In one of its most aggressive moves yet, the Securities and Exchange Board of India (Sebi) has taken strong action against US-based high-frequency trading firm Jane Street, uncovering a strategy it called “manipulative” and designed to dodge regulatory oversight. The interim order issued on July 3 has not only rocked Jane Street but also triggered a wave of concern among global HFT firms operating in India through similar structures.<\/p>\n

The Heart of the Controversy: Dual Entities and Regulatory Bypass<\/strong><\/h2>\n

At the center of Sebi\u2019s action is Jane Street\u2019s Indian arm \u2014 JSI Investments Pvt Ltd \u2014 which the regulator alleges was used to bypass restrictions placed on foreign portfolio investors (FPIs), especially around intraday and derivatives trading. Sebi\u2019s order states:<\/p>\n

\n

\u201cIt appears that the incorporation of JSI Investments enabled Jane Street to work around the prohibition in FPI Regulations, and execute the manipulative scheme without explicitly violating them.\u201d<\/em><\/p>\n<\/blockquote>\n

What\u2019s more concerning for the industry is that this model isn\u2019t unique to Jane Street. Top global firms like Citadel Securities, IMC Financial Markets, and Jump Trading are known to operate in India through similar dual-entity structures\u2014a domestic trading desk under Indian registration and an FPI arm in tax-efficient jurisdictions like Singapore or Hong Kong.<\/p>\n

A Common Practice Now Under Spotlight<\/strong><\/h2>\n

These dual setups are designed to leverage the tax arbitrage: while Indian entities pay taxes on derivative profits (10\u201315%), FPIs from treaty countries like Singapore are exempted. This arrangement, combined with regulatory asymmetries, made India\u2019s booming derivatives market an attractive ground for sophisticated global players.<\/p>\n

However, Sebi\u2019s observation\u2014that Jane Street\u2019s Indian and foreign arms were placing opposing trades in the same securities while being under common control\u2014has sparked compliance concerns across the trading world.<\/p>\n

While such \u201ccontra orders\u201d by separate entities aren\u2019t technically illegal, Sebi emphasized that coordinated execution through algorithms under a single ownership can amount to market manipulation.<\/p>\n

\n

\u201cWhen you have a group structure and shared ownership, even separate legal identities can end up moving markets if they act in sync\u2014intentionally or algorithmically,\u201d<\/em> explained a person familiar with HFT strategies.<\/p>\n<\/blockquote>\n

HFT Firms on Alert: Algorithms Under Review<\/strong><\/h2>\n

The algorithmic execution of these trades adds to the complexity. More than 99% of trades by these firms are algorithm-driven, often running without real-time human intervention.<\/p>\n

\n

\u201cEach algo follows its own code. It\u2019s possible that two entities within the same group take opposite positions, not to game the market, but due to how each model reacts to signals,\u201d<\/em> said an insider with direct knowledge.<\/p>\n<\/blockquote>\n

Despite this, Sebi\u2019s broader interpretation of intent and impact has put algo strategies under scrutiny, particularly in illiquid counters where intra-group trading could lead to distortions.<\/p>\n

Impact on the Industry: Time to Reassess Structures<\/strong><\/h2>\n

Insiders say the fallout from the Jane Street case could be far-reaching. Many brokers and funds may now have to reconfigure their algo systems, and in some cases, rethink their entity structures to avoid regulatory heat.<\/p>\n

\n

\u201cSome brokers will now have to rework their algorithms to ensure there\u2019s no overlap or contradiction within the group,\u201d<\/em> said a market participant.<\/p>\n<\/blockquote>\n

Though Sebi has not officially named other firms, emails to Citadel, Jump, and IMC remained unanswered. It is also not clear which exact entities may be under the lens.<\/p>\n

The Bigger Message: Sebi\u2019s No-Nonsense Approach<\/strong><\/h2>\n

With this case, Sebi has made it clear\u2014even the most sophisticated global trading firms are not above scrutiny. The regulator has ordered the impounding of \u20b94,843 crore in alleged illegal gains, describing the trading pattern as \u201cmanipulative\u201d and \u201cstructured to avoid regulatory oversight.\u201d<\/p>\n

Legal experts believe the matter may now head to Indian courts, which will likely need to define whether it\u2019s the structure or the intent behind such trading that breaches securities law.<\/p>\n
