RBI Conducts Over $10 Billion in FX Swaps to Drain Surplus Banking System Liquidity

The Reserve Bank of India (RBI) has conducted foreign-exchange swap operations worth at least $10 billion in recent weeks to absorb excess liquidity from the domestic financial system. The central bank used sell-buy currency swaps to sterilize surplus cash and contain potential inflationary pressures resulting from an unprecedented liquidity buildup.

Under the sell-buy swap mechanism, the RBI sells US dollars to commercial banks in exchange for Indian rupees while simultaneously agreeing to repurchase the foreign currency at a predetermined future date. This arrangement removes rupees from circulation during the tenor of the swap without permanently depleting the country's foreign exchange reserves or putting excessive upward pressure on sovereign bond yields.

Drivers of the Massive Liquidity Overhang

The banking system had experienced an influx of liquidity following robust foreign capital inflows and central bank market interventions, which pushed system surplus cash to an all-time peak of approximately ₹11.16 trillion ($115 billion) in early September.

Key factors behind the RBI's aggressive liquidity absorption include:

• Inflation Management: Prolonged surplus liquidity in the banking system risks driving interbank call rates well below policy benchmarks, easing financial conditions faster than intended and posing upside risks to headline inflation.
• Sterilization of Inflows: The central bank opted for FX swaps alongside government bond sales to sterilize large inflows without overburdening the domestic debt market.
• Currency Stability: Conducting sell-buy operations assists in navigating currency volatility, providing dollar supply in the forward and spot markets while defending the rupee against external headwinds.

Impact on Banking Liquidity and Money Markets

Central bank interventions through currency swaps, open market bond sales, and spot market operations have already reduced the surplus cash pool considerably. The banking system's liquidity surplus declined by roughly 60% from its record high, dropping to ₹4.44 trillion ($46.38 billion).

What It Means for Investors and Markets

For debt market participants, the use of FX swaps offers temporary relief by diversifying the instruments used for liquidity withdrawal. Relying solely on Open Market Operation (OMO) bond sales could have led to a sharp spike in sovereign bond yields. However, the large volume of swaps can influence forward premia, raising hedging costs for corporate borrowers and importers.

In the equity and banking sectors, a normalized liquidity framework ensures disciplined credit growth and prevents speculative misallocation of funds. Investors can expect money market rates and short-term debt instruments, such as treasury bills and commercial paper, to remain closely aligned with the RBI's benchmark repo rate as the central bank maintains an active liquidity management stance.
