The Securities Appellate Tribunal is scheduled to hear the appeal filed by Jane Street Group against the interim order passed by market regulator Securities and Exchange Board of India on February 25. The appeal relates to SEBI’s July 3 interim order that imposed restrictions on Jane Street’s Indian operations over alleged market manipulation.

Strong financial performance before regulatory action

Jane Street’s Indian arm, JSI Investment Pvt., reported a sharp surge in profitability in the financial year ended March, before regulatory restrictions came into force. According to filings, the company’s net trading gains jumped to ₹47.0 billion, compared with ₹7.9 billion in the previous year, marking a growth of nearly 495%.

After-tax profit also rose sharply to ₹28.4 billion, up from ₹4.78 billion a year earlier, reflecting similar growth of around 495%. The net trading gains figure represents earnings after transaction costs, highlighting the scale of the firm’s trading activity in Indian markets during the period.

SEBI allegations and regulatory dispute

SEBI, in its interim order dated July 3, accused Jane Street of manipulating the Indian stock market and generating profits of over $4 billion through trading in stocks, futures, and options over a little more than two years ending March. The regulator imposed restrictions on the firm’s operations, citing concerns around market integrity.

Jane Street has denied the allegations and challenged SEBI’s findings. The company has sought access to information it considers essential for mounting its defence, arguing that the regulator’s conclusions are arbitrary and unsupported.

Subsidiary performance and capital position

A subsidiary of JSI Investment, also named in the SEBI order, reported contrasting results during the same period. The unit posted a net trading loss of ₹1.5 billion, even as it received a capital infusion of ₹8.6 billion from the parent entity. The subsidiary also disclosed outstanding borrowings of ₹32.0 billion, underscoring the scale of its balance sheet despite the loss.

Current operational status

As per government filings submitted in December, Jane Street’s Indian entities stated that they are not currently engaged in trading securities or derivatives. The companies indicated that they are evaluating whether and when to resume trading activities, depending on regulatory developments.

Wider industry context

The Jane Street case has drawn global attention and intensified scrutiny of proprietary and high-frequency trading firms operating in India. Other international firms such as Hudson River Trading and Optiver have also reported strong profit growth, even as regulators tightened oversight. SEBI is understood to be examining a wider range of trading strategies, including allegations of index-level manipulation linked to options trading.

The February 25 hearing before the Securities Appellate Tribunal is expected to be closely watched, as it could have implications not only for Jane Street’s future in India but also for regulatory oversight of sophisticated trading strategies in domestic markets.
