Indian banks pitch FX sell/buy swaps to drain surplus liquidity, sources say

The recent proposal by Indian banks to the Reserve Bank of India (RBI) for conducting foreign exchange (forex) sell/buy swaps marks a significant moment in India's liquidity management framework. To understand this development, we must first appreciate the context: India's banking system has been awash with surplus rupee liquidity, which touched record highs in early 2024. This surge was primarily driven by substantial foreign currency deposits, particularly from non-resident Indians (NRIs) under schemes like FCNR (B) — Foreign Currency Non-Resident (Banks) deposits — and robust capital inflows. When foreign currency enters the banking system, banks typically convert it into rupees, expanding domestic liquidity. While ample liquidity supports credit growth, excessive surplus can destabilize short-term interest rates, pushing them below the RBI's policy repo rate, thereby weakening monetary policy transmission. The sell/buy swap mechanism proposed by banks is a well-established tool in the RBI's arsenal. In a sell/buy swap, banks sell dollars to the RBI in exchange for rupees (spot leg), agreeing to repurchase the dollars at a predetermined rate on a future date (forward leg). This temporarily drains rupee liquidity from the system without permanently reducing foreign exchange reserves. Crucially, unlike open market operations (OMOs) involving outright sale of government securities — which can harden bond yields and hurt bank margins — or increasing the Cash Reserve Ratio (CRR), which directly reduces lendable resources and compresses net interest margins (NIMs), the swap mechanism is margin-neutral. Banks earn a swap premium (the difference between spot and forward rates), which often aligns with market interest rate differentials, preserving profitability. The meeting between bank representatives and the RBI underscores the consultative approach of India's central bank in monetary management. Under the RBI Act, 1934, particularly Sections 45W and 45U, the central bank is empowered to regulate money market instruments and conduct repo/reverse repo operations. The RBI's liquidity management framework, formalized under the Liquidity Adjustment Facility (LAF) introduced in 2000 and refined over time, includes tools like variable rate reverse repo (VRRR) auctions, standing deposit facility (SDF), and forex swaps. The fact that banks proactively suggested this tool reflects their confidence in its efficacy and their desire to avoid measures like CRR hikes — last used in May 2022 — which directly impinge on lending capacity. This episode connects to broader themes in Indian economic governance: the delicate balance between exchange rate stability, monetary autonomy, and financial sector health. India's managed float exchange rate regime, guided by the RBI's intervention to prevent excessive volatility, often leads to liquidity surges when capital flows are strong. The use of forex swaps for liquidity management is not new — the RBI conducted large-scale dollar-rupee swaps in 2019 and 2022 — but the current proposal highlights institutional maturity where market participants co-create solutions. It also reflects the growing sophistication of India's financial markets, where banks understand the implications of various sterilization tools on their balance sheets. Looking ahead, the RBI's response will signal its assessment of liquidity conditions. If the surplus is deemed structural — driven by sustained capital inflows — the central bank may prefer longer-tenor swaps or even consider OMOs. However, with the RBI projecting GDP growth of 7% for FY25 and inflation trending toward the 4% target, premature tightening could be counterproductive. The Monetary Policy Committee (MPC), constituted under the amended RBI Act, 1934 (via Finance Act, 2016), will monitor liquidity's impact on the weighted average call rate (WACR), the operating target of monetary policy. For aspirants, this episode is a live case study in central banking: how tools are selected not just for efficacy, but for distributional consequences across the financial system. It reinforces that modern monetary policy is as much about institutional coordination as it is about economic theory.
