With the Indian derivative market rolling into May 2026, market participants enter a new month with new F&O expiry dates. May has 2 major trading holidays, the first one is Maharashtra Day on 1st May and the other one is Bakri Eid on 28th May, which falls on a Thursday, disrupting the regular monthly expiry cycle of the BSE and leading to a one-day preponement of all BSE monthly contracts expiry to Wednesday, 27th May.With the shift of expiry structure of NSE to Tuesdays and BSE on Thursdays, effective from September 2025, it is important for traders to know the exact expiry dates for position management, rollover, and hedging. Since the derivative contracts cannot expire on a trading holiday, May will see its BSE monthly expiry and some MCX commodity contracts adjusted accordingly. Here, we will explore the F&O expiry dates in May 2026 for NSE, BSE, and MCX.What are F&O expiry dates?Expiry date in the derivatives market is the final trading day of a particular futures or options contract. After the market closes on that day, the contract no longer exists. Open positions held by traders can be either:Square off: Close the trade before the market closes to realise the profit or loss and avoid physical or cash settlement complications.Roll over: Exit the current month contract and enter a new position into the next month contract to continue exposure to the market.Let it expire: In options, on expiry, out-of-the-money options are worthless, and in-the-money options are cash-settled or physically delivered, depending on the underlying asset. Some futures contracts are settled at the final closing price, while some are physically settled.Liquidity and volatility tend to increase as expiry dates get closer, with large institutions rolling over positions. Thus, the best strategy to prepare for any sudden market movement would be to monitor the expiry calendar.Important changes for May 2026The May 2026 expiry cycle is interrupted by a weekday trading holiday, the Bakri Eid (Eid al-Adha) on 28th May, Thursday. As the BSE has a Thursday expiry cycle, both the BSE weekly and monthly expiries that would otherwise fall on 28th May are moved forward to Wednesday, 27th May.This does not affect the NSE monthly expiry, which is on the last Tuesday of the month, 26th May. Index expiries in May 2026 (NSE & BSE)After the new structural changes, the NSE follows a Tuesday expiry cycle, and the BSE has a Thursday cycle. Here are the NSE and BSE Index expiries:NSE Index ExpiriesThe NSE index derivatives follow a Tuesday expiry cycle.

The strategic positioning of Bakri Eid on the last Thursday of the month leads to a trading holiday on 28th May and shifts the BSE expiry to Wednesday, 27th May, which leads to NSE and BSE monthly, and several MCX F&O contracts, all expiries closely aligned across consecutive trading sessions.Traders who handle multi-segment derivative books simultaneously should stay vigilant about expiry dates and the settlement cycle to easily navigate the May 2026 expiry season without disruption.
