Jane Street vs SEBI: SAT Hearing Today on Market Manipulation Charges; Key Test for High-Speed Traders

A three-member bench of the Securities Appellate Tribunal (SAT), under Justice P.S. Dinesh Kumar, will convene on Tuesday to hear a critical appeal by New York-based trading firm Jane Street Group LLC against the Securities and Exchange Board of India (SEBI). At stake is the regulatory handling of alleged market manipulation in India's equity derivatives segment, the largest of its kind in the world.

Jane Street Faces Off India Market Regulator SEBI

Jane Street filed its appeal challenging a July interim order by SEBI that accused the firm of engaging in manipulative trading practices. The firm claims SEBI denied access to vital documents necessary for mounting a defense. As part of its appeal, Jane Street has urged the tribunal to halt any further regulatory actions until the appeal is resolved.

Document Access Dispute

According to court papers, Jane Street is requesting access to internal communications - specifically emails involving SEBI and Mayank Bansal, a Dubai-based hedge fund manager reported to have reported Jane Street's trading to the regulator. The firm is also seeking emails between SEBI and the National Stock Exchange of India (NSE), which it alleges were dismissed by SEBI as irrelevant.

On Tuesday, Jane Street plans to request a pause in the investigation if more time is needed to determine whether SEBI is obstructing its defense by withholding documents. Typically, initial hearings set the stage for future proceedings, with the court summoning SEBI to address allegations later.

Past Findings and Legal Implications

Jane Street's appeal highlights that both the SEBI surveillance department in December and the NSE, a month earlier, reviewed the firm's transactions and found no evidence of market manipulation. With this, the firm argues there is no basis for SEBI's interim order.

The case carries substantial implications not only for Jane Street but also for other leading global quantitative trading entities, including Jump Trading, Citadel Securities, and IMC Trading, which all operate within India's highly liquid derivatives market.

Jane Street VS SEBI: What to Expect in the Hearing

On Tuesday, Jane Street will likely seek an interim stay on the investigation to allow adequate time for examining whether SEBI has improperly denied access to defence-critical documents. Legal experts suggest that initial hearings typically set the stage for future proceedings, including summoning SEBI to address the allegations and present its side of the case.

Implications for High-Speed Trading

India's derivatives market has become attractive for global high-speed trading firms after volumes surged post-pandemic due to new individual traders entering the market. However, retail traders lost approximately $12 billion in futures and options in fiscal 2025, according to a SEBI report earlier this year, primarily benefiting sophisticated trading firms.
