The UK's core instant payment system handling bank-to-bank transfers up to £1M, with most payments arriving in seconds. Originally launched with a £10K limit in 2008, it was one of the world's first real-time retail payment systems. Settles via the Bank of England's RTGS system with net deferred settlement. Managed by Pay.UK, the FPS rail also processes standing orders and forward-dated payments, but the data shown here covers Single Immediate Payments only — the real-time component. The New Payments Architecture (NPA) programme is modernising FPS with ISO 20022 messaging.
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.
