Gold Standard

A gold standard is a monetary arrangement in which the unit of account is defined as a fixed weight of gold and the issuing authority stands ready to exchange its currency for gold at that rate. Three things follow mechanically. The currency has a legally fixed gold price. Currencies on the same standard therefore have fixed rates against one another, because each is fixed to the same metal. And monetary policy is subordinated to defending the peg, since the authority cannot issue more currency than its reserves and its convertibility promise will support.

The phrase is loose, and a page that treats "the gold standard" as one system will mislead. What the United States had before 1933 was a domestic standard, in which the government converted paper currency into gold coin whenever citizens asked. What it had between 1944 and 1971 was different: under Bretton Woods other currencies were fixed to the dollar and only the dollar was fixed to gold, so convertibility ran to foreign monetary authorities rather than to the public. Both are called gold standards, and the difference between them is most of the story of how the arrangement ended.

The American sequence, which is the clearest way to see the mechanism. The United States was on a de facto gold standard from the 1830s and a de jure one from 1900, at a parity of $20.67 per ounce of pure gold. The Federal Reserve Act of 1913 built the standard into the new central bank: the law "required the Federal Reserve to hold gold equal to 40 percent of the value of the currency it issued" and to convert those dollars into gold at that price. The 40 percent cover requirement is the constraint that matters. It meant the quantity of currency was capped by the stock of gold, and it meant a gold outflow forced monetary tightening at exactly the moment the domestic economy might need the opposite.

That is what broke in 1933. Gold outflows continued through the banking crisis; the Emergency Banking Act in March gave the president control of gold movements and the Treasury power to compel surrender of gold coins and certificates. On April 20, 1933, a presidential proclamation "formally suspended the gold standard," prohibiting gold exports and barring the Treasury and financial institutions from converting currency and deposits into gold coins and ingots. In May the Thomas amendment to the Agricultural Relief Act gave the president power to cut the dollar's gold content by as much as 50 percent, and to back the dollar with silver instead of or alongside gold. On June 5 a congressional resolution abrogated gold clauses in all contracts, government and private, clauses that had guaranteed repayment in gold or its monetary equivalent at the 1900 value; the Supreme Court upheld those actions. From October 1933 the government ran a gold purchase plan through the Reconstruction Finance Corporation, buying gold at rising prices in what Federal Reserve History calls "the deliberate devaluation of the dollar."

The Gold Reserve Act, signed January 30, 1934, finished the job. Section 2 transferred ownership of all monetary gold in the United States, including the Federal Reserve's, to the Treasury, with holders receiving currency at $35 per ounce; that rate "reduced the gold value of the dollar to 59 percent of the value set" in 1900. Sections 5 and 6 prohibited the Treasury and financial institutions from redeeming dollars for gold, which Federal Reserve History describes as "inverting the system that had prevailed in the United States since the nineteenth century": the government now converted gold into dollars rather than dollars into gold, whether or not the holder wanted the exchange. Sections 3, 4 and 11 restricted private gold to bars, forbade coin holdings, permitted industrial uses such as dental appliances, jewelry and electronics, and left items under fifteen ounces freely tradable while heavier transactions required licenses. Section 10 created a $2 billion stabilization fund from the government's profit on raising the gold price, the origin of the Exchange Stabilization Fund. Section 12 authorized the president to set the dollar's gold value by proclamation, which he did the next day.

The international arrangement, and how it ended. Forty-four countries met at Bretton Woods, New Hampshire, in 1944 and agreed to keep their currencies fixed, "but adjustable in exceptional situations," to the dollar, with the dollar fixed to gold. From 1958, when the system became operational, countries settled international balances in dollars and dollars were convertible to gold at $35 an ounce. The United States held about three-quarters of the world's official gold reserves, so the promise looked easy to keep. It stopped looking easy in the 1960s, as European and Japanese exports grew and dollar claims outstanding came to exceed the American gold stock. A run in the London gold market pushed the price to $40 an ounce on October 20, 1960. Eight central banks formed the London Gold Pool on November 1, 1961 to hold the price at $35 with pooled reserves; it collapsed in March 1968 after sterling's devaluation and France's withdrawal, and the seven remaining members split the market into a two-tier system in which official gold was used only to settle debts between governments.

On the evening of August 15, 1971, President Nixon closed the gold window. Foreign governments could no longer exchange dollars for gold and, as Federal Reserve History puts it, "in effect, the international monetary system turned into a fiat one." The same announcement imposed a 90-day freeze on wages and prices and a 10 percent import surcharge. At the Smithsonian meeting that December the United States "agreed to devalue the dollar against gold by approximately 8.5 percent to $38 per ounce," with other countries revaluing upward, for a net effect of roughly a 10.7 percent average devaluation against the other key currencies. That held for barely a year. On February 12, 1973, "the United States devalued the dollar by an additional 10 percent to $42 an ounce," and within a month nearly all major currencies were floating. Bretton Woods was finished.

What survives in law, and it is not what most readers expect. Title 31 U.S.C. 5118(b) states flatly that "the United States Government may not pay out any gold coin," and provides that a lawful holder of U.S. coins and currency may present them to the Treasury for exchange, dollar for dollar, for other U.S. coins and currency "(other than gold and silver coins)." So there is no convertibility and no route back to it without new legislation. But the 1933 abrogation of gold clauses did not stay absolute. Section 5118(d)(2) provides that an obligation containing or governed by a gold clause "is discharged on payment (dollar for dollar) in United States coin or currency that is legal tender at the time of payment," and then adds: "This paragraph does not apply to an obligation issued after October 27, 1977." Gold clauses in obligations issued after that date are outside the discharge rule.

One live artifact of the old parities remains on the government's books. The Treasury still carries its gold at a statutory book value rather than a market price. Its Status Report of U.S. Government Gold Reserve for the record date July 31, 2026 shows about 261.5 million fine troy ounces at a book value of roughly $11.0 billion, which works out to $42.2222 per fine troy ounce, the parity set in 1973. The Fort Knox line alone reads 147,341,858.382 fine troy ounces at $6,221,097,412.78. Anyone reading a figure for the value of the nation's gold should check which of the two prices, statutory or market, it uses, because they differ by a very large multiple.

The mechanics of a domestic gold standard run in both directions, which is what makes it self-enforcing and also what makes it brittle. The government sets a statutory price, say $20.67 for an ounce of pure gold, and stands ready to exchange in either direction at that price. If the market price of gold rises above the official price, anyone can buy currency, redeem it for gold at the official price and sell the gold at the market price, draining official reserves until the authority tightens. If gold falls below the official price, the flow reverses. Reserves therefore act as a running scoreboard on monetary policy, and defending the peg takes priority over domestic conditions.

A hypothetical example of the 1913 cover requirement, using the statutory numbers. A reserve bank holds gold worth $400 million. A 40 percent cover requirement means it can have at most $1 billion of its notes outstanding, because $400 million is 40 percent of $1 billion. Suppose $150 million of gold then leaves the country. Reserves are $250 million, which supports at most $625 million of notes, so $375 million of currency has to be withdrawn from circulation, roughly 37.5 percent of the note issue, regardless of what the domestic economy needs. Bankers called the cushion above the requirement "free gold," and the size of that cushion determined how much of a gold outflow the system could absorb before contraction became compulsory.

Arguments made for it

• The currency's value is fixed by law rather than by policy discretion, so the authority cannot inflate away the value of money at will.
• Exchange rates between countries on the same standard are fixed, which removes currency risk from trade and cross-border lending.
• Reserve flows give an automatic and visible signal about whether policy is too loose or too tight.

Arguments against it, and what actually happened

• Monetary policy is subordinated to defending the peg, so a country losing gold has to contract during a downturn, which is the trap the 40 percent cover requirement created in the early 1930s.
• The money supply is tied to the discovery and mining of a metal rather than to the needs of the economy.
• A promise to convert is only as good as the reserves behind it, and the Bretton Woods promise failed because dollar claims outstanding grew past the American gold stock.
• Restoring convertibility would require repealing 31 U.S.C. 5118(b) and choosing a price, and the choice of price is itself a decision about redistributing wealth between debtors and creditors.
