Fiat currency is money that a government declares to be legal tender but that is not backed by a physical commodity such as gold. The pound, the euro and the US dollar are all fiat currencies. Their value rests on trust in the government and central bank that issue them.

Fiat vs money backed by gold

Under a gold standard, a note could be swapped for a fixed amount of gold. Most countries left that system during the 20th century; the US ended the dollar's link to gold in 1971. Since then, major currencies have been fiat money.

Who controls the supply

Central banks, such as the Bank of England, set interest rates and can create money to steer inflation and the economy. That flexibility is the main strength of fiat money, and printing too much is its main risk, because it can drive high inflation.
