Fiat currency and the gold standard are two different answers to a single question: what makes a dollar worth a dollar? Under a gold standard, every unit of currency is redeemable for a fixed amount of physical gold held in government vaults. Under a fiat system, money has value because the government declares it legal tender and because people agree to accept it. The United States operated on some form of gold standard for most of its history and fully left it in 1971. Since then, by Federal Reserve consumer price data, the dollar has lost roughly 88% of its purchasing power. That number is the headline in the fiat currency vs. gold standard debate, but it is not the whole story, because the gold era had costs of its own.
What Each System Actually Is
A gold standard ties paper money to a fixed weight of gold. The government promises that anyone holding currency can exchange it for physical gold at a set rate, and to make good on that promise it has to hold massive reserves. The money supply is effectively capped by how much gold the country owns. No new gold, no new money.
The Gold Standard Act of 1900 made this arrangement official in the United States, setting the dollar at a value that worked out to about $20.67 per troy ounce of gold.1Federal Reserve Bank of Richmond. Federal Reserve – An Anchor of Gold A twenty-dollar bill was, in a legal sense, a claim on roughly one ounce of gold at the Treasury.
Fiat currency has no intrinsic value and is not redeemable for any commodity. A twenty-dollar bill is worth twenty dollars because the government says it is and because the economy runs on the shared expectation that it will still be accepted tomorrow. People accept these notes because they need them to pay taxes, settle debts, and buy groceries. Federal law designates U.S. coins and currency as legal tender for all debts, public charges, taxes, and dues.2Office of the Law Revision Counsel. 31 U.S. Code 5103 – Legal Tender Under a fiat system, the government can expand or contract the money supply based on economic conditions rather than the contents of a vault.
The institution that does the expanding and contracting is the Federal Reserve, created by the Federal Reserve Act of 1913 to give the country a more flexible monetary framework.3Federal Reserve Board. Federal Reserve Act Section 2A of that Act gives the Fed what is now known as the dual mandate: maximum employment, stable prices, and moderate long-term interest rates.4Federal Reserve. What Economic Goals Does the Federal Reserve Seek to Achieve Through Its Monetary Policy The Fed pursues those goals by raising and lowering interest rates, adjusting bank reserve requirements, and buying and selling government securities. None of those tools work the same way under a gold standard, because the money supply is already dictated by the metal.
How the United States Moved from Gold to Fiat
The shift happened in stages, not all at once.
In 1933, President Franklin Roosevelt signed Executive Order 6102, requiring individuals and corporations to surrender most of their gold coins, bullion, and gold certificates to the Federal Reserve in exchange for paper currency at $20.67 per ounce. People could keep up to $100 in gold coins and anything with recognized collector value, but most private gold moved into government hands.5The American Presidency Project. Executive Order 6102 – Forbidding the Hoarding of Gold Coin, Gold Bullion and Gold Certificates The Gold Reserve Act of 1934 then transferred all monetary gold to the Treasury and revalued it from $20.67 to $35 per ounce, which devalued the dollar by about 40% in one move and gave the government more room to expand the money supply within the formal rules of the standard.6FRASER. Gold Reserve Act of 1934
After World War II, the Bretton Woods system pegged foreign currencies to the dollar and left the dollar convertible to gold at $35 per ounce for foreign governments, though not for private citizens.7Office of the Historian. Nixon and the End of the Bretton Woods System, 1971-1973 By the late 1960s, U.S. gold reserves were shrinking as foreign nations redeemed dollars for metal. On August 15, 1971, President Richard Nixon suspended the dollar’s convertibility into gold, cutting the last official link between the two.8Federal Reserve History. Nixon Ends Convertibility of U.S. Dollars to Gold and Announces Wage/Price Controls By March 1973 the major economies had moved to floating exchange rates, where currency values are set by markets rather than fixed to gold.
What the Gold Standard Does Well, and Badly
A gold standard imposes discipline. Because the government cannot print money beyond its gold reserves, it is structurally harder to spend recklessly or inflate the currency away. Exchange rates between gold-standard countries stay stable because each currency represents a defined weight of metal, which makes international trade more predictable. Gold’s scarcity acts as a built-in brake on runaway inflation.
That brake is real. Hyperinflation has occurred repeatedly under fiat systems and never under a functioning gold standard. In Germany’s Weimar Republic the exchange rate went from about 4 marks per dollar before World War I to 1 trillion marks per dollar by late 1923. Zimbabwe hit a daily inflation rate of 98% in early 2009. Yugoslavia reached a monthly inflation rate of 313 million percent in January 1994. Venezuela’s inflation exceeded 1,000,000%. You cannot print gold, so you cannot inflate a gold-backed currency into oblivion.
The cost of that discipline is the inability to respond when the economy falls apart. Research from the National Bureau of Economic Research found that during the Great Depression, countries that abandoned the gold standard recovered faster than those that stayed on it. The study documented a “close correspondence between deflation and nations’ adherence to the gold standard,” and concluded that the standard transmitted and amplified contractionary shocks across borders.9National Bureau of Economic Research. The Gold Standard, Deflation, and Financial Crisis in the Great Depression – An International Comparison Deflation under the gold standard triggered banking panics and increased the real burden of debt, feeding a cycle that governments on gold could not break.
The broader historical record shows wild price swings under gold. Prices could fall 30 to 50 percent over a decade and then rise sharply the next, depending on gold discoveries and trade flows. Savers were rewarded in some decades and wiped out in others.
What Fiat Does Well, and Badly
Flexibility is fiat’s core advantage. When a recession hits, a central bank can cut interest rates, buy government securities, and expand the money supply to support activity. When inflation runs hot, it can raise rates to cool things off. Under a strict gold standard, those tools do not exist in the same form, because monetary policy is dictated by reserves and mining output rather than economic need.
The post-1971 fiat era in the United States has had no extended period of deflation. Moderate, roughly predictable inflation turns out to be easier for households and businesses to plan around than the swings in both directions that marked the gold years.
The price is purchasing power. Federal Reserve data shows the dollar’s purchasing power, measured by consumer prices, falling from an index value of 251.1 in January 1971 to 30.8 by September 2025. That is roughly an 88% loss over 54 years. A grocery run that cost $10 in 1971 costs about $80 today. Central banks under the current system target roughly 2% annual inflation as a deliberate compromise, treating gradual erosion as the cost of flexibility.
Neither system solves the purchasing-power problem cleanly. Gold prevents inflation but invites deflation. Fiat prevents deflation but invites inflation. Which tradeoff is better depends on whether you worry more about your dollars slowly buying less or about the government being unable to act when the economy breaks.
How Currency Value Is Set Now
Under a gold standard, exchange rates are essentially fixed because each currency represents a specific weight of gold. In a fiat world, exchange rates float on international markets, reflecting a constantly shifting read on each country’s inflation, debt, interest rates, and political stability. Floating rates act as shock absorbers: if a country’s economy weakens, its currency drops, which makes its exports cheaper and helps it recover. A fixed gold-based rate removes that adjustment.
The U.S. dollar occupies a particular position in this arrangement. As of mid-2025, roughly 58% of the world’s foreign exchange reserves are held in dollars, making it the dominant global reserve currency.10CEPR. The Dollar’s Status Through the Lens of Foreign Exchange Reserves That creates steady global demand for dollars independent of U.S. economic fundamentals, and it also means Federal Reserve decisions move the global economy in ways no gold-era central bank could.
Owning Gold Under the Current System
If the fiat side of the debate worries you, you can hold gold directly, but that has not always been true. Private gold ownership was effectively banned in the United States from 1933 until Public Law 93-373 took effect on December 31, 1974. President Gerald Ford signed Executive Order 11825 the same day, revoking the Roosevelt-era orders that had restricted ownership.11The American Presidency Project. Executive Order 11825 – Revocation of Executive Orders Pertaining to the Regulation of the Acquisition of, Holding of, or Other Transactions in Gold Starting January 1, 1975, Americans could again own gold in any form.
The IRS classifies physical gold as a collectible. Long-term capital gains on collectibles are taxed at a maximum rate of 28%, compared with the 20% maximum on most other long-term capital gains such as stocks.12Internal Revenue Service. Topic No. 409 – Capital Gains and Losses Gold held less than a year is taxed at ordinary income rates. State sales tax treatment varies, with some states exempting bullion and others charging the standard rate.
Retirement accounts carry a narrow exception. The tax code generally treats buying a collectible inside an IRA as an immediate taxable distribution, but it carves out certain U.S. government gold coins and gold bullion meeting minimum fineness standards, provided the bullion is held by an approved trustee.13Office of the Law Revision Counsel. 26 U.S. Code 408 – Individual Retirement Accounts You cannot buy a gold bar for a self-directed IRA and keep it at home. It has to sit in a qualifying depository.
