MCX May Face SEBI Penalty Risk After 4-Hour Trading Outage

The Multi Commodity Exchange (MCX) encountered a 4-hour trading disruption on October 29, 2025, following a sudden surge in activity that overwhelmed system limits, as per Reuters. The event has prompted regulatory attention and a likely penalty from SEBI due to the delay in system recovery and failure to identify the root cause swiftly.

MCX Trading Halt Triggers Regulatory Scrutiny

On October 29, 2025, MCX experienced a significant trading outage lasting over 4 hours. According to insider sources, the disruption stemmed from a capacity breach caused by an unexpectedly high volume of client activity. The exchange’s trading infrastructure hit a preset ceiling on the number of unique client codes, preventing normal operations from resuming quickly.

The Securities and Exchange Board of India (SEBI) is reportedly concerned over MCX’s delayed identification of the issue. Though the disaster recovery site was initiated as a backup, it also failed due to the same volume constraints, revealing systemic limitations in handling peak transactions.

System Constraints and Delay in Response

Post-incident, MCX clarified that the system was configured with predefined parameters that capped the number of active unique client codes. This limit was breached, leading to the halt. The exchange stated that it is now taking remedial steps to prevent similar occurrences and ensure better system scalability in the future.

As per the news reports, a quicker analysis could have enabled the exchange to restore trading more efficiently. The delay in recognising the core issue significantly contributed to prolonged trader uncertainty and market losses.

Traders Face Losses, Seek Representation

The extended outage had financial consequences, especially for bullion traders, many of whom held long positions in commodities like gold and silver as global prices started correcting. Traders reported being unable to exit positions in time, leading to substantial losses. The India Bullion and Jewellers Association Ltd (IBJA) is now planning to escalate the matter with SEBI on behalf of affected members.

Conclusion

MCX’s 4-hour outage due to a capacity overload has raised concerns over system resilience at India’s key commodity exchange. The potential regulatory penalty from SEBI underscores the importance of robust infrastructure, timely issue identification, and prompt recovery measures in maintaining market stability.
