LAF (Liquidity Adjustment Facility)

The Liquidity Adjustment Facility forms the operational backbone of the RBI's monetary policy transmission. Under the LAF, banks can park their surplus funds with the RBI overnight through the reverse repo window, earning the reverse repo rate. Conversely, banks facing a short-term liquidity deficit can borrow overnight from the RBI through the repo window at the repo rate. Together, these two rates define the interest rate corridor — the band within which the overnight call money rate is expected to fluctuate, with the Marginal Standing Facility (MSF) rate as the ceiling and the Standing Deposit Facility (SDF) rate as the floor in the revised framework.

Before the LAF's introduction, the RBI used blunt instruments like changes in CRR or direct credit controls to manage liquidity, which were disruptive and lacked precision. The LAF introduced a market-based, daily mechanism to fine-tune liquidity, enabling smoother monetary policy transmission. After the Urjit Patel Committee report in 2014, the LAF framework was refined: the repo rate became the single policy rate, and the reverse repo and MSF rates were set as a symmetric corridor around it. The LAF corridor was subsequently narrowed from 200 basis points to 50 basis points, improving the precision of liquidity management.

The RBI further refined the LAF in 2022 by introducing the Standing Deposit Facility (SDF) as the floor, replacing the fixed-rate reverse repo. The SDF allows the RBI to absorb liquidity from banks without providing any collateral in return, giving the central bank greater flexibility during periods of surplus liquidity. During the post-COVID liquidity overhang of 2021–2022, the SDF became the primary tool to gradually absorb excess liquidity that had accumulated due to large government spending and RBI's asset purchases.

For participants in the Indian debt markets, the LAF rate corridor directly influences the pricing of commercial paper, certificates of deposit, treasury bills, and overnight indexed swaps. Money market funds managed to deliver returns broadly in line with the repo/reverse repo corridor during normal conditions. Any widening of this corridor, or a shift in the RBI's stance from 'withdrawal of accommodation' to 'neutral,' signals changing liquidity dynamics that immediately reprice short-duration debt instruments. LAF operations are thus a critical input for both treasury desks at banks and portfolio managers running liquid and ultra-short bond funds.
