Recently, the Securities and Exchange Commission of India issued an interim regulatory notice prohibiting US quantitative trading giant Jane Street Group from entering the local market until further notice, and has seized the company's capital of 48.4 billion rupees. According to SEBI, these funds were “illegal proceeds” obtained by the company in connection with “heinous market manipulation”. This is the harshest measure SEBI has taken against foreign trading companies in recent years. SEBI said its investigation found that Jane Street manipulated stock indices through derivatives trading, causing losses to retail investors on counterparties. Notably, driven by the good performance of India's major stock indexes, retail investors have flocked to the market in recent years, further driving India into the derivatives market with the largest contract trading volume in the world. Individual investors are heavily involved in derivatives trading, and the liquidity of options is even higher than spot, which forms an important background for Jane Street to manipulate the market.
