• Can a central bank digital currency preserve user privacy while meeting legal and regulatory obligations?

• How will offline and online transactions differ in terms of visibility for users, banks, and the Eurosystem?

Main Topic

A member of the European Central Bank's executive board recently addressed concerns about privacy in the context of a proposed digital euro. He stated that the design of the digital currency aims to deliver the highest level of privacy achievable with current technology. This assertion is intended to clarify how the digital euro would handle transactional data and who could access it under different circumstances.

For offline transactions, the executive board member explained that payments would occur directly between the payer and the payee. In such cases, transactional details would be available only to those two parties, meaning the central bank — the Eurosystem — would not have visibility into individual offline payments. This model is meant to replicate the privacy characteristics that cash provides, where the exchange of value does not create a record accessible to a central authority.

Online transactions operate under a different set of constraints. According to the ECB official, when payments occur online, the Eurosystem would not be able to identify the individuals involved in the transfer. Identification and customer information would remain with the banks or payment service providers that process and distribute the digital euro. Those intermediaries would therefore continue to hold the identity data and remain responsible for compliance with anti-money laundering (AML) and reporting requirements.

It is important to note that while privacy-preserving features are part of the digital-euro design, they do not remove the currency from the legal and regulatory frameworks that govern other forms of money. Banks and regulated payment providers will retain their existing obligations to monitor transactions for illicit activity and to report as required by law. An ECB spokesperson has emphasized that privacy features are compatible with, but do not override, the rules that apply to all money.

The institutional and political timeline for the digital euro is also shaping how the project will be implemented. The European Parliament adopted its negotiating stance on the regulation earlier in the year, and legislative talks with member states aim for an agreement by the end of 2026. The ECB has already selected a group of payment providers for a 12-month pilot, scheduled to begin in the second half of 2027, with initial issuance targeted around 2029. This phased approach — pilot followed by potential broader issuance — reflects both a technical development path and a need to reconcile privacy assurances with compliance obligations.

Internationally, the approach to privacy in central bank digital currencies (CBDCs) varies. For example, recent U.S. legislation restricts the Federal Reserve’s ability to issue a CBDC without specific congressional authorization through 2030, in part reflecting privacy and policy concerns. That law exempts private, permissionless, and privacy-focused dollar-denominated offerings from the ban, creating divergent regulatory environments for public and private digital money. These differences highlight geopolitical and policy trade-offs between protecting privacy, preserving monetary sovereignty, and preventing illicit finance.

Advocates for a privacy-minded digital euro argue that failing to provide robust privacy protections could push consumers toward private digital payment solutions and stablecoins, which might already offer more privacy or convenience. The ECB board member warned that widespread stablecoin adoption could reduce retail deposits held by European banks, further shifting fees and transaction data away from traditional banking intermediaries.

In summary, the ECB’s public position is that the digital euro will incorporate privacy features to the maximum extent supported by current technology, while still ensuring that regulated intermediaries retain the necessary visibility to fulfill AML and reporting duties. The planned pilot and legislative negotiations will test and refine this balance between privacy and regulation before any broader issuance.

Looking forward, continued research and development in cryptography, privacy-preserving transaction protocols, and secure offline mechanisms will be central to delivering a CBDC that meets privacy expectations while satisfying legal obligations. Areas worth exploring further include advanced zero-knowledge proofs, secure multi-party computation, and usable offline payment technologies that minimize data leakage.

Policymakers and technologists will also need to collaborate on governance frameworks that clearly define roles and responsibilities for central banks, commercial banks, and payment providers. Such frameworks should balance individual privacy, financial integrity, and operational resilience. Subtle emphasis on these priorities — privacy, compliance, and technical robustness — will guide practical implementations and public trust.

Finally, cross-jurisdictional coordination and standards development could reduce fragmentation and enhance interoperability between different digital-money systems. This will help ensure that privacy protections are meaningful in practice and not simply theoretical, while enabling lawful cross-border payments and compliance with global AML norms.
