Banks Race to 2027 Deadline for ISO 20022 E&I Migration

Banks are accelerating work to move exceptions and investigations (E&I) flows to the ISO 20022 messaging standard ahead of a 2027 deadline, with readiness ranging from coordinated, multi-year programmes to isolated system fixes. Financial institutions and payments specialists warned that outcomes will vary unless projects align operations, technology and data governance.

Regulators and industry groups require E&I flows to adopt ISO 20022 by 2027. Some firms have launched programmes that link payments operations, IT modernization and data quality initiatives. Other banks are treating the change as a sequence of point upgrades to legacy systems, leaving a wider gap between enterprise-level and tactical approaches as the deadline approaches.

At a recent webinar hosted with RedCompass Labs, panelists including Pratiksha Pathak, head of payments at RedCompass Labs; Bobi Shields-Farrelly, SVP and head of payments operations at PNC; and Sean Hickey, cash management product manager at Mizuho Bank, discussed the operational effects of the transition. They noted that structured ISO 20022 data should make it faster to identify issues across correspondent networks, reduce manual steps and shorten resolution times.

Panelists outlined risks when banks upgrade independently. Changes implemented without an enterprise roadmap can create interoperability gaps, inconsistent data handling and duplicated work across departments and correspondent banks. Those gaps can increase operational risk, raise remediation costs and slow cross-border investigations when message content or handling rules differ.

Regional adoption is uneven. European banks generally show higher readiness, reflecting experience with SEPA and other ISO 20022 initiatives and clearer roadmaps for full E&I migration. North American banks have been more cautious, with many still planning large-scale programmes rather than executing them. Firms in different regions view the 2027 date either as a target for integrated transformation or as a compliance milestone for targeted upgrades.

Panelists recommended treating the E&I transition as a multi-year programme. Key actions identified include strengthening data governance, building shared message validation and enrichment services, and creating monitoring tools that can trace exceptions across correspondent chains. These measures aim to allow structured ISO 20022 data to be consumed consistently across internal teams and external partners.

With preparatory deadlines arriving over the next year and the hard requirement in 2027, banks face a choice between accelerating enterprise-level programmes or continuing incremental fixes. Panelists urged institutions to assess current readiness, map gaps across operations, technology and data practices, and scale solutions that work across correspondent networks.
