The Reserve Bank of India uses various monetary policy instruments to achieve its objectives of price stability and economic growth. These include varying reserve ratios like the cash reserve ratio, using open market operations to purchase and sell government securities, and adjusting policy rates like the discount rate. The ultimate goals of monetary policy are to influence total spending, inflation, and other macroeconomic indicators through acting on monetary aggregates and interest rates. In recent decades, the RBI's monetary policy has focused on stabilizing inflation and liberalizing the economy.
