Known for its rigorous hiring process, strong intellectual culture, and cutting-edge trading strategies, Jane Street is not just another Wall Street firm it’s a leader in proprietary trading and global financial markets.

Core Business Model
As of now, SEBI (Securities and Exchange Board of India) has not officially banned Jane Street from operating in India. However, there have been recent reports (as of mid-2024 to early 2025) indicating that SEBI has restricted or flagged certain proprietary trading practices involving foreign algorithmic or high-frequency trading (HFT) firms, which may include Jane Street.
SEBI vs Jane Street What’s the Issue?
Jane Street is a global proprietary trading firm that operates in multiple markets using quantitative algorithms and HFT strategies. They are not retail brokers but trade using their own money.
Why Did SEBI Intervene?
SEBI, the regulatory body of Indian stock markets, is concerned about foreign trading firms using advanced high-frequency algorithms that might:
- Create unfair advantages in the market.
- Disrupt market stability.
- Potentially exploit latency arbitrage (benefiting from small time delays in market data).
Possible Actions Taken by SEBI:
While no official blanket ban has been published (as of July 2025), SEBI is:
- Monitoring foreign algo firms (including Jane Street).
- Potentially restricting their access to Indian exchanges (like NSE, BSE).
- Pushing for greater transparency and pre-approval of algorithms.
How Does It Affect Jane Street?
Jane Street may be:
- Barred or limited from directly participating in Indian exchanges like NSE.
- Asked to register and disclose all trading algorithms used in India.
- Facing compliance checks and restrictions from SEBI’s new frameworks on algo trading.
⚠️ Note: These restrictions only apply to Jane Street’s India operations, not their global trading activities in the US, EU, or other countries.

SEBI’s Concern with Algo/HFT Trading
SEBI has tightened norms for high-frequency and algorithmic trading since:
- Small firms and retail investors feel disadvantaged.
- Some trades were found to “front-run” others.
- Regulatory bodies want a fair and equal playing field.
SEBI’s 2024–2025 Measures on Algo Trading:
- All algos must be pre-approved by stock exchanges.
- Algo orders must be tagged and monitored.
- No unregulated access to co-location facilities for foreign firms.
- Firms must follow stringent compliance norms or face suspension.
What Does This Mean for Traders & Investors?
- Retail investors are protected from being outpaced by foreign HFT firms.
- Indian firms get a more level playing field.
- Foreign quant firms like Jane Street may restructure or reduce Indian market exposure.
Conclusion
While SEBI hasn’t officially banned Jane Street outright, it is taking serious steps to limit the influence of foreign proprietary algo trading in India. This could affect Jane Street’s India operations, but not its global presence. These actions are part of SEBI’s larger push to make Indian markets more transparent, fair, and stable for all investors.
