Digital Euro Cost Study - Additional Information

Additional information supplementing the Digital Euro Cost Study from June 2025

Brussels, 21 April 2026 - Since the publication of the Digital Euro Cost Study in June 2025, the discussion around the digital euro has progressed. Among other developments, a new version of the Rulebook has been published, and additional information has become available. This includes, for example, the ECB's assessment of costs, design assumptions and synergy potential, as well as materials from the various working sessions conducted as part of the "ERPB engagement on digital euro fit in the payment ecosystem". Against this backdrop, the retail banks that participated in the Study have revisited their initial cost estimates, reassessed them against the original design assumptions and the potential for group and market synergies. The results, which confirmed the estimates of the original Study, were laid down in this supplementary paper as a further constructive contribution to the ongoing dialogue.
