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.
Japan's domestic interbank clearing network, one of the oldest electronic payment systems in the world, connecting over 1,000 banks and financial institutions. Originally a batch-processing system, Zengin was upgraded to 24/7 real-time operations in 2018 via the "More Time System" extension. Operated by the Japanese Bankers Association with settlement through the BOJ, it handles the vast majority of Japan's domestic credit transfers. Note: data includes all Zengin transactions (both real-time and batch-processed), as the system does not separately report its 24/7 instant component.
