Gold Standard 1717-1971 — History, Bretton Woods, Nixon Shock

The gold standard is a monetary system in which a currency is defined as a fixed quantity of precious metal and the banknote holder can exchange paper for a coin or an ingot at the central bank. Britain entered this regime first — in 1717 Isaac Newton, as Master of the Royal Mint, set the guinea-to-gold ratio. In 1944 Bretton Woods built a modified version: the US dollar convertible into gold at 35 dollars per ounce, other currencies pegged to the dollar. It ended on a Sunday evening, 15 August 1971, when Richard Nixon announced on television that the United States was closing the gold window. We now live in a world of fiat money, and the modern foreign exchange market is born inside it.

Newton and the British template, 1717-1870

Newton in 1717 set the guinea at 21 shillings with monetary order in mind, not a global system. Britain ended up on a de facto monometallic gold standard — silver disappeared from circulation because its market value exceeded the Mint rate. In 1821, after the Napoleonic wars, the Bank of England formally acknowledged this and convertibility of sterling into gold became law.

Most of the nineteenth-century world ran on silver or bimetallism. Germany switched to gold in 1871, after French reparations from the Franco-Prussian War. France, Belgium and Italy followed Berlin shortly after. The United States, despite the bimetallism of the 1792 Coinage Act, effectively anchored to gold with the Gold Standard Act of 1900. No international body managed any of this — gold and the London discount market handled it themselves.

The classical gold standard, 1870-1914

For forty-four years the exchange rates of major currencies were effectively fixed. Sterling cost 4.86 US dollars, the German mark held a fixed parity to sterling, the French franc the same. Goods, capital and people moved across borders with minimal friction. Long-run inflation was close to zero — prices in London in 1914 were comparable with 1870.

The mechanics demanded iron discipline. If a country imported more than it exported, gold physically leaked out. The central bank raised the policy rate, the economy cooled, prices fell, exports became competitive again, the trade balance rebuilt itself. The mechanism worked at the price of regular recessions. Currency speculation was confined to small deviations around the so-called gold points — bands set by the cost of transporting bullion between London and New York.

"The gold standard was not primarily an economic mechanism — it was a political mechanism, a guarantee that governments would not turn to the printing press in hard times." — Barry Eichengreen, Golden Fetters, 1992

The First World War and a return that did not work

August 1914 ended the classical gold standard overnight. All sides needed financing on a scale gold could not deliver. Convertibility was suspended in Britain, Germany, France and Russia. The most dramatic ending was Berlin — in November 1923 one US dollar bought 4.2 trillion marks, and a worker's monthly wage no longer covered a loaf of bread.

After the war, politicians tried to return to the pre-1914 regime. The loudest attempt was the British decision of 1925. Winston Churchill returned sterling to gold at the pre-war parity of 4.86 dollars. John Maynard Keynes immediately published The Economic Consequences of Mr. Churchill, arguing the pound was overvalued by some ten percent. He was right — British exports suffered, unemployment rose, and in September 1931 the Bank of England left gold again, sterling losing twenty-five percent in weeks. The United States held on longer, but in 1933 Franklin D. Roosevelt confiscated private gold under Executive Order 6102 and devalued the dollar from 20.67 to 35 dollars per ounce. When governments face a choice between gold discipline and protecting the economy, they pick the latter.

Bretton Woods, 1944-1971

In July 1944, with the war still on, delegations from forty-four countries gathered at the Mount Washington Hotel in Bretton Woods, New Hampshire. The principal architects were Harry Dexter White (US) and John Maynard Keynes (UK). White's plan won — the United States held about two-thirds of the world's official gold reserves.

The dollar was the only currency directly convertible into gold, at 35 dollars per ounce (in force since 1934). Every other currency was pegged to the dollar with permitted deviation of plus or minus one percent. The International Monetary Fund and the World Bank were created. A trader from today's Forex would see no room for speculation — rates moved by fractions of a percent and central banks actively defended parities. For twenty-seven years the system worked.

The Triffin dilemma and the slow unravelling

Robert Triffin, a Belgian-born Yale economist, testified before Congress in 1960 with the thesis now known by his name. If the dollar is the world's reserve currency, the United States must print more than its domestic economy requires, because the rest of the world needs the supply. But the more dollars circulate outside the United States, the lower the chance American gold reserves can cover demand for conversion. Triffin predicted the collapse of Bretton Woods a decade before it happened.

Through the 1960s dollars accumulated abroad. The United States financed the Vietnam War, Lyndon Johnson's Great Society and a growing trade deficit. Physical gold flowed from American vaults into European ones. In 1949 the United States held about 21,800 tonnes — over two-thirds of the world's official reserves. By summer 1971 less than nine thousand tonnes remained. American inflation crossed five percent in 1971. Nixon's advisers, led by Paul Volcker and John Connally, began preparing an exit plan.

Sunday, 15 August 1971: the Nixon Shock

That weekend Nixon summoned around a dozen advisers to Camp David. Talks lasted three days. On Sunday evening, at nine Eastern Time, the president went on television with a fifteen-minute address titled the New Economic Policy. Three decisions mattered: suspension of dollar convertibility into gold, a ten percent temporary tariff on imports, a ninety-day freeze on prices and wages. The press christened it the Nixon Shock — planned as temporary, it turned out to be permanent.

An attempt to rescue the old system was the Smithsonian Agreement of December 1971 — the dollar was devalued by roughly eight percent and exchange rate bands widened to plus or minus 2.25 percent. Nixon called it the most significant monetary agreement in history. It held nineteen months. By March 1973 the major currencies began to float freely. The year 1973 is the birth year of the modern Forex market. Paul Volcker, who coordinated the operation, later called it the most important monetary event of the postwar world.

Why we are not going back

The argument for returning to gold surfaces regularly during high-inflation periods. No serious country prepares such an operation. Two reasons are decisive. First, physical supply. Every bar ever mined — World Gold Council estimates around 213,000 tonnes — at a 2024 price above 2,400 dollars per ounce values global gold supply at roughly 17 trillion dollars. Daily Forex turnover in 2022, per BIS, came to 7.5 trillion. The entire world stock of bullion covers two days of currency trading.

Second, monetary discipline. Under a gold standard a central bank cannot print money to help the economy through a recession or rescue banks in a crisis. The Great Depression of 1929-1933 showed where rigid discipline leads when demand collapses — deflation, mass unemployment, political destabilisation. Modern fiscal states do not fit such a corset.

Your next step — what this means for today's trader

Three concrete takeaways. First — every currency on your screen is fiat money. Its value depends on confidence in the central bank and the fiscal discipline of the government, not on metal in a vault. The decisions of the Fed, the ECB and the Bank of Japan on rates and money creation now play the role gold reserves once played. The EUR/USD pair is a comparison of the credibility of two monetary institutions. More in the fundamental analysis section on ForexMechanics.com.

Second. Exchange rates are volatile because the world chose volatility. Since 1973 there is no anchor to which rates must return. Three years of dollar weakness does not mean the dollar will come back to a parity — there is no parity. The dollar fell forty percent between 1985 and 1995 and stayed there.

Third. Gold persists, but it is no longer money — it is a reserve asset and a shelter in uncertain times. Poland's central bank held around 350 tonnes in 2024. The correlation between XAU/USD and interest rates and between gold and the dollar index remains one of the most stable relationships on this market. When US real rates fall, gold rises. When the Fed leans toward cuts, DXY loses ground and the TIPS yield curve slides, you are looking at the old mechanism in a new costume. The dynamic goes back to 1971.
