How are financial institutions and other market participants preparing for the migration of Exceptions & Investigations (E&I) to ISO 20022? DPS investigated this question in spring 2026 through a market survey of financial institutions, SWIFT bureaus, data centres, and software and solution providers. The results were recently published in the latest issue of ibi insights.
The analysis reveals a mixed picture. 44% of respondents plan a full transition to ISO 20022-based E&I messages by November 2026. A quarter are pursuing a phased migration approach, in which passive reachability will be ensured first, with native processing to be implemented at a later date. A further 25% do not currently have a firm timetable.

Nor is there a uniform vision emerging with regard to technical implementation. More than half of the participants (56 per cent) are opting for camt-based integration, whilst 31 per cent had not yet finalised their target technical architecture at the time of the survey. API-based integration models played a minor role, accounting for 13%.

A look at the responses from financial institutions reveals a somewhat clearer picture than in the market as a whole. Half of the institutions surveyed were planning a complete migration by November 2026. At the same time, however, one in five institutions had not yet finalised its migration plans. When it came to selecting the future E&I solution, in-house developments dominated (50%), whilst 30% opted for external software solutions.
The results illustrate that market participants are approaching the E&I migration with different strategies. Whilst some had already finalised their target architecture, others were still in an early planning or evaluation phase. For the first time, the survey thus provides a reliable insight into the migration planning of various market players.
Our payments expert Tobias Münsterberg has provided a comprehensive analysis of the results and the current SWIFT roadmap in a specialist article for the latest issue 1/2026 of ibi insights by ibi research. In it, he explains the technical changes brought about by the new case-based E&I model, the introduction of structured investigation use cases, and the implications for processes and system landscapes in the payments sector.
