The Federal Reserve has announced plans to add more operating days. The Fedwire Funds Service and the National Settlement Service (NSS) will now include Sundays and holidays during the week. This move is an important step in modernizing U.S. high-value payment processing. It shows progress toward a more continuous banking system and real-time payments. 

Today, Fedwire and NSS operate Monday through Friday, excluding holidays. Under the new plan, both systems will operate from Sunday to Friday. Fedwire will have 22 hours of service each day, while NSS will have 21.5 hours. 
 

The Federal Reserve has indicated that implementation will begin no earlier than 2028, with additional guidance to follow. 
 

Even though it is years away, this announcement sets the stage for future progress. It could lead to real 24x7x365 settlement in the U.S. 

Fedwire is the backbone of large-value payments in the U.S., supporting trillions in daily interbank and corporate transfers. Expanding the settlement window fundamentally changes how banks think about liquidity, operations, and customer expectations. 
 

For financial institutions, the implications include: 
 

• Liquidity management: Banks must rethink how they use reserve balances. They also need to manage intraday liquidity over a longer work week. 

• Operational readiness: Weekend and holiday processing will require adjustments to staffing, monitoring, and exception-handling frameworks. 

• Client service and competitiveness: Institutions that adopt extended settlement capabilities early will have an edge. They can offer clients faster access to funds and better flexibility. 
   

This expansion is not just about longer hours. It aims to create a more connected financial system. This system will always be active and will better match the fast pace of global trade. 

While the benefits are clear, the path forward brings operational and technical complexity. Smaller financial institutions, in particular, may face challenges around staffing costs, technology upgrades, and adapting internal risk frameworks.
 

Coordination across the ecosystem will also be critical. Not all counterparties, clearinghouses, or correspondents may use the same expanded window at first. This could limit early liquidity benefits.
 

Despite these hurdles, the long-term opportunity is significant. A broader settlement window means improved efficiency, reduced bottlenecks, and a more resilient payments system overall. 

At Finzly, we see this as a defining moment in the evolution toward real-time, always-on banking. The expansion reinforces what we’ve long believed: the future of payments depends on flexibility, visibility, and unified infrastructure. 
 

Whether it’s new Fedwire rules, extended processing windows, or ISO 20022 messaging, a modern, always-certified platform handles it seamlessly. Automatic updates keep everything compliant, taking the pressure off financial institutions and keeping operations running smoothly. 
 

With Finzly, institutions can: 
 

• Gain full liquidity visibility across multiple rails and settlement windows 

• Automate reconciliation and exception handling to minimize manual oversight 

• Extend value to clients through flexible payment timing and transparency 

• Prepare for continuous operations with modular upgrades rather than disruptive system replacements 
   

By using an open, API-driven system, banks can keep up with innovation. Old infrastructure won't hold them back. 

Although the expanded window won’t arrive until at least 2028, preparation should begin today. Leading institutions can use this time to strengthen infrastructure and position themselves ahead of regulatory deadlines. 
 

Key steps include: 
 

1. Assess your current wire and liquidity systems to ensure they can support near-continuous operation. 

2. Review policies and staffing models for weekend and holiday operations. 

3. Engage technology partners early to align system roadmaps and ensure interoperability. 

4. Educate clients and teams on how extended settlement hours will improve service and efficiency.
    

By being proactive, banks can use this change to meet new standards and stand out in the market. 

The growth of the Fedwire and NSS settlement window is a step toward a better and stronger payments system. It shows that the U.S. financial system is moving toward being available all day, every day. This goal matches Finzly’s mission to help banks work in real time.
