Banking Law and Digital Euro Governance in Spain

Introduction

The digital euro is a proposed central bank digital currency for the euro area. It would be electronic public money issued by the Eurosystem and available to individuals and businesses for payments. For Spain, the digital euro would not be a separate national currency and would not be issued independently by the Banco de España. It would form part of the single monetary system governed by the European Central Bank (ECB), the national central banks of the Eurosystem, European Union legislation, and Spanish banking and payment law.

A digital euro would complement cash and commercial-bank money rather than automatically replace them. Its purpose is to preserve access to public money in a digital economy, strengthen European payment autonomy, support innovation, and maintain confidence in the euro. However, its introduction raises major governance questions: who decides whether it is issued, what role Spanish banks will perform, how privacy will be protected, how limits on holdings will work, and how financial stability will be preserved.

Legal and Regulatory Framework

Under Articles 127 and 128 of the Treaty on the Functioning of the European Union, the ECB and national central banks form the European System of Central Banks. The ECB has authority over euro-area monetary policy, while euro banknotes are issued within the Eurosystem. The digital euro would therefore require a European legal basis and institutional coordination rather than a unilateral decision by Spain.

The ECB’s Governing Council directs the technical preparation of the project. The Banco de España participates in the Eurosystem and would contribute to implementation, supervision, communication, payment-system integration, and domestic operational arrangements. Spanish banks and payment service providers would probably act as the main customer-facing intermediaries. They could provide digital-euro wallets, onboarding, customer support, authentication, merchant services, anti-fraud tools, and compliance checks.

The European Commission proposed a Digital Euro Regulation in 2023. The proposal seeks to establish the digital euro as legal tender, ensure broad acceptance, protect access for citizens, and preserve a high level of privacy. However, a digital euro cannot be issued merely because technical work is complete. Final legislative approval at European Union level is necessary before a formal decision on issuance can be taken.

Spain’s Law 6/2023 on Securities Markets and Investment Services, Law 10/2010 on anti-money laundering, payment-services rules, consumer-protection requirements, and data-protection law would remain relevant. The digital euro would not be a crypto-asset, a stablecoin, or private electronic money. It would be a direct liability of the Eurosystem. Nevertheless, banks distributing it would still need to comply with customer due diligence, cybersecurity, operational-resilience, complaint-handling, and fraud-prevention obligations.

The Digital Operational Resilience Act, known as DORA, is especially important. It requires financial entities to manage information and communication technology risk, test operational resilience, report serious ICT incidents, and control third-party technology providers. A digital-euro system would need very strong resilience because widespread payment disruption could affect consumers, merchants, banks, and public confidence.

Key Issues and Principles

Institutional independence is essential. The ECB must be able to perform its monetary-policy functions without political instruction from national governments. Spain may influence legislation through European institutions, and the Banco de España participates in Eurosystem governance, but digital-euro monetary decisions cannot become a tool of domestic political policy.

Privacy must be balanced with financial-crime prevention. A digital euro should not create unnecessary surveillance of ordinary transactions. At the same time, banks and public authorities must be able to prevent fraud, money laundering, terrorist financing, and sanctions evasion. The governance model must define which data are held by intermediaries, which data are accessible to the Eurosystem, when authorities can obtain information, and how access is independently supervised.

Financial stability requires safeguards. If customers could move unlimited funds from bank deposits into digital euros, banks could lose stable funding and face greater run risk during stress. Holding limits, remuneration rules, and automatic “waterfall” or “reverse waterfall” mechanisms may therefore be used to limit excessive migration from bank deposits.

Universal access is a public-interest objective. The digital euro should be usable by people without advanced smartphones, bank accounts, or high digital skills. Offline functionality, accessibility tools, basic accounts, and support through supervised intermediaries are important for Spain’s older population, rural communities, and digitally excluded customers.

Intermediaries need fair incentives. Spanish banks may incur major technology, compliance, customer-service, and cybersecurity costs. Governance should therefore allocate responsibilities clearly and allow sustainable compensation for value-added services while ensuring that basic digital-euro use remains accessible and affordable.

Case Laws

Pringle v Government of Ireland, C-370/12, Court of Justice of the European Union – the Court examined euro-area crisis governance and confirmed the importance of the EU treaty structure in monetary matters. It supports the view that major euro reforms require a valid European legal basis.

Gauweiler v Deutscher Bundestag, C-62/14 – the Court upheld the ECB’s monetary-policy powers subject to limits and proportionality. Digital-euro measures must remain connected to monetary and payment-system objectives.

Weiss v Heinrich Weiss, C-493/17 – the Court confirmed that ECB measures require proportionality review. This is relevant to holding limits, remuneration choices, and design features affecting banks and users.

Rimšēvičs and ECB v Latvia, C-202/18 and C-238/18 – the Court protected the independence of national central-bank governors. It reinforces the need for the Banco de España to act independently within the Eurosystem.

Hessischer Rundfunk, C-422/19 and C-423/19 – the Court considered the legal-tender status of euro cash. The case is important because the digital euro is designed to complement, not improperly displace, access to cash.

Schrems II, C-311/18 – personal data transferred outside the European Economic Area requires effective protection. Any digital-euro technology, cloud, or data-processing arrangement must comply with strict data-governance safeguards.

Conclusion

Digital-euro governance in Spain will be European in authority but national in delivery. The ECB and Eurosystem would control issuance and core design, while the Banco de España, Spanish banks, payment providers, merchants, and public authorities would support implementation. A lawful and trusted digital euro requires central-bank independence, privacy safeguards, financial-stability limits, resilience against cyber risk, universal access, and clear accountability for intermediaries. Its success will depend not only on technical design, but also on whether citizens trust it as secure public money that protects both convenience and fundamental rights.
