The National Stock Exchange of India (NSE) has announced adjustments to the lot sizes of derivative contracts for key indices, which will take effect from 25 April 2025. This revision is in line with the Securities and Exchange Board of India (SEBI) guidelines for periodic modifications in derivatives trading.

Changes in Market Lot Sizes

The primary changes involve an increase in lot sizes for certain index derivatives. The lot size for Nifty Bank (BANKNIFTY) futures and options will increase from 30 to 35, while the lot size for Nifty Midcap Select (MIDCPNIFTY) will rise from 120 to 140. However, lot sizes for Nifty 50, Nifty Financial Services, and Nifty Next 50 derivatives will remain unchanged.

Existing monthly contracts set to expire in April, May, and June 2025 will continue with their current lot sizes. The revision will take effect for contracts expiring in July 2025 and beyond.

Implementation Timeline and Impact

For Nifty Bank, the new lot size will be applied to all contracts created after the close of trading on 24 April 2025. These updated contracts will be available for trading from 25 April 2025 onward. Additionally, all quarterly Nifty Bank contracts traded from this date will also reflect the revised lot sizes.

This adjustment is expected to streamline market operations and maintain efficiency in derivatives trading. Traders and investors dealing in these contracts should prepare accordingly for the upcoming changes.

Conclusion 

NSE’s revision of market lot sizes for key derivatives aligns with SEBI’s regulatory framework for derivatives trading. While the lot sizes for certain indices have increased, others remain unchanged. The implementation begins with July 2025 contracts, ensuring a smooth transition for traders and investors.
