RBI Defends Rupee at 95.80-96 Per Dollar Level Using Spot Dollar Sales and Swaps

The Reserve Bank of India (RBI) has escalated its intervention across currency and domestic money markets to establish a firm defense line for the rupee between 95.80 and 96 against the US dollar.

Market participants and currency dealers reported that state-run banks stepped in aggressively to sell greenbacks on behalf of the central bank as the spot USD/INR pair hovered near the 95.80 mark. However, the central bank’s most decisive push has unfolded through the derivatives and swap markets, sending significant ripple effects into domestic money-market liquidity.

Multi-Pronged Intervention and Swap Strategy

To absorb external pressure without rapidly depleting headline foreign currency reserves solely in the spot market, the RBI has relied heavily on dollar-rupee sell/buy swaps. Under these swap contracts, the central bank sells dollars and absorbs rupees in the near term, agreeing to reverse the trade at a future maturity.

Key Mechanics of the Central Bank Action:

• Swap Invocations: Traders estimate the RBI conducted January 2027 sell/buy swaps amounting to roughly $1 billion per day across the past 10 trading sessions.
• Liquidity Drain: Combined with open-market operation (OMO) debt sales, the central bank's actions have reduced the banking system's liquidity surplus by approximately 55% from its recent record peak of ₹11.16 trillion.
• Forward Market Pressure: By contracting rupee liquidity, overnight and short-term borrowing costs rise, making it significantly more expensive for currency speculators to fund short positions against the rupee in forward and non-deliverable markets.

Underlying Macro Pressures

The RBI’s intervention comes amid persistent headwinds on India’s balance of payments. International crude prices continue to linger near $100 a barrel, threatening to expand India’s import bill and widen the trade deficit. Meanwhile, global policy divergence has added to the strain following recent rate hikes by both the US Federal Reserve and the Bank of Japan, with CME FedWatch tools pricing a 56% probability of an additional Fed hike in October.

Domestically, inflation concerns have also re-entered the spotlight after India's retail Consumer Price Index (CPI) touched 4.82% in August. Investment bank Natixis has flagged potential monetary tightening, penciling in up to 50 basis points in RBI rate increases by the end of 2026 to curb imported inflation and stabilize the exchange rate.

Implications for Indian Investors

The RBI’s twin approach—capping spot exchange-rate depreciation while draining excess cash from the banking system—shifts immediate market volatility from foreign exchange to domestic debt markets:

Impact Across Asset Classes:

• Bond Yields: As the ₹11.16 trillion liquidity surplus contracts by more than half, short-term money-market instruments, commercial paper, and Treasury bills face upward yield pressure, pushing up funding costs for corporate borrowers.
• Forward Premiums: Corporate importers seeking forward hedges are seeing volatile forward premiums as the interest rate differential and funding squeeze reprice short-dated contracts.
• Equity Sentiment: While the central bank's firm stance prevents abrupt, disorderly depreciation in the rupee, elevated borrowing rates and prolonged high energy prices remain key watchpoints for equity valuations and foreign institutional flows.
