Official definition

Regulatory Reason

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 payment was stopped for a regulatory reason the bank does not explain further, typically a sanctions, embargo or compliance decision.

Banks are often not allowed to say more, so the code is deliberately vague.

What to do

  • Do not resend or split the payment to get around the decision.
  • Involve your compliance team and ask your bank what information it needs. Keep a record of the case.
