RBI Absorbs Record 11 Trillion Rupee Liquidity Surplus Using Bond-Sparing Foreign Exchange Swaps

The Reserve Bank of India (RBI) has turned to the foreign exchange market to manage an unprecedented cash glut in the financial system, deploying short-term sell-buy foreign exchange (FX) swaps. The move is aimed at draining a record domestic liquidity surplus estimated at around ₹11 trillion (approximately $115 billion) without disrupting the domestic sovereign bond market.

The massive buildup in rupee liquidity followed a surge in overseas foreign-currency inflows. Under recent special deposit mobilization programs, Indian lenders raised over $136 billion—led heavily by Foreign Currency Non-Resident (Bank), or FCNR(B), deposits—and subsequently swapped these dollar inflows with the central bank for rupees. While the inflows fortified India's external buffers and forex reserves, the conversion flooded domestic banks with excess cash, dragging the weighted average call-money rate below the policy repo rate and raising concerns about monetary policy transmission and inflation risks.

Mechanism of the Sell-Buy FX Swaps

Under a sell-buy swap structure, the central bank sells US dollars to commercial banks in the spot market against rupees, immediately mopping up rupee liquidity from the banking system. The RBI concurrently enters into a forward contract agreeing to buy the dollars back at a later date, with several contracts maturing in October.

This foreign-exchange strategy offers critical advantages over conventional liquidity absorption tools:

• Sparing the Bond Market: Open Market Operations (OMO) involving direct sales of government securities would have exerted sharp upward pressure on sovereign bond yields, raising borrowing costs for both the government and corporate issuers.
• Protecting Bank Margins: Avoiding an immediate increase in the Cash Reserve Ratio (CRR) allows commercial lenders to maintain their net interest margins without impounding unremunerated reserves.
• Managing the Forward Book: The swaps help the RBI manage its outstanding forward dollar obligations maturing over the coming months.

Market Impact and Forward Premia Reaction

The central bank's swap operations immediately resonated across money and currency markets. Near-term dollar-rupee forward yields climbed sharply, with the three-month onshore forward yield jumping 23 basis points to 3%, while six-month forward yields rose by 15 basis points.

The higher forward premia increase the cost of currency hedging for dollar-based foreign portfolio investors and domestic importers, while making carry-trade operations more nuanced.

Complementary Liquidity Operations

The FX swap intervention follows aggressive variable-rate reverse repo (VRRR) operations conducted by the central bank to manage daily balances. The RBI recently offered a ₹7 trillion, 30-day VRRR auction alongside daily overnight reverse repo auctions absorbing trillions of rupees, indicating a multi-pronged approach to keeping overnight money market rates closely aligned with the policy benchmark.

Economists note that while sell-buy swaps push liquidity absorption down the road rather than extinguishing it permanently, they provide the central bank with essential flexibility to sterilize bulky inflows while maintaining stability across Indian equity, bond, and credit markets.
