SEBI Bans Jane Street Over Index Manipulation, Freezes ₹4,843 Crore

Accusing the firm of expiry-day manipulation in Nifty 50 and Bank Nifty options, the interim order grants Jane Street 21 days to respond.

Overview

  • SEBI’s interim directive bars four Jane Street entities—JSI Investments, JSI2 Investments, Jane Street Singapore Pte Ltd and Jane Street Asia Trading—from dealing in Indian securities.
  • The regulator has ordered ₹4,843.57 crore in alleged unlawful gains to be frozen in an escrow account pending further inquiry.
  • The 105-page order alleges Jane Street deployed intraday index manipulation and marking-the-close tactics to influence option settlement prices.
  • Investigators found the firm earned over ₹36,500 crore from expiry-day index-derivatives strategies between January 2023 and March 2025.
  • Jane Street has formally disputed SEBI’s findings and may seek a hearing or file objections within the prescribed response period.
