The European Central Bank (ECB) is stepping up its efforts to develop its central bank digital currency (CBDC) by launching a call for expressions of interest aimed at euro area merchants. This initiative invites e-commerce and mobile commerce players to participate in a full-scale testing phase scheduled for the second half of 2027. Businesses interested in this voluntary, unpaid program have until October 27, 2026, to submit their applications. The objective is to validate the technical robustness and user experience of the solution, which will be tested in real-world conditions alongside 36 payment service providers, ranging from major banking institutions to specialized fintechs.
This pilot project will focus on a beta version of the digital euro, lacking legal tender status but designed to test the system's scalability. The selection of partner merchants will be rigorously determined by the Eurosystem, which will prioritize the commercial reach and operational maturity of the applicants. Alongside these tests, the institution is relying on a well-defined structure bringing together nineteen national central banks. This experimental phase is crucial for the ECB, which hopes to finalize the design of its digital currency ahead of a potential rollout by 2029, subject to the completion of the European regulatory framework by the end of 2026.
However, this ambition faces a market reality shaped by the rise of euro-denominated stablecoins. While the ECB moves slowly through its institutional timeline, private solutions compliant with the MiCA framework are already capturing significant market share, with issuance volumes exceeding $880 million. Key players such as Circle, with its EURC token, or SG-Forge are already establishing operational digital payment infrastructures. This private competition raises questions about the relevance and strategic positioning of a public CBDC against on-chain alternatives already adopted by businesses for their transactional needs.
Beyond commercial competition, the digital euro project faces persistent skepticism. Recent studies reveal very limited interest from European companies, which struggle to see any added value compared to existing payment systems. Between data privacy concerns and constraints related to holding caps set at 3,000 euros, public acceptance of this instrument remains a major challenge. The ECB will therefore need to demonstrate not only the technical superiority of its project, but also its ability to address real needs in a financial environment where several international central banks have already chosen to shelve their retail CBDC projects in favor of private innovation.
