Official definition

Specified message amount is an non processable currency outside of existing agreement

Definition from the ISO 20022 External Code Sets, 2Q2026 (published 28 Aug 2026).

What it means in practice

In a pacs.004 payment return, a return reason code explains why funds that were already settled are being sent back. It sits in TxInf/RtrRsnInf/Rsn/Cd, and bank statements (camt.053, camt.054) repeat it in RtrInf/Rsn/Cd.

The currency cannot be processed under the agreement in place, for example a currency the receiving bank does not clear, or a currency the account cannot hold.

What to do

  • Ask the beneficiary which currencies their account receives, or pay in the account currency and let the beneficiary bank convert.
