RBI Conducts At Least $10 Billion In Currency Swaps To Drain Surplus Banking Liquidity

In an effort to tackle an unprecedented cash overhang, the Reserve Bank of India (RBI) has conducted dollar-rupee sell-buy swaps amounting to at least $10 billion over the past few weeks. The bilateral transactions with commercial banks feature contract maturities ranging from one month to around six months, marking an expanded use of foreign-exchange operations for domestic liquidity management.

The scale of the intervention is substantially larger than the RBI's standard public swap auctions, which have historically operated in tranches of $3 billion to $5 billion. Market economists estimate that total sell-buy swaps maturing within the current fiscal year could range between $10 billion and $15 billion.

Inflows Trigger Record Liquidity Glut

The urgent need to drain funds follows an immense accumulation of cash in the banking system. Regulatory measures introduced earlier this year to attract foreign capital generated over $140 billion in foreign currency inflows, largely through Foreign Currency Non-Resident (Bank), or FCNR(B), deposits.

The sheer magnitude of these foreign inflows pushed banking system surplus liquidity to a historic peak of approximately ₹11 lakh crore (around $115 billion) earlier this month. This sudden liquidity overhang posed twin risks:

• Excessive downward pressure on money market borrowing rates, pulling them below the repo corridor.
• Latent inflation risks amplified by elevated global crude oil prices and unchecked domestic credit expansion.

Through sell-buy swaps, the central bank sells US dollars to banks against rupees, taking rupees out of circulation with an agreement to reverse the trade at a pre-determined date. This mechanism allows the RBI to temporarily absorb rupee cash without permanently reducing its headline foreign exchange reserves.

Market Impact and Yield Response

The aggressive operations have had an immediate impact on forward premia and domestic money markets. Forward rates on dollar-rupee contracts maturing in three to six months have risen sharply, with six-month and one-year forward premia jumping roughly 20 basis points to their highest levels since May.

According to Gaura Sen Gupta, Chief Economist at IDFC FIRST Bank, the central bank's active deployment of bond sales and sell-buy swaps prevented systemic cash surplus from reaching an estimated peak of ₹15.5 trillion.

Combined with open market bond sales, the swaps have already curtailed the banking system's surplus liquidity by roughly 55% from its peak, bringing the surplus down to ₹4.92 trillion. The continued liquidity recalibration signals that the RBI intends to keep financial conditions closely aligned with its monetary policy stance to anchor retail inflation firmly to its medium-term targets.
