What Happened in 1971? The Day the Dollar Left Gold

On the evening of 15 August 1971, President Richard Nixon told Americans he was suspending the dollar's convertibility into gold. Foreign governments could no longer exchange their dollars for US gold at $35 an ounce. The promise that had anchored the world's money since the Second World War ended that night, and it was never restored.

It matters because it removed the last outside limit on how many dollars could be created. Since then the supply of the world's main reserve currency has been a matter of policy, which is the problem bitcoin's fixed supply was built to answer.

What did Nixon do on 15 August 1971?

In a televised address he called “The Challenge of Peace”, Nixon set out three goals: more jobs, lower inflation, and protecting the dollar “from the attacks of international money speculators” (American Presidency Project). He announced three measures at once:

The gold window closed. He directed his Treasury Secretary “to suspend temporarily the convertibility of the dollar into gold or other reserve assets”. Foreign central banks could no longer turn their dollars into American gold.
A 90-day freeze on wages and prices. It was the first time the US government had imposed wage and price controls outside wartime (Federal Reserve History).
A 10% tax on imports. A temporary surcharge, meant to push America's trading partners to raise the value of their currencies (Office of the Historian).

He also proposed tax cuts and ordered a $4.7 billion cut in federal spending. The word “temporarily” did not last: dollars held abroad have never again been convertible into gold.

What was the gold window?

Towards the end of the Second World War, 44 countries met at Bretton Woods, New Hampshire, and agreed a new monetary order. Their currencies were fixed to the US dollar, and the dollar was fixed to gold. From 1958, when the system was fully working, foreign governments could take the dollars they earned to the United States and exchange them for gold at $35 an ounce (Federal Reserve History). That was the gold window.

Ordinary Americans had already lost that right. Federal Reserve notes stopped being redeemable in gold for the public in 1934 (Federal Reserve), and Britain had left the gold standard in 1931. By 1971 the gold window was the dollar's last link to gold, and only governments could use it.

Why did the US leave the gold standard?

Because it could no longer keep its promise. The system needed a growing supply of dollars abroad for trade and reserves, but every extra dollar abroad was another claim on a gold stock that barely grew. Economists call this the Triffin dilemma. By 1961, the dollars held as claims abroad already exceeded the US government's gold (Federal Reserve History).

Inflation made it worse. US prices were rising by less than 2% a year in early 1965 and by 6% by the end of 1969, which pushed still more dollars abroad. By the summer of 1971, speculators were selling dollars and central banks were converting them into US gold. Federal Reserve History puts the paradox plainly: “Without additional dollar reserves, the system was unworkable”. With them, it was unstable.

How the Bretton Woods system ended, 1971–1978

Closing the gold window did not end fixed exchange rates at once. Burying them took until 1978:

18 December 1971: the Smithsonian Agreement. The Group of Ten industrial economies agreed new fixed rates around a devalued dollar, with gold at $38 an ounce. Nixon called it “the most significant monetary agreement in the history of the world” (FRUS). The import surcharge was lifted on 20 December.
12 February 1973: a second devaluation, of 10%, took the official price to $42.22 an ounce (FRUS; Public Law 93-110).
March 1973: the major currencies began to float against the dollar, and the fixed rates of Bretton Woods were abandoned (Office of the Historian).
January 1976: meeting in Jamaica, the IMF's Interim Committee agreed new rules for a world of floating currencies.
1 April 1978: the new rules took effect. Floating exchange rates became legal, and gold's official role in the system ended (IMF).

One relic survives. US law still values the gold behind the Treasury's gold certificates at $42.22 an ounce, the price of 1973 (31 U.S.C. § 5117). It is a book value, not a price at which anyone can buy or sell.

What changed after 1971?

Nixon assured Americans who bought American goods that “your dollar will be worth just as much tomorrow as it is today” (American Presidency Project). The record since, in the government's own figures:

Prices: US consumer prices rose 8.2 times between August 1971 and August 2026 (BLS). A dollar from August 1971 buys about 12 cents' worth today: 87.8% of its purchasing power is gone.
Money: the broad money supply, M2, grew from $685.5 billion in August 1971 to $23.3 trillion in August 2026, 34 times as much (Federal Reserve, H.6).
Debt: federal debt was $398.1 billion at the end of fiscal 1971 and $40.2 trillion at the end of fiscal 2026, about 101 times as much (US Treasury). Measured against the economy, it rose from 35% of GDP in the third quarter of 1971 to 123% in the first quarter of 2026 (FRED).

Not all of that growth is inflation in waiting: the economy grew too, and a bigger economy uses more money. But since the gold window closed, the supply of dollars and the debts written in them have grown far faster than prices, and prices have risen in every decade.

Did 1971 cause everything in those charts?

Not on its own. A popular website, WTF Happened in 1971?, collects dozens of charts that seem to change course around that year: wages against productivity, house prices, debt, inequality, even incarceration. It implies the end of the gold link was the cause. The charts are a good prompt and a weak proof, because most of those trends have several causes.

Inflation, for one, was already rising before Nixon spoke, and the freeze only held it back for a while: prices rose again because monetary momentum had already built up (Federal Reserve History). Then came the Arab oil embargo of 1973–74, when the price of a barrel “first doubled, then quadrupled” (Office of the Historian). The same source traces the high inflation and stagnation that followed to a complex set of factors, the floating dollar among them.

Add the growth of world trade, new technology, and changes in tax and regulation, and no single cause can claim the charts. Economists still argue about the weights.

What 1971 did change is the rule underneath. Before it, the United States had to hold enough gold to honour its promise, and that limited how many dollars it could create. After it, no outside limit remained. The supply of dollars became purely a matter of policy, and the figures above show what that policy added up to.

The case for ending the gold link

Defenders of the decision make three points, and they deserve a hearing:

It was unavoidable. The United States did not have the gold to redeem the dollars held abroad. Keeping the window open invited a run.
Floating rates absorb shocks. Exchange rates can move when economies diverge, instead of forcing the adjustment through lost jobs.
Central banks gained room to act. Without a gold constraint, a central bank can lend freely in a panic and cushion a recession.

The cost of that flexibility is that nothing outside the system now limits it. The Federal Reserve aims for inflation of 2% a year (its longer-run goals), a pace at which money loses half its value in about 35 years. The anchor that was gold is now a promise by a committee.

Why 1971 matters for bitcoin

Bitcoin was designed for a world without a gold window. It is not backed by gold or by anything else, and no one can redeem it. What it restores is the property 1971 removed from the dollar: a limit on supply that no official can suspend, “temporarily” or otherwise.

The limit is written into the software every full node runs: new coins are issued on a fixed schedule, and the total can never exceed 21 million. Anyone can check the rule, and changing it would take the people running the network to adopt different software. It is a different kind of anchor from gold, but it answers the same question: who decides how much money there is?

Questions people ask

Who ended the gold standard?

It ended in stages. Britain left gold in 1931. The United States stopped redeeming its notes in gold for its own citizens in 1934, under President Roosevelt. President Nixon closed the gold window for foreign governments in 1971, and the IMF's rules ended gold's official role in 1978.

What was the Nixon shock?

The name given to the measures Nixon announced on 15 August 1971: closing the gold window, a 90-day freeze on wages and prices, and a 10% surcharge on imports. It shocked many of America's allies, who saw it as the United States acting alone.

Is the US dollar still backed by gold?

No. The Federal Reserve says its notes “are not redeemable in gold, silver, or any other commodity” (Federal Reserve). The Treasury still owns gold, valued in law at $42.22 an ounce, but no holder of dollars has a claim on it.

What else happened in 1971?

In Britain, 1971 was also the year of Decimal Day. On 15 February 1971, the pound stopped being 240 pence and became 100 new pence (Royal Mint Museum). Decimalisation changed how money was counted. The gold window changed what money was.
