SEBI Master Circular on Securities Market Surveillance 2026: Key Compliance Changes for Listed Companies, Intermediaries and MIIs

The Securities and Exchange Board of India (“SEBI”) has issued an updated Master Circular consolidating various circulars and regulatory instructions relating to securities market surveillance. The circular brings together provisions governing insider trading compliance, trading window restrictions, disclosure requirements, system-driven disclosures, and the surveillance obligations of Market Infrastructure Institutions (“MIIs”), while superseding earlier surveillance-related circulars.

The Master Circular incorporates several recent regulatory developments, including the framework for financial disincentives for surveillance-related lapses by MIIs, the clarification permitting subscription to Non-Convertible Securities during trading window closure periods subject to applicable conditions, and the extension of automated trading window closure restrictions to immediate relatives of Designated Persons under the SEBI (Prohibition of Insider Trading) Regulations, 2015.

The circular also strengthens compliance requirements by mandating robust surveillance and monitoring systems for stock exchanges, depositories, intermediaries, listed entities, and fiduciaries. Further, it consolidates the PAN-ISIN freeze mechanism, system-driven disclosures, and standardized disclosure formats to strengthen insider trading controls and market integrity.

Conclusion

The Master Circular serves as a comprehensive consolidation of SEBI’s surveillance framework and reinforces regulatory expectations relating to market monitoring, insider trading compliance, and governance standards across the securities market ecosystem.
