F&O batch size update: The National Stock Exchange of India (NSE), the country’s largest bourse, has increased the lot size of F&O in line with new SEBI regulations. The lot size for Nifty 50 has increased from 25 to 75, while the lot size for Bank Nifty has increased from 15 to 30. These new lot sizes will remain in effect for the current contract until the next expiration.

This week, SEBI also increased the position limit for index futures and options (F&O index contracts) to Rs 7,500 crore or 15 per cent of open interest. This increased limit applies to both brokers and clients, and due to a decrease in open interest, there will be no penalty for positions exceeding the limit.

Additionally, SEBI has extended the deadline for funds to be transferred directly from clearing to customer accounts. The implementation date of the new rules for settlement and payment of shares has been postponed from October 14 to November 11, 2024.

As per the new SEBI guidelines, the arrival time of actions on customer accounts under the T+1 settlement model will also change. Instead of being credited before 1:30 p.m. the day after settlement, shares will now be available in accounts before 3:30 p.m. the same day. The adjustment is part of SEBI’s efforts to provide more time to market participants, including exchanges, depositories and brokers, to fully integrate their technical infrastructure with the new system.
