New Delhi, 4 July
Markets regulator Sebi has barred US-based Jane Street Group from the securities markets and directed the group to disgorge unlawful gains of Rs 4,843 crore for allegedly manipulating stock indices through positions taken in derivatives segment.
This could be the highest disgorgement amount ever directed by the Securities
and Exchange Board of India (SEBI).
In its interim order, the regulator has debarred JSI Investments, JSI2
Investments Pvt Ltd, Jane Street Singapore Pte Ltd, and Jane Street Asia
Trading - entities collectively referred to as the Jane Street Group -- from
trading until further notice, while continuing its investigation.
Established in 2000, Jane Street Group LLC is a global proprietary trading firm
in the financial services industry. It employs more than 2,600 people across
five offices in the US, Europe, and Asia, and conducts trading operations in 45
countries.
The Jane Street (JS) Group has come under Sebi's scrutiny for allegedly
manipulating index levels in the stock market to earn illegal profits,
primarily through the highly liquid Bank Nifty and Nifty index options
segments.
An investigation by Sebi revealed that over 21 expiry days between January 2023
and May 2025, the group executed large trades in the underlying cash and
futures markets to influence index movements and profit from massive positions
in the options market.
Two key strategies were identified-- one involved buying heavily in Bank Nifty
stocks and futures in the morning and selling them aggressively in the
afternoon to create a softer close, while the other involved concentrated
selling or buying in the last two hours of the expiry day to sway index levels.
These actions helped the group earn illegal profits of about Rs 4,843 crore,
even as they incurred smaller losses in cash and futures trades, the regulator
said.
Sebi also noted that between January 2023 and March 2025, the JS Group recorded
substantial trading activity across various segments of the market. The group
made gains of Rs 44,358 crore from index options trading, which formed the bulk
of their profits.
However, these were partially offset by losses of Rs 7,208 crore in stock
futures, Rs 191 crore in index futures, and Rs 288 crore in the cash market.
After accounting for all gains and losses, the JS Group reported a net total
profit of Rs 36,671 crore during this period, Sebi noted.
The case stems from media reports in April 2024, which suggested that Jane
Street and its related entities may have used unauthorised proprietary trading
strategies in the Indian options market.
Sebi noted that the JS Group continued to carry out suspicious trading
activities, mainly near market closing on expiry day, by making large and
aggressive trades to unfairly influence the index, even after receiving a
warning in February and making promises to the NSE to stop such practices.
"Such egregious behaviour, in clear disregard/ defiance of the explicit
advisory issued to them by NSE in February 2025, amply demonstrates that unlike
the vast majority of Foreign Portfolio Investors and other market participants,
JS Group is not a good faith actor that can be, or deserves to be, trusted.
"In the face of such a strong prima facie case that allowing the JS Group
to continue as before may severely compromise investor protection on an
extraordinary scale, Sebi has a duty to directly intervene," Sebi added.
Accordingly, Sebi said, "the total amount of unlawful gains earned by the
JS Group from the alleged violations, Rs 4,843.57 crore, shall be impounded
jointly and severally."
The entities have been "restrained from accessing the securities market
and are further prohibited from buying, selling or otherwise dealing in
securities, directly or indirectly."
Additionally, banks where the entities are holding accounts have been directed
to ensure that no debits are made, without Sebi's permission, except for the
purpose of complying with this order.
