SAT Reserves Order in Jane Street-Sebi Evidence Dispute
Jane Street and India’s securities regulator, Sebi, disagree about records connected to a market-manipulation case.
Sebi says Jane Street’s trading affected the Bank Nifty index and helped its options positions.
In July 2025, Sebi barred the firm from India’s securities market and ordered it to give back ₹4,843 crore in alleged unlawful gains.
Jane Street says it needs more documents to defend itself.
It has asked for detailed trade and order records, including information about the other parties in the trades.
It also wants correspondence between Sebi and the National Stock Exchange.
Sebi says some of the requested information, especially counterparty details, is not relevant to its allegations.
The Securities Appellate Tribunal has finished hearing arguments and will issue its order on 21 October.
The tribunal’s decision will address Jane Street’s appeal over access to evidence.
The Securities Appellate Tribunal reserved its order until 21 October on Jane Street’s appeal.
The appeal concerns Jane Street’s access to evidence in its dispute with India’s securities regulator, Sebi.
Sebi’s July 2025 interim order barred Jane Street from the Indian securities market and directed it to disgorge ₹4,843 crore in alleged unlawful gains.
Sebi alleges Jane Street manipulated the Bank Nifty index through cash- and futures-market trades while building large short positions in index options.
Jane Street says key trade records and regulator correspondence are needed for its defence; Sebi says counterparty data is irrelevant and need not be disclosed at this stage.
