Quick Answer
Monetary economics studies how money is created, managed, and used to influence an economy. In India, the Reserve Bank of India (RBI) sits at the centre of this system — setting interest rates, regulating banks, controlling money supply, and targeting inflation. India's monetary framework adopted formal inflation targeting in 2016, with the RBI mandated to keep CPI inflation at 4% (within a 2–6% band). Understanding this topic means understanding how repo rate changes ripple through bank loans, business investment, household spending, and ultimately prices — all through a banking system that serves both urban corporates and rural Jan Dhan account holders.
