Top 500 Listed Companies Must Comply with New SEBI Trading Window Closure Rules by July 1, 2025

SEBI extends automated trading restrictions to immediate relatives of designated persons – Are you prepared?

The Securities and Exchange Board of India (SEBI) has issued a critical circular (SEBI/HO/ISD/ISD-PoD-2/P/CIR/2025/55) dated April 21, 2025, that significantly expands the scope of automated trading window closure compliance beyond designated persons to include their immediate relatives, on account of declaration of financial results. If your company is among India’s top 500 listed entities by market capitalization, immediate action is required.

What’s Changed: Key Updates to SEBI PIT Regulations

Extension to Immediate Relatives

Previously, automated trading window closure (freezing of PAN) applied only to Designated Persons (DPs). The new framework now extends these restrictions to immediate relatives of DPs, creating a broader compliance net that companies must manage.

Phased Implementation Timeline

SEBI has mandated a two-phase rollout:

Phase 1 (July 1, 2025) [Urgent]: Top 500 companies by BSE market cap as of March 31, 2025, listed on BSE, NSE, and MSEI

Phase 2 (October 1, 2025): All remaining listed companies and newly listed entities

Who Must Comply Immediately?

If your company ranks among the top 500 by BSE market capitalization as of March 31, 2025, and is listed on BSE, NSE, or MSEI, you have less than a month to ensure full compliance.

Who Are Immediate Relatives Under SEBI PIT Regulations?

According to SEBI Prohibition of Insider Trading Regulations 2015, immediate relatives include:
