Official definition

Amount of funds available to cover specified message amount is insufficient.

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.

There were not enough funds to cover the amount. In a payment status report it usually means the ordering customer's account, or the sending bank's settlement account, did not hold enough when the payment was due.

In direct debits it is the classic unpaid reason: the debtor's account could not cover the collection.

What to do

  • For your own payment order: fund the account and send the payment again; check whether any other payments in the same batch failed for the same reason.
  • For a returned direct debit: contact the debtor before you collect again and check how many times the scheme lets you re-present.
