Monetary policy
Monetary policy influences inflation, demand and financial conditions through interest rates, central-bank balance sheets, expectations and the functioning of money and credit markets.
Definition
Monetary policy is the use of a central bank's instruments and communications to influence monetary and financial conditions in pursuit of statutory objectives such as price stability and, in some jurisdictions, employment or output stabilization.
Objectives
Central-bank mandates differ, but modern frameworks commonly place price stability at their centre. Monetary policy may also seek to reduce cyclical instability, support employment or safeguard monetary-system functioning. These aims can align over time yet conflict during supply shocks, when inflation rises as output weakens.

Rules, discretion and credibility
A policy rule links decisions systematically to economic conditions; discretion permits case-specific judgment. In practice, central banks combine structured frameworks with judgment because the economy is uncertain and policy works with variable lags. Independence can protect decisions from short-term political pressure, while transparency, accountability and a clear mandate support democratic legitimacy and credible expectations.
