Executive briefing: The Federal Reserve announced that Fedwire Funds Service ISO 20022 implementation is scheduled for . Participants must support ISO 20022 messages (e.g., pacs.009, pacs.008) and update validation, reconciliation, and fraud controls before cutover.

Key risk themes

  • Payment rejection risk. Non-compliant formats or missing mandatory data elements could cause rejected wires on cutover.
  • Operational readiness. Interface changes span core banking, AML/OFAC screening, and reconciliation engines that must be regression tested.
  • Counterparty coordination. Correspondent banks and service bureaus need aligned deployment windows and message specifications.

Operational priorities

  • Message standards. Implement ISO 20022 schemas, market practice guides, and mapping from legacy FIN/MT formats.
  • Testing. Complete end-to-end connectivity testing with the Fed testing environment, including negative scenarios and screening integrations.
  • Cutover governance. Freeze changes near 10 March 2025, confirm rollback options, and coordinate business continuity plans.

Enablement moves

  • Publish a client advisory summarizing the March 2025 timeline and data element impacts for corporate wire customers.
  • Update sanction screening and AML rulesets to use enriched ISO 20022 fields (LEIs, UETRs, structured addresses).
  • Train operations and treasury staff on new investigation flows using ISO 20022 reference identifiers.
