Nifty Weekly Expiry Today: See What Changed on Sept 1, 2025

Today marks a historic day for traders as the National Stock Exchange (NSE) holds its first-ever Tuesday expiry for all futures and options (F&O) contracts. After 25 years of Thursday being known as “expiry day,” this is a major shift in India’s derivatives market.

The change officially took effect after trading ended on August 28, 2025, and now all contracts (including weekly, monthly, quarterly, and half-yearly) expire on Tuesdays instead of Thursdays. 

No stocks are under F&O ban for the day.

How Have Nifty Weekly Expiry Days Evolved Since 2000?

The NSE began its derivatives journey on June 12, 2000, with the launch of Nifty index futures. These contracts followed a monthly expiry cycle, always ending on the last Thursday. Over time, this Thursday rule applied to most derivatives, including the popular Bank Nifty.

In May 2016, weekly options were introduced for Bank Nifty, also expiring on Thursdays. However, the first major shift came in September 2023, when Bank Nifty weekly expiry moved to Wednesdays. Then in 2025, expiry dates went through multiple changes before the final decision was made.

The big shift happened in May 2025, when SEBI asked all exchanges to use either Tuesday or Thursday as the expiry day. NSE chose Tuesday and rolled out the change in late August.

What It Means for Traders

This change could potentially bring higher volatility on Mondays and Tuesdays for NSE contracts. Most of the time, decay in option prices will now happen over the weekend, so traders must adjust their strategies.

The shift could also mean that traders may use BSE contracts more actively on Wednesdays and Thursdays, especially for expiry-based strategies. This could help balance out trading activity between the two exchanges.

Conclusion

This change marks the start of a new era for NSE traders. While it may take some time to adjust, the move to Tuesday expiry brings new opportunities and challenges. From now on, Monday and Tuesday will become key days to watch in the derivatives market.

So, while Thursday used to be the busiest day, Tuesday is now the new “expiry day” for NSE F&O contracts.
