FedNow

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 [2][6] — 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 [7][8]. 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 [1][8]. 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].
