Jane Street argued in court that movements in bank stocks did not hinge on its trades. Representing the firm, lawyer Darius Khambata said the index's constituent stocks went up even when Jane Street was selling. He added that withholding documents would "vitiate" the process and run against "natural justice."
The company is asking for redacted counterparty details contained in SEBI's trade logs that were included in the regulator's July interim order. It is also seeking information on SEBI's inter-department communications and whistleblower complaints that led to the creation of an investigation committee. The firm says it needs those records to understand why the watchdog set aside its own internal review, which had previously cleared Jane Street.
Regulatory fights over trading profits can reshape how a market works. Market Briefs covers these disputes free every morning.
Jane Street's appeal is shaping up as a test of SEBI's authority after the July 3, 2025 order and the seizure of 48.4 billion rupees. SEBI has accused the firm of swaying prices of stocks in the NSE Nifty Bank Index, a widely tracked gauge with options tied to it. Despite prior findings from the National Stock Exchange and SEBI's surveillance department that the firm hadn't engaged in market abuse, the regulator restarted its investigation. Jane Street has denied the allegations, deposited the money, and has yet to restart trading in India. The Securities Appellate Tribunal's next hearing is set for Oct. 6.
Regulatory fights can shake sentiment even when the facts are still being argued. If you hold India-focused funds, expect noise around the Oct. 6 hearing and watch how quickly SEBI shares data, because process speed often dictates when capital gets back to work. Big picture, it is a reminder that rulebook risk is real, and it can show up far from Wall Street.
