Q1. During periods of excess liquidity in the banking system, what role does the reverse repo rate play in the RBI's monetary policy operations, and what impact does it have on commercial banks?
- (a) It encourages banks to borrow more from the RBI and lend to the public
- (b) It allows the RBI to absorb surplus liquidity by offering an interest rate on funds parked by banks, thus discouraging excessive lending
- (c) It forces banks to invest solely in foreign assets, reducing inflation risk
- (d) It mandates that all banks maintain higher CRR, thereby tightening liquidity
Answer & solution
Answer: (b) It allows the RBI to absorb surplus liquidity by offering an interest rate on funds parked by banks, thus discouraging excessive lending
The reverse repo rate is the rate at which the RBI borrows from banks — banks park their surplus cash with the RBI against government securities and earn interest.
When the system has too much money, a higher reverse repo rate makes parking funds with the RBI attractive, so liquidity is absorbed and banks lend less freely.
Revision note — Repo, reverse repo and the liquidity corridor
• Repo rate: the RBI lends to banks against government securities — the main policy rate.
• It is set by the Monetary Policy Committee (MPC) of six members, with an inflation target of 4 per cent (± 2 per cent).
• Reverse repo rate: the RBI borrows from banks; it has stayed at 3.35 per cent since May 2020 and is now used only for occasional variable-rate auctions.
• Since April 2022 the floor of the corridor is the Standing Deposit Facility (SDF) at repo minus 25 basis points, where banks park money without collateral.
• The ceiling is the Marginal Standing Facility (MSF) at repo plus 25 basis points.
• The repo rate stood at 5.25 per cent after the MPC's cut of 25 basis points on 5 December 2025.
• Both operations run under the Liquidity Adjustment Facility (LAF), introduced in June 2000 on the recommendation of the Narasimham Committee II.
• Other quantitative tools: CRR (cash kept with the RBI, no interest), SLR (liquid assets kept by the bank itself), bank rate and open market operations.
• Moral suasion and margin requirements are qualitative tools.
Do not mix these up
• Repo vs reverse repo — in a repo the RBI lends and injects liquidity; in a reverse repo the RBI borrows and absorbs liquidity. The reverse repo rate is always the lower of the two.
• Reverse repo vs SDF — both absorb liquidity, but the reverse repo needs government securities as collateral while the SDF does not.
