FedNow is not a central bank digital currency. It’s an instant payment/settlement service offered to banks, and will compete with existing services like RTP and Zelle.

Discussion
It’s a digital currency issued by a central bank. Like paper currency, it represents a liability of the central bank. FedNow is just a service the Fed will be paid for. Also like paper currency, it’s a direct relationship between currency holders and the central bank, unmediated by other banks. FedNow is a service for banks.
