Indian Banks Suffer ₹4,175 Crore Forex Loss Following Sudden RBI Open Position Restrictions

Reserve Bank of India regulatory changes forced domestic commercial banks to suffer nearly ₹4,175 crore ($500 million) in mark-to-market trading losses on foreign exchange books during the first half of 2026.

According to research published by financial analytics provider Crisil Coalition Greenwich (which takes rupee to dollar value average at 83.50), the substantial trading hit occurred after the central bank imposed strict caps on foreign exchange positions. The Reserve Bank of India issued a directive on 27 March restricting authorised dealer banks to an end-of-day onshore rupee net open position cap of ₹835 crore ($100 million).

Tight Ten-Day Unwinding Window Triggers Market Disruption

Lenders were required to liquidate non-compliant positions by 10 April, triggering a frantic adjustment across bank dealing desks. The brief ten-day compliance window coincided with heightened global volatility, substantial foreign portfolio outflows, and heavy corporate demand for currency hedging contracts.

"The short implementation window for the new RBI rules forced banks to unwind or rebalance positions quickly at a time of elevated rupee volatility, foreign-investor outflows and heavy corporate hedging demand," said Nitin Agicha, Vice President of Market Structure and Technology at Crisil Coalition Greenwich.

The tight limits constrained the capacity of commercial banks to warehouse foreign exchange risks and supply currency liquidity to commercial importers. Concurrently, restrictions placed on related-party derivative transactions limited the ability of treasury desks to offset risk exposures across international subsidiaries.

Banks Recoup ₹3,340 Crore as Market Spreads Widen

Treasury desks managed to recoup approximately ₹3,340 crore ($400 million) of the initial losses later in the period as bid-ask spreads widened and positions normalized. Dealers adapted to the regulatory environment by pricing in higher execution risks and reduced balance-sheet capacity.

Recognising the severe operational pressures on institutional balance sheets, the central bank stepped in on 20 April to withdraw select operational instructions and permit limited exceptions for related-party transactions.

"First-half losses in FX were not simply the result of weaker client activity, but a short-term flip in trading due to RBI direction," said Aamir Hazaria, Director of Corporate and Investment Bank Competitor Research and Analytics at Crisil Coalition Greenwich.

Rising Energy Import Bills Compound Currency Strain

Macroeconomic pressures continue to complicate currency market dynamics, with surging crude oil import bills emerging as a major source of rupee weakness. India remains structurally exposed to energy market volatility, importing nearly 85% of its crude oil requirements and 50% of its natural gas needs.

Official data highlights that India's energy import bill jumped 20% between January and July 2026. Total monthly imports scaled ₹8.01 lakh crore ($95.9 billion) during the period, marking the highest level recorded since 2011.

The long-term stability of the domestic currency remains tied to international trade developments and global risk sentiment. While central bank interventions have suppressed extreme currency swings, the overall strength of the rupee will depend on foreign capital inflows and the capability of the country to manage its massive energy import bill.
