India’s Ban on Jane Street Sparks Debate Over Regulatory Oversight

Indian tax authorities and SEBI are expanding their probe into Jane Street Group, initially charged with price manipulation in NSE’s index, to include alleged tax evasion. SEBI has seized ₹48.43 billion and banned four entities linked to Jane Street, causing a one-third drop in India’s weekly options trading. The regulator claims Jane Street manipulated expiry-day trades for profit, harming retail investors. While Jane Street denies wrongdoing, experts debate whether SEBI can prove intent. The case raises concerns about regulatory oversight and retail investor protection. Jane Street’s reputation may face global impact depending on SEBI’s final order, expected within 8–24 months.
