NSE has notified the inclusion of 10 securities under the Long-Term Additional Surveillance Measure (Long Term-ASM) Stage-I framework effective April 21, 2026, along with movement of 1 security from Stage-I to Stage-II. A 100% margin requirement will apply on all open and new positions from April 23, 2026. Securities qualifying under criteria VII (Stage-IV) will be transferred from the Rolling Settlement segment (Series: EQ) to the Trade-for-Trade segment (Series: BE).

Key Points

• 10 securities newly shortlisted under Long-Term ASM Stage-I w.e.f. April 21, 2026
• 2 securities (BHAGYANGR, SVPGLOB) moved from Short-Term ASM (STASM) to Long-Term ASM (LTASM) framework
• 1 security (PEARLPOLY) satisfies criteria at BSE
• 1 security (INSPIRE) moves from Long-Term ASM Stage-I to Stage-II w.e.f. April 21, 2026
• No securities shortlisted under Stage-IV or Stage-II to Stage-III movement
• 100% margin applicable on all open positions as on April 22, 2026 and new positions from April 23, 2026
• ASM framework operates in conjunction with all other prevailing surveillance measures

Regulatory Changes

Circular Ref No: NSE/SURV/73812 (Download Ref) / 282/2026 (Circular Ref), issued under the Long-Term ASM framework established by prior circulars: NSE/SURV/39265, NSE/SURV/45111, NSE/SURV/46557, NSE/SURV/48506, NSE/SURV/52090, NSE/SURV/63362, and NSE/SURV/64066. Securities meeting criteria VII (Stage-IV) will be shifted from Rolling Settlement (EQ series) to Trade-for-Trade settlement (BE series).

Compliance Requirements

• Members must maintain 100% margin on open positions held as of April 22, 2026, and on all new positions in ASM-listed securities from April 23, 2026 onwards
• Members should update their systems to reflect segment change (EQ to BE) for any Stage-IV securities
• Members must inform clients of applicable margin and settlement changes for affected securities

Important Dates

• April 21, 2026: ASM inclusion effective for newly shortlisted securities; Stage-I to Stage-II movement effective
• April 22, 2026: Reference date for open positions subject to 100% margin
• April 23, 2026: 100% margin requirement comes into effect; Trade-for-Trade segment shift effective for Stage-IV securities

Impact Assessment

The 100% margin requirement significantly increases the cost of holding or creating positions in the 10 newly listed securities, likely reducing liquidity and increasing volatility. The Stage-I to Stage-II progression for INSPIRE Films Limited indicates continued regulatory scrutiny. BHAGYANGR and SVPGLOB, migrated from STASM to LTASM, face a stricter and longer-duration surveillance regime. No securities were placed under Stage-IV at this time, so no segment migration (EQ to BE) is triggered in this circular. Traders and investors in affected securities should reassess positions given the heightened margin and monitoring requirements.
