RTP launched in 2017 and is operated by The Clearing House, owned by the largest US banks. FedNow launched in 2023 and is operated by the Federal Reserve, reaching all 10,000+ US depository institutions. Most US instant payments will flow over both rails depending on the participating banks.
Both rails are 24/7/365, credit-push only, irrevocable, and based on ISO 20022. They are technically interoperable in concept but not connected - a payment must be sent and received on the same network, or routed through a service overlay (like Zelle or a bank's own logic) that picks the rail.
FedNow's main advantage is reach: every US Fed master-account holder can participate, which is critical for community banks and credit unions. RTP's main advantage is maturity - it has years of production volume and is the rail behind many existing instant-pay services.

Community banks, credit unions, and any institution wanting direct Fed-operated reach without TCH membership.
Large banks already on TCH and use cases requiring the larger transaction limit.
This is not an either/or. Treasury and payment teams should connect to both - directly or through a bank-as-a-service provider - to maximize reach. Routing logic picks the rail per transaction based on which rail the receiving bank is on.
Frequently asked
Are FedNow and RTP interoperable?+
Not directly. A FedNow payment must be sent and received on FedNow; same for RTP. Some overlays (Zelle, bank-managed routing) abstract the rail choice from the end user.
Will FedNow replace RTP?+
Unlikely. Both are expected to coexist long-term, with RTP retaining the larger transaction limit and FedNow providing broader institutional reach.
