The Digital Euro: Legal and Policy Foundations for Europe's Central Bank Digital Currency (CBDC)

Introduction: Europe’s Monetary System Meets the Digital Age

With the rise of private digital currencies, stablecoins, and crypto-assets, central banks worldwide are accelerating efforts to modernize money. In Europe, the European Central Bank (ECB) is actively developing a Digital Euro—a central bank digital currency (CBDC) that would be legal tender throughout the eurozone.

The European Commission published its legislative proposal for the Digital Euro in June 2023, with parliamentary discussions progressing into 2025. If adopted, the Digital Euro would complement—not replace—cash, offering citizens a digital form of public money issued and guaranteed by the ECB.

This article explores the legal architecture, policy motivations, privacy debates, and market implications of Europe’s potential digital currency revolution.

What Is the Digital Euro?

The Digital Euro would be:

Issued by the ECB and national central banks of the Eurosystem,

Available to natural persons, businesses, and governments,

Free to use for basic personal payments,

Accessible via smartphones, cards, or other interfaces,

Usable both online and offline, with instant settlement.

Importantly, the Digital Euro would not be a cryptocurrency or decentralized asset. It would be a centralized, fiat-backed currency with a 1:1 parity to physical euros.

Legal Basis: Strengthening the Euro’s Sovereign Role

The legal proposal is based on Article 133 TFEU and amends the existing Regulation (EU) No 974/98 on the introduction of the euro.

The Digital Euro would be:

Legal tender across all eurozone countries, with the same status as cash,

Subject to mandatory acceptance rules (with some exemptions for micro-entities, religious beliefs, etc.),

Governed under EU-level harmonized legislation, rather than left to fragmented national implementation.

This gives the Digital Euro a strong legal backbone, unlike private digital payment systems or stablecoins.

Why the EU Is Creating a Digital Euro

1. Monetary Sovereignty

With Big Tech platforms offering private digital payment solutions (e.g., Apple Pay, PayPal, Diem/Libra proposals), the ECB wants to ensure that public money remains relevant and competitive.

2. Financial Inclusion

The Digital Euro could provide universal access to secure, no-fee digital payments, especially for the unbanked or underserved.

3. Resilience and Autonomy

In an era of geopolitical fragmentation and sanctions, Europe aims to reduce dependency on non-EU payment systems, enhancing economic sovereignty.

4. Innovation and Competition

A programmable, interoperable digital euro could stimulate fintech development and enhance cross-border payment efficiency—particularly within the EU’s Single Market.

Privacy and Surveillance: A Legal and Political Flashpoint

A major concern in public debates is user privacy. Will central banks monitor every transaction? Will citizens lose their financial anonymity?

The legal proposal addresses this by:

Ensuring offline payments offer cash-like privacy (no central tracking),

Requiring strict limitations on data use even for online payments,

Providing legal guarantees under GDPR, and oversight by independent data protection authorities,

Allowing pseudonymized transactions unless required for anti-money laundering (AML) compliance.

Still, privacy watchdogs and civil society groups demand:

Clearer safeguards against mass surveillance,

Transparency on technical standards,

Sunset clauses and audit mechanisms to prevent overreach.

Role of Private Sector: Wallets, Interfaces, and Value-Added Services

The Digital Euro proposal promotes public–private collaboration:

The ECB provides the core infrastructure and settlement layer,

Intermediaries (banks, fintechs, e-wallet providers) handle user interfaces, compliance, customer onboarding, and added features.

This avoids direct account-holding by the ECB, preserves two-tier monetary systems, and supports market competition.

Private players may also develop programmable payment features, such as conditional payments, subscriptions, or escrow services—though the Digital Euro itself is not programmable money in the sense of “smart contracts” within the base layer.

Anti-Financial Crime Compliance

The Digital Euro will be subject to EU AML and counter-terrorism financing (CTF) rules. Key features include:

KYC checks by intermediaries (banks, PSPs),

Real-time monitoring for online transactions,

Offline payment limits to balance privacy with risk (e.g., capped at €200–€500),

Reporting obligations for suspicious activity.

To address these challenges, Europol and EBA may play a role in standard-setting and enforcement coordination.

Potential Risks and Criticisms

Despite its promise, the Digital Euro faces several concerns:

Disintermediation of banks if users shift deposits to CBDC holdings en masse,

Monetary policy transmission effects, especially during crises,

High implementation costs for infrastructure and cross-border integration,

Digital exclusion risks, especially among elderly or rural populations,

Uncertainty over legal recourse in fraud or technical failure cases.

The ECB plans a multi-year pilot phase, focusing on scalability, security, and inclusion before large-scale rollout.

Conclusion: A Turning Point in European Monetary Law

The Digital Euro is more than a payment tool—it represents a legal innovation at the intersection of monetary policy, digital sovereignty, and consumer rights. If successful, it will:

Redefine how public money circulates in a digital economy,

Provide a EU-native alternative to private and non-EU platforms,

Position the euro as a competitive global currency in the digital age.

Whether the project succeeds will depend not just on technical design, but on public trust, legal clarity, and democratic oversight. Europe’s first digital currency must work for people, not just policy goals.
