Global trading firm Jane Street is contesting SEBI’s manipulation allegations at the Securities Appellate Tribunal. Having deposited ₹4,843.57 crore into an escrow account, the firm is now demanding access to previous surveillance reports it claims clear its trading activity. The case highlights the ongoing regulatory scrutiny of algorithmic trading in India.
The global trading firm Jane Street is currently engaged in a high-stakes legal battle at the Securities Appellate Tribunal (SAT) regarding allegations of manipulation in the Bank Nifty index. The firm is seeking to overturn the Securities and Exchange Board of India’s (SEBI) interim order issued in July 2025, which accused the entity of using a specific trading strategy to distort index levels for illicit gains.
At the center of the firm's defense is an argument based on previous regulatory oversight. Jane Street contends that surveillance reports from the National Stock Exchange (NSE) and SEBI from November and December 2024—a period overlapping with the regulator's claims—did not identify any evidence of market manipulation. The firm is now attempting to use these earlier findings to challenge the regulator’s decision to open a fresh investigation, arguing that the two sets of regulatory findings are contradictory.
The proceedings have currently hit a procedural deadlock. Jane Street has formally requested the tribunal to compel SEBI to disclose additional internal documents and communications that were relied upon to build the case. The firm argues that this information is essential for a transparent defense. Conversely, SEBI has resisted these requests, maintaining that all necessary disclosures have already been provided to the parties involved.
For investors and market participants, the case underscores the significant regulatory uncertainty surrounding algorithmic and high-frequency trading strategies in India. Following the regulator's interim order, Jane Street complied with the directive to deposit ₹4,843.57 crore into an escrow account. This action allowed for the relaxation of certain market access restrictions initially imposed on the firm. However, Jane Street has since ceased its trading operations in the Indian market, citing the unpredictable nature of the regulatory environment.
The immediate monitorable for stakeholders is the upcoming tribunal decision regarding the scope of document discovery. If the tribunal orders SEBI to provide the requested internal files, it could significantly alter the direction of the case. Conversely, if the discovery request is denied, the firm will likely be forced to rely on its existing data to counter the regulator's allegations of improper trading. The outcome of this dispute is being closely watched, as it may set a precedent for how regulators handle and reconcile findings across different periods of market surveillance.
