November 2026 release
On Nov. 16, 2026, the Fedwire® Funds Service intends to implement the changes detailed below to ensure interoperability with modifications that Swift® and CHIPS® (peer operator) will make. Please review each change and required actions to ensure your institution knows how to avoid business disruptions.
| Description of change | Action required |
|---|---|
|
Replacement of current unstructured postal address format (three lines of 35 characters each) with a hybrid postal address format for all persons/entities and financial institutions. The hybrid postal address format requires at least the town name and country. (Additional information may be provided in other structured address elements and/or two free-formatted text lines of 70 characters each.) |
|
| Introduction of a pattern representing the character set at the XSD schema level for text elements (the permissible set of special characters are not changing). |
|
| Enhancements to the investigation messages (camt.110/camt.111) to enable better structuring of frequently used investigation use cases. |
|
| Enhancements to the FedPayments® Manager – Funds application (e.g., Create Payment Return feature for past messages, response feature for incoming return requests, drawdown requests, and investigation requests). |
