Inflation

Devaluation of money's purchasing power

In economics, inflation is an increase in the average price of goods and services in terms of money, though it originally referred to the increase of the money supply (monetary inflation) that can cause such a universal shift. This increase is measured using a price index, typically a consumer price index (CPI). When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money.
