SEBI barred Jane Street Group entities from accessing the Indian securities market and directed the impounding of Rs 4,844 crore in alleged unlawful gains from the group.
Jane Street earned Rs 43,289 crore in profits through trading in index options on Indian exchanges, leading to SEBI's enforcement action restricting their market participation.
The saga involved lawsuits in the US, SEBI examining trading activity for potential market abuse, and SEBI's interactions with Jane Street regarding trading practices, leading to a settlement between Jane Street and Millenium in December 2024.
Despite NSE's caution letter and SEBI's observations, Jane Street continued large cash-equivalent positions in index options, leading to SEBI's interim order restraining them from market access over alleged unlawful gains.
