Banks face 2027 ISO 20022 E&I deadline – who’s ready?

Banks have until 2027 to move exceptions and investigations (E&I) processing to ISO 20022. Readiness varies across the industry: some firms have launched strategic, multi-year roadmaps that align payments operations, technology and data governance, while others are completing system-by-system upgrades or point fixes.

Strategic programmes focus on end-to-end alignment among operations teams, IT systems and data management. Typical tasks include mapping legacy message fields to ISO 20022 formats, updating case-management tools and setting governance rules for data quality and shared semantics.

Structured ISO 20022 messages provide richer, standardized data. Banks using the format aim to identify exceptions more precisely across correspondent networks, reduce manual investigation steps and shorten resolution times. Operational metrics cited for success include lower inquiry volumes, faster end-to-end settlement confirmations and fewer rejections for missing or ambiguous information.

If institutions upgrade independently, interoperability gaps may appear. Different implementations or versions of the standard can create inconsistent data interpretations and duplicated remediation work, and increase exceptions in the short term. Firms also face legacy system compatibility issues, staff retraining needs and the task of enforcing consistent data standards across multiple participants.

Perceptions of the E&I deadline vary by region, but readiness often differs more by institution than by geography. Questions remain about how national market practices will affect timelines and whether Europe or North America will move faster.

An industry webinar in association with RedCompass Labs will address these questions and examine how firms can coordinate across correspondent networks. Panelists include Pratiksha Pathak, 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, global payments expert, as moderator.

Common measures of readiness include a coordinated technology and operations plan, clear data governance, reduced manual case handling and measurable improvements in cross-border resolution times. Many firms remain in early planning stages as the 2027 deadline approaches.
