Jane Street Group Prohibited: The Securities and Exchange Board of India (SEBI) has prohibited four entities of the US-based Jane Street Group from participating in Indian securities markets, citing extensive fraud and manipulation within the derivatives sector.

In a 105-page interim ruling, SEBI revealed a complex trading strategy focused on manipulation during expiry days. The regulator stated that Jane Street consistently affected the prices of Bank Nifty and Nifty 50 index components through aggressive intraday trading, thus distorting options pricing to achieve substantial profits.
