Banking Law and Golden Power Rules in the Financial Sector in Spain

Introduction

“Golden power” rules refer broadly to special governmental powers to review, restrict, condition or prohibit investments in strategically important companies or sectors. In Spain, the more precise legal concept is the foreign direct investment (FDI) screening regime, rather than a single statute formally called a “Golden Power Law.”

These rules are important to banking and financial law because acquisitions of significant interests in Spanish banks and other financial institutions may simultaneously involve prudential banking supervision, foreign-investment screening, merger control, securities regulation and corporate law.

The central legal problem is balancing two objectives. Spain and the European Union generally support free movement of capital and investment, but governments may intervene where transactions create genuine risks to security, public order or strategically important infrastructure and activities.

Legal and Regulatory Framework

Spain's foreign-investment framework is principally associated with Law 19/2003 on the legal regime governing movements of capital and economic transactions abroad, as subsequently amended.

Spain substantially strengthened its FDI screening arrangements in 2020. Article 7 bis of Law 19/2003 established authorization requirements for specified foreign direct investments affecting strategically important sectors and circumstances.

The regime has subsequently been developed through implementing legislation, including Royal Decree 571/2023 on foreign investments.

At EU level, Regulation (EU) 2019/452 establishing a framework for the screening of foreign direct investments into the Union provides a cooperation framework between Member States and the European Commission.

The EU Regulation does not create one centralized European authorization authority for every investment. Member States retain their own screening mechanisms while exchanging information and considering relevant security and public-order concerns.

Application to the Financial Sector

Financial institutions can have strategic importance because they perform essential economic functions.

Banks hold deposits, provide credit, process payments, finance businesses and households and participate in financial-market infrastructure. Disruption of a systemically important institution can therefore have consequences beyond ordinary shareholders.

However, foreign-investment screening should be distinguished from banking authorization.

An investor seeking a significant participation in a Spanish credit institution may require assessment under the qualifying-holdings regime established by Spanish and EU banking legislation. Depending on the institution and transaction, Banco de España and the European Central Bank may participate in that prudential process.

Separately, a transaction falling within Spain's foreign-investment screening legislation may require governmental authorization.

Consequently, one acquisition can potentially trigger several parallel regulatory procedures.

Qualifying Holdings in Spanish Banks

Spanish and EU banking legislation carefully regulates acquisitions of significant holdings in credit institutions.

An investor intending to acquire or increase a qualifying holding must comply with applicable notification and assessment requirements.

The prudential authorities may examine matters such as the proposed acquirer's reputation, financial soundness, the future management of the institution, continued compliance with prudential requirements and risks involving money laundering or terrorist financing.

This assessment serves a different purpose from FDI screening.

Prudential supervision focuses primarily on the safety and soundness of the bank, while foreign-investment screening focuses principally on security and public-order considerations.

The same transaction can nevertheless raise both sets of concerns.

Strategic Infrastructure and Financial Technology

Modern banking depends heavily on technological infrastructure.

Payment networks, financial-market infrastructure, cloud services, cybersecurity systems, digital identity platforms and sensitive financial databases may all possess strategic characteristics.

Foreign investment in companies controlling such infrastructure can therefore attract additional regulatory attention.

The analysis is not limited to traditional ownership of physical bank branches. Modern strategic-finance assessments may need to consider control over data, payment technologies, digital infrastructure and critical service providers.

This makes golden-power-style regulation increasingly relevant to financial technology.

Free Movement of Capital

Governmental investment restrictions must also be considered against the EU principle of free movement of capital, principally reflected in Article 63 of the Treaty on the Functioning of the European Union.

The principle can apply to capital movements both within the EU and, subject to treaty qualifications, involving third countries.

Nevertheless, free movement of capital is not absolute.

EU law recognizes circumstances in which restrictions can be justified. Measures based on public security or other recognized interests must satisfy relevant legal requirements, including proportionality.

A government therefore cannot simply describe every economically important company as strategic and impose unrestricted discretionary controls.

Security and Public Order

Spain's FDI screening framework concentrates on risks affecting security, public order and strategically significant sectors or assets.

Financial-sector transactions may attract attention where an investment could provide control or influence over critical financial infrastructure, sensitive information or services important to economic stability.

Authorities can also consider characteristics of the investor where permitted by the applicable legislation.

The assessment is therefore transaction-specific. The nationality of an investor or the existence of foreign ownership does not by itself establish that an investment threatens national security.

Important Case Laws

1. Case C-367/98, Commission v Portugal (2002)

Portugal maintained special governmental rights associated with privatized companies.

The CJEU held that restrictions capable of discouraging investment could interfere with free movement of capital.

The judgment became one of the foundational European “golden shares” cases and demonstrates that governmental control over strategic companies must comply with EU treaty freedoms.

2. Case C-483/99, Commission v France (2002)

The case concerned French governmental powers affecting investments in the petroleum sector.

The CJEU examined whether special state powers restricting investment were compatible with free movement of capital.

The decision demonstrates that public-security considerations can be legally relevant, but restrictions must be appropriately structured and proportionate.

3. Case C-503/99, Commission v Belgium (2002)

Belgium maintained special rights concerning companies operating important energy infrastructure.

Unlike some other golden-share cases, the Court accepted significant aspects of the Belgian arrangements because they were connected with legitimate public-security objectives and were comparatively limited.

The judgment is important because it demonstrates that EU law does not prohibit every special governmental power concerning strategic assets.

4. Joined Cases C-282/04 and C-283/04, Commission v Netherlands (2006)

These proceedings concerned special shares held by the Dutch State in postal and telecommunications companies.

The CJEU concluded that the special rights constituted restrictions on free movement of capital.

For financial-sector screening, the cases reinforce the principle that governmental powers capable of influencing corporate decisions must have adequate justification under EU law.

5. Case C-112/05, Commission v Germany (Volkswagen Law) (2007)

The case concerned provisions granting special influence over Volkswagen, including restrictions affecting voting power and corporate control.

The CJEU found important elements incompatible with free movement of capital.

The case demonstrates that national corporate arrangements cannot artificially discourage investment merely because a government wishes to preserve influence over a strategically significant company.

6. Case C-171/08, Commission v Portugal (Portugal Telecom) (2010)

The Portuguese State possessed special rights in Portugal Telecom through privileged shares.

The Court held that these rights restricted free movement of capital.

The judgment reinforces the requirement that special governmental control mechanisms must satisfy EU-law standards and cannot rely merely upon broad claims of strategic importance.

7. Case C-543/08, Commission v Portugal (Energias de Portugal) (2010)

The case concerned special state rights in the Portuguese energy company EDP.

The CJEU again examined governmental powers capable of influencing corporate governance and foreign investment.

Its significance for Spain lies in the general principle that national measures affecting strategic investments remain subject to EU free-movement requirements.

8. Case C-219/17, Berlusconi and Fininvest v Banca d’Italia and IVASS (2018)

This case is especially important to the banking dimension.

It involved the assessment of a qualifying holding in a credit institution under the European banking-supervision framework and addressed the relationship between national authorities and the ECB.

The judgment demonstrates that acquisitions of significant banking interests can involve composite national-European administrative procedures and EU-level judicial review.

Although it was not an FDI-screening case, it is directly relevant to understanding how ownership changes in regulated banks are scrutinized.

Prudential Screening Versus Golden Power Screening

The distinction between these regulatory systems is essential.

A prudential qualifying-holding assessment asks whether the proposed owner is financially sound, reputable and compatible with safe management of the credit institution.

An FDI screening assessment asks whether the investment threatens security or public order under the applicable foreign-investment legislation.

Merger control asks another question: whether the transaction would significantly harm competition.

Securities legislation can additionally impose disclosure or takeover obligations where listed companies are involved.

Consequently, approval under one regulatory framework does not necessarily eliminate requirements under another.

Government Powers and Procedural Safeguards

Investment-screening powers must operate according to legally defined procedures.

Investors need sufficient clarity concerning which transactions require authorization, what information must be provided and which authority makes the decision.

Administrative decisions must also comply with applicable principles of Spanish and EU administrative law.

These include legality, proportionality and appropriate procedural protection.

Where authorization is conditioned rather than refused, authorities may potentially require measures designed to address identified security concerns, provided that the measures have an adequate legal basis and comply with proportionality requirements.

Banking Groups and Third-Country Investors

The international structure of banking groups can make investment screening particularly complicated.

A proposed acquirer may itself be controlled through several holding companies established in different jurisdictions. Authorities may therefore need to identify the ultimate beneficial ownership and control structure.

Third-country state ownership can also become relevant where legislation permits authorities to consider whether an investor is directly or indirectly controlled by a foreign government.

Nevertheless, regulatory analysis should focus on the statutory criteria and circumstances of the transaction rather than assuming that every foreign government connection creates an unacceptable risk.

AML/CFT Considerations

Acquisitions of significant banking interests also intersect with anti-money-laundering and counter-terrorist-financing regulation.

Authorities assessing a qualifying shareholder may consider whether there are reasonable grounds for concerns relating to money laundering or terrorist financing.

Banks themselves must maintain appropriate customer due diligence, beneficial-ownership identification and transaction-monitoring systems under Spain's Law 10/2010 and the applicable European framework.

These controls complement, but remain legally distinct from, foreign-investment screening.

Financial Stability

Foreign-investment review can also intersect indirectly with financial stability.

Banks perform critical functions and may be highly interconnected with the wider economy. A transaction affecting control of a major institution can therefore have consequences for governance, operational continuity and market confidence.

However, financial-stability concerns should normally be addressed through the banking and resolution frameworks specifically designed for those risks.

Foreign-investment screening should not become a general substitute for ordinary prudential supervision.

This division of responsibilities helps ensure that each regulatory authority acts within its legally defined mandate.

Conclusion

Banking Law and Golden Power Rules in Spain's financial sector involve the interaction between foreign direct investment screening, EU free movement of capital, prudential banking supervision, corporate control, financial stability and national-security considerations.

Spain's framework is principally based on Law 19/2003, including its FDI-screening provisions, together with implementing legislation and the EU framework established by Regulation 2019/452. Banking acquisitions can separately fall within the qualifying-holdings regime administered through Spanish and European banking-supervision mechanisms.

Cases such as Commission v Portugal, Commission v France, Commission v Belgium, Commission v Netherlands, the Volkswagen Law case, Portugal Telecom, Energias de Portugal and Berlusconi and Fininvest demonstrate important principles concerning free movement of capital, strategic state powers, proportionality and regulatory review of bank ownership.

The central principle is that Spain may protect legitimate security and public-order interests in strategically important financial activities, but intervention must operate within clearly defined legal powers, appropriate procedures, EU internal-market requirements and proportionality safeguards.
