Is Jane Street Covertly Influencing India's Stock Market

A major regulatory spotlight has turned towards Jane Street, a global trading firm known for its advanced algorithmic strategies. The Securities and Exchange Board of India (SEBI) has launched a probe into Jane Street’s trading activity, particularly in equity derivatives over the last 3 years. The investigation highlights concerns over benchmark index manipulation and has sparked interest in the firm’s operations, earnings, and broader market influence.

Jane Street Explained: Origins and Global Reach

Jane Street is a quantitative trading firm established in 2000 by a group of traders and technologists in New York. It specialises in proprietary trading, with a strong presence across global markets. The firm is widely recognised for its dominance in exchange-traded funds and active participation in equities, bonds, and derivatives.

Jane Street has grown significantly over the years and now employs more than 3,000 professionals across its offices in New York, London, Hong Kong, Singapore, and Amsterdam. Its business model is grounded in data-driven decision making and the deployment of automated trading strategies.

The Size and Scale of Jane Street's Operations

While global figures showcase Jane Street’s remarkable growth, its performance in India has also been substantial. In 2024, Jane Street reportedly earned $2.3 billion in net revenue from equity derivatives trading in India alone. Globally, the firm recorded $20.5 billion in net trading revenue, exceeding the trading revenues of traditional banking giants such as Bank of America and Citigroup.

This scale of profitability reflects Jane Street’s deep integration into global capital markets and its strategic expansion into emerging economies like India.

Legal Battle with Millennium Management and India Connection

In the United States, Jane Street filed a lawsuit against its competitor, Millennium Management and 2 former employees, alleging theft of a confidential trading strategy. Jane Street claimed that this particular strategy was its most profitable and had generated $1 billion in 2023.

Interestingly, during legal proceedings, Millennium’s representatives disclosed that the trading strategy in question was applied in the Indian market. Jane Street further stated that it suffered a 50% decline in profits from this strategy in March 2024, attributing the drop to the unauthorised use of the same strategy by its rival.

Why SEBI is Investigating Jane Street?

The Indian market regulator SEBI is scrutinising Jane Street’s trading activities in the derivatives market. The focus is on the firm’s algorithmic trades in benchmark indices such as the Nifty 50 and sectoral indices like Nifty Bank.

SEBI suspects that certain trades involving rapid reversals and transactions at prices significantly deviating from the market may have created artificial volatility or misleading market signals. These practices raised alarms when other firms flagged unusually high profits generated through such trades, prompting SEBI to act.

Earlier this year, the National Stock Exchange (NSE) had already reviewed trades executed by several high-frequency traders, including Jane Street. SEBI’s intervention follows these preliminary findings, underscoring the seriousness of the concerns.

What Makes India Attractive for Firms like Jane Street?

The surge in interest from global algorithmic traders can be attributed to the rapid rise in equity derivatives trading post the pandemic, largely fuelled by retail participation. This booming segment created lucrative opportunities for firms equipped with fast and complex trading systems.

However, this growth has come at a cost. A study published by SEBI in September 2024 highlighted that 90% of individual traders in the equity futures and options market suffered losses between FY22 and FY24. Total retail losses amounted to ₹1.8 trillion during this period, with ₹61,000 crore lost in FY24 alone.

Meanwhile, proprietary trading firms and foreign portfolio investors, which include Jane Street, posted substantial profits of ₹33,000 crore and ₹28,000 crore, respectively. Notably, much of these profits were attributed to algorithm-based strategies.

SEBI’s Regulatory Response to Retail Investor Losses

In response to the imbalance between sophisticated institutional traders and retail investors, SEBI has taken a series of steps to protect the latter. These include restrictions on weekly options, revisions in lot sizes, and other measures aimed at reducing speculative risk for individual traders.

Conclusion

The investigation into Jane Street is part of a broader initiative by SEBI to ensure fair market practices and to minimise the impact of high-frequency algorithmic trading on less-informed market participants.
