RBI as the Monetary Authority
As the monetary authority. RBI controls the supply of money in the economy. It does this mainly through interest rates. The goal is to keep prices stable while supporting strong economic growth.
The main objectives of monetary policy are clear and exam-friendly:
- To control inflation and keep prices stable.
- To stabilise the exchange rate of the rupee.
- To maintain a healthy balance of payments.
- To attain overall financial stability.
- To strengthen the banking system.
Quantitative Measures of Credit Control
Quantitative tools affect the total volume of credit in the system. They apply to all banks equally. These are the most heavily tested tools, so learn each one well.
Bank Rate Policy
The bank rate is the official rate at. RBI rediscounts eligible bills held by commercial banks. To curb inflation and tighten money supply, RBI raises the bank rate. This makes borrowing costlier and slows credit growth.
Repo Rate
The repo rate is the rate at. RBI lends short-term funds to banks against securities. When the repo rate rises, borrowing from RBI becomes more expensive. Banks then pass on the higher cost, cooling demand.
Reverse Repo Rate
The reverse repo rate is the rate at. RBI borrows money from banks. A higher reverse repo rate tempts banks to park more funds with RBI. This pulls excess liquidity out of the market.
Cash Reserve Ratio (CRR)
CRR is the portion of total deposits a bank must keep with RBI as a reserve. This money earns no interest. Raising CRR reduces the funds banks can lend, tightening credit.
Statutory Liquidity Ratio (SLR)
SLR is the share of deposits a bank must hold in safe liquid assets like cash. Gold, or approved government securities. It ensures bank solvency. A higher SLR also leaves less room for lending.
Open Market Operations (OMO)
Through OMO. RBI directly buys or sells government securities. Bills in the open market.
Selling securities absorbs liquidity. Buying them injects money into the system. OMO is a flexible, day-to-day credit tool.
Exam tip: Rate values like repo. CRR, and SLR change at every monetary policy review. Do not memorise old figures blindly. Always confirm the current rates on the latest official RBI / IIBF notification close to your exam date.

|---|---|---|

| SLR | Deposits held as liquid assets | Lending capacity reduced |

Qualitative Measures of Credit Control
