Kiffmeister’s #Fintech Daily Digest (20231104)*

ECB pushes back on commitment to immediate availability of offline digital euro

The regulation proposed by the European Parliament and Council requires both online and offline digital euro payment transactions to be available on the first issuance of the digital euro. However, the European Central Bank (ECB) says that “further testing by the Eurosystem will be necessary to guarantee that all relevant digital euro models offer sufficient security and maturity… Enshrining the ECB’s intent in a legally binding provision will constrain its capacity to react to the higher level of uncertainty that the offline digital euro model involves, as well as to react to exceptional circumstances necessitating an imminent issuance of any available model. If trade-offs that have not yet been identified arise, postponing the overall issuance of the digital euro would be the only option available to the ECB… For these reasons, the ECB invites the co-legislators to consider the imposition of a requirement upon the ECB to deliver both online and offline versions of the digital euro, coupled with a ‘best efforts’ provision under which the ECB would make available both online and offline models as of the first issuance of the digital euro.” [Read more at the ECB]
