Banks race to meet 2027 ISO 20022 E&I deadline

Banks must shift exceptions and investigations (E&I) workflows to ISO 20022 by 2027, and institutions are taking different paths to meet the deadline. Some firms have begun multi-year payments transformation programmes that align operations, technology and data governance. Other organisations are making point upgrades to messaging, reconciliation and case-management systems without a single, coordinated redesign.

Structured ISO 20022 messages provide more consistent data fields than legacy formats. Payments teams say richer message semantics should make it easier to locate where a payment failed across correspondent chains, reduce manual checks and shorten resolution times. Consistent data elements can also reduce time spent reformatting messages when payments pass through multiple banks and local market infrastructures.

A webinar hosted by RedCompass Labs brought industry practitioners together to assess readiness. Participants included Pratiksha Pathak, SVP and head of payments at RedCompass Labs; Bobi Shields-Farrelly, SVP and head of payments operations at PNC; Sean Hickey, cash management product manager at Mizuho Bank; and Scott Hamilton, a global payments and liquidity expert, who moderated the session. Panelists framed the transition as an operational and data-governance task as well as a technology upgrade.

Panelists identified several operational risks if banks upgrade systems independently. Fragmented approaches can produce incompatible message handling and inconsistent exception routing, increasing reconciliation workloads when correspondents interpret ISO fields differently. Uncoordinated projects can also duplicate spending, stall integrations with partners and raise operational risk as legacy systems run alongside new platforms. Without clear data governance, banks may struggle to map new ISO fields to existing workflows, slowing anticipated efficiency gains.

Payments specialists outlined indicators of success: predictable, end-to-end exception handling that reduces manual casework and increases straight-through processing; shared interpretation of ISO 20022 fields among correspondent banks; and consolidated case-management platforms that ingest structured messages. They recommended clear governance to ensure message elements feed automated resolution processes.

Regional differences in readiness are visible. European banks generally report higher readiness levels, reflecting earlier adoption of ISO 20022 in some market infrastructures and corporate payment corridors. In North America, readiness is more varied: some large banks and service providers have launched structured programmes, while others progress through phased, tactical changes. Those differences affect cross-border flows because correspondent banks in different regions must align message usage and operational responses to work together.

Panelists advised banks to inventory existing E&I workflows, map dependencies on correspondent and vendor systems, invest in data governance and case-management platforms that accept ISO 20022 messages, and conduct interoperability testing with partners and market infrastructures. With the 2027 deadline approaching, banks are at different stages of readiness and continue to balance coordinated transformation against shorter-term upgrades.
