Definition
Currency debasement is the reduction of a currency's intrinsic or real value by its issuer. In the era of metallic coinage this meant lowering the precious-metal content of coins while keeping their face value unchanged, by mixing in base metals, shrinking coin weight, or clipping metal from the edges. In modern fiat systems the analogous mechanism is expanding the money supply faster than the economy's output of goods and services.
A long historical record
The Roman denarius is the classic case: nearly pure silver under the Republic, its silver content was steadily cut over roughly three centuries until it was a token of its former self, contributing to severe price inflation in the late empire. Henry VIII's Great Debasement of the 1540s slashed the silver content of English coinage, and Weimar Germany's money printing of 1921 to 1923 produced one of history's fastest hyperinflations.
The modern parallel
Advocates of hard money argue that creating new money, whether through quantitative easing or direct deficit financing, debases the currency in the same way a Roman mintmaster diluted silver: the purchasing power of every existing unit falls as the total supply rises. This historical continuity is a core motivation behind the sound money case for an asset whose supply no issuer can expand, such as Bitcoin with its fixed 21-million cap.
