SEBI's New Index Derivative Lot Sizes
21st October '2024
12 PM IST
In line with SEBI’s latest regulation, the minimum contract value for index F&O will need to be at least ₹15 lakhs at the launch of new contracts. To comply with this, NSE will revise the lot sizes for all new index F&O contracts introduced from November 20, 2024, onwards.
 
Key Points to Note:
  • Current Contracts: Existing weekly and monthly index F&O contracts will retain their current lot sizes until they reach expiry.
  • New Contracts: Revised lot sizes will apply only to newly introduced contracts after the specified date.
