Impact Assessment
This is a routine operational update affecting all members trading index derivatives in the F&O segment. Members who fail to update their contract files before April 1 may face trading disruptions or order rejections due to mismatched quantity freeze parameters. The limits apply to all five major index derivative products. Market impact is limited to operational compliance; the revised limits reflect updated computation based on the methodology prescribed in the consolidated circular.
Impact Justification
Routine periodic update to quantity freeze limits for index derivatives affecting all F&O members; requires mandatory contract file reload before April 1, 2026 trading session but does not introduce structural regulatory changes.
