As previously communicated, please be reminded of the upcoming changes to the F&O lot sizes for BANKNIFTY and MIDCPNIFTY, effective from 25 April 2025:
Revised Lot Sizes:
| Underlying Index | Symbol | Current Lot Size | Revised Lot Size |
|---|---|---|---|
| Nifty Bank | BANKNIFTY | 30 | 35 |
| Nifty Mid Select | MIDCPNIFTY | 120 | 140 |
Key points to note:
- No Fresh Positions: Starting 23 April 2025, no new positions in BANKNIFTY options with expiries on 25 Sept 2025, 24 Dec 2025, or 26 Mar 2026 will be permitted.
- Long (Option Buy) Positions: If you hold long positions in BANKNIFTY options with the above expiries, please square them off by 24 April 2025. Failure to do so may result in these positions becoming non-tradable post the lot size revision.
- Short (Option Sell) Positions: Ensure your existing short positions are in multiples of the revised lot sizes by 24 April 2025, 2:00 PM. Non-compliant positions may be subject to increased margin requirements and could be squared off partially or fully post the deadline.
Action required:
Square off or adjust your positions to align with the revised lot sizes before 24 April 2025 to avoid any disruptions.
