Will there be translation rules for ISO 20022 to MT and vice versa? Where can I find these?

Yes. In order to enable standardization and end-to-end straight-through processing, SWIFT together with the CBPR+ working group (represented by the industry) defined a clear set of standard translation rules between ISO 20022 and MT for most of the messages. These have also been applied by SWIFT’s Transaction Manager to avoid misinterpretation and/or divergent adoption of translation rules across banks and/or communities.

To see translation rules, please access SWIFT MyStandards platform, which is available to all SWIFT clients. It is the chosen tool to be used by the community as the primary source for ISO 20022 messages (e.g. CBPR+ Usage Guidelines) and it also gives you access to the Translation Portal where you can test translation rules.
