What this circular covers

SEBI issued this Master Circular on Surveillance of Securities Market on 15 May 2026, consolidating earlier surveillance-related circulars into one reference framework and rescinding the individual circulars it supersedes. It applies to stock exchanges, depositories, listed companies, and intermediaries/fiduciaries covered under the SEBI (Prohibition of Insider Trading) Regulations, 2015, and is organised subject-wise under five heads: trading-in-dematerialised-form requirements; monitoring of unauthenticated market rumours/news circulated by intermediaries on social media, messaging apps and email; a newly incorporated Financial Disincentives for Surveillance-Related Lapses framework applicable to Market Infrastructure Institutions (MIIs); disclosure/reporting duties under the PIT Regulations; and trading-window-closure mechanics.

Notable updates folded into this consolidation include financial disincentives for MIIs that have surveillance lapses, restrictions on subscribing to non-convertible securities during a trading-window closure period, and extending automated trading-window-closure alerts to the immediate relatives of designated persons around financial-results announcements. The 8 paragraph-map entries below break this consolidated circular into operational checkpoints — from applicability and registration conditions (MC-01, MC-02) through governance, onboarding, operational conduct and disclosure (MC-03–MC-06), to inspection/audit readiness and the supersession/concordance table showing which earlier circulars this one replaces (MC-07, MC-08).
