๐ต Fiat Currency Fiat Currency
Fiat currency is government-issued money like the US dollar, euro, or yen. The law makes it legal tender and its value comes from public trust in the government โ not from being backed by gold or any other physical asset.
๐๏ธ The simple version โ money like a movie ticket
Think of a dollar bill like a movie ticket. The paper itself is nearly worthless, but everyone honors it because the issuer stands behind it. With fiat money, the issuer is the government. The word "fiat" is Latin for "let it be done" โ the money has value because the government declares it does, and the law says you must accept it for payments, taxes, and debts. That status is called being legal tender.
๐ฆ Who creates it, and why that's the point
A country's central bank (like the US Federal Reserve) issues its fiat money and can adjust how much of it exists. This is the whole reason fiat replaced the gold standard. By managing the money supply, a central bank can run monetary policy: easing in a downturn, tightening when prices climb. A currency tied to a fixed pile of gold can't do that.
๐ When did money stop being backed by gold?
For decades, major currencies could in theory be traded for gold. That changed in the early 1970s: the United States ended the dollar's link to gold (the "Nixon shock" of 1971), and by the 1976 Jamaica Accords all major world currencies had become fiat. Since then, no major currency is backed by a commodity โ only by trust.
๐ The trade-off: inflation risk
Being able to expand the money supply is powerful, but it has a cost. If too much money is created, each unit can buy less โ that's inflation. In extreme cases it becomes hyperinflation, where prices spiral out of control.
- ๐ฉ๐ช Weimar Germany โ prices doubled in days in the 1920s
- ๐ฟ๐ผ Zimbabwe โ banknotes in the trillions
- ๐ป๐ช Venezuela โ cash that lost value by the hour
๐ This inflation risk is exactly the contrast crypto fans point to: a coin with a fixed, unchangeable supply can't be printed more of.

โ FAQ
- Is fiat money still backed by gold in a vault?
- No. That stopped in the early 1970s when countries left the gold standard. Today there is no gold reserve you can swap your dollars for. Fiat money is backed only by law and public trust in the government that issues it.
- Why is Bitcoin often described as the opposite of fiat?
- A government can create more fiat money whenever it chooses, which can lower the value of each unit over time. Bitcoin's supply is capped and no single authority can expand it, so fans frame it as the opposite of fiat. Whether that makes it 'better' is a separate debate.
- Are stablecoins and CBDCs the same as fiat?
- Not exactly. A stablecoin is a crypto token built to track a fiat currency, usually pegged 1:1 to the US dollar, but it is issued by a company, not a government. A CBDC is a digital version of fiat issued by a central bank itself, so it is fiat in token form rather than a cryptocurrency.
