NSE

In line with SEBI’s new rules for index derivatives, the minimum contract value for newly launched index F&O contracts should have a minimum contract value of Rs. 15 lakhs. Starting November 20, 2024, NSE will be revising the lot size for various indices to meet this criteria.

The lot size for existing contracts will remain the same until they expire, while the lot size for contracts being introduced after November 20, 2024, will be as follows:

Sr Underlying Index Symbol Existing Lot Size Revised Market Lot
1 Nifty 50 NIFTY 25 75

3 Nifty Financial Services FINNIFTY 25 65
4 Nifty Midcap Select MIDCPNIFTY 50 120
5 Nifty Next 50 NIFTYNXT50 10 25

The lot size for quarterly and half-yearly contracts will be revised from December 26, 2024, end of the day for Nifty, and December 24, 2024, end of the day for Nifty Bank. Other indices, Nifty Next 50, Nifty Financial Services, and Nifty Midcap Selcect do not have quarterly and half-yearly contracts.

Note: After December 26, 2024, for Nifty, and December 24, 2024, for Bank Nifty, if you hold F&O contracts in quarterly or half-yearly expiries that do not match the new lot size, you won’t be able to close the position and will have to hold it until expiry.

To avoid this, you can either buy or sell more contracts to match the revised lot size or square off the position beforehand.

Till 26th December 2024, nothing will change for you. After 26th December 2024, the lot size for these contracts will change to 75. So, if you don’t exit your contracts before 27th December 2024, you won’t be able to exit your positions after that. You will have to hold your contracts till they expire in December 2025.

As long as you have positions with multiples of the new lot size it won’t be a problem. If no, then you can add more lots to make the position a multiple of the revised lot size. Or if you don’t have more capital you may exit the trade before the revised lot size comes into effect.

SEBI’s new rules require the minimum contract value for index F&O to be at least ₹15 lakhs. Do these changes affect the lot sizes and margins for index stocks in F&O?

10

No … thse changes only fr index

So there will be two Weekly Expirations, and on the Last Week of every month, it will be every day as all Monthly Contracts Expire. Is that right?
