In a landmark enforcement action, the Securities and Exchange Board of India (SEBI) has barred the U.S.-based Jane Street Group and its associated entities from India’s securities markets. The July 3, 2025, interim order alleges manipulation of index derivatives during expiry-day sessions—specifically in Bank Nifty and Nifty 50. SEBI has impounded ₹4,843 crore in alleged unlawful gains.
This development sends a clear message: market integrity is non-negotiable.

🧠 How the Alleged Manipulation Worked
Jane Street is accused of manipulating the market through a pump-and-dump-like strategy:
- Inflating Index Stocks: Large, coordinated buy orders pushed up Bank Nifty constituent prices on expiry mornings.
- Profiting on Options: Simultaneously holding short positions on inflated options led to gains as prices corrected.
- 21 Expiry Days: The scheme was allegedly repeated over 21 expiry sessions between 2023 and 2025.
This action distorted the natural price discovery mechanism, misleading both retail and institutional investors.
SEBI Observation: “Such coordinated activity was not based on fundamentals or technical rationale.”
