Banks race to meet ISO 20022 E&I deadline by 2027

Banks are working to move exceptions and investigations (E&I) processing to the ISO 20022 messaging standard by 2027, but readiness across the industry is uneven. Some firms have launched multi-year programs that link payments operations, technology and data governance; others are completing tactical upgrades to individual systems.

The change requires banks to use structured ISO 20022 data in exception handling and investigation workflows for cross-border and correspondent payments. The structured format includes richer remittance fields and standardized message elements that can be read consistently across systems.

Institutions that are pursuing strategic roadmaps are aligning middleware, reconciliation platforms and operations training to test end-to-end workflows ahead of the deadline. Banks taking a tactical approach are updating specific platforms or interfaces without a coordinated data governance plan.

Industry practitioners warned about risks when participants upgrade systems independently. Potential problems include mismatched data fields, inconsistent handling of exception codes, longer testing cycles and increased operational friction when message formats do not interoperate. Those outcomes can produce fragmented workflows and additional manual intervention during investigations.

Measures of success for the E&I change include faster detection and routing of exception cases, fewer manual investigations, clearer audit trails and reduced settlement risk in cross-border flows. The ISO 20022 data model supports more detailed remittance information, which can enable better automated matching and simpler investigation steps.

Adoption pace varies by region. Some payment systems and infrastructures in Europe have already moved further with ISO 20022 on core rails, while some North American banks report slower uptake because they manage multiple legacy platforms and wide correspondent networks. Regulatory timelines and the design of local clearing systems affect how urgent the transition is for each institution.

A webinar hosted in association with RedCompass Labs will review readiness benchmarks, common pitfalls and practical steps for meeting the 2027 E&I migration. The session will feature 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 as moderator.

ISO 20022 is a global messaging standard that uses structured, XML-based formats to carry more detailed payment data than many legacy standards. The E&I component covers how banks manage queries, chargebacks and repairs when payments fail or need extra information. Moving these workflows to ISO 20022 requires changes across technology stacks, operational processes and correspondent relationships.
