The recent regulatory action against Jane Street has stirred conversation around market liquidity, particularly in India’s derivatives segment. The proprietary trading firm, known for its large scale arbitrage and high frequency trading, is currently under the lens of the Securities and Exchange Board of India. SEBI issued an interim order curbing Jane Street’s activity, prompting speculation about how this might affect market depth and turnover. While immediate ripples are visible, experts across the financial community agree that the impact will be short lived.
Jane Street has long been recognized as a major provider of liquidity, especially in the derivatives market. With its algorithmic strategies and rapid fire execution models, it has contributed significantly to smoother trades and tighter spreads. Naturally, any pause or reduction in its participation creates a visible gap. However, data from the Bombay Stock Exchange paints a relatively stable picture. Turnover on expiry days has not seen any dramatic dips. For example, the total derivatives turnover stood at approximately Rs 438.5 lakh crore on July 1, the day the SEBI order took effect, and rose slightly to Rs 461 lakh crore by July 8.
This suggests that other market participants, including institutional traders and retail investors, have started filling the void. A few large institutional brokers noted that although Jane Street’s absence is noticeable, other algorithmic players like Citadel Securities, Optiver, and IMC Trading may soon step in to stabilize trading volumes. In fact, some believe the short term dip in hyperactive trades may be a good thing, allowing markets to breathe and return to more grounded, less volatile movements.
One institutional broker even pointed out that this phase might help bring some rationality back into derivatives volumes. The pace at which trading had been escalating, largely driven by ultra fast strategies, might now be tempered slightly, giving way to more fundamentals driven price discovery.
SEBI, for its part, has maintained that India’s market should never be overly reliant on a single or small group of players. The regulator sees this action as a necessary cleansing step and has expressed confidence in the resilience of the Indian financial ecosystem.
Jane Street was a dominant player, but it was not the only one. Other major global entities such as Flow Traders, Tower Research, Two Sigma, Jump Trading, Goldman Sachs, Hudson River, and DRW are also deeply involved in Indian markets. Experts believe these firms are closely monitoring the situation and may cautiously increase their activity to capitalize on the vacuum left by Jane Street.
Market voices like Angel One’s Chairman Dinesh Thakkar and Zerodha’s CEO Nithin Kamath have also reinforced confidence in the system. Thakkar noted that the influx of retail investors and broader institutional engagement means markets today are far more diversified than in the past. Kamath emphasized that the future performance of F&O volumes will reveal just how dependent the system was on players like Jane Street. Even if there is some lag, he believes the system is equipped to balance itself.
Looking ahead, fund managers expect that while there may be a visible drop in liquidity for the coming week, especially if the SEBI action causes hesitation among other high frequency trading firms, conditions will likely stabilize within a fortnight. The festive season and quarter end financial activity are also expected to boost trading enthusiasm, helping further absorb any liquidity shocks.
Despite this regulatory disruption, market sentiment remains intact. The indices are not expected to swing wildly due to this one factor alone, and broader trends like economic indicators and earnings season will continue to drive directional movement.
As markets evolve and regulations adapt to growing complexities in high speed trading, the Indian financial system is gradually learning to accommodate volatility with resilience. The temporary slowdown may just be a pause before the next phase of disciplined growth.
