Sebi’s 100-page interim order authored by whole-time member Ananth Narayan G. offers a look into the inner workings of the US-based trading firm’s strategy, and how Jane Street allegedly distorted the Bank Nifty and Nifty 50 to profit from options trades.

India's market regulator said it had barred U.S. trading company Jane Street from accessing the local securities market, after an investigation into its alleged market manipulation through positions taken in equities derivatives.

The U.S. trading firm’s entities are “further prohibited from buying, selling or otherwise dealing in securities, directly or indirectly.”
