The Reserve Bank of India (RBI) is the central bank of India that controls the country's monetary policy and the rupee. RBI was established in 1935 and plays an important role in the government's development strategies. As India's monetary authority, RBI supervises the financial system, issues currency, manages foreign exchange reserves, acts as a bank and debt manager to the government, and performs developmental functions through research and data sharing. RBI uses various monetary policy tools like open market operations, bank rates, cash reserve ratios, and liquidity ratios to regulate money supply and achieve objectives like low inflation and economic growth.
