Monetary policy aims to control money supply, interest rates, and achieve economic growth. The objectives of monetary policy are economic growth, full employment, price stability, neutrality of money, and exchange rate stability. Monetary policy tools include expansionary policy which increases money supply and lowers interest rates, and contractionary policy which decreases money supply and raises interest rates. Instruments of monetary policy include quantitative measures like open market operations and changes in reserve requirements, and qualitative measures like moral suasion and publicity.
