Share Market Expiry Days in India 2026: Complete Guide

If you trade in futures & options (F&O), expiry days are not just dates; they directly affect your profits and risks.

In simple terms, the expiry day is the last trading day of a derivative contract. After this, the contract is settled, exercised if applicable, or an option may expire with no value if it finishes out of the money.

Understanding how expiry works, especially in Indian markets, helps you plan better trades, avoid unexpected settlement obligations, and manage the faster option time decay that can occur near expiry.

As of October 2026, Nifty 50 weekly options expire on Tuesdays on the National Stock Exchange (NSE), while Sensex weekly options expire on Thursdays on BSE. Bank Nifty, FINNIFTY, and Nifty Midcap Select do not have weekly expiries.

The Basics of Share Market Expiry Days

Expiry mainly applies to derivatives such as futures & options. Each contract has a fixed expiry date. If you hold it until expiry:

• An out-of-the-money option can expire with no intrinsic value.
• Index derivatives are cash-settled.
• Stock derivatives can create physical delivery obligations.

If the scheduled expiry is a trading holiday, it generally moves to the previous trading day.

Understanding Weekly Expiry in Indian Markets

Weekly expiries are now limited. Securities and Exchange Board of India (SEBI) rules allow each exchange one weekly benchmark index options contract.

Weekly Expiry Schedule in India

Index	Exchange	Weekly expiry in 2026
Nifty 50	NSE	Tuesday
Sensex	BSE	Thursday
Bank Nifty	NSE	No weekly expiry
FINNIFTY	NSE	No weekly expiry
Nifty Midcap Select	NSE	No weekly expiry

The Significance of Expiry Days for Traders

Expiry matters because it can affect option premiums, trading activity, and margin requirements. As expiry approaches, an option’s remaining time value declines. This decay is measured by theta. Short-dated options can lose time value quickly, although the effect varies by strike and market conditions.

On expiry day, traders holding short option positions face an additional 2% Extreme Loss Margin (ELM), which increases the margin required for those positions.

Revised Nifty 50 and Bank Nifty Expiry Day

The current schedule differs sharply from the older pattern many traders may remember:

• Nifty 50 weekly options expire on Tuesday.
• Nifty 50 monthly contracts expire on the last Tuesday.
• Bank Nifty has no weekly options. Its monthly and quarterly contracts expire on the last Tuesday.
• FINNIFTY and Nifty Midcap Select have monthly contracts expiring on the last Tuesday.

Impact of Expiry Days on Market Volatility

Expiry can bring sharp moves, but volatility is not guaranteed to rise every time. Position unwinding, hedging, and movement in the underlying can all affect price action. Treat expiry as a period of changing risk, not a predictable source of profit.

How Expiry Days Affect Your Trading Strategy

Near expiry:

• Examine how much time value remains.
• Review margin and settlement obligations.
• Do not assume premium decay or a price move will continue.

During the expiry session, use predefined entry, exit, and risk limits, and check liquidity and bid-ask spreads before trading.

Adjusting Your Positions Before Expiry

Before expiry, traders may square off positions, roll futures into a later contract, hedge risk, or close stock-derivative positions to avoid physical settlement obligations. Rolling changes the contract month, but does not remove market risk.

Strategies for Expiry Day Movements

Common approaches include:

1. Option selling: May benefit from time decay, but naked short options can carry large losses.
2. Intraday breakout trading: Seeks moves beyond technical levels, but false breakouts are possible.
3. Iron condor: A limited-risk structure generally used when a trader expects the underlying to remain within a range.
4. Long straddle or strangle: Can benefit from a sufficiently large move in either direction, but it loses value if the move is too small relative to the premium paid.

Choose a strategy based on market conditions, liquidity, position size, and a predefined maximum loss.

Understanding Investment Risks and Risk Tolerance

Expiry trading can involve leverage, fast losses, margin changes, and settlement risk. Before trading, ask whether you understand the settlement outcome, can absorb the maximum loss, and have a clear exit rule.

If not, avoiding aggressive expiry-day strategies may be the more prudent choice.
