RBI Caps Bank Forex Positions at $100 Million — Why Banks Crashed

RBI's Boldest Forex Move in a Decade

The Reserve Bank of India dropped a bombshell on the forex market. In a circular issued on March 27, the RBI directed all authorised dealer banks to ensure their net open position in rupee (NOP-INR) in the onshore deliverable market does not exceed $100 million at the end of each business day. Full compliance is required by April 10, 2026.

Bloomberg called it India's most forceful currency intervention step in over a decade. The result? Bank Nifty crashed 3.82% in a single session, and the rupee saw immediate relief — bouncing from a record low of 94.84 to 93.59 against the dollar.

What Changed Exactly?

Previously, banks' open forex positions were capped at 25% of their total capital. For large banks, this meant they could hold billions of dollars in one-sided bets. The new rule replaces this with a flat $100 million absolute cap — regardless of bank size.

Parameter	Old Rule	New Rule
Cap type	25% of capital	Flat $100 million
Effective	Existing	April 10, 2026
Impact on large banks	Could hold $2-5 billion	Max $100 million
Rupee speculation	Easy to build large bets	Severely restricted

Why Did RBI Do This?

The rupee has been under intense pressure:

• Rupee hit 94.84/$ — an all-time record low
• 4% decline this year against the dollar (after 4.7% fall in 2025)
• Brent crude above $108 — India imports 85% of its oil
• FPI outflows of ₹1.13 lakh crore in March alone
• US-Iran war disrupting global energy markets

The RBI's move is designed to stop banks from building large speculative positions against the rupee. By forcing them to limit exposure, the central bank reduces the market's ability to pile on one-way bets.

Why Bank Stocks Crashed

Market estimates suggest that banks currently hold around $40 billion in long-dollar positions that will need to be squared off before April 10. This forced unwinding means:

• Mark-to-market losses for banks as they close positions
• Reduced forex trading revenue going forward
• Uncertainty about profitability in the forex desk operations

Banks have already urged the RBI to revisit the cap, flagging concerns about MTM losses and forced unwinding. Whether the RBI eases the deadline remains to be seen.

What It Means for You

If you're a regular saver or investor, this RBI move is actually positive for you:

• Rupee stability means less imported inflation (cheaper petrol, electronics, cooking oil)
• Lower volatility in currency markets reduces uncertainty for businesses
• If you hold bank stocks — expect short-term pain but the structural impact is limited. Forex trading is a small part of most banks' total income
