Mumbai: The National Stock Exchange (NSE) has announced changes to market lot sizes for four major index futures and options contracts, including the Nifty 50, effective from October 28.
Under the revision, the Nifty 50 lot size will be reduced from 75 to 65, while the Nifty Bank lot size will fall from 35 to 30. The Nifty Financial Services lot size will drop from 65 to 60, and the Nifty Mid Select index will decrease from 140 to 120. The Nifty Next 50 Index lot size will remain unchanged.
Investors can continue trading with the current lot sizes until the expiry of contracts on December 30, 2025, after which all new contracts will follow the revised sizes. Weekly and monthly Nifty contracts will expire on December 23, and monthly Nifty and Bank Nifty contracts will expire on December 30, after which the new lot sizes will apply.
The NSE said the revisions aim to standardise contract values, keep them affordable, and enhance market efficiency and liquidity. While derivatives allow leveraged trading without paying the full contract value upfront, lot sizes determine exposure and margin requirements.
“Members are advised to inform clients holding positions or planning new positions in quarterly and half-yearly contracts about the upcoming revision,” the NSE said.
