Overview
Money and Banking forms the backbone of Macroeconomics, focusing on the mechanism of money supply and the regulatory control exerted by the Central Bank. For entrance exams, the focus is on the multiplier effect, liquidity management, and the specific mandates of the RBI in maintaining economic stability.
Functions of Money
Money is defined by its ability to act as a medium of exchange, a measure of value, and a store of value. Aspirants must distinguish between primary functions and secondary functions, specifically how money eliminates the double coincidence of wants inherent in the barter system.
- Medium of exchange (removes barter constraints)
- Measure of value (unit of account)
- Store of value (wealth preservation)
- Standard of deferred payment
Credit Creation by Banks
Commercial banks create credit through the process of demand deposits and fractional reserve banking. The core concept is the Money Multiplier, which determines the total money supply based on the initial primary deposit and the Cash Reserve Ratio (CRR).
- Credit Multiplier formula = 1 / LRR
- Total Money Creation = Initial Deposit × (1 / LRR)
- LRR = Legal Reserve Ratio (CRR + SLR)
- Banks only need to keep a fraction of deposits as reserves
RBI Functions
The Reserve Bank of India acts as the apex monetary authority and the regulator of the banking system. It functions as the 'Banker to the Government' and the 'Lender of Last Resort', ensuring financial stability and currency issuance.
- Issue of Currency (sole authority)
- Banker to the Government
- Custodian of Foreign Exchange Reserves
- Controller of Credit
Monetary Policy & Tools
The RBI regulates money supply using quantitative and qualitative tools. Quantitative tools like Repo Rate and OMO directly impact the availability of loanable funds, whereas qualitative tools target specific sectors of the economy.
- Repo Rate: Rate at which RBI lends to banks
- Reverse Repo Rate: Rate at which RBI borrows from banks
- CRR: Cash Reserve Ratio (mandatory cash reserve)
- SLR: Statutory Liquidity Ratio (liquid assets reserve)
- OMO: Open Market Operations (buying/selling government securities)
Formula Sheet
Money Multiplier = 1 / Legal Reserve Ratio (LRR)
Total Credit Creation = Initial Deposit × (1 / LRR)
Legal Reserve Ratio = Cash Reserve Ratio (CRR) + Statutory Liquidity Ratio (SLR)
Exam Tip
Always remember the inverse relationship: any increase in reserve ratios (CRR/SLR/Repo) leads to a contraction in money supply, while a decrease leads to an expansion.
Common Mistakes
- Confusing Repo Rate with Bank Rate (Repo is for short-term, Bank Rate is for long-term)
- Miscalculating money creation by failing to sum CRR and SLR into the LRR
- Assuming an increase in CRR increases money supply rather than decreasing it
