Overview
Money and Banking is a fundamental macroeconomics topic that examines how money facilitates trade and how central banks regulate liquidity. It is a high-scoring area that tests your conceptual understanding of monetary mechanisms and the operational roles of the RBI in the Indian economy.
Functions of Money
Money serves as a medium of exchange, solving the 'double coincidence of wants' problem inherent in the barter system. It acts as a unit of account, a store of value, and a standard of deferred payment.
- Medium of exchange: Eliminates barter complexity
- Measure of value: Common denominator for all goods
- Store of value: Purchasing power over time
- Standard of deferred payment: Facilitates credit contracts
Money Supply (M1-M4)
Money supply is a stock variable representing the total currency held by the public and demand deposits. In India, RBI classifies these into four measures of liquidity known as M1, M2, M3, and M4.
- M1 = Currency with public + Demand deposits
- M2 = M1 + Post office savings deposits
- M3 = M1 + Net time deposits of banks (Broad Money)
- M4 = M3 + Total post office deposits (excluding NSC)
Credit Creation by Commercial Banks
Commercial banks create credit through the process of money multiplication based on primary deposits. The volume of credit is inversely proportional to the Legal Reserve Ratio (LRR).
- Credit Multiplier = 1 / LRR
- LRR = Cash Reserve Ratio (CRR) + Statutory Liquidity Ratio (SLR)
- Initial deposit determines total money creation capacity
- Banks maintain only a fraction of deposits as reserves
RBI Functions & Monetary Policy
The RBI acts as the central bank of India, responsible for currency issuance, acting as a banker to the government, and controlling the money supply. It utilizes both quantitative and qualitative tools to manage inflation and growth.
- Repo Rate: Rate at which RBI lends to banks
- Reverse Repo: Rate at which RBI borrows from banks
- CRR: Minimum cash reserve to be held with RBI
- SLR: Percentage of deposits held as liquid assets by banks
- Open Market Operations: Buying/selling government securities
Formula Sheet
Money Multiplier = 1 / LRR
Total Money Creation = Initial Deposit * (1 / LRR)
M1 = Currency + Demand Deposits
Exam Tip
Always visualize the LRR inverse relationship: if the RBI increases CRR or SLR, it drains liquidity and reduces the credit creation capacity of the banking system.
Common Mistakes
- Confusing M3 (Broad Money) with M1 (Narrow Money) in liquidity calculations.
- Assuming higher CRR increases the money supply rather than decreasing it.
- Forgetting that Time Deposits are excluded from M1 but included in M3.
