Sebi Calls Jane Street’s Document Demand a Delaying Tactic
India’s market regulator, Sebi, and trading firm Jane Street are arguing about a market-manipulation case.
Sebi says Jane Street’s trades affected prices in a bank index and helped its options trades.
Jane Street denies that its case can be fairly tested without seeing the trading records Sebi used.
The firm has asked a tribunal to make Sebi share more records and emails.
Sebi says it only has to share the documents it relied on and that more disclosure could hurt its investigation.
Sebi’s lawyer accused Jane Street of using its document request to delay the case.
An interim order has stopped the firm from trading in Indian securities, and it placed 48.4 billion rupees in an escrow account.
The hearing is set to continue Wednesday.
At a Securities Appellate Tribunal hearing, Sebi lawyer Gaurav Joshi called Jane Street’s request for more documents a “dilatory” tactic.
Jane Street says it needs underlying trading records—including counterparties, timing, volumes and prices—to challenge Sebi’s market-manipulation allegations.
Sebi argues it must provide only documents relied on for its interim order and says sharing more could harm its ongoing investigation.
Sebi alleges Jane Street affected prices in the NSE Nifty Bank Index to benefit its options positions; earlier 2024 reviews by NSE and Sebi’s surveillance department found no evidence of such influence.
Sebi’s July 3, 2025, interim order barred Jane Street from trading in Indian securities and required it to place 48.4 billion rupees in alleged gains in escrow.
