The Securities and Exchange Board of India (SEBI) has issued a stern interim order against global trading firm Jane Street Group and its associated entities, barring them from participating in the Indian securities market. The action, taken on July 3, follows allegations of serious violations of market regulations.
According to SEBI, the Jane Street entities made unlawful gains estimated at ₹4,843 crore. The regulator has instructed the group to deposit this entire amount into an escrow account with a scheduled commercial bank in India. Additionally, SEBI directed banks to freeze any debit transactions without prior approval.
As per the order, Jane Street and its affiliates are prohibited from buying, selling, or dealing in securities, directly or indirectly, until further notice. Preliminary findings suggest the firm engaged in suspicious trading behavior that potentially resulted in market manipulation and breaches of regulatory norms.
Jane Street Group is a prominent proprietary trading firm known for high-frequency and algorithm-driven trading strategies. The company operates globally across a range of asset classes, including equities, bonds, ETFs, and derivatives. In India, it has notably expanded its footprint in the derivatives market.
The SEBI order alleges that Jane Street and its related entities deployed trading strategies intended to manipulate the Nifty 50 index — India’s benchmark stock index. The regulator claims these strategies artificially influenced market movements and led to unfair profits, which have now been impounded.
The regulatory probe was initiated following media reports in April 2024, which highlighted concerns about proprietary trading strategy misuse in the Indian options market. Headlines such as “Jane Street-Millennium Suit: ‘Secret’ Strategy Concerns India, Hearing Reveals” and “Ex-Jane Street Trader Pillories Claims He Stole Trade Secrets” triggered SEBI’s preliminary investigation into the trading practices of Jane Street and its affiliates.
The 105-page interim order from SEBI accuses Jane Street of executing aggressive, large-scale, and time-sensitive trades—specifically during the expiry sessions of Bank Nifty and Nifty index options. These trades, conducted over 18 trading days, allegedly disrupted market integrity and were designed to manipulate prices to the firm’s advantage.
