Sebi barred Jane Street entities from the securities markets and directed the group to disgorge unlawful gains of Rs 4,843 crore for allegedly manipulating stock indices through positions taken in the derivatives segment.
The regulatory action comes after an extensive investigation into alleged manipulation of the Indian stock market through index derivatives, particularly Bank Nifty options, which earned the company massive profits of over Rs 36,500 crore between January 2023 and March 2025.
Between January 2023 and March 2025, Jane Street entities made over Rs 43,289 crore in profits from index options, particularly Bank Nifty (BANKNIFTY) using various strategies that allegedly manipulated markets. These profits were partly offset by losses in other segments like stock futures and cash equity, resulting in a net gain of Rs 36,502 crore.
In a 105-page order, Sebi highlighted two key manipulative strategies used by Jane Street to allegedly trick the Indian markets — ‘Intraday Index Manipulation Strategy’ and ‘Extended Marking the Close Strategy’.
