The Federal Reserve is doing more than adjusting interest rates nowadays.

On Thursday, the Fed announced that its new system for instant payments, the FedNow Service, is now live. Officials said banks and credit unions of all sizes can sign up and use this tool to instantly transfer money for their customers, any time of the day, on any day of the year.

“The Federal Reserve built the FedNow Service to help make everyday payments over the coming years faster and more convenient,” Federal Reserve chair Jerome Powell said in a news release. “Over time, as more banks choose to use this new tool, the benefits to individuals and businesses will include enabling a person to immediately receive a paycheck, or a company to instantly access funds when an invoice is paid.”

To start, 35 early adopting banks and credit unions, as well as the U.S. Department of the Treasury’s Bureau of the Fiscal Service, are ready with instant payments capabilities via the FedNow Service.

In addition, 16 service providers are ready to support payment processing for banks and credit unions.

When fully available, the Fed highlighted instant payments will provide substantial benefits for consumers and businesses, such as when rapid access to funds is useful, or when just-in-time payments help manage cash flows in bank accounts.

For example, officials said individuals can instantly receive their paychecks and use them the same day, and small businesses can more efficiently manage cash flows without processing delays.

Over the coming years, the Fed said customers of banks and credit unions that sign up for the service should be able to use their financial institution’s mobile app, website, and other interfaces to send instant payments quickly and securely.

As an interbank payment system, officials pointed out that the FedNow Service operates alongside other longstanding Federal Reserve payment services such as Fedwire and FedACH.

“The Federal Reserve is committed to working with the more than 9,000 banks and credit unions across the country to support the widespread availability of this service for their customers over time,” officials said.
