NSE Chief Warns of AI Cyber Threats and Quantum Risks as Market Cap Crosses ₹460 Lakh Crore

National Stock Exchange of India (NSE) Managing Director and CEO Ashish Kumar Chauhan has called on brokers to urgently strengthen their cybersecurity defences against artificial intelligence-based attacks. Speaking at the Association of NSE Members of India's (ANMI) 16th Annual Capital Market Convention in Mumbai, Chauhan noted that financial institutions in the United States and Japan have recently faced sophisticated cyber threats.

Highlighting international incidents, Chauhan pointed out that Japan declared a national emergency over cyber hacking two weeks prior, while American banks reported AI-based agentic attacks on their infrastructure. To address these vulnerabilities, he urged ANMI to establish a dedicated task force to help member brokers build robust cyber resilience. He also warned of future risks from quantum computing, which could potentially compromise existing cryptographic frameworks, including SSL protocols.

The security warnings arrived alongside data on the expansion of India's capital markets. The country's listed market capitalisation has crossed ₹460 lakh crore, a figure larger than the combined credit and balance sheet of the entire Indian banking system. According to the NSE, listed market capitalisation has grown at a compound annual growth rate (CAGR) of 17 per cent over the past three decades, starting from ₹4 lakh crore in 1994.

Retail and individual participation has expanded significantly. NSE's reach currently extends across more than 99 per cent of India's PIN codes, accounting for over 37 crore registered investor accounts and 13.6 crore unique individual investors. Individual investors, through direct holdings and mutual funds, hold 19.3 per cent of the NSE-listed market capitalisation. This holding grew from ₹7.9 lakh crore in March 2014 to ₹90.3 lakh crore as of June 2026, marking an annualised growth rate of 31 per cent since April 2020. Maharashtra currently leads all states with over two crore unique registered investors.

Chauhan noted that India's current per capita income stands at approximately $3,000, and the nation must reach $25,000 to $30,000 to attain developed-nation status under the Viksit Bharat 2047 target. Alongside equities, the NSE has expanded its product offerings into equity derivatives, currency, commodities, electricity derivatives, and Electronic Gold Receipts, which commenced trading in May 2026. Corporate Bond Index Futures have also received basic regulatory approval following the Union Budget announcement.

Furthermore, Chauhan commended recent regulatory reforms introduced by SEBI Chairman Tuhin Kanta Pandey. These include narrowing the technical glitch framework to relieve roughly 60 per cent of trading members from its scope, extending reporting windows from one hour to two, and consolidating reporting onto a single platform.

In financial year 2026, the NSE conducted over 17,800 investor awareness programmes, engaging 9.3 lakh participants. The Investor Protection Fund corpus is currently maintained above ₹3,000 crore, while the Core Settlement Guarantee Fund stands at ₹13,500 crore as of September 2026.

"As the Indian capital markets scale rapidly, touching ₹460 lakh crore with massive retail participation, technology infrastructure and security must evolve at the same pace. Ashish Kumar Chauhan's warning regarding AI-driven cyber threats and quantum computing risks is a timely reminder for financial institutions and fintech startups alike. Building institutional resilience and proactive cybersecurity frameworks is no longer optional; it is fundamental to safeguarding investor trust and ensuring the long-term stability of India's financial ecosystem." — Dr. Shishir Gupta, Founder & CEO, StartupLanes
