Bank of England Endorses Harmonized Cross-Border Payment API Standards

On December 19, 2024, the Bank of England formally welcomed recommendations from the Committee on Payments and Market Infrastructures (CPMI) API Panel of Experts aimed at harmonizing cross-border payment APIs. The CPMI panel's report, originally published in October 2024, outlined standards and best practices for APIs to enhance interoperability across jurisdictions and payment systems. The Bank of England's endorsement signals strong regulatory support for API-standardized infrastructure that can reduce friction, cost, and settlement times in international payments.

For BaaS providers and embedded finance platforms, harmonized API standards lower integration complexity and open opportunities for scalable cross-border payment products. The recommendations align with the G20 roadmap for enhancing cross-border payments and represent a concrete step toward a globally interoperable API layer for financial services. Banks, payment service providers, and fintech companies building cross-border infrastructure are expected to benefit from the clearer standards framework.

No specific compliance deadlines were announced, but the endorsement establishes a normative direction for the industry.
