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.
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.
