In brief

The United States did not leave one gold standard in one clean step. Two different breaks are commonly compressed into a single story:

  1. 1933–34: the Roosevelt administration ended ordinary domestic gold convertibility, restricted monetary gold ownership and movement, transferred monetary gold to the Treasury, and changed the statutory price of gold from $20.67 to $35 per ounce. Raising the dollar price of gold reduced the dollar’s gold value by about 41 percent.
  2. 1971–73: under Bretton Woods, foreign monetary authorities could still convert official dollar balances into gold at $35 per ounce. President Richard Nixon suspended that convertibility on August 15, 1971. A negotiated exchange-rate realignment followed, then the fixed-rate system broke down and major currencies moved toward floating rates in 1973.

The 1971 decision did not by itself create all subsequent dollar depreciation or 1970s inflation. U.S. inflation, balance-of-payments deficits, and pressure on gold reserves were already destabilizing Bretton Woods. Ending convertibility removed the promise that constrained the system; exchange rates and monetary policy then adjusted through a wider set of forces.

Four terms that should not be mixed together

Term Meaning Example
Devaluation An official reduction in a currency’s value under a fixed-rate system Raising the official dollar price of gold in 1934
Depreciation A market-driven decline against another currency under floating rates The dollar falls against the yen in foreign-exchange markets
Inflation A sustained rise in the general domestic price level Consumer prices rise across a broad basket
Gold-price increase More dollars are required to buy gold May reflect inflation, real rates, risk, supply and demand, or currency conditions

These can occur together, but they are not synonyms. The dollar can appreciate against another currency during U.S. inflation if conditions are worse abroad. Gold can rise or fall for reasons beyond the monetary base. A fixed official gold price is also different from a freely traded market price.

The first break: 1933–34

The United States had operated on a de facto gold standard since the nineteenth century and adopted a formal statutory standard in 1900. The Federal Reserve framework required gold backing for currency and conversion at $20.67 per ounce of pure gold. Federal Reserve History: Roosevelt’s Gold Program

During the Great Depression, banks failed, depositors demanded currency and gold, prices fell, and debt burdens intensified. Defending gold convertibility conflicted with expanding money and credit to stabilize banks and reflate the economy. The mechanics are covered in The Great Depression and How Deflation Became Possible.

In March 1933, Roosevelt declared a national bank holiday. The Emergency Banking Act expanded presidential authority over banking and gold transactions and helped take Federal Reserve notes out of ordinary gold convertibility. Emergency Banking Act of 1933

The policy developed in stages:

Date Policy Effect
March 1933 National bank holiday and Emergency Banking Act Stabilized the banking system and expanded control over gold and foreign exchange
Spring 1933 Restrictions on monetary gold payments, exports, and hoarding Broke ordinary domestic convertibility and reduced gold outflows
Late 1933 Government gold-purchase program Deliberately raised gold’s dollar price and lowered the dollar’s gold and foreign-exchange value
January 1934 Gold Reserve Act Transferred monetary gold to the Treasury and barred dollar redemption into gold
1934 parity Gold price fixed at $35 per ounce Formalized a large devaluation from the old $20.67 parity

The arithmetic is easy to misstate. Gold’s official dollar price rose by roughly 69 percent, from $20.67 to $35. But the dollar’s gold content moved in the inverse direction: a dollar bought about 41 percent less gold. Both statements describe the same change from different denominators.

The policy goal was reflation. The administration wanted commodity and other prices to rise from Depression lows, reducing real debt burdens and supporting banks, businesses, and exports. Federal Reserve History notes that later economic research generally connects departure from gold constraints and reflation with earlier recovery across industrial economies, while also documenting the policy’s intense contemporary controversy.

The second system: Bretton Woods

The 1930s break did not mean gold vanished from international monetary arrangements. In 1944, representatives of forty-four countries designed the Bretton Woods system. Other participating currencies were fixed—but adjustable—to the dollar, while the United States promised to convert official foreign dollar holdings into gold at $35 per ounce.

Ordinary Americans did not receive a restored right to redeem dollars for gold. The remaining gold link operated principally among monetary authorities. Bretton Woods became fully operational as currencies became convertible in 1958. Federal Reserve History: Creation of Bretton Woods

The arrangement solved one problem and created another. Global trade needed a growing supply of reserve assets. The United States supplied dollars to the world through international deficits. But the more dollars accumulated abroad, the less credible it became that every official holder could convert at $35 using the finite U.S. gold stock.

This tension is commonly called the Triffin dilemma: supplying the reserve currency supports global liquidity while eventually undermining confidence in its fixed conversion promise.

Why pressure built in the 1960s

Europe and Japan recovered from World War II and became stronger exporters. U.S. overseas spending and balance-of-payments deficits supplied more dollars abroad. Domestic inflation accelerated in the second half of the 1960s, making the fixed dollar-gold parity and fixed exchange rates harder to defend.

By 1961, outstanding dollar claims had begun to exceed the U.S. government’s gold stock, according to Federal Reserve History. The United States and foreign authorities used gold-pool arrangements, foreign-exchange intervention, swap lines, capital controls, and diplomatic pressure to delay conversion demands. These measures managed symptoms but did not resolve the basic mismatch. The Smithsonian Agreement

This sequence matters for causality. The dollar did not first lose credibility because Nixon unexpectedly removed a healthy gold link. The link was suspended after years of inflation, external imbalance, speculative pressure, and declining confidence in the ability to honor all claims at the fixed price.

August 15, 1971: closing the gold window

On August 15, 1971, Nixon announced a new economic policy. Its major elements included:

  • suspending official conversion of dollars into gold;
  • a temporary wage-and-price freeze; and
  • a temporary import surcharge.

Foreign governments could no longer present dollars to the U.S. Treasury for gold. Federal Reserve History describes the decision as the beginning of the end of Bretton Woods and notes that the administration faced both a looming gold run and domestic inflation. Nixon Ends Dollar Convertibility to Gold

The suspension was initially presented as temporary. In practice, convertibility did not return.

Did closing the gold window devalue the dollar?

Closing the window removed the promise to exchange official dollars for gold at $35, but it did not by itself announce one new universal market price for the dollar. Exchange rates had to be renegotiated or allowed to move.

In December 1971, the Smithsonian Agreement realigned major exchange rates and formally devalued the dollar within an attempted fixed-rate system. That arrangement did not solve the underlying imbalance. Pressure resumed, another devaluation followed, and major currencies moved to generalized floating in 1973. Federal Reserve History: The Smithsonian Agreement

The most accurate causal sequence is therefore:

  1. U.S. inflation and external deficits weakened confidence in the fixed parity.
  2. Foreign dollar claims grew relative to available U.S. gold.
  3. Conversion pressure made the $35 promise increasingly difficult to maintain.
  4. The United States suspended convertibility.
  5. Fixed exchange rates were realigned, then failed.
  6. Under floating rates, the dollar could depreciate or appreciate as markets and policy changed.

Ending convertibility enabled the system to adjust without gold redemption, but the imbalances that caused adjustment were already present.

Did leaving gold cause the Great Inflation?

It is too simple to say yes. Inflation was already rising before August 1971. Federal Reserve History traces the Great Inflation to a combination of overly expansionary monetary policy, mistaken beliefs about the unemployment-inflation trade-off, fiscal pressures, energy shocks, wage and price dynamics, and delayed policy correction. The weakness of Bretton Woods was part of that history, not a switch that created inflation from nothing. Federal Reserve History: The Great Inflation

Gold convertibility imposed a constraint, but a constraint is not the same as a complete monetary-policy rule. Gold-standard countries experienced inflation, deflation, banking panics, suspensions, and parity changes. A fiat system gives policymakers more flexibility; whether that flexibility produces stable prices depends on institutions, policy choices, fiscal conditions, supply shocks, credibility, and the economy’s response.

The 1971 wage-and-price freeze illustrates the distinction. It temporarily suppressed measured price increases but did not remove the monetary and real forces behind inflation. Price controls can delay or redirect adjustment; they do not create additional energy, labor, goods, or productive capacity.

Did the dollar become “backed by nothing”?

After the gold link ended, the dollar became irredeemable fiat currency. It is not a claim for a fixed amount of gold. That does not mean it has no institutional foundation.

Demand for dollars comes from several sources:

  • U.S. taxes and obligations are payable in dollars;
  • contracts, wages, prices, and debts are denominated in dollars;
  • the Federal Reserve manages the monetary base and short-term interest-rate framework;
  • U.S. Treasury securities provide a large reserve and collateral market;
  • the legal system enforces dollar contracts; and
  • global trade and finance continue to use dollars extensively.

These foundations can be managed well or poorly. Fiat currency removes a convertibility promise; it does not remove scarcity, credibility, policy constraints, or the possibility of appreciation and depreciation.

Why gold did not cap every kind of money perfectly

Even under a gold standard, the financial system created bank deposits and credit beyond the quantity of coins in circulation. Reserve requirements and convertibility constrained expansion, but they did not make every dollar a separate gold coin waiting in a vault. Confidence, bank balance sheets, central-bank policy, and international gold flows still mattered.

This is why gold systems could be fragile during panics. When many holders demanded gold or currency simultaneously, banks and central banks had to contract credit, obtain gold, suspend payments, or change the parity. The discipline was real, but so was the risk of procyclical tightening.

What this history means for investors

The history does not establish that gold must outperform fiat money, stocks, bonds, or productive businesses. It does establish that monetary regimes change and that nominal promises should be evaluated in purchasing-power terms.

Useful questions include:

  • Is a return quoted before or after inflation?
  • Does an asset produce cash flow, or does its value depend mainly on future resale?
  • What currency are the asset and liabilities denominated in?
  • Does a portfolio depend on one monetary outcome?
  • Can the investor remain solvent and liquid if inflation, deflation, rates, or exchange rates move unexpectedly?

Gold may diversify some portfolios, but it has no contractual yield and can experience long periods of weak real performance. Cash is stable in nominal dollars but exposed to inflation. Bonds provide contractual cash flows but carry inflation, interest-rate, and credit risks. Businesses can raise prices and grow, but their stocks can be overvalued or suffer operational losses. No asset makes monetary uncertainty disappear.

Bottom line

The United States left gold in two major stages. The 1933–34 policy ended domestic convertibility and deliberately devalued the dollar against gold to fight Depression-era deflation. The 1971 Nixon shock ended the remaining official international promise under Bretton Woods after years of inflation, external deficits, and pressure on U.S. gold reserves. Dollar devaluation and depreciation followed through negotiated and then floating exchange rates, but leaving gold was part of a longer causal chain—not a single event that independently explains every later price increase.
