The Nifty weekly derivatives contracts are scheduled to expire on Tuesday, September 30, 2025, in line with the standard weekly cycle. Caution ahead of expiry has resulted in tempered market sentiment.
Ahead of the Nifty’s weekly expiry on Tuesday, September 30, 2025, the National Stock Exchange (NSE) has placed 2 stocks under the Futures and Options (F&O) trading ban:
This restriction is enforced when the open interest in the stock crosses 95% of the market-wide position limit (MWPL). While fresh derivative positions are disallowed, the stock continues to be available for trading in the cash market.
The stocks under the F&O ban for September 30 are:

A stock is placed under the F&O ban list when open interest exceeds 95% of MWPL, as per NSE guidelines.
During the ban:
This safeguard is meant to curb speculation and ensure orderly market function during high-activity periods like expiry days.
The Nifty 50 F&O contracts expire every Tuesday, unless it’s a trading holiday (in which case, expiry moves to the prior session). Settlements occur at the day’s closing price.
For ease of tracking, expiry contracts may appear under the monthly header on trading platforms during expiry week.
