Stock Market Holidays October 2026: The One That Moves Your Expiry

Two closed days, and the second one drags an expiry backwards#

October 2026 is a thin month for holidays and a strange one for traders. The exchanges shut on only two weekdays: Friday 2 October for Mahatma Gandhi Jayanti, and Tuesday 20 October for Dussehra. Both dates come from the NSE trading holiday circular of 12 December 2025, reference NSE/FAOP/71777, which BSE mirrors.

Two days off sounds trivial. It isn't, because of which days they are.

Tuesday is now the expiry day for every NSE derivative contract. Close the market on Tuesday 20 October and the weekly Nifty expiry does not vanish, it retreats to Monday 19 October. Anyone holding options through that week loses a session of time value they may have priced in. And 2 October falling on a Friday stretches the settlement of Thursday's trades into the following week.

If you trade, run a SIP, or just want to know which days your money is stuck, the calendar is worth ten minutes.

What a trading holiday actually is, and the three kinds you will meet#

A trading holiday is a day the stock exchange does not open. The exchanges publish the list a year ahead, but they do not invent it freely. Each holiday is tied to a state or national holiday, mostly Maharashtra's, because both NSE and BSE sit in Mumbai.

There are three separate calendars, and people confuse them constantly.

A trading holiday closes the market. No orders, no prices, no volume.

A clearing or settlement holiday keeps the market open but pauses the exchange of money and shares. You can buy on such a day, but the shares arrive later. NSE Clearing's capital market calendar for 2026 carries four dates that are not trading holidays at all: 19 February, 19 March, 1 April for annual bank closing, and 26 August. October has none of these, which keeps the month simple.

A bank holiday is declared by the Reserve Bank under the Negotiable Instruments Act and varies by state. Your bank branch may shut when the market is open, and vice versa.

One more thing about the published list: it can change. On 15 January 2026 both exchanges closed for municipal corporation elections in Maharashtra, announced about three days ahead and absent from the December circular. That addition took 2026 from fifteen weekday closures to sixteen, and it is a reminder that a holiday calendar is a forecast, not a contract.

If you want the authoritative version rather than a broker's summary, NSE publishes it under exchange communication with separate tabs for trading and clearing holidays and a dropdown for each segment: capital market, equity derivatives, currency derivatives, debt. BSE keeps its own list. The two match for equities, and the currency derivatives segment follows the same October dates.

October 2026, session by session#

Twenty trading sessions. That is what October leaves you, out of thirty-one calendar days. Across the year the count runs like this.

Calculated from the NSE holiday circular of 12 December 2025 plus the 15 January election closure. Bars start at zero. Excludes the Muhurat session on Sunday 8 November. Total for 2026: 245 sessions.

October sits in the middle of the pack, which is itself a change. Last year October carried Diwali and the Muhurat session, and Google search traffic for "stock market holiday" in India hit roughly 246,000 that month against a twelve-month average near 110,000, according to Google Ads volumes retrieved through DataForSEO. This year the festival load moves to November. Diwali Laxmi Pujan falls on Sunday 8 November 2026, with Muhurat trading to be held that day at timings the exchanges will notify separately. Diwali-Balipratipada on Tuesday 10 November is the full closure.

One small planning note. Neither October holiday builds a long break on its own. The 2nd is a Friday, which gives a three-day weekend, and the 20th sits in the middle of its week with normal trading on either side. Anyone hoping to stitch together four days off will have to spend leave to do it, and anyone assuming the market is shut for Dussehra week will lose four sessions of attention for no reason.

For comparison, the New York Stock Exchange closes on ten days in 2026 and none of them fall in October. American equity markets will be trading normally on both 2 and 20 October while Indian screens are dark.

The expiry that moves to Monday, 19 October#

In May 2025 SEBI issued circular SEBI/HO/MRD/MRD-TPD-1/P/CIR/2025/76, ordering that every equity derivative contract on a given exchange expire on either Tuesday or Thursday, and nothing else. NSE picked Tuesday. BSE picked Thursday. The change took effect from 1 September 2025, covering Nifty, Bank Nifty, Fin Nifty, Midcap Nifty and single-stock contracts.

When the designated expiry day is a holiday, the contract expires on the previous trading day. So:

Nifty weekly options that would have expired on Tuesday 20 October instead expire on Monday 19 October. The Nifty monthly contract expires on the last Tuesday, 27 October, which is a normal working day. On the BSE side, every Thursday in October 2026 is open, so Sensex weeklies run on 1, 8, 15, 22 and 29 October with the monthly on 29 October, untouched.

Why does a one-day shift matter? Options lose value as expiry approaches, a decay traders call theta. An option that expires on Monday has one fewer day of decay priced in than one expiring Tuesday, and the weekend sits inside that window. Sellers who assumed a Tuesday settlement collect less premium than they modelled. Buyers holding cheap out-of-the-money options lose a day of hope. Neither is catastrophic; both are avoidable by reading the contract's expiry date on your broker's screen rather than assuming.

Money in motion around the 2 October break#

Indian equities settle on a T+1 basis. Buy on Monday, and the shares reach your demat account on Tuesday; sell on Monday, and cash lands Tuesday. NSE Clearing states that in working out that date, "all intervening holidays, which include bank holidays, NSE holidays, Saturdays and Sundays are excluded".

Apply that to the first week of October. Trades done on Thursday 1 October would normally settle Friday 2 October. Friday is Gandhi Jayanti, so settlement rolls to Monday 5 October. If you sell shares on 1 October expecting the money for something on the 3rd, you will be waiting.

Your bank account is not affected the same way. RTGS has run round the clock on every day of the year since 14 December 2020, NEFT since December 2019, and UPI never stops. Money can move into your trading account on a holiday. It simply has nowhere to go until the market reopens.

Mutual funds follow their own clock. Units are allotted at the NAV of a business day, and AMFI's rules tie the applicable NAV to funds actually reaching the fund's bank account before the 3 p.m. cut-off. A SIP instalment dated 2 October will not get a 2 October NAV, because there isn't one. It gets the next business day's. For a monthly SIP this is noise. For a large lump sum in a volatile week, less so.

IPO timetables shift too. SEBI's T+3 listing rule, mandatory for issues opening on or after 1 December 2023, counts working days, so an issue closing near either holiday lists later on the calendar than the arithmetic suggests, and ASBA money stays blocked correspondingly longer.

Commodities keep half a day, and other open windows#

The equity exchanges are all-or-nothing. MCX is not.

Commodity trading runs in two sessions, roughly 9 a.m. to 5 p.m. and then 5 p.m. to about 11.30 p.m., the evening leg timed to overlap with London and New York. On some holidays only the morning session closes. That is exactly what happens on Dussehra: MCX shuts the morning session on 20 October and keeps the evening session open, a pattern confirmed in ICICI Direct's holiday listing. Gandhi Jayanti on 2 October is a full closure, both sessions.

So on the evening of 20 October, gold, silver and crude contracts trade while Nifty does not. If you hold a commodity position, a market holiday is not a day off.

International prices keep moving through both Indian holidays. Whatever gold does in London on 2 October, or the dollar does against the rupee, is waiting in the opening price when Indian screens come back. A closed exchange does not pause the risk in your portfolio, it only removes your ability to act on it, which is why leveraged positions carried into a long weekend deserve a second look.

None of that requires drama. Three habits cover most of it: read the expiry date printed on the contract instead of assuming Tuesday, count settlement in working days rather than calendar days when you need cash by a certain date, and check the MCX schedule separately if you hold commodities. That is roughly ten minutes of work for the month.

Key takeaways#

Indian equity markets close on two weekdays in October 2026: Friday 2 October (Mahatma Gandhi Jayanti) and Tuesday 20 October (Dussehra), leaving 20 trading sessions.
Because NSE contracts expire on Tuesdays and 20 October is shut, the Nifty weekly expiry moves back to Monday 19 October. The monthly expiry stays on Tuesday 27 October, and BSE's Thursday schedule is unaffected.
Trades executed on Thursday 1 October settle on Monday 5 October, since T+1 skips the holiday and the weekend.
MCX closes only its morning session on 20 October; the evening commodity session trades as usual. Gandhi Jayanti is a full commodity closure.
Diwali is a November event this year. Muhurat trading is scheduled for Sunday 8 November 2026, with the market closed on Tuesday 10 November for Balipratipada.

Frequently asked questions#

Is the stock market open on 2 October 2026? No. NSE, BSE and MCX are all closed for Mahatma Gandhi Jayanti, which falls on a Friday.

Is the market closed for the whole of Dussehra week? No. Only Tuesday 20 October is a holiday. Monday 19 and Wednesday 21 October are normal trading days.

What happens to my Nifty options expiring on 20 October? They expire on the previous trading day, Monday 19 October. Check the contract expiry shown by your broker before you take the position.

Can I place orders during a market holiday? Most brokers accept after-market orders, which queue for the next session's opening. They are not executed on the holiday itself.

Will my SIP be debited on a holiday? The bank mandate may be presented, but units are allotted at the NAV of the next business day once funds are realised before the cut-off.

Does Muhurat trading happen in October 2026? No. Diwali Laxmi Pujan is on Sunday 8 November 2026, and the Muhurat session is scheduled for that day at timings the exchanges will announce.

Are commodity markets closed on the same days as equities? Not always. MCX runs a split schedule on 20 October 2026, with the morning session closed and the evening session open.

Can the exchanges add a holiday after publishing the list? Yes. The 15 January 2026 closure for Maharashtra's municipal elections was announced separately, after the December 2025 circular.
