India's market regulator has lifted a trading ban on Copthall Mauritius Investment, a JPMorgan Chase unit, after the firm deposited 29.6 million rupees ($\text{INR } 2.96 \text{ crore}$) in alleged unlawful gains.
New Delhi — Indian capital markets authorities lifted the trading restrictions imposed on Copthall Mauritius Investment Ltd., a Mauritius-based unit of JPMorgan Chase & Co., alongside domestic broker Mansi Share and Stock Broking. Disclosed on September 9, 2026, the regulatory development follows compliance actions taken by the firms, which deposited a combined total of approximately 36.8 million rupees in alleged wrongful gains. The initial interim order, issued on August 19 by the Securities and Exchange Board of India ($\text{SEBI}$), had barred both entities from accessing local capital markets following allegations of market manipulation during the Bombay Stock Exchange ($\text{BSE}$) closing auction on August 13.
Investigation Into Closing Auction Session Manipulation
According to official regulatory filings and enforcement summaries, the investigation centers on trading anomalies observed during the newly introduced Closing Auction Session ($\text{CAS}$)—a mechanism implemented on August 3, 2026, to align domestic price-discovery frameworks with international standards. $\text{SEBI}$ alleged that Copthall placed outsized buy orders in Sensex constituent stocks near allowable price bands, while Mansi Share placed large sell orders, subsequently canceling significant portions. The regulator stated that these synchronized order patterns artificially influenced indicative equilibrium prices, benefiting derivatives positions during the weekly Sensex options expiry.
While the deposit of the disputed sums—29.6 million rupees for Copthall and 7.16 million rupees for Mansi—allowed for the immediate lifting of the trading prohibition, statutory inquiries remain active. Market analysts note that the volatile rollout of the $\text{CAS}$ framework has prompted $\text{SEBI}$ to evaluate potential structural refinements for derivative settlement calculations.
Impact on Institutional Investors, Market Compliance, and Trading Participants
For international institutional investors and foreign portfolio managers operating in Indian markets, strict regulatory enforcement underscores the zero-tolerance stance toward cross-market manipulation between cash auctions and derivative segments. For the broader financial ecosystem, clearing the trading suspension restores operational status to key institutional conduits while judicial and regulatory proceedings proceed toward a confirmatory order.
