SEBI to announce final decision on equity derivatives expiry days today

The Securities and Exchange Board of India (SEBI) is expected to release its final circular today regarding the allotment of expiry days for equity derivatives contracts across stock exchanges. This move follows a consultation process initiated in March 2025, aiming to streamline expiry schedules and reduce market volatility.

As previously reported by CNBC-TV18 on May 22, SEBI had proposed that all equity derivatives contracts be limited to expiries on either Tuesdays or Thursdays. This proposal was in response to concerns over excessive speculative trading on multiple expiry days throughout the week. The deadline for exchanges to submit their applications for preferred expiry days was June 15, 2025.

According to sources, the National Stock Exchange (NSE) has applied for Tuesday as its designated expiry day.
The final SEBI circular is anticipated to formalise these changes, providing clarity on the uniform expiry schedule and its implementation across exchanges. Market participants are awaiting this announcement to adjust their trading strategies accordingly.
