India’s securities regulator plans to boost its surveillance systems to better detect complex trading strategies after taking action against high-speed trading giant Jane Street Group for alleged market manipulation.

India has barred Jane Street from the country’s financial markets and said it would seize around $570 million that the U.S. securities firm made from allegedly fraudulent trades.

The Securities and Exchange Board of India (Sebi) has recently taken action against the global trading firm Jane Street which has triggered significant conversations around the Indian stock market and how it functions.
