NSE Announces Revised Quantity Freeze Limits for Index F&O Contracts Effective September 1

MUMBAI: The National Stock Exchange (NSE) has announced a revision to the quantity freeze limits for index futures and options (F&O) contracts. The updated limits are scheduled to become effective starting September 1, 2026.

According to the exchange's circular, the revised limits establish specific maximum quantities that can be placed in a single order across various indices. Under the new guidelines, the quantity freeze limit for Bank Nifty is set at 600, while Nifty and FinNifty have each been assigned a limit of 1,800. Additionally, Midcap Nifty has a limit of 2,800, Nifty Next 50 is capped at 600, and NiftyFPI has a limit of 8,500.

The exchange clarified that the quantity freeze limit represents the maximum quantity permitted in a single order. Any orders that exceed the specified limit will need to be split by market participants. Furthermore, NSE emphasized that these revised limits function purely as order-size restrictions and do not represent position limits or open interest (OI) limits.

The exchange stated that these revised limits have been prescribed pursuant to its quantity-freeze provisions for futures and options contracts under the F&O consolidated circular dated April 28, 2026.

In preparation for the upcoming changes, the exchange has advised all trading members to load the updated contract files into their respective trading applications before trading commences on the effective date.

"The revision of quantity freeze limits by the National Stock Exchange is an important operational update for market participants and trading members. By setting clear single-order caps across different index contracts, such as Bank Nifty, Nifty, and FinNifty, the exchange ensures better order management and risk control. Trading firms and active market participants must ensure their systems and trading applications are updated with the new contract files ahead of the September 1 effective date to maintain seamless execution and compliance." — Dr. Shishir Gupta, Founder & CEO, StartupLanes
