debt overhang meets a collapsed, occupied economy; the Reichsmark is discredited |
| 1948 (Jun) | Currency reform | Deutsche Mark replaces Reichsmark; savings converted at under 1:10 — the monetary overhang is wiped |
| 1948 | Prices freed + Marshall Plan | Erhard’s decontrol restarts a real price economy; external aid supports it |
| 1953 (Feb) | London Debt Agreement | ~50% of external debt cancelled (~15 of ~30bn DM); repayment tied to trade surpluses |
| 1950s | Wirtschaftswunder | ~8%/yr real growth; by the late 1950s debt/GDP is low and Germany is a creditor nation |

2.3 Consequences — short and long term
The short-term cost fell on savers: anyone holding Reichsmark balances in 1948 saw them very nearly wiped, the second time in twenty-five years that German savings had been destroyed by monetary collapse — the 1923 hyperinflation was still in living memory. That double trauma is the long shadow. It hard-wired Germany’s monetary culture: an institutional horror of inflation that produced the fiercely independent, hard-money Bundesbank, and a national fiscal conservatism that still shapes European policy today. The upside shadow is equally long. Because the debt was cancelled rather than serviced into the ground, the recovery was never starved of capital: by the late 1950s Germany’s debt ratio was low and the country had become a creditor to the rest of the world — the textbook case for why writing debt down early can beat grinding it down slowly.
2.4 Final result
Germany used four of the five exits at once — a currency reset (1948), a restructure (the 1953 write-down), an external rescue (Marshall Plan and creditor concessions), and adjust-and-grow (decontrol plus the Wirtschaftswunder) — and skipped only open inflation, which the currency reform pre-empted. The debt did not shrink; it was mostly cancelled, and what remained was tied to the economy’s capacity to pay. The lesson that feeds the synthesis: the fastest way out of an overhang is not to pay it but to write it off before it strangles the recovery — available only to a debtor its creditors have a strategic reason to rebuild.
2.5 When the state rewrote the rules
Germany’s write-down was executed by law, not by the market — and twice. The 1948 currency reform that cut savings by roughly 90% was a decree; less remembered, the 1952 Equalization of Burdens Act (Lastenausgleich) then levied about half of all surviving wealth, payable over some thirty years, to compensate those the war had ruined. So even property that had “held” its real value was reached — by statute; only its physical form came through untouched. It was a broadly-supported burden-sharing levy rather than a seizure, but the effect on a saver’s balance sheet was the same: a claim rewritten by the state.
2.6 How the asset classes fared

Into the break. The break is the monetary collapse that ran to the June 1948 currency reform. Reichsmark cash and Reich war bonds were destroyed — accumulated savings were converted at under one new mark for ten old (a 90%-plus write-down) and the old Reich debt was repudiated. In the cigarette-and-barter economy before the reform the real money was anything outside the discredited currency: gold, foreign notes and tangible goods kept their value, shares (claims on surviving plant) held real value far better than paper, and physical property survived — later part-taxed by the 1952 equalisation-of-burdens levy, but never wiped.
The recovery. After 1948 the Deutsche Mark was hard money by design, and the winners flipped to the assets that ride growth. Equities led, carried by the Wirtschaftswunder’s roughly 8%-a-year real growth through the 1950s; reconstruction lifted real estate; and the new DM and the Federal Republic’s fresh bonds held their value once the 1953 London Agreement made the remaining debt serviceable. Gold and foreign currency — the shelters of the barter years — lost their edge as the DM hardened into one of the world’s strongest currencies.
3. The UK after WWII (1945–1975)
3.1 Context & baseline metrics
Britain came out of the Second World War carrying the largest debt in its history — around 250% of GDP in 1946–47 — the twin of Germany’s overhang in size, but nothing like it in kind. Where Germany’s state and currency had collapsed, Britain’s held: sterling still functioned, the institutions were intact, and default was never on the table. The debt was overwhelmingly domestic, long-dated, and denominated in Britain’s own currency — the protective profile Section 1 flags as the one that leaves the gentle exits open. Britain took them. It is the case that shows the slowest and least dramatic exit of all: not a reset, a haircut or a spike of inflation, but three decades of grinding the ratio down.
The “moment” here is not a break but a peak — 1946–47, the highest debt/GDP in British history and the point from which the long descent begins. There was no crisis event to date, and that absence is the case’s whole value: it is the control that shows the one exit the true crises never had room for, working in slow motion.
Table 4. The UK at the peak (1946–1947)
| Metric | At the peak | Note |
|---|---|---|
| Public debt / GDP | ~250% | The highest in British history — larger than any true-crisis case in this guide |
| Primary balance | Surpluses (peak ~6% of GDP, 1950) | Britain ran genuine primary surpluses through the 1950s |
| r − g | Persistently negative | Bank Rate pinned near 2%, below inflation and nominal growth — the repression engine |
| Inflation (CPI) | Moderate, high in the 1970s | Eroded the real value of fixed-rate war debt year after year |
| Currency & ownership | Sterling; mostly domestic | Own-currency, home-owned — the protective profile, no mismatch |
| Sovereign status | Intact | No default, no currency reset — the state and sterling held throughout |

3.2 Stages: from strain to resolution
Britain’s exit had no single event; it was a policy regime sustained for a generation. The build-up was the war itself — six years of borrowing that left the debt near 250% of GDP and about a third of GDP owed abroad, mostly to the United States, bridged in 1946 by the Anglo-American loan. The resolution then ran on three engines at once. Growth: post-war reconstruction and the long boom delivered roughly 2.5%-plus real growth a year, steadily expanding the denominator. Primary surpluses: through the 1950s the budget ran surpluses (peaking around 6% of GDP in 1950), so the state stopped adding to the stock. And — the quiet part — financial repression: Bretton Woods capital controls trapped domestic savings at home while the authorities held interest rates below the rate of inflation, so bondholders earned a negative real return and the real value of the debt melted away; Reinhart and Sbrancia estimate this “liquidation” ran at 3–4% of GDP a year for Britain and the US. The one wrinkle was the 1976 sterling crisis, when a balance-of-payments squeeze forced Britain to a then-record £2.3bn IMF loan — a reminder that even a grow-out is not always smooth — but by then the ratio was already near 50%.

3.3 Consequences — short and long term
There was no collapse, no savings wiped overnight — the cost was slow and hidden. Anyone who held gilts through the 1950s–70s earned a negative real return: their capital was quietly taxed by inflation and capped rates, a transfer from savers to the state spread thinly across a whole generation rather than concentrated in one brutal year. That is the case’s short-term signature — a cost so diffuse most of those who paid it never noticed. The long shadow is a proof and a caveat. The proof: a war-scale debt can be dissolved without a default, a restructuring or a currency reset — purely by keeping nominal growth above the cost of borrowing for long enough. The caveat: the method depended on conditions that no longer exist. The Bretton Woods capital controls that let Britain trap its savers were dismantled in the 1970s–80s, so a modern government with open capital markets cannot repress its way out the same way — and the 1976 IMF episode is the standing warning that the grow-out coexisted with recurrent sterling weakness.
3.4 Final result
Britain used adjust-and-grow as its primary exit — the only case in this guide where growth and primary surpluses carried the main load — but leaned on a quiet inflation component (financial repression’s negative real rates) and two managed currency devaluations, and never defaulted or restructured. The debt was neither cancelled like Germany’s nor written down like the crises that follow; it was outgrown, over thirty years, from ~250% of GDP to ~50%. The lesson for the synthesis is a corrective to the idea that growth is the exit everyone should want: the gentlest exit is real and it works, but it is slow, it needs the interest rate held below growth for decades, and in practice Britain’s rode on a hidden inflation tax that today’s open capital markets would not permit.
3.5 When the state rewrote the rules
Britain seized nothing outright, but the slow loss on gilts was a policy, not an accident. Under the Exchange Control Act 1947 — in force until 1979 — savings were trapped at home while the Bank Rate was held below inflation, so the negative real return that liquidated the debt was a rule the state set and kept for a generation (Reinhart & Sbrancia put the transfer at ~3–4% of GDP a year). Private gold holding was restricted for residents through the 1960s, closing that escape too. Financial repression is the decree channel wearing a quiet suit: no confiscation notice, just a set of rules that made the loss inevitable.
3.6 How the asset classes fared

| The recovery | Held | Won | Won | Held | Won | Hurt | |
Figure data: directional real-value verdicts for a domestic saver — a solid cell preserved or gained real value, a faint cell lost it. Britain never defaulted, so “the break” is the repression-and-inflation squeeze, not a default. Sources: the 1972–74 equity crash, Wikipedia (1973–74 stock market crash) ; the Barber-Boom house-price rise, Works in Progress ; the repression liquidation, Reinhart & Sbrancia (IMF WP/15/7) ; anchors in the paragraphs below.
Into the break. Britain never missed a payment, so “the break” is the long financial repression running into the 1970s inflation — a slow burn, not a single collapse. For three decades gilt-holders earned negative real returns; Reinhart & Sbrancia estimate the repression liquidated ~3–4% of GDP a year. The squeeze turned violent in the 1970s — inflation near 25% in 1975 — and the FT30 fell 73% from its April 1972 peak to its December 1974 trough. What preserved purchasing power sat outside sterling paper: house prices rose ~70% in real terms between September 1971 and July 1973 (the Barber Boom), gold soared once sterling floated after 1971, and two devaluations (1949, −30%; 1967, −14%) rewarded anyone holding dollars.
The recovery. From the mid-1970s the reset ran the other way. Gilts began their long bull as inflation and yields peaked, equities rebounded hard — the FT30 nearly doubled within months of the December 1974 low — and cash steadied as inflation was ground down through the 1980s. Property kept its real gains, while gold gave them back after its 1980 peak, turning the sharpest crisis hedge into the recovery’s laggard.
4. The US Great Inflation (1965–1982)
4.1 Context & baseline metrics
The United States is the contrast case, and it earns its place by not looking like a crisis. There was no default, no missed coupon, no restructuring — and the federal debt ratio actually fell across the period. What happened instead was that the dollar itself was devalued: first against gold, then in purchasing power, so the real burden of the outstanding debt was quietly eroded and the loss was spread across everyone holding dollars rather than concentrated on bondholders. The moment this guide dates it to is August 1971, when the US ended the dollar’s convertibility into gold — the admission that the outstanding stock of dollar claims could no longer be backed at $35 an ounce.
Table 6. The US — the burden erodes (1965 → peak)
| Metric | 1965 | Peak / 1980 | What moved |
|---|---|---|---|
| CPI inflation | ~1.6% | ~13.5% (1980 avg); 14.8% peak (Mar 1980) | The debt’s real value eroded through prices, not default |
| Federal debt held by public / GDP | ~38% | ~26% (late 1970s) | Fell — nominal growth outran the debt |
| Fed funds rate | ~4% | ~19% (1981 peak) | The Volcker stop that finally broke inflation |
| Gold | $35/oz (official) | ~$850/oz (Jan 1980) | The dollar’s gold value collapsed after 1971 |
| Dollar purchasing power | index = 100 | ~⅓ lost (1965–82) | Where the “default” actually landed |
| Unemployment | ~4% | ~10.8% (1982) | The cost of the disinflation |

4.2 Stages: from strain to resolution
The build-up was a decade of guns and butter — Vietnam and the Great Society spending against a gold peg that could not absorb the resulting dollar outflows. The 1971 Nixon shock closed the gold window and imposed wage-and-price controls; when the controls came off, the suppressed inflation surged, and the 1973 and 1979 oil shocks poured fuel on it. The result was stagflation — the toxic mix of stalled growth and double-digit inflation that Part 3 of the series treats in depth — running through the 1973–75 and 1980 recessions. The break came from the central bank, not the budget: appointed in 1979, Paul Volcker pushed the fed funds rate toward 20% and deliberately induced the deep 1981–82 recession, driving unemployment to nearly 11% but breaking the inflation, which fell from its 1980 peak to roughly 6% in 1982 and ~3% by 1983.

| 1973–75, 1980 | Recessions + stagflation | Weak growth and high inflation together; unemployment climbs |
| 1979–82 | Volcker disinflation | Fed funds toward 20%; the deliberate 1981–82 recession breaks inflation |
| 1982–83 | Disinflation | CPI falls to ~6% (1982), ~3% (1983); the new-era credibility begins |

4.3 Consequences — short and long term
The short-term cost was two recessions and a decade of eroded savings — the “malaise” era, in which anyone holding cash or long-dated bonds at a fixed rate was steadily expropriated by inflation. The long shadow is doctrinal. The episode created the modern central bank’s inflation-fighting mandate: the credibility that Volcker bought at the price of an 11% unemployment rate became the anchor of Fed policy for forty years. It also inaugurated the fiat, floating-rate era the whole world still lives in, the direct subject of Part 3. And it is the reason Part 1’s r − g framework matters so much: inflation is the quietest way a sovereign sheds real debt, because it never has to be announced.
4.4 Final result
The US used the one exit that never shows up on a default list — it inflated the burden away, then applied a hard monetary stop and let growth finish the job. The debt was never restructured and never missed a payment; instead the dollar lost roughly two-thirds of its 1965 purchasing power, and the “haircut” was taken by everyone who held dollars rather than by any identified creditor. The lesson for the synthesis: a sovereign that borrows in a currency it prints can always choose the inflation exit — which is exactly why the four cases that follow, none of which had that freedom, ended so much more violently.
4.5 When the state rewrote the rules
The starkest decree in the guide is American. Under Executive Order 6102 (1933), private gold ownership was banned — and it stayed illegal until 31 December 1974, so for most of the 1965–82 inflation the single asset that best held its value was one US citizens were legally forbidden to own. The 1971 closing of the gold window then rewrote the dollar’s promise to foreign holders. The “Gold — Won” verdict in Section 4.6 is real, but until the ban lifted it was reachable only through coins, jewellery or offshore accounts: the decree took the textbook hedge off the table for the ordinary saver.

The US never defaulted, so “the break” is the dollar’s debasement, not a default.

Into the break. Like Britain, the US never defaulted — the break is the erosion of the dollar itself. Cash lost roughly two-thirds of its purchasing power; the Dow sat near 990 in both 1966 and 1982 — flat in name, about −73% in real terms once divided by the CPI — and long bonds earned so little they were nicknamed “certificates of confiscation.” The winners were hard assets and anti-dollar bets: gold ran from $35 to $850 (January 1980, a 2,300%-plus gain), farmland roughly tripled ($137 to $737 an acre, 1970–80), and the dollar fell about 65% against the D-mark and 74% against the Swiss franc.
The recovery. The Volcker stop reversed every trade at once. The great bond bull began as yields peaked in 1981, equities launched the 1982 bull that ran for a generation, and cash regained a positive real return. The crisis hedges handed it all back: gold fell from $850 toward $300, the dollar surged through 1985, and the farmland boom collapsed into the 1980s farm-debt crisis — a real asset crushed once the inflation it hedged was gone.
5. Mexico 1982
5.1 Context & baseline metrics
Mexico is the emerging-market template — the case where someone else’s interest rate breaks your budget. Through the late 1970s Mexico borrowed heavily and cheaply, recycling the petrodollars that oil exporters had parked in Western banks, on the strength of a giant new oil field and a rising oil price. The catch was in the fine print: much of the debt was floating-rate and dollar-denominated. When the US Federal Reserve pushed rates toward 20% to break its own inflation (Section 4), the interest bill on Mexico’s whole debt stock repriced upward at once — and just as it did, the oil price that underwrote the borrowing began to fall. The moment is August 1982, when Finance Minister Jesús Silva Herzog told the Fed, the US Treasury and the IMF that Mexico could no longer service its debt — the event usually taken as the start of the international debt crisis. Mexico’s stress lived in its external-debt stock and the repricing of its rate, not a debt/GDP trajectory, so it is read here through the table rather than a chart.
Table 8. Mexico at the moment (1982)
| Metric | At the moment | Note |
|---|---|---|
| External debt | ~$80–86bn | Largely floating-rate and dollar-denominated |
| Real GDP per capita | −8.1% (1982), −9.1% (1983) | An oil boom flips to a deep bust |
| Inflation (CPI) | ~60% (1982) | On its way toward triple digits by the late 1980s |
| Peso devaluation | ~210% cumulative through 1982 | In steps: February, August, December |
| Oil | ~70% of exports | The price falls as US rates reprice the debt |
| US fed funds | ~19% (1981 peak) | Someone else’s rate repricing the whole stock |

5.2 Stages: from strain to resolution
Mexico could not print dollars, so its exit had to come from outside — a combination of emergency lending, austerity, and eventually a formal write-down. The immediate response was an IMF stand-by program with sharp fiscal tightening, and a long series of reschedulings negotiated with the syndicate of commercial banks that held the loans — a process that dragged on for years without ever restoring solvency. The durable fix arrived only in 1989 with the Brady Plan: US Treasury Secretary Nicholas Brady’s framework let debtor countries swap their bank loans for new, partly-collateralised bonds at a real reduction in principal. Mexico — first into the crisis in 1982 — was also the first to restructure under Brady, taking roughly a third off the value of some $48bn of bank debt and, in the process, inventing the template for every emerging-market debt deal since.

5.3 Consequences — short and long term
The short-term cost was severe: the peso collapsed, the government nationalised the banking system in 1982, and imports were compressed hard to force a trade surplus to service the debt. The long shadow was regional and institutional. For Latin America the 1980s became the lost decade — a stretch in which real GDP per capita across the region ended roughly where it began, as capital fled and new lending stopped. But the Brady resolution left a more constructive legacy: by turning defaulted bank loans into tradable bonds, it created the modern emerging-market bond asset class that today lets developing countries borrow from a global investor base rather than a handful of banks.
5.4 Final result
Mexico combined an external rescue (IMF, US Treasury), a restructure (the Brady write-down), and a currency reset by devaluation, with a dose of open inflation along the way — every exit except growth, which the lost decade denied it. The debt was neither inflated away as in the US nor cancelled outright as in Germany; it was renegotiated down over seven years with foreign help. The lesson for the synthesis: when the debt is in a currency you cannot print and an interest rate you do not set, the exit runs through your creditors and their governments — on their timetable, not yours.
5.5 When the state rewrote the rules
Mexico’s losses on cash were imposed, not merely inflated away. On 1 September 1982 the president nationalised the banking system by decree, and dollar-denominated deposits held in Mexican banks were forcibly converted into pesos at an off-market rate. Savers who thought a dollar account shielded them found the promise rewritten overnight; only dollars held physically or offshore stayed beyond the state’s reach — the first appearance of the guide’s recurring escape, value kept outside the system.

Into the break. The peso fell from 26 toward 150 per dollar across the 1980s — the first steps in 1982 alone roughly halved it — and the banks were nationalised in September 1982, so peso deposits and peso bonds were destroyed by devaluation and ~60% inflation. The only real shelter was outside the peso: actual dollars held offshore, and gold measured in pesos, preserved purchasing power, while dollar-priced property held its value but stopped trading. The Bolsa was a partial hedge only — it climbed in nominal pesos but was battered in real terms.
The recovery. The 1989–90 Brady deal turned the defaulted bank loans into tradable bonds that recovered, and the reopened market boomed: the Bolsa was among the best performers of the early 1990s, and property recovered with it. As the peso stabilised, the dollar-and-gold premium that had protected savers quietly disappeared — the crisis shelters became the recovery’s laggards.
6. Russia 1998
6.1 Context & baseline metrics
Russia is the case that breaks the rule the others seem to teach — that a government borrowing in its own currency need never default, because it can always print. Russia had its own currency, the ruble, and much of its debt was ruble-denominated: short-term treasury bills called GKOs. On the Section 1 checklist it held the protective card. It defaulted anyway. The set-up was a state that could not tax effectively, funding chronic deficits by rolling over ever more GKOs at ever-higher yields — a pyramid that worked only while buyers kept rolling. Foreigners piled in for the yield; by 1998 they held a large slice of a stock that had to be refinanced every few months.
Two shocks broke it. The 1997 Asian financial crisis drained emerging-market risk appetite, and the oil price collapsed to around $11 a barrel — gutting the export and tax revenue of a petro-state. As confidence went, GKO yields spiralled to 140–190%, which is not a borrowing cost but a run. The moment is 17 August 1998, when Russia did three things at once: defaulted on its ruble GKO debt, let the ruble devalue, and declared a 90-day moratorium on private foreign-debt payments. Russia’s stress lived in the fragility of a short-dated debt stock, not a high debt/GDP, so it is read here through the table rather than a chart.
Table 10. Russia at the moment (August 1998)
| Metric | At the moment | Note |
|---|---|---|
| Public debt | ~$200bn (~44% of GDP) | A moderate ratio — the debt was not large, it was short and fragile |
| Short-term GKO debt | ~$72.7bn | Ruble T-bills needing constant refinancing — the pyramid |
| GKO yield | 140–190% | Not a yield — a run; the market had stopped rolling the debt |
| Real GDP | −5.3% (1998) | Contraction into the default |
| Inflation (CPI) | ~84% (1998) | Spiked after the devaluation |
| Ruble | 6.3 → ~21 /USD | Roughly tripled by September 1998 |
| Oil (Urals) | ~$11–12/bbl | The petro-state’s revenue base collapsed |

6.2 Stages: from strain to resolution
Russia’s exit was the most abrupt in this guide — a simultaneous default-and-devaluation, not a negotiated way out. The build-up was the GKO pyramid of 1995–98: deficits financed by short-term ruble paper at yields that climbed as the stock grew. The IMF tried to bridge it — a roughly $22.6bn international package in July 1998, first tranche ~$4.8bn — and Russia attempted a voluntary swap of GKOs into longer dollar Eurobonds, which flopped. On 17 August the government defaulted on the GKOs, floated the ruble (which fell from about 6 to about 21 to the dollar within weeks) and imposed the foreign-debt moratorium. The shock rippled outward: in September the giant US hedge fund Long-Term Capital Management, wrong-footed by the default, had to be rescued in a Federal Reserve-organised bailout — the moment the crisis went global. Then the escape came from the two things the default itself unlocked: a cheap ruble made Russian output competitive, and the oil price recovered — driving a fast rebound (GDP +6.4% in 1999, +10% in 2000). The GKOs were restructured (the “novation”), and deals with the London and Paris Clubs followed.

6.3 Consequences — short and long term
The short-term cost was sharp: the ruble’s collapse and 84% inflation wiped out ruble savings and felled a banking system stuffed with GKOs; real wages fell, banks failed, and the government was dismissed. Ordinary Russians who had trusted the currency were expropriated as surely as any bondholder in a foreign-currency default — the own-currency shield did nothing to protect the saver from the devaluation. The long shadow has two parts. Domestically, the trauma reset Russian policy toward hard-money conservatism — reserve accumulation and an oil stabilisation fund that banked the 2000s windfall rather than spending it, so Russia entered later shocks a creditor rather than a debtor. Globally, the episode reset the price of emerging-market risk: the demonstration that a nuclear-armed state with its own currency would still choose to default, and the LTCM near-collapse it set off, taught markets that “own currency” was not the guarantee they had assumed.
6.4 Final result
Russia used a default — and the striking part is that it fell largely on its own-currency debt — together with a currency reset (the ruble devaluation) and a forced restructure (the GKO novation and the club deals), with an IMF rescue that arrived but failed to prevent the break. Recovery came not from any of the exits but from the devaluation and the oil price. The lesson for the synthesis refines the whole framework: a printing press makes default unlikely, not impossible. When the debt is short-term, high-yield and largely foreign-held, a government can decide that defaulting is cheaper than the hyperinflation it would take to honour the debt in freshly printed money — so borrowing in your own currency lowers the odds of a default without removing them.
6.5 When the state rewrote the rules
Russia’s losses came by administrative act. On 17 August 1998 the state froze the short-term GKOs, declared a ninety-day moratorium on private foreign-debt payments and let the ruble go — a default it chose over printing the rubles to repay, imposed on bondholders and depositors by decision rather than inability. Even an own-currency borrower, in other words, reaches for the decree when default is cheaper than the inflation honouring the debt would take; the only value beyond its reach was held outside the ruble.

Into the break. The ruble fell from 6.3 to about 21 per dollar and inflation hit 84%, wiping ruble deposits; the GKOs defaulted outright; and the RTS equity index collapsed roughly 90%, from 571 in October 1997 to about 59 by the end of 1998. Everything ruble-denominated — cash, bonds, stocks — was destroyed together, the rare case where domestic equities gave no shelter. Dollars and gold-in-rubles were the only refuge, and even property fell as the economy contracted.
The recovery. Then the same devaluation-and-oil combination that broke the country drove one of the world’s great rebounds. The RTS rose roughly ten-fold from its 1998 low over the next five years (175 by end-1999, 256 by end-2000), property boomed, and GDP grew +6.4% then +10%. The equities that had just been destroyed became the recovery’s clear leaders, restructured bonds normalised, and the dollar and gold gave back their edge as the ruble steadied.
7. Argentina 2001
7.1 Context & baseline metrics
Argentina is the case where the denomination of the debt, not its level, is the killer — and where a currency system defended past the point of no return turned a recession into the largest sovereign default of its era, over $100bn. In 1991 Argentina had beaten hyperinflation by law: the Convertibility regime fixed one peso to one US dollar, backed by hard-currency reserves. It worked, until it didn’t. Through the late 1990s a strengthening dollar dragged the pegged peso up with it, Brazil’s 1999 devaluation undercut Argentine exports, and the economy slid into a recession that the peg made impossible to escape — Argentina could not devalue to regain competitiveness, and could not inflate away debt denominated in dollars. On the surface the debt looked moderate — around 54% of GDP — but that ratio was a trap: it was dollar debt measured against a peso economy, and a devaluation would multiply it overnight. The moment is December 2001: bank runs, the freezing of deposits, riots, and default.
Figure 8. Argentina public debt / GDP, milestone years 2000–2007 (%)
Source: public-debt/GDP estimates from the IMF (IEO evaluation of the Argentina program) and CIGI analysis of the 2001 default. The 2002 leap is a devaluation effect, not new borrowing; the fall after 2005 reflects the restructuring. Milestone years; shading runs faint (low) to solid (the 2002 peak).
7.2 Stages: from strain to resolution
With no ability to devalue or inflate inside the peg, Argentina’s only exits were austerity — which failed — and then the two most disruptive moves available: default and the abandonment of the currency regime. IMF programs and a “zero-deficit” austerity law through 2000–01 could not restore confidence or growth. In December 2001 the government froze bank deposits (the corralito), triggering riots that toppled it; days later Argentina defaulted, and in January 2002 it abandoned convertibility, letting the peso fall to around three to the dollar. The debt was then restructured by force in two rounds — 2005 and 2010 — imposing one of the deepest haircuts in sovereign history (creditors recovered on the order of 30 cents on the dollar in present-value terms), with participation rising from about 76% to roughly 93% once holdouts were mopped up. A commodity-boom recovery then ran at 8–9% a year from 2003.

7.3 Consequences — short and long term
The short-term cost was social breakdown: poverty above 50%, five presidents in two weeks, and a middle class whose dollar savings were forcibly converted to devalued pesos (pesification). The long shadow is a reputation. Argentina’s default spawned more than a decade of holdout-creditor litigation that locked it out of international markets until 2016, and it did not end the pattern — the country defaulted again in 2014 and 2020, and chronic inflation returned. It became the standing example of the sovereign that reaches for the most disruptive exits because the currency regime it built left it no gentler ones.
7.4 Final result
Argentina used default, a currency reset (abandoning the peg), and a forced restructure, with the IMF’s pre-default rescue having failed rather than resolved. Recovery came from a commodity boom, not from any of the exits themselves. The lesson for the synthesis is the sharpest in this guide: a currency mismatch turns a moderate-looking debt ratio into an unpayable one the instant the peg breaks — the level on the page was never the real number.
7.5 When the state rewrote the rules
The market repriced the peso, but the decisive step was legislated. The December 2001 corralito froze bank withdrawals by decree; weeks later pesification, an emergency law, forcibly converted dollar deposits into pesos — rewriting by statute the banks’ contractual promise to return dollars, a conversion the Supreme Court upheld in 2004 after years of challenge. The magnitude is scored below; the point here is that it was imposed, not suffered — and, once again, only dollars held outside the banking system escaped the decree.

Figure data: directional real-value verdicts for a domestic saver — a solid cell preserved or gained real value, a faint cell lost it. The stock-market verdict is a nominal-peso devaluation hedge, flagged as such below. Sources: the corralito and pesification, Corralito (Wikipedia) ; the Merval’s crisis rally, ScienceDirect ; Buenos Aires property, Reporte Inmobiliario ; anchors in the paragraphs below.
Into the break. The corralito froze deposits and pesification converted dollar deposits at 1.4 pesos before the currency floated to about 3.8 — savers lost roughly 65% — while more than $100bn of bonds defaulted (recovery around 30 cents on the dollar). The escape hatches were dollars held outside the system, gold in pesos, and — strikingly — the stock market: the Merval rose about 217% in peso terms between November 2001 and March 2002 as a devaluation-and-capital-flight hedge. Dollar-priced property crashed, to about $1,026 a square metre in Buenos Aires by 2002, and transactions froze.
The recovery. The post-2003 commodity boom — GDP growth of 8–9% a year — lifted everything domestic: the Merval, the restructured bonds, and Buenos Aires property, which rewarded the dollar-holders who had bought at the bottom. As the peso settled near 3 to the dollar, the dollar premium faded and gold levelled off, so once again the crisis hedges handed leadership back to the paper claims.
8. Greece 2012
8.1 Context & baseline metrics
Greece is the currency-union case — a sovereign with all the fragility of Argentina’s dollar trap and none of the escape hatches, because it shared a currency it could neither devalue nor print. Euro entry in 2001 let Greece borrow at almost German interest rates, and it borrowed accordingly, on budget numbers that turned out to be false. The moment is the stretch from 2009 to 2012: in October 2009 an incoming government revised the 2009 deficit sharply upward — ultimately to around 15% of GDP, from the 6–8% previously reported — and the market repriced Greek risk violently, the credit-risk spread over the German Bund blowing out in exactly the way Part 2 describes, culminating in the March 2012 restructuring. Inside the euro, Greece had no independent central bank, no ability to devalue, and no lender of last resort of its own; its only tools were external help and internal austerity.
Figure 10. Greece general government debt / GDP, milestone years 2008–2018 (%)
Source: general government gross debt, Eurostat . The 2012 dip is the PSI restructuring; the renewed rise reflects a ~25% collapse in the GDP denominator. Milestone years; shading runs faint (low) to solid (the 2018 peak).
8.2 Stages: from strain to resolution
Greece’s exit was external rescue plus the largest restructuring in history, paid for with a depression’s worth of internal austerity. Two EU/IMF bailouts — €110bn in 2010 and €130bn in 2012 — kept the state funded in exchange for severe fiscal conditionality. The centrepiece was the March 2012 PSI (Private Sector Involvement): roughly €200bn of privately-held Greek bonds took a 53.5% cut to face value — about a 65–70% loss in present-value terms — the largest sovereign debt restructuring ever executed. Because Greece could not devalue, the competitiveness adjustment that Argentina got from a falling peso had to come instead through internal devaluation: wages and prices ground down inside the euro, at the cost of a 25% fall in output and 27.5% unemployment. Greece exited its bailout programs in 2018.

8.3 Consequences — short and long term
The short-term cost was a depression on the scale of the US 1930s: a quarter of output gone, more than a quarter of the workforce unemployed, mass youth emigration, and years of political upheaval. The long shadow is a lesson about debt service versus debt stock. Greece’s debt ratio remains around 180%, yet it is sustainable — because the official-sector loans that replaced its market debt carry very long maturities and near-zero rates, so the annual interest burden is modest despite the enormous stock. That is a direct restatement of Part 1’s point that the interest bill, not the headline number, is what binds. The crisis also hard-wired the euro’s implicit no-exit doctrine and built the permanent bailout machinery, the European Stability Mechanism.
8.4 Final result
Greece used an external rescue (EU/IMF), the largest-ever restructure (the PSI), and internal devaluation as its only form of adjustment — and had no access to the two exits that need a currency of one’s own, inflation and devaluation. The debt was neither inflated nor grown away; it was cut once by force and then made bearable by rewriting its terms. The lesson for the synthesis: inside a currency union, a member gets all of the discipline of a foreign-currency borrower and none of the escape valves — sustainability has to be manufactured through maturities and rates, because neither the stock nor the currency can be moved.
8.5 When the state rewrote the rules
Greece could not touch the currency, so it rewrote the bond contract instead. In February 2012 the Greek Bondholder Act inserted collective-action clauses retroactively into about €177bn of Greek-law bonds, binding holdout creditors into the restructuring scored below — a heavily-litigated use of legislation to force a “voluntary” deal. Capital controls in 2015 then rationed access to deposits that had kept their euro value. Here the decree fell on paper claims and account access, never on the currency — the mirror image of the emerging-market cases, and the reason Greece inverts the scorecard.
8.6 How the asset classes fared

Figure data: directional real-value verdicts for a domestic saver — a solid cell preserved or gained real value, a faint cell lost it. “Foreign currency” here means moving euros to a foreign bank or into Swiss francs, since Greece kept the euro.

Into the break. Greece is the row that inverts the grid, because the euro could not be devalued. Cash and deposits kept their value — the danger was access, not debasement: deposits were frozen under capital controls in 2015 but never redenominated or bailed in. The write-down fell on paper claims instead. The 2012 PSI cut Greek government bonds by 53.5% of face (~65–75% in present value), the largest sovereign restructuring ever, and the Athens index fell about 90% from its 2007 peak. Real estate fell ~42% between 2008 and 2017; gold, priced in a euro that never broke, sat near its record in 2011 but had no currency collapse to hedge.
The recovery. The reset ran through the bond market: post-PSI Greek 10-year yields fell from over 35% in 2012 to about 4% by 2018 — the famous recovery trade — so the restructured bonds led the rebound. Equities recovered only partly, the banks staying impaired; property kept falling to its 2017 trough; and gold in euros fell 30–40% from its 2011–12 peak. The lesson of the inverted grid is the sharpest in the guide: what a saver hedges is the currency breaking, and inside the euro it never did.
9. The five exits — a synthesis
Read together, the cases resolve into one framework. Every sovereign that cannot pay reaches for some combination of the same five exits, and which combination it can reach for is set by two structural facts: what currency the debt is in, and who owns it. A sovereign that borrows in its own currency from its own citizens (the US and Britain, Japan today) can reach for the gentle exits — inflating the burden away or outgrowing it; one that borrows in a foreign currency (Mexico, Argentina) or a shared one it cannot print (Greece) cannot, and is pushed toward restructuring and rescue. But own-currency is a strong shield, not an absolute one: Russia in 1998 held that card and defaulted anyway, because a short, high-yield, foreign-held debt made default cheaper than the inflation needed to honour it. Germany is the outlier that got all the generous exits at once — a currency reset and a write-down and external help — because its creditors had a Cold War reason to rebuild it; Britain is the one case where patient growth carried the main load, though even it leaned on a hidden inflation tax. And the framework has one more kind of case, the one this guide turns to next: the sovereign that carries a dangerous-looking debt and has not been forced to use any exit at all. Three live balance sheets test exactly that — Japan, the United States and France — read in the three sections after this one against these same five exits, before any exit has been forced.
Table 16. The cases compared
| Case | Peak debt burden | Trigger | Exit(s) used | Who paid | End state |
|---|---|---|---|---|---|
| Germany 1945–53 | ~300–400% of GDP (est.) | War destruction + overhang | Reset · restructure · rescue · grow | Savers (twice in 25 yrs) | Low debt, creditor nation, hard-money culture |
| UK 1945–75 | ~250% of GDP (1947) | War overhang, no market break | Grow · repress · (mild devalue) | Gilt-holders, via negative real rates | Debt ~50% by mid-1970s — the textbook grow-out |
| US 1965–82 | Ratio fell; ~⅔ of purchasing power lost | Gold peg + guns-and-butter + oil shocks | Inflate · hard stop · grow | Dollar-holders & savers | Fed inflation-fighting credibility; fiat era |
| Mexico 1982 | External debt unserviceable | Floating-rate + US rate shock + oil fall | Rescue · restructure · devalue | Taxpayers; foreign banks (via Brady) | Brady template; the EM bond market |
| Russia 1998 | ~$200bn (~44% of GDP) | GKO pyramid + oil slump + Asian contagion | Default · devalue · restructure | GKO holders (incl. foreign) & ruble savers | Fast oil-and-devaluation rebound; own-currency default |
| Argentina 2001 | ~54% → >150% post-devaluation | A peg defended too long | Default · devalue · restructure | Bondholders & savers (pesification) | Serial-default reputation; market exclusion |
| Greece 2012 | ~127% → >180% of GDP | A hidden deficit revealed, inside the euro | Rescue · restructure · internal devaluation | Bondholders, taxpayers, EU officialdom | Sustainable by terms not level; the ESM |
Source: as cited in Sections 2–8; peak-burden figures are the estimates and outturns from each case’s baseline table. The US row is measured in purchasing power because its debt ratio fell; Russia’s ratio was moderate — its debt was short and fragile, not large. The three live balance sheets (Japan, the US and France, Sections 10–12) are current and unresolved, so they take no row here.
The exits themselves map cleanly onto the cases — and the map is the payoff, because it shows which tools each situation actually left available.
Figure 12. Which exit each crisis used

| Russia 1998 | Minor | Primary | — | Primary | Partial | |
| Argentina 2001 | Minor | Primary | — | Primary | Minor | |

Figure data: the exit classification from each case’s Section 2.4–8.4 “Final result”; cell shading runs from “—” (not used) through Minor and Partial to Primary (the dominant exit). “Rescue” is marked “—” for Argentina and Russia because their pre-default IMF programs failed rather than resolved the crisis.
The grid maps only the seven resolved crises — Japan has used no exit and so takes no row — but its most revealing columns are exactly Japan’s escape valves. Only borrowers in a currency they print could inflate or grow their way out (the US and Britain here — and Japan, if it ever needed to), and only sovereigns with their own currency could reset it (Germany, Russia, Argentina, and Mexico by devaluation), while Greece, locked in the euro, was denied both and forced entirely onto restructuring, rescue and grinding internal adjustment. Restructuring is the near-universal tool; growth-and-adjustment appears everywhere but was the primary exit only for Britain — and even there it rode on a hidden inflation tax. Russia is the cautionary column: it held its own currency yet still defaulted, so “can inflate” means a lower probability of default, not immunity from it. Japan sits with the US and Britain on the safe side of both columns — which is why, if its debt ever did break, it would most likely break through the yen rather than through default.
9.1 The saver’s scorecard across the cases
Read the seven cases as one portfolio question — where should a saver have been? — and a pattern emerges that no single case shows on its own: the winners reverse at the reset. Figure 13 scores each asset class into the break; Figure 14 scores the same six through the recovery, both in real, purchasing-power terms for a domestic saver.
Into the break, the solid cells cluster on the right. Gold and foreign currency held or gained in every case whose currency broke, and cash and government bonds — the two paper claims — were the reliable losers, wiped outright wherever the exit ran through inflation, default or devaluation. Through the recovery the solid cells migrate left: once the write-down was done, it was equities and the restructured bonds — the very paper that had just been cut — that led the rebound, while gold and hard currency gave back.

Figure data: the “into the break” verdicts from the per-case scorecards in Sections 2.6, 3.6, 4.6, 5.6, 6.6, 7.6 and 8.6, where each is argued with sourced figures. Directional real-value verdicts for a domestic saver — a solid cell preserved or gained real (purchasing-power) value, a faint cell lost it (Won · Held · Mixed · Hurt · Wiped). “Foreign currency” means holding a hard currency other than the sovereign’s own; Japan (Section 10) takes no row — it has had no break.
Two columns carry the qualifications the grid makes visible. Domestic stocks are a nominal-not-real hedge — Argentina’s Merval rose 217% in pesos into the break while the currency fell two-thirds — so they protect a local saver but flatter to deceive anyone measuring in dollars. Real estate holds against pure inflation (US farmland, UK houses) but crashes in a banking collapse (Greece, Argentina), so “real asset” is not a synonym for “safe.” And Greece is the row that inverts the whole grid: the one case where the currency held, so cash was safe and the real assets fell — the standing reminder that what a hedge protects against is the currency breaking, not the crisis itself.

Figure data: the “recovery” verdicts from the same per-case scorecards (Sections 2.6–8.6); the scale, conventions and Japan’s exclusion are as in Figure 13. The recovery boundary is each case’s reset — the 1948 reform (Germany), the Volcker turn (US), Brady (Mexico), the 1998 float (Russia), the 2002 float (Argentina) and the 2012 PSI (Greece); the UK’s is the mid-1970s.
9.2 The other channel — loss by decree
The scorecards read the market channel: how prices repriced each asset. But in most of these cases the decisive losses were imposed by the state directly — a law, a decree or an emergency freeze that changed the terms rather than waiting for the market to. Table 17 lines up the instrument in each case.
Table 17. Loss by decree — the state’s instrument in each case
| Case | Instrument | What was taken | From whom |
|---|---|---|---|
| Germany 1948 & 1952 | Currency conversion; wealth levy (Lastenausgleich) | ~90% of RM savings; ~50% of surviving wealth | Savers; property owners |
| UK 1947–79 | Exchange controls; sub-inflation rate caps | Real value of savings and gilts (~3–4% of GDP a year) | Savers, gilt-holders |
| US 1933–74 | Gold-ownership ban; 1971 gold-window closure | Access to the hedge itself | Citizens; foreign dollar-holders |
| Mexico 1982 | Bank nationalisation; forced peso conversion | The banks; dollar deposits’ value | Shareholders; depositors |
| Russia 1998 | Own-currency default; GKO freeze + moratorium | Ruble bonds and deposits | Bondholders; depositors |
| Argentina 2001–02 | Corralito freeze; pesification | Deposit access, then ~65% of deposit value | Depositors |
| Greece 2012 & 2015 | Retroactive CACs; capital controls | 53.5% of bond face; deposit access | Bondholders; depositors |
Source: per-case detail and links in Sections 2.5–8.5. Key instruments: Germany’s Lastenausgleich (1952); the US gold-ownership ban (1933–1974); the Greek Bondholder Act (2012); Argentina’s corralito . Legitimacy varied widely — the Lastenausgleich was a broadly-supported burden-sharing levy, the retrofit CACs and pesification were litigated for years — so the ledger names instruments, not verdicts.
Two lessons fall out. First, the decree channel is the one that defeats the very hedges the scorecards reward: the United States banned the gold that “won,” Argentina seized the dollar deposits that were the escape, and Greece rewrote the bond contract itself. Second, it explains the one shelter every emerging-market case shared — value held outside the system: dollars offshore rather than in a local bank, and assets in a custody or jurisdiction the state could not reach overnight. Asset class hedges the market channel; custody and jurisdiction hedge the decree channel — and they are different questions, which is why the strongest historical position paired a real asset with a place the rules could not easily be rewritten around it.
There is one observation every case shares, and it is the bridge to the rest of the monetary system. Every exit except unaided growth wrote down someone’s claim on paper money — savers in Germany, dollar-holders in the US, British gilt-holders through years of negative real returns (the repression that did the quiet work behind the grow-out), bondholders in Mexico, Argentina and Greece, and GKO holders and ruble savers in Russia. That is the structural reason real assets — gold and the commodities screened on Metal Pilot — have historically been sought as a hedge against the money itself being the variable that gives way, a theme the series picks up in Part 3 and in the guide to de-dollarization . None of that is a recommendation; it is the mechanism the cases have in common.
10. Japan: the crisis that hasn’t happened
The nine sections above build the framework and close the settled history. The last three turn it on balance sheets that are still open — three sovereigns carrying dangerous-looking debt today without (yet) a crisis, read against the same five exits before any has been forced: Japan here, then the United States (Section 11) and France (Section 12). Everything in these three sections is current and dated, and the forward risks are scenarios, not forecasts — the deliberate exception to a guide otherwise made of finished history. Japan leads because it is the extreme: the highest debt load in the guide by a wide margin, and yet a sovereign that has never defaulted, never restructured, and never lost the confidence of its lenders — the standing test of whether the framework predicts a crisis or merely explains its absence.
10.1 The numbers, today
Japan’s gross government debt is around 207% of GDP — the largest in the world, and about four times Argentina’s ratio when it defaulted in 2001. On the raw number it looks like the most dangerous balance sheet in this guide. Yet Japanese government bonds (JGBs) trade as a haven, the state funds itself easily, and no market has ever forced Tokyo’s hand. The paradox is the point: this is the debt level that “should” have caused a crisis on any simple reading of Sections 2–8, and did not.
Table 18. Japan today (2025–2026)
| Metric | Latest | Note |
|---|---|---|
| Gross debt / GDP | ~207% (2025) | The world’s highest; net debt is far lower (~136%) as the state owes much to itself |
| BoJ share of JGBs | ~53% | The central bank is the single largest creditor — a record high |
| Domestic ownership | ~90% | Japan owes itself, in its own currency |
| Policy rate | 1.0% (mid-2026) | Up from −0.1%; negative rates and yield curve control ended March 2024 |
| 10-year JGB yield | ~2.5% | Up from near-0% under yield curve control |
| Debt servicing | ~¼ of the FY2026 budget | ~¥36.6tn; the assumed interest rate was raised to 3.0%, from 2.0% a year earlier |

Current figures — re-source before reuse.
10.2 Why it hasn’t broken
Japan is safe on precisely the axes that sank the five true crises. First, it borrows in its own currency, which it can print — the US privilege, not the Greek or Argentine trap; a forced default is close to impossible when the debt is in yen and the central bank can always be the buyer of last resort. Second, roughly 90% of JGBs are held domestically — Japan owes itself, not foreign creditors who can flee at the first tremor, and the BoJ alone holds about 53%, so more than half the “debt” is one arm of the state owing another — which is why net debt sits far below the gross headline. Third, for two decades r stayed below g even at near-zero growth, because the interest rate was pinned near zero: the interest bill on ~207% of GDP is trivial when the coupon is a fraction of a percent. Read against Part 1’s checklist, Japan holds every protective card at once — own currency, domestic ownership, a captive central bank, and a near-zero cost of carry.
10.3 The forward risks — what would change the verdict
The reason Japan is a future problem rather than a historical one is that those shock absorbers are wearing thin. The BoJ ended negative rates and yield curve control — its cap on long-term bond yields — in 2024 and has raised its policy rate to 1.0% by mid-2026, with the 10-year JGB yield climbing from near zero to about 2.5%. On a ~207%-of-GDP stock, a small rise in the average coupon is a large rise in the interest bill — and it feeds through slowly, as old low-rate bonds mature and are refinanced at the new rate. The mechanism is already visible in the budget: Japan’s FY2026 plan earmarks roughly a quarter of all spending for debt servicing and assumes a 3% rate, up from 2% a year earlier. That is the r in r − g turning against Japan for the first time in a generation — and it happens just as demographics drain the savings pool that funded the debt cheaply. A shrinking, ageing population runs down its savings and pushes up the social-security bill, already a third of the budget; if domestic buyers thin out, more JGBs must go to foreigners (which reintroduces the flight risk Japan has been spared) or be absorbed by the BoJ (monetary financing — the central bank funding the state by buying its debt — which pressures an already-weak yen).
Figure 15. Japan gross government debt / GDP, milestone years 2000–2025 (%)
Source: gross general government debt, IMF World Economic Outlook database. Milestone years; the 2020 peak reflects the pandemic, and the recent easing is a nominal-GDP (inflation) effect, not debt reduction. Shading runs faint (low) to solid (the 2020 peak).
None of this predicts a Japanese default — it is the mechanism by which the conditions that kept Japan safe could erode. Japan has used none of the five exits, because it has never been forced to; the open question is which one it would reach for if the interest burden kept climbing. Its currency is its own, so the inflation exit is always available — which is exactly why a Japanese crisis, if it ever came, would most likely look like the US in Section 4 (a debasement of the yen) rather than the default of Greece or Argentina. Japan is the reminder that the framework cuts both ways: the same features that make a debt survivable are the ones whose reversal would make even a sovereign that has never missed a payment fragile. And because such a break would come through the yen rather than through default, its hedges would be the US column of the scorecards above — gold in yen (already at record highs), foreign assets and other real stores of value — not the restructured-bond and local-equity trades that led the recoveries in the default cases. That is a scenario, not a forecast, and Japan takes no row in the cross-case grids above (Figures 13–14).
11. The United States: the privilege being tested
The United States is where the framework turns back on the country that supplied its cleanest control case. In 1965–82 (Section 4) it ran the inflation exit to the letter — never missing a payment, letting the dollar shed two-thirds of its value — and it can always run it again, because it borrows in the currency the whole world uses. That is the exorbitant privilege: the issuer of the global reserve currency (the money other states hold in their own reserves and invoice trade in) can always be the buyer of its own debt, so a forced default is a choice, never a necessity. What makes the US a live case in 2026 is not that the privilege is gone — it is that the arithmetic behind it is deteriorating faster than at any time outside a war, on the one balance sheet the rest of the system is anchored to.
11.1 The numbers, today
The federal government crossed $40 trillion of gross debt in August 2026, and the flow behind the stock is not slowing: the deficit is running near 6% of GDP with the economy at full employment, and — the number that changed the conversation — net interest now costs more than national defense. On any simple reading this is a balance sheet moving the wrong way; what holds it up comes next.
Table 19. The United States today (2025–2026)
| Metric | Latest | Note |
|---|---|---|
| Gross federal debt | >$40tn (Aug 2026) | Crossed $40tn for the first time — the headline stock |

Current figures — re-source before reuse.
11.2 Why the privilege holds
Read against Part 1’s checklist, the US holds the strongest hand in this guide — stronger even than Japan’s — because it is the issuer of the asset everyone else runs to. It borrows in its own currency, which it prints, so the inflation exit is permanently open and a forced default is close to impossible. Its bond market is the deepest and most liquid in the world, and Treasuries are the global risk-free asset, so a crisis anywhere tends to push money into dollars, not out — the opposite of the capital flight that broke Mexico, Russia and Argentina. Roughly 70% of the public debt is held domestically, the Federal Reserve alone holding about 14%, and the dollar is still the currency the rest of the world saves in. This is the privilege the 1965–82 episode already demonstrated in reverse: the US shed a third of its real debt through inflation without a single missed coupon, and the “haircut” fell on everyone holding dollars rather than on any named creditor.
11.3 The forward risks — what would change the verdict
The privilege is a cushion, not immunity — and every part of it is being leaned on at once. The deficit is structural, near 6% of GDP with unemployment low, so it does not close on its own as a cyclical one would. The interest bill is now compounding: the marketable debt is refinancing out of the sub-2% coupons of the 2010s into a ~4.8% market, so net interest — already past defense and ~19% of revenue — climbs even if the stock stood still, the r in r − g turning against the US just as it has against Japan. The CBO projects debt held by the public rising from ~99% of GDP to 108% by 2030 and 120% by 2036; Moody’s, stripping the last AAA in May 2025, models gross federal debt reaching ~134% by 2035. Two channels Japan does not share sharpen the risk: about 30% of the tradable debt is foreign-held, a flight valve if reserve demand ever fades, and the US carries a recurring political fault line — debt-ceiling brinkmanship and shutdown standoffs that can manufacture a technical default on debt that is entirely payable. None of this predicts a US default; Treasuries remain the world’s haven and the inflation exit stays open. But Russia (Section 6) is the standing proof that an own-currency borrower can still break, and the shape of any US break is the one its own history already drew — a debasement of the dollar, as in Section 4, not a Greek-style default — so a saver’s hedges would be the US column of Figure 13: gold, foreign assets and real stores of value, not the local paper that leads a post-default recovery. That is a scenario, not a forecast.

Shading runs faint (low) to solid (the recent peak).
12. France: the core without a printing press
France is the mirror image of Japan and the United States, and the reason sits on Section 1’s decisive axis. It is a large, rich, core economy — the euro area’s second-largest — but it does not have its own printing press. Its debt is in euros, a currency France shares across the euro area and cannot itself create; the European Central Bank serves the whole union and is barred from financing any single member. So France holds the Greek card, not the American one: it carries the fragility of a borrower that cannot be its own lender of last resort. It is the live test of whether a core euro sovereign can carry peripheral-scale debt — and a politics that cannot agree a budget — without the market forcing the question Greece faced in Section 8.
12.1 The numbers, today
France’s public debt passed €3.5 trillion in 2025 and reached 115.6% of GDP, climbing again to 117.5% by the first quarter of 2026 — the euro area’s third-heaviest ratio after Greece and Italy, and nearly twice the bloc’s 60%-of-GDP Maastricht ceiling (the debt limit written into EU treaty law). The deficit is narrowing but still wide, and the cost of carrying the debt has become the budget’s fastest-growing line.

12.2 Why it’s fragile where Japan is safe
Take Japan’s protective checklist and invert it. France cannot print the currency its debt is in — the ECB backs the euro system, not any single member’s budget, and is forbidden from monetary financing (a central bank funding its government by buying its debt), so there is no domestic buyer of last resort standing behind French bonds the way the Bank of Japan stands behind JGBs. Ownership is roughly half foreign, not 90% domestic, so a loss of confidence can walk out the door. And the third leg — the political one — is where France is most exposed: since the 2024 snap election the National Assembly has split into three blocs with no majority, and successive prime ministers have fallen over the budget. Michel Barnier’s government collapsed in December 2024; François Bayrou was toppled 364–194 in September 2025 over a ~€44bn consolidation package; his successor, Sébastien Lecornu, pushed the 2026 budget through only via Article 49.3 — the constitutional device that adopts a bill without a vote — after months of deadlock. This is the Greek profile of Section 8 inside a core economy: a sovereign that cannot devalue, cannot print, and cannot legislate the cuts its own targets require. What France has that Greece did not is the ECB’s implicit backstop — the Transmission Protection Instrument, a standing pledge to buy a member’s bonds if its spreads widen “unwarrantedly” — and sheer size: France is too large to be rescued on Greek terms, which is both a reassurance and a threat.
12.3 The forward risks — what would change the verdict
The interest bill is compounding faster in France than anywhere else in this cluster: debt servicing has gone from about €36bn in 2020 to roughly €59bn in 2026, overtaking defense, as low-coupon OATs refinance near 3.9%. The debt ratio is still rising, and the path to the 3%-of-GDP deficit promised for 2029 runs through exactly the cuts a hung parliament keeps rejecting. The gauge to watch is the OAT–Bund spread — the extra yield investors demand to hold French rather than German ten-year debt, the credit-risk spread Part 2 anatomises. At ~80 basis points it is level with Italy and calm for now, but it reprices on headlines, and a failed budget or a doubted ECB backstop is where a French crisis would first appear — the same repricing that opened Greece’s. The deeper constraint is structural: inside the euro, France is denied the two exits that need a currency of one’s own, inflation and devaluation, so a forced French adjustment would look like Greece’s — restructuring and grinding internal adjustment — not the American or Japanese inflation route. Its saver’s hedges would therefore sit in the Greece column of Figure 13: if the euro holds, cash keeps its value and the danger is the bond and the bank, not debasement. None of this is a prediction — France funds itself easily, the ECB backstop is real, and the deficit is narrowing. It is the live case of a core euro sovereign carrying peripheral-scale debt, and the standing test of whether the currency union’s centre is as safe as its size suggests. That is a scenario, not a forecast.

Milestone years; the 2020 peak reflects the pandemic and the easing to 2025 is a nominal-GDP effect, not debt reduction — the ratio was back above 117% by Q1 2026. Shading runs faint (low) to solid (the 2020 peak).
13. Summary
There is no single debt level that marks the edge of sustainability, and no crisis has ever had one cause. What the cases share is a small toolkit: a government that cannot pay must inflate the debt away, restructure it, secure an external rescue, reset or devalue its currency, or adjust and grow — and every historical episode is a named combination of those five, chosen not freely but according to what the country’s currency and creditors allowed.
Germany, carrying the highest debt in the guide, got the most generous resolution — a 1948 currency reset and a 1953 write-down, backed by Cold War allies — and emerged a low-debt creditor with a permanent horror of inflation. The US never defaulted at all: it let the dollar lose two-thirds of its value, moved the burden from bondholders to everyone holding cash, and bought the Fed four decades of credibility with the Volcker recession. Britain, buried under a war debt of ~250% of GDP, never defaulted either — it outgrew the debt over thirty years, helped by primary surpluses and the quiet negative-real-rate “repression” that taxed its bondholders slowly rather than its citizens all at once. Mexico and Argentina show the foreign-currency trap from two angles — a floating-rate rate shock and a peg defended too long — where a moderate-looking debt ratio was really an unpayable one the moment the currency moved, and the exit ran through the IMF, the banks and a forced haircut. Russia in 1998 is the exception that sharpens the rule: it borrowed in its own currency — the one profile that is supposed to rule out default — and defaulted anyway, because its debt was short, its yields had become a run, and its buyers were fleeing, so default was cheaper than the inflation honouring it would have required. Greece shows the currency-union version: all of the fragility, none of the escape valves, resolved by the largest restructuring in history and a depression’s worth of internal austerity, and left sustainable by its terms rather than its level. And the three live cases carry the framework into the present. Japan is the counter-case that proves the rule — the highest debt of all, yet no crisis, because it borrows in its own currency from its own people at rates that were, until now, near zero. The United States holds that same own-currency shield in its strongest form, the reserve-currency privilege that lets it always reach the inflation exit, but on a deficit and an interest bill deteriorating faster than at any time outside a war. France holds the opposite card — a core economy with no printing press of its own, carrying peripheral-scale debt through a hung parliament, the Greek trap in a larger frame. None of the three is a forecast of crisis; each is a warning that the protective factors are the very ones that rising rates, ageing populations and shared currencies are beginning to erode.
Laid across the seven cases as one portfolio, the asset pattern is consistent: gold and hard currency held into every break whose currency gave way, cash and government bonds were the losers, and then equities and the restructured bonds led the recoveries — with Greece, where the euro held, the lone inversion (Sections 2.6–8.6). And in most cases that loss was imposed by decree as much as by the market — a gold ban, a deposit freeze, a rewritten bond contract (Table 17) — so what protected a saver was as much where value was held as what it was held in. The through-line back to Part 1 is that the structure of a debt matters more than its size: the currency it is in, who owns it, and whether the interest bill — not the stock — can be carried. And the through-line onward is that every exit but growth devalues someone’s paper claim, which is why the questions these cases raise about any government’s balance sheet lead naturally to the harder-asset data on Metal Pilot .

15. Sources, methodology & disclaimer
15.1 Sources, methodology & data vintage
This guide is a companion to the three-part series The Monetary System — Part 1 · Spending & Debt , Part 2 · Bonds & Yields and Part 3 · Interest Rates & Inflation — and uses its metric vocabulary and framework. Figures for the seven historical cases (Sections 2–8) are historical outturns, sourced to recognised statistical, institutional and scholarly bodies; the three live sections (Japan, the US and France — Sections 10–12) carry current figures and forward scenarios, not settled history. The source is named beneath each table and figure. Data as of August 2026; the history is final and the live-case figures are point-in-time, so re-verify against the primary source before reuse.
Primary sources by case: Germany — Deutsche Bundesbank monetary-history material, the IMF on the 1948 reform, and economic-history work on the 1953 London Debt Agreement (CEPR ); UK — Bank of England, A Millennium of Macroeconomic Data and the OBR (post-war debt), with Reinhart & Sbrancia (IMF WP/15/7) on financial repression and the debt liquidation; US — U.S. BLS (CPI), Federal Reserve History and the Federal Reserve (rates), FRED /OMB (federal debt); Mexico — Federal Reserve History , World Bank IDS , EMTA and the IMF ; Russia — IMF, Russia Rebounds , the Yale ICF case study , and the Economics Observatory ; Argentina — the IMF IEO 2004 evaluation, CIGI , and CRS ; Greece — Eurostat /ELSTAT, the ESM , and the IMF ; Japan — the IMF World Economic Outlook (debt/GDP), the Bank of Japan (policy rate, JGB holdings), Nippon.com (BoJ 53% JGB share) and Japan’s Ministry of Finance via Nippon.com /The Japan Times (FY2026 debt servicing); United States — the CBO Budget and Economic Outlook 2026–2036 (debt, deficit, projections), CRFB and CBO (interest vs. defense, FY2025), the Federal Reserve (yields and policy rate) and Moody’s (the May 2025 downgrade); France — Insee (debt and deficit), Agence France Trésor and Euronews (debt servicing), ING (the OAT–Bund spread) and S&P /Fitch /Moody’s (ratings).
Methodology and caveats. “The moment” dated for each case is a judgement call, stated with its reason in the case text. Pre-1950 German national accounts are academic reconstructions and are labelled estimates. UK debt/GDP for the intermediate milestone years draws on the Bank of England long-run series and is treated as an estimate (magnitudes, not decimals), with only the 1947 peak and the 1971/72 reading fixed to the cited studies. Russia’s headline debt ratio was moderate — the case is read through the fragility of a short-dated stock, not a high debt/GDP. Argentina’s official inflation statistics for 2007–2015 were censured by the IMF and are avoided for that window. Debt-to-GDP figures across cases draw on different national and institutional bases and are not perfectly comparable; they are used to show direction and magnitude, not to rank countries to the decimal. The three live sections (Japan, the US and France) describe current conditions and forward risks; those risks are framed as scenarios, and nothing in them is a prediction of a crisis. Worked ratios illustrate the mechanism and are not forecasts. The per-case asset scorecards (Sections 2.6–8.6) and the two cross-case grids (Figures 13–14) are directional real-value verdicts for a domestic saver — Won / Held / Mixed / Hurt / Wiped, scored in purchasing-power terms — not measured total returns; each cell is substantiated with sourced figures in the case’s own text, and the real-estate column in particular rests on partial house- and land-price series and is treated as directional.
