NSE increases lot sizes for F&O: Key updates on SEBI regulation

F&O Lot Size Update: The National Stock Exchange of India (NSE), the country's largest stock exchange, has increased the lot sizes for F&O in accordance with new SEBI regulations. The lot size for Nifty 50 has risen 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 expiry.

This week, SEBI also raised the position limit for Index Futures and Options (Index F&O 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 penalties for positions exceeding the limit.

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

Under the new SEBI guidelines, the arrival time for shares in client accounts under the T+1 settlement model will also change. Instead of being credited by 1:30 PM on the next day after settlement, shares will now be available in accounts by 3:30 PM on the same day. This adjustment is part of SEBI's effort to provide more time for market participants—including stock exchanges, depositories, and brokers—to fully integrate their technical infrastructure with the new system.
