Banks face serious challenges in processing payments if they fail to meet the deadline for the adoption of ISO 20022 messages for Swift cross-border payments and cash management messages, according to banking and financial IT sources.
The adoption of the ISO 20022 standard for Swift cross-border payments and reporting messages must be completed by November 2025, at which point category 1, 2 and 9 FIN messages will be retired from the many-to-many closed user group known as the FIN service.
