Definition
Gresham’s Law states that “bad money drives out good,” which means that when two forms of currency are in circulation that have different intrinsic values, the currency that is perceived as “bad” (or less valuable) will typically be used for transactions, while the currency that is viewed as “good” (more valuable) will be hoarded or removed from circulation. This principle primarily arose from a time when coins were made from precious metals, and fluctuations in their intrinsic value due to debasement often led to confusion and irrational economic behaviours.
| Good Money | Bad Money |
|---|---|
| Higher intrinsic value (e.g., gold or silver coins) | Lower intrinsic value (e.g., paper currency or debased coins) |
| Often hoarded as a store of value | Used for day-to-day transactions |
| More stable, less likely to fluctuate | Less stable, more prone to inflation |
| Circulates less often | Circulates more frequently |
Examples
- Historical Context: In medieval Europe, when coins made of silver were debased by mixing in less valuable metals, citizens would often keep their silver coins and use the lower-quality coins for transactions.
- Modern Application: In today’s currency markets, if both digital currencies and fiat money circulate together, people may prefer to hold on to their digital currencies (if they are perceived as more stable) for investment, while spending the fiat money.
Related Terms

Frequently Asked Questions
What happens when bad money drives out good? When bad money drives out good, it leads to inflation and economic instability, as the currency of higher value disappears from circulation, leading to more reliance on the bad currency.
Does Gresham’s Law apply to digital currencies? Yes, Gresham’s Law can be theorized in the context of digital currencies versus fiat money, where individuals might hoard more perceived valuable coins or tokens.
Is Gresham’s Law always true in all situations? Not always! Gresham’s Law applies primarily to scenarios where there are legal, currency values that make one form more enticing to hoard than another. It doesn’t apply in perfectly competitive markets without those distinctions.
