BIS Bulletin  |  No 49  |

Key takeaways

  • Interoperability among payment systems – as the foundation for enhancing cross-border payments – requires technical, semantic and business system compatibility so that end users can seamlessly transact with each other across systems.
  • Public and private sector options in pursuing cross-border payment system interoperability can be illustrated using four stylised models, ordered in increasing complexity and cost but also greater efficiency – a single access point, bilateral link, hub and spoke or a common platform.
  • The BIS Innovation Hub is putting theory into practice with several innovative projects to foster interoperability across the four stylised models.
  • An ambitious, multi-year G20 programme to enhance cross-border payments is under way.
