DTCC Expands Clearing Services to 24×5

DTCC Expands Clearing Services by extending the operating capabilities of its market infrastructure to support a wider range of trading activity. Through its subsidiary NSCC, the organization now provides clearing services on a near-continuous 24×5 schedule, enhancing accessibility for global market participants. The new framework operates from Sunday at 8:00 p.m. ET through Friday at 8:00 p.m. ET, supporting overnight trading activity across Alternative Trading Systems (ATSs) and exchanges.

The development responds to increasing global demand for broader access to U.S. financial markets. As investors across different regions seek greater flexibility beyond traditional trading sessions, NSCC has moved to support activity across multiple time zones while maintaining efficient post-trade processing. Consequently, market participants can now benefit from enhanced access to U.S. equities throughout the trading week. Moreover, the extended schedule marks an important advancement for the U.S. equities market.

NSCC can now apply its central counterparty guarantee immediately to eligible transactions executed during expanded trading hours. This capability helps market participants manage risk more effectively while promoting confidence in market operations. Brian Steele, Managing Director and President of Clearing & Securities Services at DTCC, described the launch as a major milestone for the industry. He noted that the organization has strengthened access to U.S. markets for investors worldwide while continuing to uphold the risk management standards and operational resilience that support market stability. 

Over the past year, DTCC worked closely with exchanges, ATS operators, clients, and other industry stakeholders to prepare for the transition. The organization conducted extensive testing, operational planning, and industry coordination to ensure a seamless implementation process. Furthermore, DTCC opened its testing environment in January 2026 and required all users of UTC real-time messaging services to validate the necessary system changes. All participating firms completed testing successfully before the official launch. 

Steele also emphasized that DTCC’s collaboration with clients and industry partners played a critical role in preparing the market for this transition. As a result, firms can now operate more confidently in an increasingly connected global trading environment. The latest enhancement builds on operating-hour expansions introduced in September 2024. While ATS platforms have already utilized those extended clearing windows, exchanges are expected to introduce longer trading hours later in 2026, alongside planned operating-hour extensions from Securities Information Processors, further advancing the modernization of U.S. market infrastructure.
