Price stability is a macroeconomic condition in which the general level of prices for goods and services remains broadly constant over time, with inflation low, stable and predictable. It is the primary mandate of most central banks because it preserves the purchasing power of money, anchors expectations and supports sustainable economic growth. Central banks pursue price stability through monetary policy tools that influence interest rates, money supply and inflation expectations.
Overview
- Price stability does not mean zero inflation but a low, stable rate consistent with a well-functioning economy.
- Stable prices reduce uncertainty, lower risk premia and improve the allocation of resources.
- Central banks define explicit targets and adjust policy instruments to keep inflation near them.
