Reverse Repo Rate

The reverse repo rate is a monetary-policy instrument denoting the interest rate at which a central bank borrows funds from commercial banks against the collateral of eligible government securities, with an agreement to repurchase those securities at a future date. In India, the instrument derives its legal and institutional authority from the Reserve Bank of India Act, 1934, and operates within the Liquidity Adjustment Facility (LAF) introduced in June 2000 on the recommendations of the Narasimham Committee (1998). The rate is determined by the six-member Monetary Policy Committee (MPC), constituted under the amended RBI Act following the Finance Act, 2016, which inserted a statutory inflation-targeting framework anchored to a Consumer Price Index target of 4 percent with a tolerance band of plus or minus 2 percent. The reverse repo rate is the mirror image of the repo rate: where the repo rate injects liquidity into the system, the reverse repo rate withdraws it.

Procedurally, the mechanism functions as a collateralised borrowing transaction initiated by the central bank to absorb surplus liquidity from the banking system. When commercial banks hold idle funds beyond their statutory requirements, they park these funds with the RBI by purchasing government securities, and the RBI agrees to repurchase the securities the following day (in the case of overnight operations) at a price reflecting the reverse repo rate. The bank earns interest at the reverse repo rate on the funds it lends to the central bank, while the security serves as collateral that protects the lender against default. Because the transaction is risk-free and fully collateralised, no bank will lend in the interbank or money market at a rate below what the central bank offers, which is why the reverse repo rate functions as the floor of the LAF corridor.

A structural refinement entered the framework in February 2014, when the RBI, acting on the recommendations of the Urjit Patel Committee, introduced the Marginal Standing Facility (MSF) rate as the ceiling and reaffirmed the reverse repo as the floor, with the repo rate as the central policy rate. The corridor was further reconfigured in April 2022, when the RBI introduced the Standing Deposit Facility (SDF) as a new floor for the corridor, replacing the fixed-rate reverse repo as the primary liquidity-absorption tool. The SDF allows the RBI to absorb liquidity without offering government securities as collateral, addressing the operational constraint that the reverse repo window required the central bank to hold an adequate stock of securities. Since then the reverse repo rate has been retained on the books but rendered largely dormant as an active instrument, with the SDF rate set 25 basis points below the repo rate.

In contemporary practice, the MPC announces the policy rate corridor at the conclusion of its bi-monthly meetings at the RBI's central office in Mumbai. During the COVID-19 pandemic, the RBI cut the reverse repo rate to 3.35 percent in May 2020 to discourage banks from parking excess funds and to push credit into the real economy, while the repo rate stood at 4.00 percent—a deliberate widening of the corridor to 65 basis points to ease financial conditions. By contrast, central banks abroad use functionally analogous instruments: the US Federal Reserve operates an Overnight Reverse Repurchase Agreement (ON RRP) facility administered by the Federal Reserve Bank of New York, and the European Central Bank employs a deposit facility rate as its corridor floor.

The reverse repo rate must be distinguished from several adjacent instruments. It is the inverse of the repo rate, which governs central-bank lending to banks rather than borrowing from them. It differs from the bank rate, which is a longer-term, unsecured lending rate now aligned with the MSF rate and largely symbolic. It is also distinct from the Cash Reserve Ratio (CRR) and Statutory Liquidity Ratio (SLR), which are mandatory reserve requirements that immobilise a portion of deposits, whereas reverse repo participation is voluntary and remunerated. The reverse repo absorbs liquidity at the discretion of banks seeking a safe return, while CRR and SLR are non-negotiable regulatory floors.

Several controversies and developments attend the instrument. Economists have debated whether a low reverse repo rate effectively channels liquidity into productive lending or merely depresses banks' returns without stimulating credit, a concern acute during periods of risk aversion when banks prefer safe parking to lending. The 2022 introduction of the SDF prompted commentary on whether the reverse repo rate retains analytical relevance for examination and policy purposes; the RBI has clarified that the fixed-rate reverse repo remains available as an instrument at its discretion, even if operationally superseded. The widening and narrowing of the corridor itself became a signalling device, with a wider corridor indicating an accommodative posture and a narrower one signalling normalisation.

For the working practitioner—whether a civil-services aspirant preparing for the General Studies Paper III syllabus, a banking analyst, or a policy researcher—the reverse repo rate remains essential for understanding how a central bank manages systemic liquidity and transmits monetary policy. It illustrates the corridor logic that governs short-term interest rates, clarifies the asymmetry between liquidity injection and absorption, and demonstrates how institutional reform (the LAF, the MSF, and the SDF) progressively refined the toolkit. Even in its diminished operational role, the reverse repo rate furnishes the conceptual scaffolding for analysing the floor of the policy corridor and the RBI's calibration of credit conditions across the business cycle.
