Instruments of Monetary Policy
Once the objectives of monetary policy are clear, the next natural step is to understand how the RBI actually implements it. For this, the central bank uses a set of policy tools called instruments of monetary policy.
Broadly, these instruments are classified into two categories:
- Quantitative (General) Instruments
- Qualitative (Selective) Instruments
Quantitative Methods of Monetary Policy
Quantitative methods are instruments used by the Reserve Bank of India to directly regulate the volume of money and credit in the economy.
Key Characteristics
- Affect the entire banking system
- Influence interest rates, inflation, and growth
- Operate by changing the amount of lendable resources with banks
| Category | Instrument | What it Means | How it Works | Policy Impact |
| Reserve Ratios | Cash Reserve Ratio (CRR) | Percentage of a bank’s Net Demand and Time Liabilities (NDTL) that must be kept as cash with RBI. | Banks cannot use this portion for lending. | ↑ CRR → Lending capacity falls → Money supply decreases (inflation control). ↓ CRR → Banks lend more → Money supply increases (growth stimulus). |
| Statutory Liquidity Ratio (SLR) | Percentage of NDTL that banks must maintain in liquid assets such as cash, gold, or government securities. | Maintained by banks themselves, not with RBI. | ↑ SLR → Less funds available for loans → Contraction of credit. ↓ SLR → More funds for lending → Credit expansion. | |
| Liquidity Adjustment Facility (LAF) | Repo Rate | Rate at which RBI lends short-term funds to banks against government securities. | Banks borrow funds from RBI to meet liquidity needs. | ↑ Repo → Borrowing cost rises → Loans become expensive → Inflation control. ↓ Repo → Borrowing cheaper → Credit expansion → Growth. |
| Reverse Repo Rate | Rate at which RBI borrows money from banks. | Banks park excess liquidity with RBI. | ↑ Reverse Repo → Banks prefer depositing with RBI → Liquidity reduced in market. | |
| Marginal Standing Facility (MSF) | Emergency borrowing window allowing banks to borrow overnight from RBI against government securities. | Used when banks face acute liquidity shortages. | Higher rate discourages frequent use and stabilizes liquidity. | |
| Standing Deposit Facility (SDF) | Facility allowing banks to deposit surplus funds with RBI without collateral. | RBI absorbs excess liquidity from the banking system. | Helps control surplus liquidity and manage inflation. | |
| Market-Based Instruments | Bank Rate | Long-term rate at which RBI lends to commercial banks without repurchase agreement. | Influences long-term interest rates in the economy. | ↑ Bank Rate → Cost of borrowing increases → Credit contraction. |
| Open Market Operations (OMO) | Buying or selling of government securities by RBI in the open market. | Purchase injects liquidity; sale absorbs liquidity. | Key tool for managing money supply. | |
| Forex Swaps | RBI buys/sells foreign currency while simultaneously agreeing to reverse the transaction later. | Used to manage rupee liquidity and exchange rate pressures. | Injects or absorbs liquidity depending on direction of swap. | |
| Market Stabilisation Scheme (MSS) | Government issues special bonds/securities to absorb excess liquidity from the market. | Liquidity withdrawn without affecting fiscal deficit. | Used during periods of large capital inflows or surplus liquidity. |
