The revision in lot sizes for index derivatives is designed to keep the contract values within SEBI’s range. Ensure you’re aware of the expiry dates for both monthly and quarterly contracts. If you hold positions, make sure to adjust them before December 30, 2025, to avoid complications.
what about long-dated contract i.e Expiring on Dec 2026 ?
I am holding “NIFTY 26DEC 25000 PE” of 75 quantity then should i exit from my position ?
if so after which date we can buy long dated contracts with modified quantity
@rajesh_kumar_sahoo you can square off 65 units after December 30, 2025. However, the remaining 10 qty will be cash settled upon expiry.
Really sebi making a headache for us , they are gambling with trader ,
sebi only increase the lot size , now they are decreasing , all calculation are went wrong in index

index derivative contract is valued between ₹15 lakh and ₹20 lakh
For a nifty DEC 2026 contract, does the same rule apply?
lets say for a particular strike, i currently have 1 lot of 75, it’s lot size will also change?
Your Lot size won’t change. But tradeable lot size will and you will no longer be able to sell/buy 75 as 1 lot, but only 65. So you won’t be able to close 10/lot until expiry unless you close tomorrow.

Revision for quarterly and half-yearly contracts
| Index Derivatives | Expiration Cycle | Expiry Date | Particulars |
|---|---|---|---|
| NIFTY | Quarterly & Half-yearly | 31-Mar-2026* | Revised from Dec 30, 2025 (EOD) |
appears as though this is last expiry.
Nifty is the only one with ultra long dated expiries.
