In a significant regulatory move, the National Stock Exchange (NSE) has announced an increase in the lot sizes for all five of its index derivative contracts, effective November 20, 2024.
This decision comes in response to an order from the Securities and Exchange Board of India (SEBI), aimed at enhancing investor protection in the derivatives market.
The NSE's circular reveals that the Nifty50 lot size will increase threefold, from 25 contracts to 75.
Additionally, the Nifty Bank lot size will double from 15 to 30 contracts. Other notable changes include the Nifty Financial Services (Fin Nifty) lot size, which will rise from 25 to 65, and the Nifty Midcap Select lot size will jump from 50 to 120.
The Nifty Next50 will see its lot size increase from 10 to 25 contracts.
The circular also specifies that existing weekly and monthly expiry contracts will retain their current lot sizes until their respective expiry dates.
However, quarterly and half-yearly contracts will transition to the new lot sizes on December 24, 2024, for Bank Nifty, and December 26, 2024, for Nifty.
This adjustment follows SEBI's announcement earlier this month of a six-step framework designed to address concerns about household losses in the high-risk environment of futures and options trading.
Under the new regulations, the minimum contract size for index futures and options will rise from the current range of Rs 5-10 lakh to Rs 15 lakh at the time of introduction.
Furthermore, the lot size will be set to ensure that the contract value remains within Rs 15 lakh to Rs 20 lakh on the day of review.
SEBI emphasized that this recalibration in minimum contract size aligns with market growth and is intended to maintain an appropriate suitability and appropriateness criterion for participants, given the inherent leverage and risks associated with derivatives trading.
