Monetary policy can influence spending and economic activity, but its effects do not arrive immediately or reliably. This lesson explains why policy takes time to work, why banks may hold excess reserves instead of lending, and why the degree of democratic control over central banks is debated.
Monetary policy works through a chain of decisions and responses. A central bank must first recognize an economic problem, decide how to respond, and change its policy stance. The change then affects financial conditions, including bank lending and interest rates. Businesses and households respond by adjusting investment, borrowing, and spending. Finally, those changes spread through the wider economy.
