When an Indian exchange excludes a stock from its futures and options (F&O) segment, it normally stops listing contracts for new expiry months first. Futures and options that are already listed and have not expired can usually continue trading until their specified expiries, and the exchange may add strikes within those existing contract months. After the final listed expiry or date in the exchange notice, no F&O contract in that stock remains available on the exchange.
The exact timetable is security-specific. Read the latest exchange circular for the stock: it identifies the remaining expiry months, the final trading date and any exceptional action. Exclusion is not the same as a temporary F&O ban, which is a position-limit restriction allowing only trades that reduce open interest.
What changes on the exclusion date?
An exclusion is generally a phase-out of listed derivatives rather than an instant cancellation of every contract. The exchange stops issuing a fresh month contract on the stock. Existing unexpired contracts may continue through their respective expiry dates under the ordinary process. Once the last listed contract expires, or the date specified in the notice arrives, the stock has no F&O contracts available for trading on that exchange.

Those statements apply only to the expiry months and dates named in the particular notice; they are not a universal calendar for every excluded security.

How to read the exchange circular
Do not rely on a headline saying that a stock has been “banned.” Open the notice issued by the relevant exchange and identify four items:
- The security: confirm the exact symbol and series, especially if the company has recently changed its name or undergone a corporate action.
- Remaining expiry months: note every futures and options month that the notice says will continue.
- Trading treatment: check whether existing contracts can trade normally, whether only position reduction is allowed, or whether the notice orders another restriction.
- Final date: record the date from which no contract will be available, rather than assuming that date is the last Thursday or another standard expiry day.
Contract specifications, settlement rules and the exchange notice control what happens to an individual position. A broker may remove the symbol from its order screen earlier for operational reasons, so compare the broker’s contract information with the exchange notice instead of treating a missing order button as proof that all contracts have expired.
What happens to positions that already exist?
Ordinary run-off to expiry
Under a routine exclusion, an unexpired futures or options contract in one of the listed remaining months can continue trading until that contract’s own expiry. The exchange is stopping the creation of new expiry months, not rewriting the expiry date printed in an existing contract. Liquidity, spreads and broker risk controls can still change as the run-off progresses.
New strikes in existing months
The exchange may add option strikes within an existing contract month even though it will not create a later month. This allows the listed series to reflect changing prices while the remaining expiries run off. It does not mean that a new expiry month has been opened.

Compulsory closeout is an exception
Do not interpret “available till expiry” as an unconditional guarantee. NSE’s selection criteria allow surveillance or corporate-action circumstances to result in compulsory closeout when continuing contracts are considered harmful to market integrity or market safety. A separate notice can therefore override the ordinary run-off treatment. Check for subsequent circulars affecting the same symbol.
Why can a stock leave the derivatives segment?
NSE’s current Selection Criteria – Equity Derivatives page says an existing F&O stock can exit after it has completed at least six months from introduction if it fails a relevant eligibility or Product Success Framework (PSF) criterion for three consecutive months. The assessment is based on performance in the underlying cash market and derivatives activity, not simply on one day’s price movement.
| Criterion published by NSE | Figure or test | What it measures |
|---|---|---|
| Market size and liquidity ranking | Top 500 stocks by average daily market capitalisation and traded value | Whether the underlying is among the largest and most actively traded shares |
| Order size | Median quarter-sigma order size of at least ₹75 lakh | The typical order value used in the exchange’s liquidity calculation |
| Market-wide position limit | At least ₹1,500 crore | The permitted aggregate open-interest capacity for the stock |
| Cash-market delivery | Average daily delivery value of at least ₹35 crore | Delivery-based participation in the underlying market |
| Product Success Framework | Participation, days traded, derivatives turnover and notional open interest tests | Whether the derivatives contract is being used sufficiently to remain viable |
These figures are from NSE’s current criteria page accessed October 13, 2026. Eligibility is tested across exchanges using underlying cash-market performance. The SEBI wording quoted by NSE says that if a stock meets the eligibility criteria on any exchange, it continues to be eligible for the derivatives segment on all exchanges. Conversely, failure across all exchanges can lead to exit.

NSE also describes a route involving repeated new-position bans. If a stock is subject to that restriction for a significant portion of the month for three months, it may be considered for phase-out after confirmation. That does not turn every temporary ban into an exclusion; it is one possible input to a later eligibility decision.

Exclusion versus a temporary F&O ban
Market participants often use “ban” for two different mechanisms. The distinction matters because the permitted trades, duration and prospects for normal trading are different.
| Comparison point | Temporary F&O ban | Exclusion from the F&O list |
|---|---|---|
| Trigger | Aggregate open interest exceeds the market-wide position limit (MWPL) threshold | Failure of eligibility or PSF tests, repeated ban-position conditions, or a surveillance/corporate-action decision |
| Trading allowed | From the next day, clients and trading members may trade only to decrease positions through offsetting trades | Existing listed expiries may trade under the notice; no fresh expiry month is issued in the ordinary phase-out |
| End point | Normal trading resumes when aggregate open interest falls to 80% of MWPL or below | Contracts run to the listed expiries or the final date in the exchange circular, subject to any compulsory-closeout action |
| Future availability | The stock can return to normal trading after the open-interest condition is cleared | NSE says the stock is not considered for re-inclusion for one year and must then satisfy the criteria for six consecutive months, with reintroduction subject to SEBI approval |
NSE Clearing’s Position Limits page, updated November 19, 2025 and accessed October 13, 2026, sets the temporary-ban thresholds at 95% for entering the restriction and 80% for resuming normal trading. The restriction limits increases in exposure; it does not by itself remove every listed expiry from the derivatives segment.
Historical examples of the timetable
The following NSE notices illustrate why the circular’s dates matter. They are historical examples, not a current exclusion list.
| NSE notice | Existing expiries allowed to continue | Date from which no contract was available |
|---|---|---|
| Circular NSE/FAOP/72950, February 23, 2026 | February, March and April 2026 expiry contracts for HUDCO, PPLPHARMA, TATATECH and TORNTPOWER, through their respective expiries; new strikes could be introduced in those months | April 29, 2026 |
| Circular NSE/FAOP/73769, April 16, 2026 | April, May and June 2026 expiry contracts for SAMMAANCAP, through their respective expiries | July 1, 2026 |
The examples show that two exclusions announced in the same year can have different remaining months and different final dates. A reader should never infer the timeline for one stock from another notice.

Can the stock return to F&O trading?
Re-entry is not immediate. NSE’s published criteria state that an excluded stock will not be considered for re-inclusion for one year. After that waiting period, it must meet the eligibility requirements for six consecutive months. Reintroduction is also subject to approval from the Securities and Exchange Board of India (SEBI). Meeting a single threshold for one month does not automatically restore the contracts.
The one-year period concerns consideration for re-inclusion; it does not create a right to a particular relisting date. Exchanges can update their criteria, and a later circular determines whether and when contracts are actually introduced.

- Find the latest exchange circular. Use the exchange’s circular archive and search the exact symbol. Check both NSE and BSE if the stock has derivatives on more than one exchange.
- Write down the remaining expiries and final date. Treat the dates in the notice as security-specific. Do not substitute the usual monthly expiry schedule.
- Check for follow-up notices. Surveillance action, a corporate event or a correction can change the treatment after the first exclusion announcement.
- Review the contract specification. Confirm settlement type, expiry, strike, lot size and the exchange’s rules for the particular series.
- Confirm your broker’s operational treatment. Ask how the broker will display, permit and settle the remaining series. Exchange-level availability does not establish how an individual broker’s interface will behave.
- Monitor liquidity and risk controls. A contract that remains technically listed can have wider spreads, fewer quotes or tighter broker margins as the listing runs off.
- Keep records of the notice. Save the circular and any broker communication so that the relevant expiry and final trading date are clear.
This checklist is for understanding the process, not a recommendation to hold, close or roll a derivative. The appropriate action depends on the position, contract terms and applicable risk controls.

Assuming exclusion means immediate cancellation
In the ordinary process, the first effect is the halt on new expiry-month issuance. Existing unexpired contracts can remain listed until their own expiries. Read the schedule before assuming that an open position has disappeared.

Treating a 95% MWPL ban as a delisting
A temporary ban is a reduce-only restriction triggered by aggregate open interest. It can end when open interest falls to 80% of MWPL or below. Exclusion is a separate phase-out with a published expiry schedule and a possible one-year re-entry wait.
Guaranteeing that every position will reach expiry
Surveillance or corporate-action action can require compulsory closeout. The ordinary run-off language is therefore conditional on there being no later instruction affecting the series.
Using an old notice as a current status report
Eligibility lists and exchange rules can change. Historical circulars demonstrate the mechanics but do not establish whether a stock is excluded today. Always verify the latest NSE, BSE and SEBI material before relying on a symbol’s status.
Bottom line for Indian market readers
Routine exclusion usually removes future expiry months first, lets the specifically named unexpired contracts run to their listed expiries, and ends with no F&O contract available after the date stated in the exchange circular. A temporary F&O ban is different: it restricts trades that increase exposure until open interest falls. For any particular stock, the authoritative answer is its latest exchange notice, followed by the contract details and any subsequent surveillance or corporate-action instruction.
