Ananth Narayan: The Ex-Trader Leading SEBI’s Toughest Market Probe Yet

Ananth Narayan, a senior official at the Securities and Exchange Board of India (SEBI), has become the unlikely face of one of the most high-profile crackdowns in India’s financial history. A former derivatives trader turned regulator, Narayan led the investigation into Jane Street, a US-based proprietary trading firm accused of manipulating India’s stock markets.

Why Did SEBI Ban Jane Street?

In July 2025, Narayan signed SEBI’s explosive interim order banning Jane Street from participating in Indian markets and freezing Rs 4,843 crore (about $570 million) in alleged illegal profits. The order accused the firm of using high-frequency and expiry-day trading strategies to distort the Bank Nifty and Nifty indices—strategies that reportedly caused significant losses for retail investors.

Jane Street, founded in 2000, is a global trading powerhouse known for its algorithmic and quantitative trading, with offices in New York, London, Hong Kong, Amsterdam, and other financial centres.

In the order, Narayan didn’t hold back. He wrote: “The JS Group is not a good faith actor… The faith of millions of small investors and traders can no longer be held hostage to the machinations of such an untrustworthy actor.” The strongly worded indictment grabbed international attention and sent a clear signal that India is taking a tougher stance on foreign market participants.

Who Is Ananth Narayan?

Narayan stands out within SEBI for his deep roots in trading. Before joining the regulator in 2022, he held senior roles at Deutsche Bank, Citigroup, and Standard Chartered, working across currencies, rates, and derivatives. He is the only SEBI board member with hands-on experience in complex financial instruments—a background that proved crucial in understanding and decoding Jane Street’s sophisticated strategies.

According to a Bloomberg report, Narayan’s expertise allowed SEBI to connect the dots across various departments and identify a pattern of trades that consistently profited at the expense of retail participants. His insight has previously been sought by the Reserve Bank of India (RBI) to better understand market dynamics.

Narayan’s path to SEBI began in Kolkata, followed by engineering at IIT Bombay and an MBA from IIM Lucknow. After two decades in the financial industry, he shifted to academia and policy, and eventually to market regulation. Known for his precision and cautious approach, he reportedly keeps a sign in his office that says: “First, do no harm.”

Despite his serious public persona, Narayan has a personal side too. According to Bloomberg, he’s a fan of Texas Hold’em poker and occasionally plays with former school friends.
