RBI Bond Sales and FX Intervention Cut India's Liquidity Surplus by 55% to ₹4.92 Trillion

Aggressive and sustained intervention by the Reserve Bank of India (RBI) has more than halved the banking system's cash surplus, reigning in an unprecedented liquidity overhang that threatened to fuel domestic inflationary pressures.

Surplus banking system liquidity dropped to ₹4.92 trillion ($51.36 billion), marking a 55% drop from the historic peak of ₹11.16 trillion recorded earlier in the month. The temporary liquidity buildup had been triggered after domestic lenders mobilised a higher-than-anticipated $133 billion through the central bank’s diaspora deposit framework.

Faced with a deluge of surplus cash alongside currency volatility and high global crude oil prices, RBI Governor Sanjay Malhotra signalled that the central bank would deploy durable measures, including open-market operations (OMOs) and foreign exchange tools, to anchor overnight borrowing rates near the policy benchmark.

Key Drivers of the Cash Drain

The reduction in surplus funds was steered by a coordinated set of market operations and seasonal cash outflows:

• Open Market Bond Sales: The central bank conducted auction-based sales of sovereign securities maturing between fiscal 2029 and fiscal 2032, draining ₹750 billion from the banking system across recent auctions as part of an intended ₹1 trillion OMO programme.
• Foreign Exchange Interventions: To defend the rupee and absorb cash, the RBI engaged in foreign exchange sales and sell-buy swaps. Money market dealers estimated the central bank absorbed liquidity via FX swaps amounting to roughly $1 billion per day over ten consecutive trading sessions.
• Statutory Tax Outflows: Corporate advance tax payments and Goods and Services Tax (GST) remittances pulled significant cash reserves out of commercial bank balances into government accounts.
• Reverse Repo Operations: Commercial banks deployed substantial excess balances back with the central bank, parking approximately ₹3.4 trillion under variable rate reverse repo (VRRR) windows.

Impact on Debt Markets and Borrowing Costs

The aggressive draining of durable liquidity has rapidly transmitted through the domestic fixed-income market. Yields on shorter- and intermediate-dated government securities have hardened significantly, causing a bear-flattening of the yield curve. Yields on five-year government bonds climbed toward 6.83%, while the 10-year benchmark yield traded higher as debt supply expanded from RBI portfolio sales.

For Indian banks and corporate issuers, the removal of the liquidity overhang signals an end to ultra-low short-term money market rates. As liquidity tightens toward neutral-to-balanced levels, short-term commercial paper and certificate of deposit rates are firming up, ensuring monetary policy transmission remains intact ahead of upcoming policy decisions.
