The Reserve Bank of India’s latest move is a USD‑100 million cap on banks’ net open rupee‑linked forex positions (NOP‑INR) in the onshore deliverable USD/INR market, effective from 10 April 2026. It is not a blanket “USD holding” limit on all dollar balances, but a limit on how much open currency risk banks can carry in INR‑denominated trades.
What the cap is, briefly
Banks must ensure that their Net Open Position in Rupee (NOP‑INR)—i.e., their net exposure to rupee moves via USD/INR trades—does not exceed USD 100 million at the end of each business day.
The cap applies to all authorised dealer banks (onshore deliverable USD/INR market) and replaces the earlier, more flexible system where banks could set their own NOP‑INR limits up to about 25% of capital.
Which banks are most affected
The rule applies to all authorised dealer banks, but the impact is largest on institutions that normally run large open FX books:
Large private banks and foreign banks (e.g., ICICI Bank, HDFC Bank, Axis Bank, Kotak Bank, and major foreign banks such as JPMorgan, HSBC, Citi, Standard Chartered, etc.) that routinely maintain much larger NOP‑INR positions (sometimes up to several hundred million or even close to USD 1 billion across onshore and offshore books) will be hit hardest.
Public sector banks (SBI, PNB, Bank of Baroda, etc.) are also affected, but many of them already tended to keep smaller speculative FX books, so the revenue/strategy impact may be less pronounced than for aggressive private/foreign players.
Practical implication for you (as an investor)
Banks with big FX‑trading franchises may see some compression in trading income as they de‑risk positions and curtail speculative dollar bets.
System‑wide, the cap is meant to reduce rupee volatility and prevent sharp gap‑downs at open, which could be broadly positive for market stability but may also temporarily affect liquidity in USD/INR markets.
If you tell me which specific banks you are tracking (e.g., SBI, HDFC Bank, ICICI, Axis, Kotak, IDFC, etc.), I can sketch a short, bank‑wise view of how this cap is likely to affect their NIMs, opex, and FX‑book economics.
