The digital euro and what it means for correspondent banking

A retail CBDC is taking shape — slowly, and by design

The European Central Bank has spent several years working through what a digital euro would actually be. An investigation phase examined the design questions — privacy, offline use, how it would sit alongside cash and existing bank accounts — and since November 2023 the project has been in a "preparation phase", the stage where the technical and rulebook work needed to eventually build it gets done.

It is worth being precise about what that phase is and is not. It is not a rollout. A digital euro cannot go live without enabling legislation, and the regulation the European Commission proposed to create that legal basis is still making its way through the European Parliament and the Council.

Until co-legislators agree a final text, there is no confirmed launch date, and the project's own timeline has already shifted more than once. Any bank planning around a fixed date is planning around a number nobody has actually set.

Why correspondent banking should still be watching

A retail digital euro, if it arrives, is a consumer and merchant payment instrument — it is not a wholesale settlement asset, and it does not replace the correspondent banking relationships that move money between institutions across borders.

That distinction matters, but it doesn't make the project irrelevant. Central bank digital currencies are being explored by multiple jurisdictions in parallel, and SWIFT has been running experiments and sandbox trials looking at how separate CBDC networks — and the existing correspondent banking rails — could interconnect. A landscape with several CBDCs and a large installed base of conventional payment infrastructure is far more likely than one rail displacing everything else, so interoperability becomes the practical problem worth solving.

For banks and PSPs, the more immediate questions are second-order: a widely held digital euro could pull some balances out of commercial bank deposits, change how payments get routed at the point of initiation, and shift where intermediaries add value. None of this is settled — the shape of the final scheme, including any holding limits or remuneration rules, could still change materially.

What to do instead of waiting

Rather than waiting for certainty, track the legislative process and the interlinking work in parallel, and start to map where a digital euro would touch existing payment flows and correspondent relationships if and when it does arrive.

That's the kind of scenario planning Run Ventures does with banks working through correspondent banking strategy today — not because the digital euro is imminent, but because the institutions that have already mapped the dependencies won't be starting from zero when the legislation finally lands.
