NSE’s Surveillance department has issued Circular 348/2026 (Ref: NSE/SURV/74163) dated May 12, 2026, updating the Enhanced Surveillance Measure (ESM) framework. Eight securities are newly included in ESM Stage I, two securities are elevated from Stage I to Stage II, and no securities are being removed from the framework. All changes take effect May 13–14, 2026, with 100% margin requirements and mandatory migration from Rolling Settlement (EQ/SM) to Trade-for-Trade (BE/ST) segments.

Key Points

  • 8 securities newly added to ESM Stage I effective May 13, 2026: BHANDARI, CYBERMEDIA, FROG, MARALOVER, MAXVOLT, PATILAUTOM, VISASTEEL, ZIMLAB
  • 2 securities elevated from ESM Stage I to Stage II effective May 13, 2026: SANGINITA, VILINBIO
  • No securities are moving from Stage II to Stage I; no securities are being excluded from the ESM framework
  • All newly included and stage-shifted securities will shift from Rolling Settlement (Series: EQ/SM) to Trade-for-Trade segment (Series: BE/ST) effective May 14, 2026
  • Stage II securities will additionally be subject to a 2% price band under Periodic Call Auction effective May 13, 2026
  • ESM is applied purely for market surveillance purposes and does not constitute adverse regulatory action against the companies

Regulatory Changes

This circular references and builds upon prior ESM circulars: NSE/SURV/56948 (June 2, 2023), NSE/SURV/57609 (July 18, 2023), NSE/SURV/63361 (August 9, 2024), NSE/SURV/64066 (September 20, 2024), NSE/SURV/64400 (October 4, 2024), and NSE/SURV/69315 (July 25, 2025). Securities under ESM are subject to a minimum 100% margin on all open positions and new positions. The ESM framework operates in conjunction with all other prevailing surveillance measures imposed by the Exchanges.

Compliance Requirements

  • NSE Members/Brokers: Must apply a minimum 100% margin on all open positions as on May 13, 2026, and on all new positions created from May 14, 2026, for the listed ESM securities
  • Traders/Investors: Must be aware that affected securities are shifting to Trade-for-Trade segment — intraday trading will not be permitted; all trades must result in delivery
  • Stage II securities (SANGINITA, VILINBIO): Subject to 2% price band under Periodic Call Auction; participants must factor in severely restricted price movement

Important Dates

Date Event
May 12, 2026 Circular issued
May 13, 2026 ESM Stage I inclusions and Stage I→II elevations take effect; Stage II 2% price band under Periodic Call Auction begins
May 14, 2026 100% margin requirement applies to all open positions and new positions; EQ/SM to BE/ST segment migration effective

Impact Assessment

High impact for traders and investors holding or trading in the 10 affected securities. The mandatory shift to Trade-for-Trade eliminates intraday trading opportunities, requiring full delivery for all transactions. The 100% margin requirement significantly increases capital requirements for taking positions. Stage II securities (SANGINITA, VILINBIO) face the most severe restrictions with the additional 2% price band under Periodic Call Auction, substantially limiting daily price movement and liquidity. No securities are being removed from ESM in this update, indicating continued or increased surveillance pressure across the framework.
