# What Is Fiat Money?

**Fiat** comes from Latin — it means "let it be done" or "by decree." Fiat money is currency that has value because a government declares it does, and because people collectively agree to accept it. There is no gold in a vault backing your dollars. There is no silver tied to your euros. There is only trust.

This sounds precarious — and it is, in a way. But fiat money also has real advantages. Governments can expand or contract the money supply in response to economic conditions. Central banks can lower interest rates during a recession or raise them to cool inflation. None of this is possible when your currency is locked to a physical commodity.

> 💡 In plain terms
> Think about the cash in your wallet. Why does it have value? Not because of the paper. Not because of some gold in a vault. It has value because you believe the next person will accept it — and they accept it because they believe the person after them will too. It's a shared belief, reinforced by law and habit. Fiat money is, at its core, a collective act of faith.

Modern fiat money is managed by **central banks** — institutions like the US Federal Reserve, the European Central Bank, or the Bank of Japan. These institutions control interest rates, money supply, and lending conditions. They are, in effect, the high priests of the monetary system: setting the rules that determine how much your savings are worth tomorrow.

> ⚡ Why It Works
> Fiat money works extraordinarily well — when it's managed responsibly. The US has maintained the dollar's purchasing power reasonably well over decades (inflation notwithstanding). But the system's weakness is also its feature: it requires ongoing trust in institutions. And as we'll see, that trust is not evenly distributed across the world.
