For years the digital euro has been Europe's most-discussed currency that does not exist. Conceived as a public, electronic form of cash — central-bank money you could hold on your phone, alongside the notes and coins in your pocket — it has lived mostly in consultations, working groups and slide decks. This month it took two concrete steps toward becoming real.
On 11 July, the European Commission published the long-awaited final version of its regulatory framework for the currency. Days later the ECB released version 0.91 of its digital euro "rulebook," the technical scheme setting out how banks, merchants and payment providers would actually plug in. Neither is the finish line. Together they mark the moment the project shifted from arguing about whether to build a digital euro to specifying how.
The ECB finished its two-year "preparation phase" at the end of 2025 and has moved into the next stage: building infrastructure, testing with the market, and refining the rulebook using feedback from a large consultation run through 2025. Its timeline is now reasonably concrete. A 12-month pilot is pencilled in for the second half of 2027. A first actual issuance could follow in 2029 — but the ECB is explicit that this rests on an assumption it cannot control: that the European Parliament and member states pass the enabling regulation at some point in 2026.
That is the catch. The ECB can design the plumbing, but only the EU's co-legislators can authorise the euro to exist in digital form. And that is where the easy part ends.
Three arguments have dominated, and none is resolved. The first is privacy. The ECB insists a digital euro would not let it track individual payments and points to an offline mode meant to work like cash; critics, and some MEPs, want that guarantee written hard into law rather than left to the central bank's assurances. The second is the holding limit — a cap on how many digital euros any one person could keep, floated at somewhere around €3,000. Set it too high and savers might pull money out of commercial banks in a crisis; set it too low and the currency is barely useful. The third, closely related, is what the whole thing does to Europe's banks, which fear losing deposits and being reduced to processing a currency issued over their heads.
Beneath the technical detail sits a strategic motive that has only grown louder. European officials increasingly frame the digital euro as a matter of sovereignty: most card payments in the euro area run through American networks such as Visa and Mastercard, and the rise of dollar-backed stablecoins has sharpened the worry that Europe's payments could end up dependent on infrastructure it does not control. A public digital euro is Brussels' answer — a homegrown rail that works everywhere in the bloc.
The digital euro is no longer a question of if but of when, and on current plans "when" means the back end of the decade at the earliest. That gap between political ambition and delivery date is itself the story: the technology is largely ready, but the currency is hostage to a legislative process that must reconcile privacy campaigners, nervous banks and twenty-seven governments. The July milestones matter because they move the fight onto firmer ground — there is now a real rulebook and a real draft law to argue over. But anyone expecting to spend digital euros soon should read the ECB's own timeline closely: a pilot in 2027, issuance no earlier than 2029, and even that conditional on lawmakers doing their part first. Europe has decided it wants public money for the digital age. It has not yet decided the terms.
