In short

In 1971 Nixon closed the gold window and the Bretton Woods system began to collapse. Full timeline from 1944 to the 1973 float, and what it means in 2026.

Latest Story

For nearly three decades after the Second World War, one promise held the world’s money together: foreign governments could exchange their US dollars for American gold at $35 an ounce, and every other major currency was pegged to the dollar. On 15 August 1971 Richard Nixon withdrew that promise. The Bretton Woods collapse did not happen in a single night, since governments spent another 19 months trying to save fixed exchange rates, but by March 1973 the major currencies were floating. This timeline traces how the system was built, why it cracked and what replaced it, through to the gold and reserve-currency debates of 2026.

💡 Short Answer

The Bretton Woods system, agreed by 44 nations in July 1944, fixed currencies to the US dollar and the dollar to gold at $35 an ounce for foreign governments. As dollars piled up abroad and US inflation rose, that promise became impossible to keep. Nixon suspended gold convertibility on 15 August 1971. The Smithsonian Agreement tried to restore fixed rates in December 1971, but it broke down, and the major currencies floated from March 1973.

Bretton Woods Collapse: Key Questions

What caused the collapse of Bretton Woods?
Foreign official dollar holdings grew larger than the US gold stock, US inflation rose in the late 1960s and speculators bet on a dollar devaluation. Defending the $35 gold price became impossible, so the United States suspended gold convertibility in August 1971.
When did the US end the gold standard?
Domestic gold convertibility ended in 1933. The last link, the promise to convert foreign official dollars into gold at $35 an ounce, was suspended by Richard Nixon on 15 August 1971 and never restored. The IMF abolished gold’s official price in 1978.
What was the Smithsonian Agreement?
A December 1971 deal among the Group of Ten that devalued the dollar, raising the official gold price from $35 to $38, revalued other currencies and widened trading bands to 2.25%. It collapsed within 15 months.
What replaced the Bretton Woods system?
Floating and managed exchange rates. The major currencies floated from March 1973, and the IMF’s Jamaica reforms of 1976, in force from 1 April 1978, allowed members to choose their own exchange-rate arrangements without gold as an anchor.
📚 Key Takeaways

The End of Bretton Woods in Ten Points

  • The bargain: currencies pegged to the dollar, the dollar convertible into gold at $35 for foreign official holders.
  • A short life: it only worked as designed from 1958, when European currencies became convertible, to 1971.
  • The flaw: the world needed more dollars, but more dollars abroad made the gold promise less credible, the Triffin dilemma.
  • The warning signs: gold at $40 in 1960, the 1961 Gold Pool, sterling’s 1967 devaluation and the 1968 two-tier market.
  • The break: after the German mark floated in May 1971, Nixon closed the gold window on 15 August 1971.
  • Not just gold: the same speech froze wages and prices for 90 days and added a 10% import surcharge.
  • The rescue that failed: the Smithsonian Agreement set gold at $38, but lasted only 15 months.
  • The end: a second devaluation to $42.22 in February 1973, then the general float in March.
  • The formal close: the IMF’s Second Amendment legalised floating on 1 April 1978.
  • The legacy in 2026: the dollar still dominates reserves at 56.70%, while gold, now about $4,182, is back in central bank vaults.

Gold near $4,200, and the books still say $42.22 2026

Spot gold about $4,182 an ounceRoughly 119 times the old $35 priceTreasury revaluation talk is speculation only

Gold traded at about $4,182 an ounce on the morning of 13 October 2026, about a quarter below its January record. The US Treasury still carries its gold, about 261.5 million troy ounces, at the statutory price of $42.22 set in 1973, a book value of roughly $11 billion against a market value above $1 trillion. Some analysts argue a revaluation could come; on 14 October Kitco quoted UBP’s Peter Kinsella calling it an ‘upside risk’ for gold. No official proposal has been made.

The $42.22 figure is the last official gold price ever set by the United States, a direct leftover of the 1973 devaluation.

IMF: the dollar’s reserve share edges down to 56.70% 2026

COFER data for Q2 2026Dollar 56.70% (57.18% in Q1)Euro 20.60%; total reserves $13.22 trillion

The IMF’s Currency Composition of Official Foreign Exchange Reserves showed the dollar’s share slipping again, as holdings of the euro and other currencies grew while dollar claims were largely unchanged. Fifty-five years after the gold link ended, the dollar remains by far the largest reserve currency, but well below the roughly 71% share it held around the euro’s launch in 1999.

55 years since the gold window closed 2026

Anniversary of the Nixon ShockGold up more than a hundredfold since 1971Debate over the dollar’s role revived

The 55th anniversary of Nixon’s address drew commentary from economists and gold dealers alike, much of it framed around record gold buying by central banks, tariffs and the size of US government debt. Unlike 1971, there is no peg to defend: the dollar’s value is set in markets, and its reserve role rests on US financial markets rather than a claim on gold.

ECB: gold’s share of reserves passes US Treasuries Gold

ECB report on the international role of the euroGold about 27% of global central bank reserves at end-2025US Treasuries about 22%

The European Central Bank’s annual report found gold had risen to about 27% of global official reserves at the end of 2025, from about 20% a year earlier, while US Treasuries fell to about 22%. The report noted that much of the change reflected gold’s price surge, roughly 60% in 2025, and that central banks were still buying heavily. Many have cited the 2022 freezing of Russia’s reserves as a reason to hold more gold.

Gold hit its all-time high in late January 2026 amid geopolitical tension, tariff threats, a weaker dollar and questions about the Federal Reserve’s independence. It then fell back, trading roughly 25% lower by October. The record was more than 150 times the $35 official price abandoned in 1971.

Calls for a ‘new Bretton Woods’ Crisis

Global financial crisisFrench and British leaders call for reformG20 leaders meet in Washington, November 2008

As the financial crisis spread, European leaders including Nicolas Sarkozy and Gordon Brown called for a ‘new Bretton Woods’ to remake global financial rules. The first G20 leaders’ summit followed in Washington in November 2008. It produced new financial regulation and a larger IMF, not a return to fixed exchange rates.

After the dollar’s steep rise in the early 1980s, the finance ministers of the United States, Japan, West Germany, France and the United Kingdom agreed to coordinate intervention to weaken it. It showed how the post-Bretton Woods world worked: no pegs, but governments still trying to steer exchange rates.

Released from its peg, gold rose through the 1970s as US inflation climbed and the dollar weakened. It touched $850 an ounce in January 1980. Paul Volcker, who had helped close the gold window as a Treasury official in 1971, became Fed chairman in 1979 and raised interest rates sharply to break inflation.

After another wave of selling of the dollar, European exchange markets closed in early March. The G10 approved an arrangement in which six European Community currencies moved together while floating against the dollar. When markets reopened on 19 March, the Bretton Woods fixed-rate system was over in practice.

The State Department’s historians count just 15 months between the Smithsonian Agreement and the February 1973 devaluation.

Speculation against the pound forced Britain to let it float, an early crack in the Smithsonian arrangement. During 1972 speculators pushed many European currencies to the tops of their wider bands, and the free-market price of gold climbed to about $60 an ounce.

The Smithsonian Agreement Agreement

G10 meets at the Smithsonian InstitutionGold raised from $35 to $38Bands widened to 2.25%; US surcharge removed

The Group of Ten agreed new central rates. The dollar was devalued against gold, and the yen, mark and other currencies were revalued, for an average dollar devaluation of about 10.7% against the key currencies according to the Federal Reserve’s historians. Permitted fluctuations widened from 1% to 2.25% either side of the new rates, and the United States dropped its 10% import surcharge. Nixon hailed it as the most significant monetary agreement in the history of the world.

The dollar was still not convertible into gold at the new $38 price. Only the parities changed.

The Nixon Shock closes the gold window US policy

Televised address, Sunday eveningGold convertibility suspended90-day wage-price freeze; 10% import surcharge

In an address titled ‘The Challenge of Peace’, Nixon announced his New Economic Policy. He directed Treasury Secretary John Connally to suspend the convertibility of the dollar into gold for foreign official holders, froze wages and prices for 90 days and imposed a 10% surcharge on dutiable imports. He said the aim was to create jobs, stop the rise in the cost of living and ‘protect the dollar from the attacks of international money speculators’.

The speech was popular at home and the stock market rose the next day. Abroad, it was a shock: allies had not been consulted, and the anchor of the postwar monetary system was gone.

Nixon took his economic team to Camp David in secret to settle a package. Arthur Burns argued against closing the gold window, fearing market chaos; Connally pressed for bold action. Unemployment was about 6% and inflation was running above 5%, with an election due in 1972.

The German mark floats Crisis

Huge dollar inflows into West GermanyMark and Dutch guilder floatSwiss franc and Austrian schilling revalued

A wave of money fleeing the dollar forced the Bundesbank to stop buying dollars. West Germany and the Netherlands let their currencies float, and Switzerland and Austria revalued. It was an early sign that the parity system could not hold, and pressure moved to the US gold stock over the summer.

The IMF made its first allocation of Special Drawing Rights to member countries, to increase global reserves without relying on more US deficits or more gold. The idea was a direct response to the Triffin dilemma, but it came too late, and at too small a scale, to rescue the gold-dollar link.

Charles de Gaulle used a press conference to criticise the dollar’s special role and call for an international system based on gold. France stepped up conversions of its dollar reserves into gold. Valéry Giscard d’Estaing, his finance minister, had earlier described the dollar’s role as an ‘exorbitant privilege’.

The London Gold Pool is formed Gold

Eight central banksUS provides half the goldAim: hold London gold near $35

The central banks of the United States, Britain, West Germany, France, Italy, Switzerland, the Netherlands and Belgium pooled gold to calm the London market. From March 1961 the US Treasury’s Exchange Stabilization Fund had also begun intervening in currency markets, and in March 1962 the Fed opened its first swap line, with the Bank of France.

Gold jumps to $40 in London Crisis

First big break above $35Triffin’s warning publishedForeign dollar claims overtake US gold

Ahead of the US presidential election, the London gold price briefly hit $40 an ounce. The same year Robert Triffin published Gold and the Dollar Crisis, warning that a system relying on growing US deficits to supply world reserves would eventually undermine confidence in the dollar’s gold value. By 1961 dollar claims on the United States exceeded its gold stock.

Bretton Woods begins working as designed Currencies

Western European currencies become convertibleFixed parities now fully testedDollars start piling up abroad

Major European countries made their currencies convertible for current-account transactions. The Federal Reserve’s historians date the fully operational Bretton Woods system from 1958, which means it worked as planned for barely 13 years.

Delegates from 44 Allied nations spent three weeks designing the postwar monetary system. The American plan, led by Treasury official Harry Dexter White, prevailed over John Maynard Keynes’s more ambitious British design for an international clearing union. Currencies would hold fixed but adjustable values against the dollar, and the dollar would be convertible into gold at $35 an ounce for foreign official holders.

After the war the United States held roughly three-quarters of the world’s official gold reserves, which made the dollar the natural anchor.

The Gold Reserve Act transferred the Federal Reserve’s gold to the Treasury and let Roosevelt revalue it; he fixed the price at $35 an ounce, up from $20.67, effectively devaluing the dollar by about 41%. The $35 price became the anchor of the Bretton Woods system a decade later and lasted until 1971.

Pick a sum in dollars. How much gold would it have bought?

Until 15 August 1971 a foreign central bank could hand the US Treasury dollars and receive gold at $35 an ounce. Compare that with the $42.22 price still used in the Treasury’s accounts and gold’s market price on 13 October 2026 (about $4,182). Illustrative only.

Why Did the Bretton Woods System Collapse?

No single event broke the system. Five pressures built up over a decade.

Structure

Too many dollars, too little gold

World trade needed ever more dollar reserves, but each extra dollar abroad was another potential claim on a fixed stock of US gold. By about 1961 the claims exceeded the gold.

Inflation

A weaker dollar

US inflation rose from under 2% in early 1965 to about 6% by the end of 1969, as spending on the Vietnam War and domestic programmes grew. A fixed $35 gold price looked ever less realistic.

Politics

Domestic goals came first

Defending the peg would have meant higher interest rates and slower growth. With unemployment near 6% and an election in 1972, Washington chose growth.

Markets

Capital moved faster than parities

Speculators could move huge sums into marks, francs and gold in days. Fixed rates gave them one-way bets, as Germany found in May 1971.

Diplomacy

Allies resented the privilege

France and others objected that the United States could finance deficits by printing the world’s reserve currency, and converted dollars into gold.

Design

Repairs came too late

The Gold Pool, swap lines, the two-tier market and SDRs each bought time. None solved the basic imbalance, and the Smithsonian deal only reset the numbers.

Did the US Dollar Lose Its Global Dominance?

No. But in 2026 the debate over its role, and over gold, is louder than at any time since the 1970s.

Ending gold convertibility did not end the dollar’s role as the world’s leading reserve currency. It kept its place thanks to the size of the US economy, the depth of the Treasury market, its use in trade invoicing and commodity pricing, and the lack of an equally liquid alternative. What changed was the basis of confidence: from a claim on gold to trust in US institutions and markets.

That trust is now being tested in a different way. The dollar’s share of allocated foreign exchange reserves has drifted down from about 71% around 1999 to 56.70% in mid-2026. Central banks have bought around 1,000 tonnes of gold a year, and the ECB estimates gold made up about 27% of their reserves at the end of 2025, ahead of US Treasuries. Gold itself hit a record above $5,500 in January 2026. Yet no rival has replaced the dollar, and the euro, the second-largest reserve currency, holds about a fifth of reserves.

What the Collapse Meant for India

India sent a delegation to Bretton Woods in 1944 and became a founding member of the IMF and the World Bank. Under the system the rupee was tied to sterling, and through it to the dollar, at Rs 4.76 per dollar. In June 1966, under pressure from war, drought and aid donors, India devalued the rupee by 36.5% to Rs 7.50 per dollar.

When Nixon closed the gold window, India briefly pegged the rupee to the dollar, then returned to a sterling peg after the Smithsonian Agreement in December 1971. As sterling itself floated and weakened, India switched in September 1975 to a peg against an undisclosed basket of currencies, the start of a managed regime that eventually gave way to market-determined rates in 1993. The rupee’s long fall against the dollar began in this period.

People Also Ask

Why is it called Bretton Woods?
The 1944 conference was held at the Mount Washington Hotel in Bretton Woods, New Hampshire, a resort in the White Mountains, from 1 to 22 July 1944.
Who ended the Bretton Woods system?
Richard Nixon suspended dollar-gold convertibility on 15 August 1971. The fixed-rate system it supported broke down in February to March 1973, and the IMF formally accepted floating in 1976 to 1978.
What replaced the Bretton Woods system?
A system of floating and managed exchange rates, recognised by the IMF’s Second Amendment in 1978. Countries may float, peg or manage their currencies, but none is formally tied to gold.
How much gold did the US have in 1971?
Far less than foreign official dollar claims. The Fed History account notes that those claims had exceeded the US gold stock since about 1961, which was the core weakness of the system.
Was the Nixon Shock good or bad?
Opinions differ. It freed US monetary policy and ended an unsustainable peg, but it was followed by a decade of high inflation, oil shocks and volatile currencies.

Frequently Asked Questions

What was the Bretton Woods system?
It was the international monetary framework agreed by 44 Allied nations at Bretton Woods, New Hampshire, in July 1944. Member currencies had fixed but adjustable par values against the US dollar, and the United States promised foreign governments and central banks that it would convert their dollars into gold at $35 an ounce. It also created the IMF and the World Bank.
When did the Bretton Woods system collapse?
In two stages. On 15 August 1971 President Richard Nixon suspended the conversion of foreign official dollars into gold, removing the system’s anchor. Governments then tried to rebuild fixed rates in the Smithsonian Agreement of December 1971, but that broke down in February and March 1973, when the major currencies began to float against the dollar.
Why did Nixon end the gold link in 1971?
Foreign official claims on US dollars had exceeded the US gold stock since the early 1960s, US inflation had risen to around 6% by 1969 and the dollar was under speculative attack in 1971. West Germany floated its currency in May. Facing the risk that foreign central banks would demand more gold than the United States could deliver, Nixon closed the gold window.
What was the Nixon Shock?
It is the name given to the New Economic Policy that Nixon announced in a televised address on the evening of Sunday 15 August 1971, after a weekend of meetings at Camp David. It suspended dollar-gold convertibility for foreign official holders, imposed a 90-day freeze on wages and prices, and added a 10% surcharge on dutiable imports.
What does ‘closing the gold window’ mean?
The ‘gold window’ was the US Treasury’s commitment to sell gold to foreign governments and central banks at $35 an ounce in exchange for their dollars. ‘Closing’ it meant the Treasury would no longer honour those requests. Private individuals had not been able to exchange dollars for gold in the United States since 1933.
Was the US dollar backed by gold before 1971?
Only partly. Americans lost the right to redeem dollars for gold in 1933, and the Gold Reserve Act of January 1934 set the official price at $35 an ounce. Under Bretton Woods, the remaining link was the promise to convert dollars held by foreign official institutions into gold. That promise ended in August 1971.
What was the Smithsonian Agreement?
An accord reached by the Group of Ten finance ministers and central bankers at the Smithsonian Institution in Washington on 18 December 1971. It raised the official gold price from $35 to $38 an ounce, revalued several currencies against the dollar, widened the permitted trading bands from 1% to 2.25% either side of the new central rates, and ended the US import surcharge.
Why did the Smithsonian Agreement fail?
It changed exchange rates without changing the forces behind the pressure. US inflation and monetary policy, large capital flows and doubts about the dollar continued. Gold rose to about $60 an ounce on the free market by mid-1972 and about $90 by early 1973, sterling floated in June 1972 and a fresh dollar crisis in early 1973 ended the fixed rates.
When did currencies start floating?
Some floated earlier, including Canada in 1970, the German mark in May 1971 and sterling in June 1972. The general move came after the dollar was devalued again on 12 February 1973. In March 1973 six European Community countries agreed a joint float against the dollar and, when markets reopened on 19 March, the major currencies were floating.
What was the second dollar devaluation in 1973?
On 12 February 1973, with European and Japanese exchange markets closed, the United States devalued the dollar by 10%, raising the official gold price from $38 to $42.22 an ounce. The new rate was formally enacted later that year. It lasted about a month before the general float.
What was the London Gold Pool?
An arrangement set up in November 1961 by the central banks of the United States, the United Kingdom, West Germany, France, Italy, Switzerland, the Netherlands and Belgium to keep the London gold price near $35 an ounce by buying and selling together. France withdrew in 1967, and the Pool collapsed in March 1968 after heavy private buying.
What was the two-tier gold market?
After the Gold Pool collapsed, central banks agreed in March 1968 to separate gold into two markets. Official transactions between monetary authorities continued at $35 an ounce, while the private market price was left free to move. It eased the drain on official reserves but showed how strained the $35 peg had become.
What is the Triffin dilemma?
It is the problem identified by the economist Robert Triffin in his 1960 book Gold and the Dollar Crisis. The world needed a growing supply of dollars for trade and reserves, which required the United States to run deficits. But the more dollars piled up abroad, the less credible the promise to convert them into a limited stock of gold at $35 an ounce.
What are Special Drawing Rights (SDRs)?
SDRs are an international reserve asset created by the IMF to supplement member countries’ reserves. They were authorised by an amendment to the IMF’s Articles in 1969 and first allocated on 1 January 1970. They were meant to ease the shortage of reserves without relying on more US dollars or gold, but did not save the gold-dollar link.
What was the Jamaica Agreement?
At a meeting of the IMF’s Interim Committee in Kingston, Jamaica, in January 1976, members agreed to amend the IMF’s Articles to let countries choose their own exchange-rate arrangements, including floating, and to remove gold’s official role in the system. The Second Amendment took effect on 1 April 1978.
When could Americans own gold again?
From 31 December 1974, when a law passed earlier that year lifted the restrictions on private gold ownership that had been in place since 1933.
Who was at Camp David in August 1971?
Nixon and about 15 advisers. They included Treasury Secretary John Connally, Federal Reserve Chairman Arthur Burns, Paul Volcker, then Treasury Under Secretary for Monetary Affairs, and George Shultz, director of the Office of Management and Budget. Secretary of State William Rogers and National Security Adviser Henry Kissinger were not there.
What did John Connally mean by ‘our currency, your problem’?
Treasury Secretary John Connally is widely reported to have told European finance ministers in 1971 that the dollar was ‘our currency, but your problem’. The phrase captured the US stance after the Nixon Shock: other countries holding dollars would have to bear the adjustment, and Washington would use the import surcharge as leverage.
Did the dollar lose its global role after Bretton Woods?
No. The dollar stayed the main reserve, trade-invoicing and funding currency, backed by the size of the US economy and the depth of its Treasury market. Its share of global foreign exchange reserves has slipped from about 71% around 1999 to 56.70% in the second quarter of 2026, according to IMF data released on 30 September 2026.
Has gold overtaken US Treasuries in central bank reserves?
According to the European Central Bank’s June 2026 report on the international role of the euro, gold made up about 27% of global central bank reserves at the end of 2025, against about 22% for US Treasuries. Part of the shift reflects the sharp rise in the gold price, not only new buying.
What is gold worth today compared with $35 in 1971?
Gold traded at about $4,182 an ounce on 13 October 2026, roughly 119 times the old $35 official price. It set a record above $5,500 in late January 2026. The US Treasury still values its gold at the statutory $42.22 an ounce on its books.
Could the US return to a gold standard?
It is very unlikely. A fixed gold price would tie monetary policy to the supply of one metal and would require enormous gold reserves at today’s prices. Most economists see the post-1973 system of floating rates and independent central banks as more flexible, despite its volatility.
What does Bretton Woods mean for India?
India was one of the 44 countries at Bretton Woods and a founding IMF member. The rupee was then linked to sterling. India devalued it by 36.5% in June 1966, from Rs 4.76 to Rs 7.50 per dollar. After the Nixon Shock it briefly pegged to the dollar, returned to sterling in December 1971 and moved to a basket of currencies in September 1975.

The Day the Dollar Changed Its Foundations

The collapse of Bretton Woods was not simply the end of a gold peg. It was the breakdown of a monetary bargain that linked the world’s leading reserve currency to gold and every other major currency to the dollar. Nixon’s address on 15 August 1971 began the decisive break; the failure of the Smithsonian Agreement showed the old framework could not survive unchanged; and by March 1973 the world had entered the era of floating rates.

Fifty-five years later the dollar is still at the centre of global finance, but without any promise that it can be exchanged for gold. Gold, freed from its $35 price, now trades above $4,000 and is again one of the biggest assets in central bank vaults.
