Q.What are the instruments of monetary policy of RBI?

The Reserve Bank of India uses several instruments to regulate money supply and credit conditions in the economy.

Quantitative instruments control the overall volume of credit. The bank rate is the rate at which RBI lends to commercial banks for long periods; raising it makes borrowing costlier and contracts credit. The repo rate (repurchase rate) is the rate for short-term lending against securities, while the reverse repo rate is what RBI pays banks for their deposits with it — these two form a corridor that steers market interest rates. Open market operations involve RBI buying or selling government securities; purchases inject liquidity, sales absorb it. The cash reserve ratio (CRR) is the fraction of deposits banks must hold as cash with RBI, and the statutory liquidity ratio (SLR) is the fraction they must hold in liquid assets like government bonds — higher ratios reduce lendable funds. …

Monetary policy is the Reserve Bank of India's primary lever for managing the economy's money supply and credit conditions. The central bank doesn't directly hand out or withdraw cash from your pocket; instead, it influences how much money commercial banks can create and lend, which ripples through the entire economy. Think of the RBI as controlling the taps and valves in the banking system's plumbing.

The instruments fall into two broad categories: quantitative tools that change the overall volume of money and credit, and qualitative tools that influence where that credit flows.

Quantitative (General) Instruments

These affect the total supply of money in the economy, working through the banking system's reserves and lending capacity.

Repo Rate and Reverse Repo Rate

The repo rate is the interest rate at which commercial banks borrow short-term funds from the RBI against government securities. When the RBI raises the repo rate, borrowing becomes costlier for banks, so they lend less to businesses and households — money supply contracts, cooling inflation. The reverse repo rate is what the RBI pays banks for parking their surplus funds with it. A higher reverse repo rate encourages banks to deposit money with the RBI rather than lend it out, again tightening liquidity. These are the RBI's most actively used day-to-day policy levers.

Cash Reserve Ratio (CRR)

Every commercial bank must keep a certain percentage of its total deposits as cash reserves with the RBI. If the CRR is 4%, a bank with ₹100 crore in deposits must lock ₹4 crore with the central bank, leaving only ₹96 crore available for lending. Raising the CRR directly shrinks the money banks can lend, reducing the money multiplier effect. This is a blunt but powerful tool — the RBI uses it sparingly because it immediately affects bank profitability.

Statutory Liquidity Ratio (SLR)

Banks must hold a minimum percentage of their net demand and time liabilities in liquid assets — government securities, gold, or cash. Unlike CRR (which sits idle with the RBI), SLR assets earn interest but are still unavailable for commercial lending. A higher SLR squeezes the funds banks can deploy as loans. Historically, India used very high SLR rates (above 30% in the 1990s) to finance government deficits; today it's a secondary tool for liquidity management.

Open Market Operations (OMO)

The RBI buys or sells government securities in the open market. When it buys securities, it injects cash into the banking system — banks have more reserves, can lend more, money supply expands. When it sells securities, it mops up liquidity. OMOs are flexible and precise, allowing the RBI to fine-tune liquidity without changing headline rates.

Bank Rate

This is the rate at which the RBI lends long-term funds to commercial banks (without collateral, unlike repo). In practice, the bank rate has become less relevant since the introduction of the repo rate; it now mainly serves as a penal rate for banks that fail to maintain reserves. Changes in the bank rate signal the RBI's policy stance.

Qualitative (Selective) Instruments

These don't change the total money supply but steer credit toward or away from specific sectors.
