Tribunal to Deliver Verdict on Jane Street Plea Against Market Watchdog on October 21

The Securities Appellate Tribunal has reserved its order until 21 October on an appeal filed by Jane Street. The US-based market maker is challenging a July 2025 interim order by the Securities and Exchange Board of India that barred the firm from the Indian securities market and ordered it to hand over ₹4,843 crore in alleged illegal gains. The regulatory body accused the hedge fund of manipulating the Bank Nifty index. According to the charges, the firm used cash and futures trades to prop up the index while taking large short positions in index options. During hearings before a tribunal bench including Justice P. S. Dinesh Kumar, Dr. Dheeraj Bhatnagar, and Meera Swarup, Jane Street argued that the market regulator withheld key documents. The firm wants access to trade and order logs with counterparty details like quantity, price, and execution time, plus messages between the regulator and the National Stock Exchange. The hedge fund stated these papers are vital to defend itself and to understand why a fresh probe started after two earlier reviews cleared it. Those reviews include a November 2024 National Stock Exchange probe and a December 2024 review by the regulator's Integrated Surveillance Department, both of which reportedly found no proof that the trades hurt index prices. Regulator lawyers countered that counterparty data has no bearing on the charges and that the agency is only required to share information it actually used for the interim order. A lawyer for the agency noted that the trades involved are massive and counterparty details are not relevant to the current allegations.

Context

Tribunals like this one act as independent bodies to hear appeals against decisions made by financial regulators. Market watchdogs use interim orders in urgent situations to protect investors while investigations continue. Legal disputes over access to documents often center on how much investigative data must be shared with defendants during ongoing proceedings.
