India’s market regulator has intensified its investigation into an alleged front-running network involving veteran market operator Ketan Parekh, with fresh show cause notices issued to six foreign portfolio investors (FPIs) managed by US-based asset management giant Capital Group. The action marks the first time the global investment firm has been directly identified in regulatory proceedings tied to the case, after earlier references only described it as a large institutional client.

According to reports, the Securities and Exchange Board of India (Sebi) has initiated proceedings against six Capital Group-linked FPIs — Smallcap World Fund, American Funds Insurance Series Growth-Income Fund, American Funds Fundamental Investors, The Growth Fund of America, AMCAP Fund and Capital Group AMCAP Fund (Lux). The regulator’s probe reportedly spans from January 2021 to June 2023.

The investigation centres around alleged breaches in maintaining confidentiality of large institutional trading orders. Sebi reportedly found that sensitive non-public trade information linked to Capital Group entities was shared ahead of execution, enabling certain market participants to take positions before the institutional trades were placed in the market.

The regulator has alleged that two Capital Group traders — James Vincent Cheng and Terence Tsai — communicated details of impending trades to Singapore-based trader Rohit Salgaocar, who is associated with Strait Crossing Pte Ltd, an entity reportedly not registered in India. Sebi further alleged that Salgaocar passed this information to Ketan Parekh and associated entities, allowing them to build positions in specific stocks before the large FPI orders were executed.

The alleged information flow reportedly included stock names, trade quantities, execution prices and transaction timing. Such practices fall under the definition of front-running, where traders illegally benefit from advance knowledge of large market-moving orders.

The case is drawing attention because it involves one of the world’s largest investment management firms. Capital Group oversees more than $3.3 trillion in assets globally and is regarded as a long-term institutional investor with significant exposure across emerging markets, including India.

Sebi’s findings were reportedly based on an examination of Bloomberg chat records and WhatsApp communications. The regulator believes these communication trails indicate systematic sharing of sensitive trading information between involved parties over an extended period.

The development comes at a time when Indian regulators are strengthening oversight around algorithmic trading, market surveillance and institutional conduct. India’s equity markets have witnessed a sharp rise in participation from domestic retail investors and foreign institutions over the past five years, increasing the importance of maintaining confidence in market integrity and fair trading practices.

For the broader market ecosystem, the case reinforces Sebi’s increasingly aggressive stance on insider trading and market manipulation. The regulator has expanded its surveillance capabilities significantly in recent years, using data analytics and digital communication records to investigate suspicious trading patterns.

From a market structure perspective, the investigation could lead to tighter compliance expectations for global asset managers operating in India. Institutional investors may face greater scrutiny over internal controls, employee communications, trade execution systems and information-sharing protocols between offshore desks and intermediaries.

The episode may also increase operational caution among foreign portfolio investors executing large block trades in Indian equities. Dealers and brokers handling institutional flows could witness stricter monitoring standards if Sebi decides to tighten operational compliance norms following the investigation.

For Indian markets, the immediate systemic risk appears limited because the matter relates to alleged misconduct tied to trading practices rather than broader financial instability. However, reputational implications for institutional trading standards could remain under focus if the investigation uncovers deeper coordination networks or wider market participation.
