Jane Street Group — alleged index-manipulation scandal in India

In July 2025, Securities and Exchange Board of India (SEBI) issued an interim order banning Jane Street from trading in Indian securities markets, accusing it of manipulating key indices (Bank Nifty / Nifty 50) via coordinated cash, futures and options trades — a complex expiry-day trading strategy. SEBI confiscated ~₹4,843 crore of alleged unlawful gains.
