BIG NSE Update: NSE To Slash Response Time To Nanoseconds From April 11: What Will Change For Investors?

India's capital markets are set for a major technology shift as the National Stock Exchange of India prepares to move its core trading systems to nanosecond response times from 11 April, a step that aims to handle soaring order volumes and maintain competitiveness in an increasingly algorithm-driven environment.

NSE Managing Director and CEO Ashishkumar Chauhan told members of the Association of NSE Members of India that the redesigned architecture is expected to raise trading speed almost 1,000 times from existing levels, which currently stand near 100 microseconds and support roughly 5-6 million transactions each second.

NSE trading technology shift to nanoseconds and ultra-low latency

The planned change means NSE systems will operate at the scale of a nanosecond, or one billionth of a second, marking a sharp fall in latency that could eventually allow almost 100 million transactions per second and place the exchange among a select group of ultra-low latency markets worldwide.

Chauhan highlighted this change in clear terms, saying, "We are going to give you response time in nanoseconds. Your speed is going to increase manifold," signalling to trading members that the infrastructure overhaul is designed for much faster access and execution.

At present, NSE handles high activity with a response time of about 100 microseconds, which allows around 5-6 million transactions per second; after the upgrade, the exchange expects a step change in capacity that is intended to address growing algorithmic participation and rising retail and institutional orders across segments.

The shift to ultra-low latency is closely linked to the growth of algorithmic and high-frequency trading, where even microsecond delays can affect execution quality, price formation, and liquidity, making speed a central factor for participants that depend on rapid order placement and instant access to live market data.

Lower latency systems typically help exchanges match orders faster, support more efficient price discovery, improve management of heavy traffic during peak sessions, and maintain stronger alignment with leading global markets, which is important as international investors and domestic traders both increase their use of automated strategies.

NSE trading technology and expansion of colocation capacity

To support the nanosecond framework, NSE is also expanding its colocation facilities, which permit trading firms to place their servers within the exchange data centre for minimal network delay; existing capacity of more than 2,000 colocation racks is planned to rise to around 4,500 racks in the coming phase.

Colocation continues to be widely used by institutional traders and high-frequency participants that rely on the closest possible proximity to exchange systems for faster access, and Chauhan noted that artificial intelligence is playing a wider role in how technology vendors design trading and analytics tools with greater efficiency and lower cost.

NSE trading technology push and new product roadmap

Alongside the technology changes, NSE is working on an expanded product pipeline that includes electricity futures and more gold-linked instruments, reflecting growing demand among investors and hedgers for additional tools to manage risk and diversify exposure across asset classes beyond the existing equity and derivatives offerings.

The exchange is preparing to introduce 10-gram gold futures, which recently received approval from the Securities and Exchange Board of India, while contracts for difference are also under development, signalling that the platform is aligning its product strategy with changing preferences in both retail and institutional segments.
