Digital Euro Standards Deal: ECB Locks In Open Payment Rails to Break US Card Grip

The European Central Bank has signed cooperation agreements with three European standard-setters to build the digital euro on open, royalty-free technical rails, a move designed to loosen the grip of Visa, Mastercard and global digital wallets on eurozone payments. The 24 April 2026 agreements with the European Card Payment Cooperation (ECPC), nexo standards and the Berlin Group make their existing specifications the backbone of how digital euro transactions will be initiated, accepted and settled once the currency launches.

For the payments industry, the significance is structural rather than symbolic: the ECB has chosen not to build a proprietary stack.

What does the agreement actually cover?

Three standards now sit at the core of the digital euro's technical architecture. ECPC's CPACE standard will handle contactless tap-to-pay transactions via near-field communication between cards, wallets and terminals. nexo standards specifications will connect merchant point-of-sale systems to the back-end infrastructure of payment service providers and acquirers, covering acceptance and cash-machine flows. Berlin Group standards will enable alias-based payments (such as sending to a mobile number), balance checks, reconciliation, and in-app merchant payments on smartphones.

All three specifications are already in commercial use. Berlin Group's API framework underpins roughly 80% of Europe's PSD2-compliant open banking implementations, according to the organisation's own data. CPACE, developed by a six-country cooperative founded in 2020, is already certified by major terminal and card vendors.

Why is the ECB leaning on existing standards rather than building new ones?

Cost and adoption speed. By reusing specifications that merchants, acquirers and terminal manufacturers have already integrated, the ECB avoids forcing the market to rebuild infrastructure from scratch. Terminals certified for CPACE today will not require hardware upgrades to accept digital euro payments at the point of sale.

There is also a strategic rationale. Europe currently has no universally available open standard supported across payment terminals and relies heavily on proprietary rails controlled by international card schemes and global wallet operators. The ECB's framing is explicit: this is about reducing dependency on non-European infrastructure at a moment when payments sovereignty has moved firmly onto the policy agenda.

What does this mean for European payment providers?

A national card scheme, for example, could expand beyond its home market into point-of-sale environments elsewhere in the euro area without requiring new terminal integrations. That removes one of the most persistent barriers to cross-border scaling for domestic European schemes, which have historically struggled to compete with the universal acceptance footprint of Visa and Mastercard.

Piero Cipollone, the ECB Executive Board member chairing the High-Level Task Force on a digital euro, said the open standards would "provide a European free alternative to current proprietary standards, make it easier for new European providers to enter the market and give European payment service providers and merchants the certainty they need to invest, innovate and compete across the euro area."

Markus Schierack, Managing Director of SRC, which acts as Secretariat and Editorial Lead for the Berlin Group, framed the partnership as validation of the open-standards model: "Open standards are the foundation of a competitive and interoperable European payments market."

What still has to happen before any of this goes live?

The legislative piece. The benefits depend on EU co-legislators adopting the digital euro Regulation, which would confer legal tender status and guarantee that the standards apply uniformly across the euro area. Until the Regulation passes, market actors lack the certainty they need to commit significant investment. The ECB has been clear that the preparation phase is advancing on parallel tracks, but issuance cannot proceed without the legal framework.

The standards were selected in consultation with the Rulebook Development Group, which includes market participants, and align with the broader Eurosystem payments strategy. Additional standards may be added over time, subject to ECB Governing Council approval.

How does this fit the broader payments sovereignty debate?

The announcement lands against a backdrop of intensifying European concern about reliance on US-controlled payment infrastructure. Around two-thirds of card transactions in the euro area are processed on international card schemes headquartered outside Europe.

The European Payments Initiative's Wero wallet and various national instant-payment schemes have been positioned as partial responses, but none has achieved the universal acceptance footprint the ECB is now engineering into the digital euro from day one.

By embedding open, royalty-free standards before launch, the ECB is attempting something the private market has not managed on its own: create a default acceptance layer that any European provider can plug into without paying gatekeeper fees.

Why This Matters to FinanceX Readers

This is a sovereignty play dressed as a technical announcement. For investors tracking European fintech, the signal is clear: the ECB intends to lower the barrier to entry for domestic payment schemes and compress the economic moat that international card networks have enjoyed for decades. Expect renewed M&A interest in European acquirers, terminal vendors and scheme operators whose businesses could scale cross-border without the integration tax that has historically constrained them.

For banks and PSPs, the calculus on digital euro readiness just shifted: the integration cost is now bounded by standards most are already running.
