On 20 March 2023, SWIFT activated the Cross-Border Payments and Reporting Plus (CBPR+) framework, officially beginning the ISO 20022 era for cross-border payments. Institutions could now send payment instructions using the new MX message format alongside the legacy MT messages, marking the start of the coexistence period.
What Went Live
The CBPR+ go-live enabled ISO 20022 MX messages for the core cross-border payment message types: pacs.008 (customer credit transfer), pacs.009 (financial institution credit transfer), and camt messages for cash management and reporting. SWIFT's central translation facility handled conversion between MT and MX formats, ensuring that an institution sending in MX could reach a counterpart still operating on MT, and vice versa.
Migration Approach
SWIFT adopted a "like-for-like" initial phase: the MX messages at go-live carried essentially the same data as their MT equivalents. The richer data capabilities of ISO 20022 - structured addresses, extended remittance information, and enhanced purpose codes - were available but not yet mandatory. This approach minimized disruption while establishing the new format on the network.
Industry Readiness
At go-live, a significant proportion of SWIFT traffic remained in MT format. Many institutions, particularly smaller banks and those in emerging markets, had not yet completed their internal system upgrades. SWIFT's translation service was designed precisely for this scenario, allowing the migration to proceed gradually without a big-bang cutover.
Significance
The CBPR+ go-live was the culmination of years of planning and represented the beginning of the end for SWIFT's MT message standards, which had been the backbone of international payments since the 1970s. It aligned cross-border messaging with the ISO 20022 standard already adopted by major domestic RTGS systems, creating the foundation for end-to-end structured data in international payment chains.
