The Reserve Financial institution of India’s (RBI) emergency intervention to arrest the rupee’s freefall amid the Iran warfare has arrange a possible Rs 4,000 crore hit to the banking sector, as lenders race to unwind billions of {dollars} in arbitrage positions earlier than an April 10 deadline.

The rupee rebounded practically 1% to 93.85 per greenback on Monday after the RBI capped banks’ web open positions at $100 million on the finish of every enterprise day, a dramatic tightening that forces lenders to dismantle massive one-sided bets towards the forex. However the banking sector paid an instantaneous worth.

Nifty Financial institution tumbled 2.5%, with Axis, Kotak, and IndusInd Financial institution main losses with 3% declines, whereas ICICI, HDFC Financial institution, and SBI fell round 2% every.

The directive comes because the rupee has depreciated roughly 10% this fiscal yr and three.5% because the Gulf battle started, falling from 85.57 per greenback on April 1, 2025, to 90.98 by February 27, a day earlier than the warfare began, finally hitting a report low of 94.84 final Friday.

The Mechanics of Ache

The potential losses stem from how banks had structured their overseas trade operations. Lenders constructed substantial arbitrage positions by shopping for {dollars} within the onshore market at decrease premiums and promoting them within the offshore non-deliverable forwards market at greater premiums, exploiting the unfold between the 2 segments. The scale of such positions is estimated at $25 billion to over $50 billion, in accordance with Reuters.
“We perceive that the foreign exchange by-product market is dominated by bigger banks (Indian banks like SBI, ICICI, HDFC, Axis, and main overseas banks working in India) with gross onshore positions of $30-40bn that offset one another,” wrote Prakhar Sharma and Vinayak Agarwal of Jefferies. “The conventional commerce is for banks to purchase USD within the onshore market (at a decrease premium) and promote/ sq. off within the offshore market (at a better premium) to generate a variety and construct depth available in the market.”
The analysts warned that unwinding these positions might set off mark-to-market losses within the fourth quarter. “Each Rs1/USD twin motion in INR on $30-40 bn of guide can result in a one-time lack of Rs 30-40 bn (Rs 3,000-4,000 crore) for the banking sector,” they famous. If the hole between rupee-dollar charges within the NDF market and the onshore market widens to Re 1 throughout unwinding, merchants mentioned banks might face losses of as much as Rs 4,000 crore, mirrored in present fiscal yr books, as banks had calculated open positions after netting off hedged NDF trades.

Why the RBI Acted

The central financial institution’s intervention comes amid intense stress on the rupee from a number of fronts. The forex has tumbled by means of key psychological ranges in fast succession, pressured by surging crude oil costs and considerations that the Gulf warfare could not finish quickly.

The unfold between offshore and onshore markets had widened considerably amid heightened volatility and threat aversion tied to oil-driven pressures linked to the Iran warfare.

“The measure compels lenders to cut back massive positions and curbs their skill to construct aggressive one-sided bets towards the rupee,” mentioned Jigar Trivedi, Senior Analysis Analyst at IndusInd Securities. “The intervention comes because the rupee has declined greater than 4% over the previous month, falling to round 94.82 per US greenback. Stress has been compounded by sustained capital outflows, together with over $11 billion withdrawn from Indian equities and report bond outflows of $1.6 billion in March, additional weakening demand for the forex.”

Banks search reduction

The banking sector has sought leniency from the RBI on implementation. “Our conversations with banks point out that the RBI is contemplating some reduction, which can embrace grandfathering current contracts and making use of limits solely to new contracts,” Jefferies analysts wrote. “It could additionally take into account extending the deadline past April 10 to permit for smoother foreign exchange market motion and scale back MTM affect on banks.”

Most massive and mid-sized banks with web open positions exceeding $100 million are anticipated to promote {dollars} to adjust to the directive, probably triggering a wave of onshore greenback promoting as they rush to unwind arbitrage positions.

Not everybody views the potential losses as catastrophic. Fund supervisor Samir Arora provided a contrarian take: “Simply loosen up about this supposed Rs 4,000 crore loss on FX unwinding. In simply the previous month, the INR has depreciated by over 4%. These positions wouldn’t have been arrange for the primary time at Friday’s shut. Banks could be sitting on vital positive aspects by now (which fairness markets could not have totally priced in), and they’re going to merely surrender a few of these earnings. Huge deal.”

Arora additionally recommended the affect could also be concentrated elsewhere: “A few of the bigger positions could have been taken by extra aggressive overseas banks (like Citi, and so forth.). That’s not a serious concern for our markets.”

The street forward

Whereas the RBI’s transfer could present momentary help to the rupee, merchants stay cautious in regards to the forex’s trajectory. If the West Asia battle persists and crude oil costs stay elevated, the main focus might rapidly shift again to the 96–97 per US greenback vary in April as the following stress zone, merchants warned.

The unwinding might also create winners. Appreciation of the rupee within the NDF market might result in positive aspects for hedge funds and overseas banks in foreign exchange derivatives, Jefferies analysts famous.

For now, the central financial institution has purchased respiration room for the rupee, however at a value the banking sector is prone to bear in its This autumn earnings.
