Jane Street made ₹36,500 crore profit by manipulating Bank Nifty trades. SEBI’s July 2025 order exposes high-frequency strategy behind the index rigging.

What Is Jane Street and Why Is It in Indian Financial Headlines?

In a stunning turn of events, Jane Street, a global trading giant, has been barred from Indian markets by the Securities and Exchange Board of India (SEBI). On July 3, 2025, SEBI released an interim order accusing the firm of manipulating Bank Nifty and Nifty index levels, resulting in unlawful gains of ₹4,843.5 crore. This comes after Jane Street reportedly made a staggering ₹36,500 crore in profit through high-frequency trades on Dalal Street.

Let’s explore how this Wall Street firm entered Indian markets, what strategy it used to allegedly “game” the system, and why SEBI’s crackdown is shaking investor confidence.

📈 Who is Jane Street? A Global Quant Giant in Indian Markets

Founded in 2000, Jane Street is a New York-based proprietary trading firm known for its dominance in ETF arbitrage, options trading, and high-frequency strategies. With offices in New York, London, Hong Kong, Singapore, and Amsterdam, the firm is considered a major player in global financial markets.

🔍 Key Facts about Jane Street:

• Founded: 2000
• Headquarters: New York, USA
• Specialization: Algorithmic & High-Frequency Trading
• Global Presence: Operates in 40+ countries
• Employees: Over 2,000 globally

While Jane Street has long thrived in the West, its aggressive foray into Indian derivatives markets has now led to serious regulatory action.

🧮 Jane Street’s Strategy: How It Allegedly Manipulated Dalal Street

According to SEBI’s 100+ page interim order dated July 3, 2025, Jane Street and its affiliates employed a repeatable, manipulative strategy targeting index expiry days.

💡 Alleged Trading Pattern:

• Morning:
  • Massive purchase of Bank Nifty futures & equities
  • Simultaneous aggressive selling of Bank Nifty options
• Post-Noon:
  • Sudden heavy selling of futures contracts
  • Resulted in lower closing index levels

🧾 Example — January 17, 2024:

• Bought Bank Nifty Futures worth ₹4,370 crore
• Sold Bank Nifty Options worth ₹32,115 crore
• Later sold Futures worth ₹5,372 crore
• Net Profit: ₹673.4 crore (after a ₹61.6 crore loss in futures & cash)

This strategy allegedly distorted price discovery, especially during monthly expiry days, leading to what SEBI terms as “market manipulation“.

⚖️ Legal Violations: Breaking SEBI’s PFUTP Norms

Jane Street’s tactics allegedly violate the Prohibition of Fraudulent and Unfair Trade Practices (PFUTP) under Indian securities law. Despite being under investigation since early 2025, the firm reportedly continued with similar strategies on:

• May 15, 2025
• May 29, 2025
• June 27, 2025

This repeated behavior strengthened SEBI’s case for a blanket market ban.

📉 Wider Concerns: Algorithmic Trading & Market Integrity

This case has reignited concerns over algorithmic and high-frequency trading in Indian markets. While these tools offer efficiency, unchecked access by foreign firms can lead to:

• Artificial index moves
• Unfair profits
• Erosion of investor trust

SEBI is now expected to review norms for Foreign Portfolio Investors (FPIs) and algo trading rules to prevent future manipulation.
