The People's Bank of China (PBOC) has issued revised business rules for the Cross-Border Interbank Payment System (CIPS), effective February 1, 2026. The updated regulations now include the Digital Currency Research Institute as a notified entity, reflecting the growing integration of digital currency frameworks within traditional financial systems. The new rules cover on-chain data and settlement methods, supporting real-time gross settlement, payment versus payment (PvP), delivery versus payment (DvP), and cross-border RMB transactions. This update replaces the previous 2018 version and provides a comprehensive outline of the CIPS operational structure, aiming to enhance efficiency and security in cross-border transactions.
