Stocks Under F&O Ban on Nifty’s Weekly Expiry Day

Ahead of the Nifty’s weekly expiry on December 16, 2025, the National Stock Exchange (NSE) has placed one stock under the Futures and Options (F&O) trading ban.

This restriction is triggered when the open interest in a stock’s derivative contracts exceeds 95% of the Market-Wide Position Limit (MWPL). While new derivative positions are prohibited, trading in the cash market continues as usual.

Stocks under the F&O ban for December 16

Bandhan Bank Limited

As of December 15, 2025, Bandhan Bank Limited’s share price ended higher in the cash market. 

The stock opened at ₹149.10 against a previous close of ₹149.57 and moved within a day’s range of ₹148.01 to ₹152.20.

It eventually closed at ₹151.79, while the last traded price stood at ₹151.45, marking a gain of ₹1.88 or 1.26% for the session.

Why Is a Stock Under F&O Ban?

A stock is placed under the Futures & Options (F&O) ban by the NSE when the open interest in its derivative contracts exceeds 95% of the Market-Wide Position Limit (MWPL).

The objective of this regulatory measure is to curb excessive speculation and maintain orderly market conditions, particularly during expiry sessions.

During the ban period:

• No new F&O positions are allowed in the stock.
• Traders may only square off or reduce existing positions.
• Any violation of the ban rules may result in financial penalties or disciplinary action by the exchange.
