1. Meaning of Banking Law in Spain

Banking law regulates the establishment, operation, supervision and, where necessary, restructuring or resolution of banks and other credit institutions.

Its principal objectives are:

1. Financial stability
2. Protection of depositors
3. Protection of customers and investors
4. Maintenance of confidence in the banking system
5. Prevention of excessive systemic risk
6. Protection of payment systems
7. Prevention of taxpayer-funded bank rescues where possible

The Spanish system therefore does not treat a bank simply as an ordinary private company. A bank performs economically essential functions—deposit-taking, lending, payments and credit creation—so its failure can affect the entire economy.

Law 11/2015 expressly identifies continuity of critical functions, financial stability, protection of guaranteed depositors and minimisation of extraordinary public financial support as objectives of resolution.

2. Institutional Framework

A major feature of Spanish banking law is the division of responsibilities between Spanish authorities and EU institutions.

A. Banco de España

The Banco de España is Spain's central bank and performs important supervisory functions, particularly concerning less significant credit institutions under the EU supervisory framework.

It also has an important role in crisis-management and resolution planning.

B. European Central Bank

Under the Single Supervisory Mechanism (SSM), the ECB directly supervises significant banks and exercises important supervisory powers.

The creation of the SSM was one of the central reforms following the European financial crisis.

C. FROB

The Fondo de Reestructuración Ordenada Bancaria (FROB) is Spain's executive resolution authority.

Under Law 11/2015, FROB has a central role in implementing resolution measures in Spain.

D. Single Resolution Board

For banks falling within the SRM, the Single Resolution Board (SRB) is the central European resolution authority.

The importance of the SRB is particularly clear in the Banco Popular case, where the SRB adopted the resolution scheme and FROB implemented it in Spain.

E. Fondo de Garantía de Depósitos

The Spanish Deposit Guarantee Fund (FGD) protects eligible deposits up to the applicable statutory limit, principally €100,000 per depositor per bank.

This is crucial because depositor protection is one of the mechanisms intended to prevent bank runs during periods of crisis.

3. European Banking Union

Spanish banking crisis management cannot be understood exclusively through Spanish legislation.

The EU Banking Union rests principally upon:

1. Single Supervisory Mechanism — SSM

Centralises prudential supervision, particularly for significant banks, under the ECB.

2. Single Resolution Mechanism — SRM

Creates a common European system for resolving failing banks.

3. European Deposit Insurance Framework

The existing system continues to rely on national deposit guarantee schemes, harmonised under EU law, while a fully centralised European Deposit Insurance Scheme has not been completed.

Law 11/2015 itself recognises that Spanish resolution law transposes Directive 2014/59/EU (BRRD) and operates alongside Regulation (EU) No. 806/2014, which establishes the SRM.

4. Bank Crisis Management: The Three Main Stages

The modern Spanish/EU framework can broadly be understood as:

Prevention → Early Intervention → Resolution

Stage 1: Prevention

Banks must maintain sufficient:

• capital;
• liquidity;
• risk-management systems;
• governance;
• internal controls;
• recovery planning;
• resolvability.

The objective is to prevent the institution from reaching a point where failure becomes unavoidable.

Stage 2: Early Intervention

When a bank begins experiencing serious financial difficulties but is not yet at the resolution stage, supervisory authorities can intervene.

The purpose is to restore the bank before its situation becomes irreversible.

Stage 3: Resolution

When the bank is failing or likely to fail, ordinary supervisory measures may no longer be sufficient.

If statutory resolution conditions are satisfied, authorities can place the bank into resolution.

5. What Is Bank Resolution?

Resolution is the controlled restructuring or disposal of a failing bank by a resolution authority.

It differs from an ordinary insolvency proceeding.

Ordinary insolvency generally seeks to liquidate the debtor and distribute its assets to creditors.

Bank resolution instead seeks to preserve the bank's critical functions while imposing losses on shareholders and creditors according to the legal hierarchy.

Law 11/2015 requires resolution authorities to pursue, among other things:

• continuity of critical functions;
• financial stability;
• efficient use of public resources;
• protection of covered depositors;
• protection of customers' assets. 

6. Conditions for Resolution

A bank cannot simply be resolved because its financial position has deteriorated.

The EU/Spanish framework requires important conditions to be satisfied.

Broadly:

1. The bank must be failing or likely to fail

This is commonly abbreviated as FOLF — failing or likely to fail.

2. There must be no reasonable alternative

Private-sector or supervisory measures must not be reasonably capable of preventing failure within the relevant timeframe.

3. Resolution must be in the public interest

Resolution should be necessary to achieve resolution objectives, such as maintaining financial stability and critical functions.

The Banco Popular litigation provides an excellent illustration of these requirements. The EU courts confirmed that the resolution decision was based on the finding that Banco Popular was failing or likely to fail, that alternative measures were insufficient, and that resolution was necessary in the public interest.

7. Major Resolution Tools

The resolution framework provides several important instruments.

A. Sale of Business Tool

The bank, or parts of its business, can be sold to another institution.

This was the instrument used for Banco Popular.

The SRB transferred Banco Popular's shares and capital instruments to Banco Santander on 7 June 2017.

The result was that Banco Popular's banking activities continued rather than undergoing an uncontrolled collapse.

B. Bridge Institution

A resolution authority can transfer critical assets and liabilities to a temporary institution—the bridge bank.

The bridge institution can continue essential banking activities until a permanent solution is found.

C. Asset Separation

Certain assets, particularly problematic or impaired assets, may be transferred to an asset-management vehicle.

The purpose is to separate problematic assets from the institution's critical banking operations.

D. Bail-in

One of the most important post-2008 reforms is bail-in.

Under bail-in, losses are imposed internally on shareholders and certain creditors rather than automatically being absorbed by taxpayers.

The basic hierarchy is broadly:

Shareholders → subordinated creditors → other eligible creditors

subject to statutory exceptions and the applicable creditor hierarchy.

Spanish Law 11/2015 expressly provides that shareholders or members bear losses first and creditors subsequently bear losses according to the applicable priority rules.

8. Bail-out vs Bail-in

This distinction is extremely important in an examination.

Bail-out

A government provides financial assistance using public resources.

Example:

State injects capital into a failing bank.

Bail-in

The bank's shareholders and creditors absorb losses through mechanisms such as write-down or conversion of liabilities.

The post-crisis regulatory philosophy is therefore:

Private losses should generally be borne by investors rather than automatically transferred to taxpayers.

This principle is expressly reflected in the objectives and principles of Spanish resolution law.

9. The Principle of "No Creditor Worse Off"

An important safeguard is the No Creditor Worse Off (NCWO) principle.

A creditor should not ultimately suffer a greater loss in resolution than the creditor would have suffered if the bank had instead entered ordinary insolvency proceedings.

This principle provides a legal limitation on resolution powers.

It is particularly important because resolution authorities possess extraordinary powers that can dramatically affect shareholders and creditors.

10. Banco Popular — The Leading Spanish Banking Resolution Case

6

The Banco Popular resolution is the most important case study in modern Spanish banking crisis management.

Background

Banco Popular was one of Spain's major banks.

Its financial position deteriorated significantly, including:

• substantial provisioning requirements;
• losses;
• market confidence problems;
• severe liquidity deterioration;
• deposit outflows.

In February 2017, Banco Popular disclosed extraordinary provisions of approximately €5.7 billion, resulting in consolidated losses of about €3.485 billion.

By June 2017, its liquidity situation had deteriorated rapidly.

The ECB determined on 6 June 2017 that Banco Popular was failing or likely to fail.

On 7 June 2017, the SRB adopted the resolution scheme.

The business was transferred to Banco Santander for €1.

11. Why Was Banco Popular Resolved?

The SRB concluded that:

1. Banco Popular was failing or likely to fail;
2. there were no reasonable alternative measures capable of preventing failure within the required timeframe; and
3. resolution was necessary in the public interest.

The chosen resolution method was the sale of business tool.

The objective was to preserve the bank's critical functions and avoid significant adverse effects on financial stability, particularly in Spain.

12. Banco Popular Litigation

Shareholders and other interested parties challenged the resolution.

One important case is:

Fundación Tatiana Pérez de Guzmán el Bueno and Stiftung für Forschung und Lehre v Single Resolution Board, Case T-481/17, General Court, 1 June 2022.

The applicants challenged the resolution on grounds including:

• right to property;
• right to be heard;
• duty to give reasons;
• legality of the resolution process;
• valuation;
• proportionality. 

The General Court rejected the action.

The case is particularly important because it illustrates the balance between:

investor rights

and

the public interest in maintaining financial stability.

13. CJEU Case Law on Banco Popular

The litigation did not end with the General Court.

The Court of Justice of the European Union subsequently examined appeals concerning the Banco Popular resolution.

A particularly important principle confirmed by the EU courts is that the causes of a bank's failure do not necessarily prevent resolution where the statutory resolution conditions have been fulfilled.

In other words, the SRB does not necessarily have to establish who was responsible for causing the bank's financial difficulties before exercising resolution powers.

The relevant question under the SRM framework is whether the legal conditions for resolution are satisfied.

This is a significant principle for crisis management because delaying resolution to investigate the ultimate causes of failure could itself increase systemic risk.

14. Banco Popular and the Right to Property

The resolution effectively wiped out the value of existing shareholders and certain capital instruments.

This raises a serious constitutional and EU-law question:

Can public authorities deprive shareholders of their investment without ordinary compensation?

The answer is not simply "yes."

The resolution framework incorporates safeguards, including:

• statutory conditions for resolution;
• proportionality;
• judicial review;
• valuation requirements;
• the NCWO principle;
• protection of fundamental rights.

The General Court's Banco Popular judgments demonstrate that shareholders' property rights must be considered but do not automatically prevent resolution where the statutory requirements and public-interest objectives justify intervention.

15. Case Law: Banco de España / Bankia Crisis

Another essential case-study is the Bankia crisis.

Bankia emerged from the restructuring of Spanish savings banks and subsequently experienced severe financial difficulties.

The wider Spanish banking crisis involved:

• property-market collapse;
• non-performing loans;
• weak savings banks;
• insufficient capital;
• restructuring of cajas;
• substantial public financial assistance.

The Bankia episode ultimately contributed to major reforms in Spanish banking supervision and restructuring.

It is important to distinguish this earlier crisis from Banco Popular.

Bankia

Primarily illustrates:

bank restructuring + recapitalisation + public support

Banco Popular

Primarily illustrates:

EU resolution + bail-in + sale of business + SRM

That distinction is useful in an examination.

16. Spanish Banking Crisis of 2008–2012

The Spanish banking crisis was strongly connected with the collapse of the property boom.

Before the crisis, Spanish banks—particularly savings banks (cajas de ahorros)—had significant exposure to:

• real estate;
• construction;
• property developers.

When property prices declined, banks experienced increasing non-performing loans and losses.

The crisis revealed weaknesses in:

• corporate governance;
• risk management;
• capitalisation;
• supervision;
• transparency.

The response included restructuring and consolidation of financial institutions.

The Spanish legislature subsequently enacted Law 9/2012 on restructuring and resolution of credit institutions, which was later replaced in significant part by Law 11/2015.

Law 11/2015 expressly describes itself as continuing the framework established by Law 9/2012 while implementing the EU BRRD.

17. Evolution of Spanish Crisis Management Law

A useful timeline is:

This represents a fundamental shift from "rescue the bank" toward "manage failure without destabilising the financial system."

18. Role of Recovery Plans

Modern banking regulation does not wait until a bank actually fails.

Banks must prepare for severe financial stress.

A recovery plan identifies measures the bank could take to restore its financial position.

Examples include:

• raising capital;
• selling assets;
• reducing risk;
• restructuring;
• obtaining private funding;
• changing business activities.

The distinction is:

Recovery = action by/within the bank to survive.

Resolution = intervention by the resolution authorities when recovery is no longer a realistic solution.

19. Resolution Planning

Resolution authorities also prepare resolution plans before a crisis occurs.

The plan considers:

• critical functions;
• group structure;
• liabilities;
• capital;
• funding;
• potential resolution tools;
• obstacles to resolution.

Spanish Law 11/2015 requires authorities to assess whether an institution is resolvable and whether resolution can occur without significant adverse effects on the financial system or interruption of critical functions.

This is an important development from the pre-2008 approach.

The regulator essentially asks:

"If this bank fails tomorrow, can we resolve it safely?"

20. Systemic Risk

A fundamental concept in banking crisis management is systemic risk.

A bank can be relatively small in terms of physical assets but still be systemically important because it may be deeply interconnected with:

• payment systems;
• other banks;
• financial markets;
• businesses;
• households;
• government debt markets.

A disorderly bank failure may therefore cause a contagion effect.

This is why resolution law seeks to maintain critical banking functions even where shareholders lose their investment.

Law 11/2015 expressly makes avoiding harmful effects on financial stability one of the objectives of resolution.

21. Deposit Protection

Depositor confidence is fundamental to banking stability.

If depositors believe that their money is unsafe, they may withdraw funds simultaneously.

This can create a bank run, which can transform a liquidity problem into a solvency crisis.

Deposit guarantee systems therefore serve two purposes:

1. protecting individual depositors; and
2. maintaining confidence in the banking system.

Spanish resolution law expressly identifies protection of depositors covered by the Deposit Guarantee Fund as a resolution objective.

22. Relationship Between Liquidity and Solvency

This distinction is essential.

Liquidity crisis

The bank may possess sufficient assets overall but does not have enough immediately available cash to meet withdrawals and payments.

Solvency crisis

The bank's liabilities exceed the value of its assets or its capital position is inadequate.

A liquidity crisis can rapidly become a solvency crisis.

Banco Popular is a useful example because its final deterioration involved an extremely serious liquidity crisis, including substantial deposit outflows and inability to restore liquidity sufficiently.

23. Judicial Review of Resolution Decisions

Resolution authorities have substantial discretion, but they are not immune from judicial review.

Courts can examine:

• whether statutory conditions were satisfied;
• whether procedural requirements were followed;
• whether reasons were provided;
• whether fundamental rights were respected;
• whether the valuation was lawful;
• whether the resolution was proportionate.

However, courts recognise that financial crisis decisions can involve highly technical and economic assessments.

The Banco Popular litigation is therefore particularly significant for defining the appropriate intensity of judicial review.

24. Important Cases to Remember

For an examination or assignment, the following cases are particularly useful:

1. Fundación Tatiana Pérez de Guzmán el Bueno and Stiftung für Forschung und Lehre v SRB, T-481/17, General Court, 1 June 2022

Subject: Banco Popular resolution.

Importance:
Challenges to resolution, property rights, right to be heard, reasoning and SRM powers.

2. Banco Popular appeal litigation before the CJEU

Subject: Legality of Banco Popular's resolution.

Importance:
Confirms the significance of the statutory conditions for resolution and the public-interest nature of the SRM framework.

3. Bankia-related litigation

Subject: Misleading information, investor protection and consequences of the Spanish banking crisis.

Importance:
Demonstrates the interaction between banking regulation, securities law, investor protection and bank restructuring.

25. Key Legal Principles

The whole Spanish crisis-management framework can be reduced to several principles:

Principle 1 — Prevention

Banks should be prevented from reaching failure wherever reasonably possible.

Principle 2 — Early Intervention

Supervisors should act before insolvency becomes unavoidable.

Principle 3 — Resolution Rather Than Disorderly Liquidation

A systemically important bank should be capable of being resolved without destroying critical financial functions.

Principle 4 — Shareholders Bear Losses First

Shareholders are the first loss-absorbers.

Principle 5 — Creditor Hierarchy

Creditors bear losses according to the statutory hierarchy, subject to resolution-law exceptions.

Principle 6 — Minimise Taxpayer Exposure

Resolution should avoid extraordinary public financial support wherever possible.

Principle 7 — Depositor Protection

Covered deposits must be protected.

Principle 8 — Financial Stability

Resolution decisions must consider the broader financial system.

Principle 9 — Fundamental Rights

Resolution powers remain subject to judicial review and EU fundamental rights.

26. Critical Evaluation

The Spanish/EU model represents a major improvement over the crisis-management approach that existed before 2008.

Advantages

First, it reduces the expectation of taxpayer-funded bailouts.

Second, it creates advance resolution planning.

Third, it protects critical banking functions.

Fourth, it provides a European framework for cross-border banks.

Fifth, Banco Popular demonstrated that a large Spanish bank could be resolved over a very short period without a conventional taxpayer-funded bailout.

Problems

However, significant difficulties remain.

1. Valuation disputes

Determining what a failing bank is actually worth is extremely difficult.

2. Speed versus due process

Resolution may need to occur within hours or days, while judicial and administrative procedures normally take much longer.

3. Shareholder protection

The destruction of shareholder value creates difficult questions concerning property rights and compensation.

4. Cross-border complexity

Large banking groups operate across many jurisdictions.

5. Moral hazard

Although bail-in reduces taxpayer exposure, expectations of state or EU intervention may still create moral hazard.

6. Deposit confidence

Even with deposit insurance, rapid withdrawal of uninsured or large deposits can create severe liquidity problems.

27. Exam-Style Conclusion

Spanish banking law has evolved substantially since the financial crisis of 2008. The modern framework combines Spanish legislation with EU Banking Union mechanisms, particularly the SSM and SRM.

The central legislative instrument for crisis management is Law 11/2015, which implements the BRRD and establishes a framework for early intervention and resolution. Its basic philosophy is that banking failure should be managed in a way that protects financial stability and critical functions while placing losses primarily on shareholders and creditors rather than taxpayers.

The Banco Popular resolution of 2017 is the leading practical example. The ECB found that Banco Popular was failing or likely to fail; the SRB concluded that there was no adequate alternative and that resolution was in the public interest; and the bank was ultimately transferred to Santander.

The subsequent Banco Popular litigation, including Fundación Tatiana Pérez de Guzmán el Bueno v SRB, is equally important because it demonstrates how the EU courts balance financial stability and administrative discretion against shareholders' property rights, procedural rights and judicial protection.

Thus, the fundamental transformation of Spanish banking law can be summarised as:

From taxpayer-funded rescue → to preventive supervision → early intervention → orderly resolution → bail-in and protection of critical banking functions.
