Jane Street Faces Market Manipulation Charges, Hires Khaitan & Co. for Defense

Renowned American High-Frequency Trading (HFT) entity, Jane Street, has appointed eminent law firm Khaitan & Co. to represent it amidst charges of suspected market manipulation, as put forth by well-informed sources. Last week, the Securities and Exchange Board of India (SEBI) provisionally claimed in a directive that Jane Street manipulated the Bank Nifty and Nifty indices over a span of 24 months by maintaining larger trading positions than other stakeholders in their cash & derivative constituents.

SEBI posits that this maneuver granted Jane Street the power to accrue unauthorised profits upwards of ?4,844 crore through trades in weekly Bank Nifty and Nifty options. The financial watchdog currently investigates Sensex options. Anticipations suggest that Jane Street may soon close the case and potentially agree to the penalty demanded by the SEBI, stated an informed high-ranking official.

Fundamentally, Jane Street faces two alternatives – either dispute SEBI’s preliminary directive or acknowledge it. Opposing the order would necessitate Jane Street to raise the dispute in the Securities Appellate Tribunal (SAT), and depending on the arbitration of the SAT, possibly carry it forward to the highest court – Supreme Court. Conversely, acknowledging the decree infers the payment of the stipulated sum and continuing with market trades, while still maintaining the right to legal recourse given the ongoing SEBI investigation.

SEBI’s order alludes to a significant incident that transpired on January 17, 2024, which marks the weekly expiry of Bank Nifty options. The index declined by 3.2%, opening at 46,574, following lackluster quarterly results announced by HDFC Bank. Jane Street reacted by purchasing Bank Nifty index futures and constituent stocks worth a whopping ?4,370 crore, pushing the index to rally and peak at 47,212.75, engendering an aura of recovery.

As the index rallied, the value of call options went north while the put options were on the decline. The SEBI affirms that Jane Street went on to divest from pricier call options whilst buying cheaper put options from other market participants at this stage, culminating in a total bearish stance on Bank Nifty options worth ?32,114.96 crore.

In the subsequent phase, Jane Street purportedly liquidated its positions, causing the index and its components to tumble. This, in turn, inflated the value of the puts that were procured excessively, while devaluing the disposed-off calls. As a result, Jane Street managed to amass ?735 crore in options that day as the Bank Nifty spiraled downwards by 4.28%, closing at 46,064.45.

The regulator alleges such tactics facilitated Jane Street to realize an unlawful profit of about ?4,844 crore over 21 days spanning from August 2023 to May 2025. Pursuant to the allegations, SEBI has instructed the confiscation of the contentious gains and prohibited Jane Street from dealing in the capital market until the proceeds are stashed in an escrow account.

SEBI further shed light on the fact that the Jane Street entities have harvested a cumulative profit of ?36,502.12 crore from January 2023 to March 2025 by exploiting their trading strategies. Following the SEBI directive, Jane Street clarified its stance through an internal communication to its personnel.

The communication revealed the firm’s discontentment over its characterization and confirmed that it will be drafting a formal retort to SEBI’s allegations. Jane Street specifically rebuffed the accusation pertaining to January 17, 2024, maintaining that the so-called manipulative strategy was, in fact, a widespread practice instituted to reconcile a substantial price deviation between the Bank Nifty index options and the price benchmarks implied by its stocks on the day in question.

Regardless of the circumstances, this case embodies a critical juncture in the interplay between regulatory bodies and high-profile trading firms. Besides, it also underscores the need for clearer guidelines surrounding high-frequency trading and market manipulation to maintain an even playing field.

The transparency and fairness of financial markets, which a large number of investors depend on, are at stake here. Consequently, investment entities globally will be following this case with avid interest, as the final decision could have sweeping ramifications on how high-frequency trading is surveyed and regulated.

The charges faced by Jane Street and the corresponding legal process that unfolds can serve as a significant deterrent for potential manipulative actions. As investors, market observers, and other industry stakeholders await a resolution, the outcome is likely to shape the future discourse surrounding high-frequency trading and market manipulation.

While the potential impact of these developments on India’s investment community is considerable, the global implications cannot be stressed enough. Other markets worldwide may adjust their regulatory approaches based on the outcome of this case, further underlining its importance. Undeniably, the future development and regulation of financial markets, particularly in the high-frequency trading segment, will be significantly influenced by the final judgment.
