What Happened
- The Reserve Bank of India (RBI) announced plans to inject substantial durable liquidity into the banking system to prevent short-term interest rates from rising sharply above the policy repo rate.
- In early March 2026, the RBI conducted two Open Market Operation (OMO) purchase tranches of ₹50,000 crore each (total ₹1,00,000 crore), timed to offset mid-month advance tax and GST outflows that typically create acute seasonal liquidity tightening.
- The first ₹50,000 crore OMO was completed on March 9, 2026; the second was scheduled for March 13, 2026.
- Alongside OMOs, the RBI deployed dollar-rupee buy-sell swaps (purchasing US dollars from banks for immediate delivery, with a commitment to sell them back at a pre-determined future rate) to simultaneously inject rupee liquidity and stabilise the exchange rate.
- These operations collectively form part of the RBI's strategy to keep the weighted average call money rate (WACR) anchored near the 5.25% policy repo rate amid evolving liquidity conditions.

Open Market Operations (OMO) — Mechanism and Purpose
Open Market Operations (OMOs) are outright purchases or sales of government securities (G-Secs) by the Reserve Bank from/to the banking system. When the RBI purchases G-Secs, it pays banks in rupees, thereby injecting durable (long-term) liquidity into the system; when it sells, it absorbs liquidity. OMOs are distinct from short-term Repo operations under the Liquidity Adjustment Facility (LAF): repo/reverse repos are collateralised, short-tenor instruments, while OMOs are outright transactions that permanently shift the central bank's balance sheet and create sustained liquidity. OMOs are the RBI's primary tool for durable liquidity management.
- Statutory basis: Section 17(8) of the Reserve Bank of India Act, 1934 — empowers the RBI to buy and sell government securities
- OMO purchases expand the monetary base (M0); their transmission to broader money supply depends on bank lending behaviour
- OMOs are distinct from Market Stabilisation Scheme (MSS) operations, which are undertaken at the government's initiative to sterilise capital inflows
- Securities purchased through OMOs remain on the RBI's balance sheet as assets
Connection to this news: The ₹1 lakh crore OMO injection was calibrated to ensure banking system liquidity remains in surplus, so that short-term market rates (WACR, T-bill yields) stay close to the 5.25% policy rate rather than drifting toward the 5.50% MSF ceiling.
Liquidity Adjustment Facility (LAF) and the Interest Rate Corridor
The Liquidity Adjustment Facility (LAF) is the RBI's framework for day-to-day liquidity management and interest rate signalling. It operates through three instruments: (i) Repo — overnight or term lending against G-Sec collateral at the policy rate (currently 5.25%); (ii) Standing Deposit Facility (SDF) — uncollateralised overnight deposit window at 5.00% (floor); and (iii) Marginal Standing Facility (MSF) — emergency overnight borrowing at 5.50% (ceiling). The corridor between SDF (5.00%) and MSF (5.50%) is 50 basis points; the policy repo rate (5.25%) sits in the middle. If banking system liquidity turns into deficit, banks must borrow from the RBI at the repo rate; large deficits push WACR toward MSF, effectively tightening monetary conditions beyond the policy intent.
- The LAF corridor concept was introduced following the Narasimham Committee recommendations in the late 1990s; the current form dates to 2000
- The SDF replaced the fixed-rate reverse repo as the floor in April 2022
- Variable Rate Repo (VRR) auctions allow the RBI to inject liquidity at market-determined rates within the corridor
- Weighted Average Call Money Rate (WACR) is the RBI's operating target for monetary policy
Connection to this news: The OMO purchases and forex swaps were aimed at keeping WACR near 5.25% (the policy repo rate), preventing a de facto unintended tightening as advance tax and GST outflows temporarily drained banking system liquidity.
Dollar-Rupee Buy-Sell Swap as a Liquidity Tool
A dollar-rupee buy-sell swap involves the RBI purchasing US dollars from banks at the spot rate while simultaneously agreeing to sell them back at a pre-determined forward rate on a specified future date. In the short term, the RBI receives dollars and releases rupees, injecting rupee liquidity into the banking system. The forward leg (when the RBI sells dollars back) re-absorbs liquidity. The premium embedded in the forward leg represents the cost of the liquidity provision and reflects interest rate differentials between India and the US. These swaps serve dual purposes: injecting rupee liquidity and, by absorbing dollar supply, supporting the exchange rate.
- Unlike OMOs, forex swaps do not affect the G-Sec market; they directly address dollar-rupee dynamics
- The RBI has historically used buy-sell swaps in periods of rupee depreciation pressure combined with liquidity deficit
- In the current cycle, a $5 billion buy-sell swap was also announced alongside the OMO purchases
- Such swaps are treated as off-balance-sheet instruments; they do not affect the RBI's net foreign exchange reserves
Connection to this news: The combination of OMOs and forex swaps reflects the RBI's multi-instrument approach to liquidity management — addressing both the rupee liquidity deficit and exchange rate stability simultaneously.
