What Is Fiat Currency? A Plain-Language Guide
Fiat currency is government-issued money that is not convertible into a fixed amount of gold or another commodity. Its usefulness depends on law, public acceptance, monetary institutions and confidence in what it can buy.
The U.S. dollar, euro and many other modern currencies are fiat currencies. They are used as units of account, media of exchange and ways to settle obligations. They do not give the holder a right to redeem each unit for a fixed weight of gold or silver.
The short answer
Fiat money is accepted because governments designate it as legal tender, institutions support the payment system and people generally trust others will accept it. Gold and silver bullion are commodities with market prices; they are not replacements for the everyday payment system.
What "Fiat" Means
In a fiat system, currency is not convertible into a fixed quantity of a commodity. The Federal Reserve describes modern fiat money as legal tender by government decree whose value depends on trust that others will accept it and that its purchasing power will remain reasonably stable.
U.S. coins and currency, including Federal Reserve notes, are legal tender for debts, public charges, taxes and dues. Legal tender status does not mean every private business must accept cash in every situation.
How Fiat Currency Works
Households and businesses use currency and bank money to quote prices, receive wages, pay bills and settle transactions. Central banks influence financial conditions through monetary policy, while commercial banks and payment networks help move money through the economy.
The value of a fiat currency is not fixed. Purchasing power can change with inflation or deflation, and exchange values move against other currencies. Sound institutions can support confidence, while severe fiscal, political or monetary instability can damage it.
Fiat Currency Compared With Physical Bullion
Currency is optimized for payments and accounting. Bullion is a physical commodity that people may buy or sell at market prices. A gold coin does not replace a checking account, and holding cash does not provide direct ownership of a scarce physical metal.
Some people compare bullion with currency because gold has a long monetary history and is held by central banks. That comparison should not become a promise that bullion will always rise when inflation increases or that it can eliminate financial risk.
