Highlights:

• Understand what F&O expiry day is and how settlement works for index and stock derivatives in Indian markets
• Know the current weekly expiry days in 2026, i.e., Tuesday for Nifty 50 on NSE and Thursday for Sensex on BSE, and how holidays can shift these dates
• Explore expiry-day trading strategies, volatility risks, and risk-management tips to trade options more effectively

Introduction

If you trade in futures and options, expiry days are more than just calendar dates. They can directly influence your profits and risk levels.

In simple terms, the expiry day is the final day a derivatives contract remains active. After this date, the contract is either settled or expires without value.

Understanding how expiry works, especially in the Indian derivatives market, can help you plan trades more effectively, manage risks better, and take advantage of volatility-driven opportunities.

What is an Expiry Day in F&O?

Expiry day is the final trading day for a derivatives contract. After this date, the contract ceases to exist. You must either square off your position before expiry or settle it according to exchange rules.

SEBI regulates these dates to standardise trading across exchanges. Futures and options don’t trade indefinitely; they have fixed lifecycles. Weekly contracts expire every week; monthly contracts expire once per month.

For index derivatives like Nifty 50 or Sensex, expiry means cash settlement; the difference between your contract price and the final settlement price is credited or debited. For stock derivatives, expiry triggers physical delivery; you must deliver or accept actual shares unless you close the position beforehand.

Understanding expiry mechanics prevents surprises. Holding contracts through expiry without adequate funds or shares can trigger penalties and forced liquidations.

F&O Expiry Schedule for 2026

Weekly expiry contracts are now available on only one benchmark index per exchange. Here is the current schedule at a glance:

Bank Nifty, FinNifty, Nifty Midcap Select, Bankex, and Sensex 50 no longer have weekly contracts. They are available as monthly contracts only.

If an expiry day falls on a trading holiday, the expiry moves to the previous trading day. Example: Bakri Id falls on Thursday, 28 May 2026, which is a trading holiday. The Sensex weekly expiry and the BSE monthly expiry for that week move to Wednesday, 27 May 2026.

Why Weekly Expiries Were Reduced to One Index per Exchange

Until late 2024, traders could choose from weekly contracts on multiple indices across the week. That changed with a SEBI circular issued in October 2024, effective 20 November 2024, which allowed each exchange to offer weekly expiry contracts on only one benchmark index.

SEBI introduced this measure to strengthen investor protection and market stability. The regulator observed that the concentration of short-tenor options activity on expiry days was leading to heightened speculation and sharp price swings, which often hurt retail traders.

Following the circular, NSE retained weekly contracts only on Nifty 50, and BSE retained them only on Sensex. In a further change effective 1 September 2025, NSE shifted its Nifty 50 weekly expiry from Thursday to Tuesday, while BSE moved the Sensex weekly expiry to Thursday. This spread expiry activity across the week instead of bunching it on a single day.

What Happens on Expiry Day?

Settlement mechanics vary depending on the type of derivative contract.

Index derivatives are cash-settled. For example, if you hold a Nifty call option until expiry, the settlement is based on the difference between the strike price and the final settlement price, and no actual transfer of shares takes place.

In contrast, stock derivatives are settled through physical delivery. If you hold stock futures until expiry, you must either deliver the shares (for short positions) or take delivery of them (for long positions). Long positions require sufficient funds to purchase the shares, while short positions require the shares to be available in your demat account. Failure to meet these obligations may result in penalties.

Because of these requirements, many traders prefer to square off their positions before expiry to avoid settlement complexities. Physical delivery can involve higher capital commitment and additional charges, whereas cash-settled index derivatives allow smoother exits, as the exchange simply adjusts the net amount in your trading account.

Time-sensitive action: NSE closes regular trading at 3:30 pm. Square off positions before this deadline, or settlement becomes mandatory.

Trading Strategies for Expiry Day

When trading options, many traders prefer to take positions close to expiry day, as this period offers opportunities to apply specific expiry-day trading strategies that aim to benefit from sharp price movements and time decay. With a basic understanding of expiry-day behaviour, traders can participate more confidently in options trading near expiration.

Unlike stock or futures trading, which is typically directional, options trading can be structured using both directional and non-directional strategies. This flexibility allows traders to benefit even when market movements are uncertain, though proper timing and risk control remain important.

Expiry day is usually highly volatile, as contracts approach settlement. Price swings can be sharp and unpredictable, and even technical indicators may generate signals that quickly reverse. As a result, traders may experience sudden gains or losses within short timeframes.

While losses on expiry day are common due to heightened volatility, disciplined traders can also capture significant short-term opportunities. For example, Nifty options on expiry day can sometimes move sharply in premium value depending on where the index is expected to settle.

However, effective risk management is essential. As a general educational guideline, many traders avoid risking more than 2% of their trading capital on a single expiry-day trade. The right limit depends on your own risk profile and capital.

FAQs

1. What is the expiry day for Nifty options?

Nifty 50 weekly options expire every Tuesday, and Nifty 50 monthly contracts expire on the last Tuesday of the month. If the scheduled expiry day is a trading holiday, the contracts expire on the previous trading day. On expiry, out-of-the-money (OTM) options expire worthless, while in-the-money positions are settled in cash.

2. What happens if I hold F&O contracts till expiry?

Index contracts settle in cash. You receive or pay the price difference. Stock contracts undergo physical delivery, requiring full funds or shares in your demat account to avoid penalties.

3. Is it risky to trade on an expiry day?

Yes, trading on expiry day can be risky because the market often experiences high volatility, sharp price movements, and accelerated time decay in options premiums. These factors can increase the chances of losses if trades are not managed carefully. Therefore, expiry-day trading is generally more suitable for experienced traders who follow strict risk management practices, such as using stop-loss orders and maintaining a disciplined trading strategy.

4. What are the current weekly expiry days in India?

Each exchange now offers weekly contracts on only one index. On NSE, Nifty 50 weekly contracts expire every Tuesday. On BSE, Sensex weekly contracts expire every Thursday. No other index has weekly expiries.

5. Why were weekly expiries discontinued for Bank Nifty, FinNifty, and other indices?

SEBI’s October 2024 circular, effective 20 November 2024, restricted weekly expiry contracts to one benchmark index per exchange to curb excessive speculation and protect retail investors. NSE retained Nifty 50, and BSE retained Sensex. Bank Nifty, FinNifty, Nifty Midcap Select, Bankex, and Sensex 50 now trade as monthly contracts only.

6. When do monthly F&O contracts expire?

On NSE, monthly index and stock F&O contracts expire on the last Tuesday of the expiry month. On BSE, Sensex and Bankex monthly contracts expire on the last Thursday of the expiry month. If that day is a trading holiday, expiry moves to the previous trading day.

7. What happens if the expiry day falls on a holiday?

The expiry is advanced to the previous trading day. For example, with Bakri Id falling on Thursday, 28 May 2026, the Sensex weekly expiry for that week moves to Wednesday, 27 May 2026. Exchanges confirm adjusted dates through circulars ahead of each affected month.

8. What is the difference between weekly and monthly expiry?

Weekly contracts expire every week and exist only for Nifty 50 (NSE) and Sensex (BSE). Monthly contracts expire once a month, on the last Tuesday (NSE) or last Thursday (BSE), and are available across indices and individual stocks. Weekly options have lower premiums but faster time decay, while monthly contracts give positions more time to play out.

9. How is the settlement price decided on expiry day?

The final settlement price for index derivatives is based on the average value of the underlying index during the last 30 minutes of trading on expiry day, from 3:00 pm to 3:30 pm. This averaging reduces the impact of any sharp last-minute price moves.

10. Why is the market more volatile on expiry day?

As contracts approach settlement, traders rush to square off, roll over, or adjust positions, which increases volumes and sharp price swings. Accelerated time decay in options premiums and large open interest unwinding near key strike prices add to this volatility.
