Harmonised ISO 20022 Data Requirements for Cross-Border Payments Updated
Summary
The CPMI published an updated report on harmonised ISO 20022 data requirements for cross-border payments, building on the October 2023 joint CPMI-PMPG publication. The update incorporates standardisation and regulatory developments since 2023, provides clarifications on areas where market participants sought guidance, and presents an expanded data model in a separate technical annex aligned with the ISO 20022 release schedule. The CPMI and PMPG developed harmonised requirements that remain neutral to specific solutions and allow flexibility for adoption until the end of 2027, with a joint panel established to support maintenance and encourage global adoption during the G20 cross-border payments programme.
“ISO 20022, an international financial messaging standard, enables more consistent and structured data, supporting the objectives of faster, cheaper, more accessible, and transparent cross-border payments.”

What changed
The CPMI published an updated version of its harmonised ISO 20022 data requirements for cross-border payments, amending the October 2023 joint CPMI-PMPG publication. The updated report reflects standardisation and regulatory developments over the intervening period, provides clarification on areas where market participants sought further guidance, and restructures the data model into a separate technical annex to facilitate more regular updates aligned with the ISO 20022 release schedule. While these harmonisation requirements are not regulatory mandates, the CPMI encourages their adoption to reduce fragmentation and improve interoperability. The requirements will be maintained at least until end-2027 under the G20 cross-border payments programme.
Public and private sector payment system operators and participants implementing ISO 20022 should review the updated data model in the technical annex and assess whether implementation practices align with the clarified harmonisation requirements. Financial institutions involved in cross-border payment operations may benefit from engaging with the joint panel established by the CPMI to support maintenance and promote global adoption. The flexibility period extending to end-2027 provides a defined window for implementation alignment, though early adoption is encouraged to realise network effects and improve cross-border payment quality.

- Technical annex
The CPMI's harmonised ISO 20022 data requirements for cross-border payments (harmonisation requirements) are a key milestone under the G20 roadmap for enhancing cross-border payments. ISO 20022, an international financial messaging standard, enables more consistent and structured data, supporting the objectives of faster, cheaper, more accessible, and transparent cross-border payments. Variability in ISO 20022 implementation, however, could limit its benefits, making alignment crucial to achieving the roadmap's objectives.
To address these challenges, the CPMI and the Payments Market Practice Group (PMPG) developed harmonised requirements, published in October 2023. These requirements focus on critical measures, remain neutral to specific solutions, and allow flexibility for adoption until the end of 2027. The updated version of the report takes into account standardisation and regulatory developments since 2023, provides clarification where market participants had sought further guidance, and sets out the updated and expanded data model in a separate technical annex. This approach allows for more regular updates of the data models in line with the ISO 20022 release schedule, if and as needed.
The harmonisation requirements offer guidance for public and private sector payment system operators and participants to implement ISO 20022 consistently. Realising their benefits depends on widespread and consistent implementation, which could foster a network effect and broader adoption. While not regulatory requirements, the CPMI encourages adoption to reduce fragmentation and improve interoperability in cross-border payments.
The CPMI will maintain the harmonisation requirements at least until the end of 2027, during the G20 cross-border payments programme. To support their maintenance and encourage global adoption, the CPMI has established a joint panel comprising members from the ISO 20022 global market practice groups. The updated report has benefited from panel members' inputs.
