Bretton Woods to 1971: How the US Dollar Left Gold

This guide reconstructs how a monetary system built in the closing months of World War II unwound over three decades, and why the design of the system carried a structural flaw that Robert Triffin identified more than a decade before the collapse. It is a piece of financial history, not a prediction about what happens next.

What the 1944 conference actually built

July 1944 · Bretton Woods, New Hampshire

In July 1944, delegations from 44 nations gathered at the Mount Washington Hotel in Bretton Woods, New Hampshire, for what was officially called the United Nations Monetary and Financial Conference. Their brief: rebuild an orderly international monetary system before the war ended, so postwar trade could restart without the competitive devaluations and beggar-thy-neighbor tariffs that scarred the 1930s.

Two institutions came out of that meeting: the International Monetary Fund (IMF) and the International Bank for Reconstruction and Development (IBRD), later grouped under the World Bank name. The U.S. Congress ratified American participation through the Bretton Woods Agreements Act in July 1945, and both bodies opened for business later that year.

The exchange system had two moving parts:

• The U.S. dollar was pegged to gold at $35 per troy ounce. Foreign governments and central banks that held dollars could exchange them for gold at that rate, on demand, at the U.S. Treasury.
• Other national currencies were pegged to the dollar at declared par values, with a narrow 1% band around par. Devaluations beyond a set threshold required IMF approval.

Historians describe this as the gold-exchange standard, or the gold-dollar standard. It was not a full domestic gold standard: American households had lost the right to redeem paper dollars for gold coin in 1933, under Executive Order 6102 (see the confiscation history). Only foreign monetary authorities retained the redemption right after 1944. The rest of the world traded gold on private markets, at prices that could and did diverge from the official $35 peg.

The Triffin dilemma: a math problem the system could not solve

Belgian-American economist Robert Triffin, who had worked at the IMF and taught at Yale, spelled out the trap in his 1960 book Gold and the Dollar Crisis: The Future of Convertibility and in testimony before the Joint Economic Committee of the U.S. Congress. His argument was straightforward and hard to refute.

The dollar was the world’s reserve currency. Foreign central banks needed dollars to settle trade, hold as reserves, and back their own currencies. To supply those dollars, the United States had to send more dollars abroad than it received back. That required persistent balance-of-payments deficits.

The more dollars that piled up in foreign vaults, however, the larger the theoretical claim on U.S. gold at $35 an ounce. Confidence in the peg depended on the United States not running large deficits, which was the exact opposite of what supplying the world with reserves required.

The numbers confirmed his forecast. By 1959, the value of U.S. dollars held abroad had crossed above the market value of U.S. gold reserves at $35 an ounce. Federal Reserve historical data indicates that by 1966, foreign central banks held roughly $14 billion in dollar reserves against U.S. gold holdings valued at about $13.2 billion. Only around $3.2 billion of that gold was legally available to cover foreign claims, since a portion was held domestically as backing for Federal Reserve notes and other statutory purposes.

Anyone doing the arithmetic could see the peg was underfunded. What kept it alive for another decade was diplomacy, political pressure on foreign governments to not redeem, and the belief that the United States would eventually correct its deficits. Neither happened.

The 1960s strain: the London Gold Pool

November 1961 to March 1968

Free-market gold trading did not stop under Bretton Woods. Bullion changed hands every day on the London bullion market, and if private demand pushed the London price above $35, arbitrage would drain U.S. reserves: foreign central banks could buy cheap gold from Washington at the official price and sell it dear in London, pocketing the difference.

To prevent that pressure, eight central banks formed the London Gold Pool on November 1, 1961. Members pooled bullion reserves and coordinated sales to keep the London price locked near $35. The contributions:

For a few years the pool held. Then the underlying pressures caught up. Rising U.S. deficits financing the Vietnam War and Great Society programs, combined with growing private demand for gold as prices in other assets rose, forced the pool to sell more metal each year. Between 1961 and 1968 the pool’s eight members sold roughly 3,000 tonnes of gold trying to hold the $35 line.

France withdrew in June 1967, and Charles de Gaulle publicly ordered gold reserves transferred from the New York Federal Reserve to Paris, a gesture the market read exactly the way it was meant. The British pound was devalued in November 1967. Runs on the pool intensified through early 1968. On March 14, 1968, U.S. and U.K. authorities closed the London gold market for two weeks. When it reopened, the pool was over.

What replaced it was a two-tier system: the official $35 price remained for transactions between central banks, while private markets found their own price. Within months, the free-market price traded well above $35. The peg still existed on paper. The world had stopped believing in it.

Timeline: how convertibility unwound

August 15, 1971: what Nixon actually announced

On Sunday evening, August 15, 1971, President Richard Nixon delivered a televised address from the Oval Office. American financial markets were closed for the weekend, which gave the White House the entire following week to observe reactions before Wall Street opened.

The speech introduced what the administration called the “New Economic Policy.” It contained three main measures:

1. Suspension of dollar-gold convertibility. Foreign central banks could no longer exchange dollars for gold at the U.S. Treasury. Nixon framed the move as temporary. It has never been reversed.
2. A 90-day wage and price freeze, imposed by Executive Order 11615 to fight domestic inflation running at roughly 5.8% and unemployment at 6.1%.
3. A 10% surcharge on imports, designed to force trading partners to appreciate their currencies against the dollar and reduce the trade deficit.

The televised justification leaned on national interest and monetary stability. “We must protect the position of the American dollar as a pillar of monetary stability around the world,” Nixon said. In practical terms, however, the announcement acknowledged what markets already knew: the United States did not have the gold to make good on the outstanding dollar claims at $35 an ounce, and Washington was no longer willing to lose more metal defending a peg the world had priced out.

Federal Reserve historical records indicate U.S. gold reserves had fallen from a peak above 20,000 tonnes in the 1940s to roughly 8,000 to 9,000 tonnes by mid-1971. Cross-linked to the outstanding foreign dollar claims of the period, the ratio was no longer defensible.

The morning after the speech, European exchanges remained closed. When trading resumed, currencies immediately began floating higher against the dollar. Free-market gold jumped above $40 an ounce within weeks, and never returned to $35.

The Smithsonian Agreement and the drift to floating rates

Nixon presented the August 1971 move as temporary in part because U.S. officials still believed a repaired fixed-rate system was possible. The Smithsonian Agreement, signed on December 18, 1971, by the Group of Ten (Belgium, Canada, France, Germany, Italy, Japan, the Netherlands, Sweden, the United Kingdom, and the United States) attempted that repair.

Its main terms:

• Gold was officially revalued from $35 to $38 per ounce, a 7.9% devaluation of the dollar.
• Other major currencies appreciated against the dollar: the Japanese yen by 16.9%, the Deutsche mark by 13.6%, the French franc and British pound by 8.6% each, the Italian lira by 7.5%.
• Currency fluctuation bands were widened from 1% to 2.25% around par.
• Convertibility of the dollar to gold was not restored.

Nixon publicly called it “the most significant monetary agreement in the history of the world.” It lasted 14 months. Persistent U.S. inflation and continued balance-of-payments deficits meant the new peg quickly came under the same pressure as the old one. In February 1973 the dollar was devalued again, to a statutory $42.22 per ounce (a number that still appears in U.S. Treasury accounting to this day, though it has no operational meaning).

On February 14, 1973, Japan and OEEC member countries let their currencies float against the dollar. European exchange markets closed and reopened in March 1973 with free-floating rates. The fixed-rate system was finished in practice. The Jamaica Accords of 1976 made it official at the IMF level, removing gold as the reference asset of the international monetary system.

What happened to inflation, the dollar, and gold after 1971

Three data series capture the transition. Consumer prices, the dollar’s exchange value, and the price of gold all moved in ways the pre-1971 system had been designed to prevent.

U.S. consumer price inflation, using annual averages from the Bureau of Labor Statistics:

• 1971: 4.4%
• 1974: 11.0% (post-oil-embargo peak in the first inflation wave)
• 1979: 11.3%
• 1980: 13.5% (the modern nominal high)

The oil shocks of 1973 and 1979 did the heavy lifting on the second wave, but the underlying loss of a nominal anchor (a fixed metal peg) meant central banks now had to build credibility differently, through interest-rate policy rather than convertibility. That transition took roughly a decade.

Gold, freed from the $35 peg, rose sharply. From $35 in mid-1971, the free-market price crossed $100 in 1973, above $140 by end-1975, and reached its widely reported nominal peak on January 21, 1980, at $850 per troy ounce (London afternoon fix). Inflation-adjusted using CPI, the 1980 peak is worth roughly $3,400 in 2024 dollars. Gold then entered a two-decade bear market before restarting a bull run in the early 2000s (documented in our gold price major events guide, 1971 to 2026).

The dollar’s role changed in a subtler way. It remained (and remains) the world’s dominant reserve currency, but its status is now backed by U.S. Treasury securities, deep capital markets, and Federal Reserve credibility, rather than a fixed conversion right into metal. Foreign central banks continue to hold dollar reserves, and, in recent years, have also been accumulating gold at rates not seen since the 1960s (see our central bank gold purchases data).

What this history explains, and what it does not

The end of Bretton Woods explains why gold trades freely today, why the U.S. dollar floats against other major currencies, and why central banks manage price stability through monetary policy rather than convertibility. It also explains why the phrase “gold standard” refers to different arrangements at different points in history (the classical pre-1914 gold standard, the interwar gold-exchange standard, and the 1944 to 1971 gold-dollar standard).

What the history does not imply is a repeat. The pressures that broke Bretton Woods were specific: a fixed conversion right at $35 an ounce, an outstanding dollar overhang that grew faster than U.S. gold, and a diplomatic reluctance to raise the peg or curb deficits. None of those exact conditions exist under the current floating system. Anyone marketing gold on the premise that “Bretton Woods 2.0 is coming” is telling a story, not reporting a fact. The honest read of the history is more modest: monetary systems change when the arithmetic underneath them stops working, and the 1971 change is one example of how that plays out.
