The Federal Reserve's instant payment service enabling US banks and credit unions to send and receive payments in seconds, 24/7/365. Launched in July 2023, FedNow is the first new Fed payment rail in 50 years and aims to democratise instant payments by giving all 10,000+ US depository institutions direct access (unlike the private-sector RTP). Supports credit transfers up to $500K with plans to add request-for-payment and other features. Note: FedNow shows extreme growth rates as it scales from a low base — value jumped 35x in Q3 2024 as larger institutions onboarded, which is typical for newly launched payment systems.
Mexico's Sistema de Pagos Electrónicos Interbancarios is one of the world's earliest 24/7 real-time payment systems, operated directly by the central bank (Banxico). SPEI processes both high-value and retail payments with no maximum transaction limit, settling in real time through Banxico's accounts. It supports CLABE (standardised 18-digit account numbers) and has been extended with CoDi, a QR-based overlay for merchant payments. Note: SPEI data includes both immediate and scheduled transfers on the same rail, as Banxico does not separately report real-time vs deferred transactions.
