China's Internet Banking Payment System processes 24/7 interbank transfers across the country's massive banking network, operated by the China National Clearing Center (CNCC) under the People's Bank of China. IBPS handles both small-value real-time payments and bulk transfers, complementing the HVPS (high-value) and BEPS (bulk) systems. With China's 1.4B population and rapidly digitising economy, IBPS is one of the highest-volume payment systems globally, supporting online banking, mobile payments, and cross-bank settlement.
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.
