RBI's $100 Million Net Open Position Cap: What It Means for Banks, the Rupee, and Borrowers

In late March 2026, the Reserve Bank of India directed all banks operating in India to ensure that their net open position in the onshore deliverable foreign exchange market does not exceed $100 million at the end of each business day, with a compliance deadline of April 10, 2026. The direction marks the first time since 2011 that the RBI has explicitly set a hard ceiling on how much currency risk a bank can carry in the onshore market. The move has triggered significant market reactions, forcing banks to unwind large long-dollar positions and creating sharp short-term volatility in the rupee.

The Previous Framework and What Has Changed

Under the framework in place before this directive, banks could maintain net open positions of up to 25 percent of their tier-1 capital, measured across their onshore spot and forward markets, non-deliverable forwards, and currency futures. This gave large banks considerable room to build substantial proprietary currency positions. The RBI's new $100 million hard cap replaces that percentage-based framework for onshore deliverable positions with a fixed absolute limit, regardless of the bank's capital size. A large private sector bank with significant tier-1 capital that previously could hold hundreds of millions of dollars in open currency exposure will now be capped at $100 million. Market estimates suggest that as much as $30 to $40 billion of aggregate long-dollar positions held by Indian banks may need to be unwound before the April 10 deadline.

Why the RBI Has Acted: Rupee Pressure and Market Context

The directive comes against a backdrop of mounting pressure on the Indian rupee, driven by a combination of rising global oil prices and heavy foreign portfolio investor outflows from Indian equity and debt markets. Many Indian banks had accumulated large long-dollar and short-rupee positions, partly through proprietary trading and partly through arbitrage between onshore and offshore markets. These positions, while profitable when the rupee weakens, have the effect of amplifying rupee depreciation pressure during periods of stress, as banks collectively bet against the domestic currency. The RBI's directive is designed to dismantle these structural positions and reduce the ability of banks' proprietary desks to exacerbate currency weakness.

Banks' Response: Seeking More Time

Several major banks have formally approached the RBI requesting a three-month extension to the April 10 compliance deadline. Their concern is that forced unwinding of large positions within a short window could itself trigger disorderly market conditions, sharp mark-to-market losses on existing positions, and adverse impacts on hedging arrangements that their corporate clients have entered into. The Bank Nifty fell by over four percent following the RBI's announcement, reflecting market concern about the implications for bank profitability. The RBI has not confirmed whether it will grant any extension. Banks that cannot comply by April 10 without breaching market stability should document their compliance efforts carefully to demonstrate good faith in the event of regulatory scrutiny.

Implications for Corporates and Importers

The position cap affects not only bank proprietary trading desks but also the hedging market that Indian corporates depend on to manage currency exposure. As banks reduce their own open positions, the cost and availability of forward contracts and options for Indian importers, exporters, and borrowers with foreign currency loans could be affected. Importers who rely on forward covers to lock in dollar purchase rates, and exporters who hedge their receivables, should monitor the situation closely over the April 10 deadline period. Corporate treasury teams should also review their outstanding hedging contracts to assess any potential counterparty exposure if a bank significantly restructures its forex book.

Practical Takeaways

For banks, compliance with the April 10 directive is mandatory and non-negotiable absent any RBI extension. Treasury and risk management teams should immediately calculate current net open positions across all onshore deliverable instruments and develop a structured unwinding plan. For corporate borrowers and treasury functions, the near-term period to April 10 may bring unusual rupee volatility and potential changes in hedging costs, which should be factored into treasury planning. For legal practitioners advising financial institutions, the RBI's direction raises important questions about the interaction between the new cap and existing contractual hedging obligations, and whether any bank's compliance steps could constitute a breach of forward contract obligations to clients. Clients with active forex litigation or regulatory matters before the RBI should take note of this development as relevant context.
