SEBI has barred US-based Jane Street Group from participating in the Indian stock market and ordered it to disgorge unlawful gains of ₹4,843 crore for allegedly manipulating stock indices through derivative positions.

India's markets regulator has widened an investigation into alleged market manipulation by U.S. securities trading firm Jane Street to include other indexes and exchanges, a source familiar with the matter said.

India’s stock market regulator has banned Jane Street from dealing securities in the country, accusing the New York-based trading firm of a “sinister scheme” to manipulate derivatives markets. The Securities and Exchange Board of India said its decision to limit Jane Street’s access to India’s securities markets stemmed from a months-long investigation.
