Fiat Money

Currency that has value only by government decree, and the world it created.

What is Fiat Money?

Take a dollar bill out of your wallet. What backs it? Not gold — that link was cut in 1971. Not silver, not oil, not anything you can touch. The only thing backing that bill is a government decree: “This is money because we say so.”

That’s what “fiat” means. It’s Latin for “let it be done” — an order from above. Fiat money is currency that has value because the law demands you accept it, not because it’s scarce, useful, or chosen by the market.

Every currency in the world today — dollars, euros, yen, won — works this way.

History of Fiat Money

Fiat money is a relatively recent experiment in human history:

  • Before 1971: The dollar was exchangeable for gold (1 ounce of gold = $35)
  • August 15, 1971: President Nixon halted gold convertibility (“Nixon Shock”)
  • After 1971: All major currencies became pure fiat money disconnected from gold

Throughout most of human history, currency was physical assets like gold and silver. The current fiat money system has a history of only about 50 years.

Problems with Fiat Money

Unlimited Issuance

The fundamental problem with fiat money is that there are no physical constraints on issuance. Central banks can create trillions of won with a few keyboard strokes.

Declining Purchasing Power

The result of unlimited issuance is continuous decline in purchasing power. Since 1971, the dollar’s purchasing power has declined by more than 87%. Over the same period, the price of gold rose from $35 to over $2,500.

Cantillon Effect

Newly issued money does not reach everyone simultaneously. Governments, large banks, and financial institutions receive new money first, while ordinary citizens receive it later. Those who receive it first can purchase at prices that haven’t risen yet, while those who receive it later must bear already-inflated prices.

This is why currency issuance is a regressive wealth redistribution mechanism.

Moral Hazard

If the government can infinitely print money, it doesn’t need to directly tax citizens to pay for wars. Historically, large-scale wars have accompanied fiat currency systems.
