Share Market News: A big change has occurred in the Indian stock market, as SEBI, the market regulator, has taken harsh action against the well-known American trading firm, Jane Street. SEBI has charged the corporation with violating market norms through manipulative high-frequency trading methods. According to reports, the business opened big holdings in the Bank Nifty Index's options component and sought to manipulate stock prices in the cash and futures markets to gain an unfair advantage. SEBI has banned Jane Street and asked the company to repay Rs 4,844 Cr, allegedly obtained through illegal means. The prohibition will be in effect until the whole amount is recovered.

SEBI Investigation on Jane Street

According to SEBI’s investigation, Jane Street’s activity during the weekly expiry of index options caused significant market distortions, and harmed investor trust, and market integrity. Despite losses in the futures and cash markets, the company generated a net profit of Rs 36,671 Cr from January 2023 to March 2025, mostly from the options segment. SEBI emphasized that such deceptive practices impair market transparency and declared its commitment to ensuring a fair trading environment. This decisive move reassures investors that SEBI is aggressively preserving their interests and upholding the credibility of India’s financial markets.
