Introduction
Fiat money (or fiat currency) is government-issued legal tender not backed by physical commodities like gold or silver. Unlike commodity money, its value derives from market forces—supply and demand—and institutional trust rather than intrinsic worth.
Key characteristics:
- Declared legal tender by governing authorities.
- No inherent value (not redeemable for commodities).
- Value fluctuates based on economic conditions.
Governments favor fiat currencies for their flexibility in monetary policy, enabling controlled responses to inflation, recessions, and other financial challenges.
Fiat Money vs. Commodity/Representative Money
Fiat currency emerged as an alternative to:
- Commodity Money: Physical items with intrinsic value (e.g., gold coins, silver bars).
- Representative Money: Certificates exchangeable for a commodity (e.g., gold-backed banknotes).
Unlike these, fiat money lacks physical backing. Modern economies exclusively use fiat systems, managed by central banks to regulate money supply and stability.
