Banking stocks opened sharply lower on Monday, 30 March 2026. This follows the Reserve Bank of India's tightening of rules to stabilize the rupee against the US dollar. The Bank Nifty index fell over 2% in early trade, with every constituent in the red.
Axis Bank, IndusInd Bank, Kotak Mahindra Bank, IDFC First Bank, and Yes Bank led the decline, slipping 2–3% as investors reacted to the central bank’s latest directive.
The RBI on March 27, 2026, asked banks to cap their net open rupee (NOP-INR) positions in the onshore foreign exchange market at $100 million at the end of each business day. Banks must comply at the earliest, with a hard deadline of April 10, 2026.
Earlier, lenders could offset positions across onshore markets, non-deliverable forwards (NDF), and currency futures, with limits stretching up to 25% of capital. The new rule isolates onshore exposure and sharply reduces flexibility.
The tighter cap forces banks to unwind large arbitrage positions built between onshore and offshore markets. Analysts estimate these trades at $10–18 billion, with total outstanding bets possibly nearing $40 billion.
Many banks reportedly hold long dollar positions and short rupee exposure in proprietary books. The new rule compels them to sell dollars in the onshore market and rebalance positions elsewhere.
Systematix noted that such adjustments could widen spreads between markets and erase earlier arbitrage gains, potentially turning them into losses.

Forced selling of the dollar will add to supply in the domestic market, supporting the rupee in the near term. The action reflects the RBI’s commitment to controlling speculative NDF arbitrage and volatility as the rupee nears the 95 mark against the dollar.
Banking and financial institutions that have significant treasury and forex operations, such as State Bank of India, HDFC Bank, ICICI Bank, and Axis Bank, are most likely impacted. However, bank-wise positions are not disclosed, and investors are advised to be cautious.
This is clearly seen in the way the markets are reacting to the situation. Treasury losses, tightened trading limits, and margin pressure are all on investors’ minds.
