Overview

The FedNow Service is an instant-payment rail built and operated by the U.S. Federal Reserve that enables participating depository institutions to clear and settle payments in near real-time, 24 hours a day, every day of the year. It went live on July 20, 2023 1. FedNow provides interbank clearing and settlement so that funds transfer "from the account of a sender to the account of a receiver in near real-time and at any time, any day of the year" 1. It uses the ISO 20022 messaging standard 2 and is intended as a neutral platform on which financial institutions and their service providers build instant-payment products for consumers and businesses.

History

FedNow is operated by the Federal Reserve as a Federal Reserve service for depository institutions 1. The Federal Reserve announced the detailed design of a 24x7x365 interbank settlement service with clearing functionality to support instant payments in August 2020 3, confirmed a July 2023 launch window in March 2023 4, and the service went live on July 20, 2023 1. It is the first instant-payments infrastructure developed and operated by the U.S. central bank, offering real-time gross settlement to eligible depository institutions nationwide 5.

Technical specification

FedNow runs on the ISO 20022 messaging standard, chosen because of broad industry adoption and "the benefits of its highly structured data" 2. The Federal Reserve states the service "uses a variety of ISO message types, including for customer credit transfers, requests for payment and interbank liquidity transfers, as well as FedNow system and account reporting messages" 2. In practice this maps to the standard instant-payments ISO 20022 message set:

  • pacs.008 — FI-to-FI customer credit transfer; the message that results in settlement of funds between financial institutions 6.
  • pacs.002 — payment status report providing an immediate response and status for each message, carrying acceptance or reject reason codes 6.
  • pain.013 / pain.014 — Request for Payment (creditor payment activation request) and its status report; a receiver responds with pain.014 carrying a status such as RJCT (rejected) or ACTC (accepted) 6.

The standard's structured data supports straight-through processing, the exchange of detailed remittance information alongside a payment, and a reduction in errors 2. Settlement is individual, immediate and irrevocable, contrasting with the batch model of ACH and the legacy Fedwire window 5.

Transaction limits. At launch the maximum credit-transfer value was $500,000, with a default of $100,000 that institutions could raise up to the ceiling 7. The ceiling was later raised to $1 million, and on September 9, 2025 the Federal Reserve announced an increase of the network transaction limit to $10 million, effective November 2025 7.

Use cases

The Federal Reserve frames FedNow as a flexible, neutral platform supporting "a broad variety of instant payments" 1. The higher transaction ceilings position it for higher-value use cases such as corporate treasury, payroll, vendor/supplier payments and real-estate transactions 7. The service also supports a Request for Payment (RfP) message flow, letting a biller send a structured request that the payer approves and pays from their banking app 26 — a basis for bill pay, account-to-account funding and consumer-to-business payments.

Implementations

FedNow itself is a closed interbank network reached through a financial institution or an authorized service provider; the Federal Reserve does not publish an open encoder/SDK repository. There is no public reference implementation. Integration is via ISO 20022 message exchange documented in the Federal Reserve's FedNow technical and ISO 20022 readiness materials 2; third-party processors and core-banking vendors provide connectivity.

Comparison

FedNow and The Clearing House's RTP network are the two real-time, ISO-20022, credit-push interbank rails in the United States, and both now carry a $10 million per-transaction ceiling 78. The principal differences are operator and reach: FedNow is operated by the Federal Reserve and launched in 2023, while RTP is operated by the privately owned The Clearing House and launched in 2017 18. The Fed's role gives FedNow access to the full base of institutions that hold Federal Reserve accounts, complementing rather than replacing RTP. A rail-agnostic QR layer such as the ASC X9 Payment QR Code effort is designed to sit above both, routing a single scanned code over FedNow, RTP, ACH or push-to-card.

Fun facts

  • FedNow is the first instant-payments system built and operated by the U.S. Federal Reserve, settling each payment individually and irrevocably at any hour of any day 5.

Status

Active. FedNow had more than 1,400 participating organizations across all 50 states as of the September 2025 limit-increase announcement 7. Settled-payment volume exceeded one million payments in Q1 2025 and grew further in Q2 2025 5, and the network ceiling rose to $10 million in November 2025 7.
