F & o trading: The National Stock Exchange (NSE) has announced a change in lots of futures and options (F&O) contracts. These new changes will be applicable from 28 October 2025. Under this, the lot sizes of Nifty 50 and three other major index have been reduced.
According to the NSE circular, the lot size of the Nifty 50 has now been reduced from 75 to 65. At the same time, the lot size of the Nifty Bank has come down from 35 to 30. Apart from this, the lot size of Nifty Financial Services has been reduced from 65 to 60 and the lot size of the Nifty Mid Select Index has been reduced from 140 to 120. However, the lot size of derivative contracts of the Nifty Next 50 index will remain the same as before.
Investors can trade up to the expiry of 30 December 2025 with the current lot size. After this, all new contracts of any period will be available in the modified lot size.
The statement issued by the NSE said, “Members are advised to inform their clients, who have a position or who want to take a new position, that the dates mentioned below will apply changes in lot size.”
The last expiry with the existing lot size for the Nifty’s Weekly and Monthly Contracts will be on 23 December 2025, while the last expiry of the monthly Nifty and the bank Nifty contract will be held on 30 December 2025.
Let us know that from time to time the National Stock Exchange (NSE) keeps changing the lots of futures and options (F&O) contracts so that the contract value remains within a standard realm. This makes contracts more economical for traders and investors.
Since derivatives are leveraged instruments, traders do not have to pay the entire value of the contract in advance, but the lot size determines their exposure and margin requirement. NSE believes that such modifications help maintain market efficiency and liquidity.
