China Scrutinizes Foreign ETF Trading Following Jane Street India Probe
Chinese regulators are examining foreign firms' participation in the $859 billion ETF market, focusing on Jane Street Group following its India regulatory troubles. UBS paused some Jane Street trades as a precautionary measure, though Jane Street accounts for less than 2% of China's ETF trading. The firm faces market manipulation allegations in India, where it generated $4.3 billion in trading revenue between January 2023 and March 2025 before ceasing operations.

Chinese regulators are scrutinizing foreign firms' participation in the country's $859 billion exchange-traded fund market, with particular focus on Jane Street Group following the firm's regulatory challenges in India. The examination seeks to understand trading patterns in China's fast-growing ETF industry amid concerns about market manipulation practices.
Regulatory Scrutiny and Market Position
Jane Street was the biggest foreign ETF market maker through China's qualified foreign investor program as of June 30, despite accounting for less than 2% of overall ETF trading in mainland China. The regulatory queries have prompted precautionary measures from major brokers operating in the Chinese market.
| Foreign ETF Market Makers in China: | Ranking |
|---|---|
| Jane Street Group (US): | Largest |
| Optiver (Amsterdam): | Second |
| Susquehanna International Group (US): | Third |
| Hudson River Trading (US): | Fourth |
Impact on Trading Operations
China's regulatory queries led UBS Group AG to pause some trades from Jane Street via the qualified foreign investor program late last year as a precautionary measure. UBS accounted for a relatively small portion of Jane Street's China ETF transactions before the pause, and the move did not impact Jane Street's other strategies for China.
Jane Street stated that the firm "is conducting business as usual with its counterparties globally, including UBS, across asset classes." There is no indication that trading relationships among Jane Street's peers have been impacted by Beijing's queries, and no firm is accused of any wrongdoing.
India Market Manipulation Case
The Chinese scrutiny follows Jane Street's ongoing legal battle in India, where the firm faces market manipulation allegations. In July, India's securities regulator accused Jane Street of using its financial and technological capabilities to influence price action in futures and cash markets to favor its index option positions.
| India Case Details: | Information |
|---|---|
| Trading Revenue (Jan 2023-Mar 2025): | $4.30 billion |
| Escrow Amount Required: | $570 million |
| Appeal Hearing Date: | January 19 |
| Current Trading Status: | All activity ceased |
Jane Street has denied the allegations and is awaiting the next step in its India case. The Securities and Exchange Board of India lifted the temporary trading ban after the company complied with an order to put $570 million in escrow.
Market Sensitivity and Foreign Participation
The increased scrutiny underscores China's sensitivity to stock market performance, particularly given the market's dominance by retail investors and susceptibility to volatility. Beijing has historically used various regulatory measures and state-owned investment fund interventions to manage market stability.
Some of the world's largest firms have entered China's ETF market in recent years as these investment vehicles gain popularity. However, official real-time activity data remains limited, with Bloomberg Intelligence calculations based on semi-annual financial reports that ETFs must file disclosing their top 10 holders.
Strategic Adjustments
Following its reduced exposure in India, Jane Street has increased trading activities in other markets, including US Treasuries, interest rates, and ETFs across Asia. The firm's revenue generation from China operations remains undisclosed, though its relatively small market share suggests limited direct impact from the current regulatory examination.
