1. Structure of Spanish Banking Law

The Spanish banking-law framework operates at three principal levels:

A. European Union law

The most important EU instruments include:

• Capital Requirements Regulation (CRR) — Regulation (EU) 575/2013
• Capital Requirements Directive (CRD)
• Bank Recovery and Resolution Directive (BRRD) — Directive 2014/59/EU
• Single Supervisory Mechanism (SSM) — Regulation (EU) 1024/2013
• Single Resolution Mechanism (SRM) — Regulation (EU) 806/2014
• Deposit Guarantee Scheme Directive
• EU rules concerning consumer protection, payment services and mortgage lending.

The Banking Union is particularly important because major Spanish banks are supervised within the European Central Bank (ECB) framework, while resolution of significant banks is generally handled through the Single Resolution Board (SRB).

B. Spanish legislation

Important Spanish statutes include:

1. Law 10/2014 on the organisation, supervision and solvency of credit institutions.
2. Law 11/2015 on recovery and resolution.
3. Law 26/2013 concerning savings banks and banking foundations.
4. Legislation governing the FROB.
5. Legislation concerning the Deposit Guarantee Fund (FGD).
6. Spanish contractual, consumer, insolvency and company law.

The Banco de España itself identifies Law 10/2014, Law 11/2015 and Royal Decree 1012/2015 as central elements of the Spanish recovery and resolution framework.

2. Main Banking Authorities in Spain

A good examination answer should distinguish between supervision, resolution, and deposit protection.

Law 11/2015 assigns preventive resolution functions to the Banco de España for credit institutions and to the CNMV for investment firms, while the FROB is the executive resolution authority under Spanish law.

For banks falling within the EU Single Resolution Mechanism, the FROB participates as the Spanish resolution authority in the SRM, while the SRB has the central resolution role.

3. Why Banking Crisis Management Is Different from Ordinary Insolvency

This is one of the most important concepts.

Ordinary companies can generally be dealt with through insolvency proceedings. A bank is different because its failure can cause:

• loss of public confidence;
• bank runs;
• interruption of payment systems;
• loss of deposits;
• contagion to other financial institutions;
• disruption of credit to businesses and households;
• systemic financial instability.

Law 11/2015 expressly recognises that ordinary judicial insolvency may be inadequate for complex financial institutions because of their size, interconnectedness and the importance of deposits and payment systems.

Therefore, Spain uses a special administrative resolution regime.

Key distinction

Ordinary insolvency

Preserve creditor interests through judicial insolvency proceedings.

Bank resolution

Restructure or wind down a failing bank in a way that preserves critical functions and financial stability.

That distinction is fundamental to Spanish crisis-management law.

4. Evolution of Spanish Banking Crisis Management

The modern framework cannot be understood without the Spanish financial crisis of 2008–2012.

The crisis particularly affected the Spanish cajas de ahorros and institutions exposed to the real-estate sector.

The legal response evolved approximately as follows:

First stage — traditional supervision and intervention

Authorities attempted to deal with failing institutions through mergers, restructuring and public assistance.

Second stage — FROB

The Fund for Orderly Bank Restructuring (FROB) became the central instrument for restructuring troubled banks.

Third stage — Law 9/2012

Law 9/2012 introduced a more sophisticated framework for restructuring and resolution.

Fourth stage — Law 11/2015

Law 11/2015 implemented the BRRD framework and established a modern recovery and resolution system.

The 2013 legislation expressly refers to the historic scale of Spain's financial-sector restructuring and the need to balance financial stability with efficient use of public resources.

5. Recovery vs Resolution

This distinction is extremely important.

Recovery

Recovery takes place before the bank has failed.

A bank prepares a recovery plan explaining how it would restore financial viability if its financial position deteriorated.

Examples include:

• raising new capital;
• selling assets;
• reducing risk;
• restructuring liabilities;
• obtaining private-sector financing;
• disposing of business units.

The basic assumption is:

The bank itself may still be capable of recovery.

Resolution

Resolution occurs when recovery is no longer realistically sufficient.

Under the Spanish framework, resolution is associated with three essential ideas:

1. The institution is failing or likely to fail;
2. there is no reasonable prospect that private-sector measures will restore viability;
3. resolution is necessary in the public interest rather than ordinary insolvency.

Law 11/2015 defines resolution around precisely these concepts.

6. Early Intervention

Between ordinary supervision and resolution lies early intervention.

This is designed to prevent a bank's deterioration from becoming irreversible.

The authorities can intervene where the bank is breaching, or is likely to breach, prudential requirements but still has a realistic possibility of returning to compliance.

Measures may include:

• requiring implementation of a recovery plan;
• requiring changes in management;
• requiring shareholders or management to take corrective measures;
• requiring restructuring;
• imposing restrictions on business activity.

Thus the system can be represented as:

Ordinary supervision → Early intervention → Resolution

with the aim of intervening before complete collapse.

7. Resolution Objectives

Article 3 of Law 11/2015 identifies several objectives.

The principal objectives include:

1. Continuity of critical functions

Essential financial services should continue operating.

Examples:

• payment services;
• deposits;
• clearing and settlement;
• essential lending functions.

2. Financial stability

Authorities should prevent contagion from one institution to the wider banking system.

3. Protection of public funds

The framework attempts to minimise extraordinary public financial support.

4. Protection of depositors

Covered depositors receive particular protection.

The statute expressly places continuity of essential activities, financial stability and efficient use of public resources among the resolution objectives.

8. The "No Bailout" Principle and Bail-In

One of the biggest changes following the financial crisis was the move away from the idea that taxpayers should automatically rescue failing banks.

The modern system follows the principle:

Shareholders and creditors should absorb losses before public money is used.

This is known as bail-in or internal recapitalisation.

It means that certain liabilities of a failing bank can be:

• written down; or
• converted into equity.

The hierarchy generally starts with shareholders and then moves through eligible creditor classes according to the applicable ranking.

This is very different from a traditional bailout.

Bailout

Government provides money to keep the bank alive.

Bail-in

The bank's own shareholders and eligible creditors bear losses.

Law 11/2015 was expressly designed to minimise the impact on taxpayers and make investors, rather than citizens through taxation, absorb the losses associated with resolution.

9. Resolution Tools under Spanish Law

Law 11/2015 provides several important resolution tools.

A. Sale of business

The authorities can transfer the bank, or part of its business, to a private purchaser.

This was crucial in the Banco Popular resolution.

B. Bridge institution

A temporary institution can be established to receive viable assets and activities.

The purpose is to maintain critical functions while the authorities determine the final solution.

C. Asset separation

Problematic assets can be transferred to an asset-management vehicle.

This prevents bad assets from destroying the viable part of the bank.

D. Bail-in

Capital instruments and eligible liabilities can be written down or converted into equity.

The Spanish framework expressly identifies sale of business, bridge institution and asset separation as resolution instruments, with bail-in regulated separately because of its special characteristics.

10. The Banco Popular Crisis — The Most Important Spanish Case

If you are studying Banking Law and Crisis Management in Spain, Banco Popular is probably the single most important case study.

5

Background

Banco Popular Español was one of Spain's major banks.

In June 2017, its financial position deteriorated rapidly, particularly because of liquidity problems.

The ECB determined that Banco Popular was failing or likely to fail.

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

The resolution involved:

• write-down/conversion of capital instruments;
• transfer of the resulting shares;
• sale of the business to Banco Santander;
• transfer price of approximately €1.

The General Court's official summary confirms these essential facts.

11. Banco Popular Litigation

The Popular resolution produced extensive litigation by shareholders and investors.

Among the principal cases was:

Del Valle Ruiz and Others v Commission and SRB

Case T-510/17

The applicants challenged the legality of the resolution.

They raised issues including:

• right to be heard;
• right to property;
• adequacy of reasoning;
• delegation of powers;
• valuation of the bank;
• legality of the resolution procedure.

The General Court rejected the action in its 1 June 2022 judgment.

Other related cases included:

• T-481/17
• T-523/17
• T-570/17
• T-628/17

The General Court dismissed the principal challenges to the Popular resolution.

12. Why the Banco Popular Case Is Legally Important

Banco Popular demonstrates the tension between:

Financial stability

and

Individual property rights.

Shareholders argued, in substance, that they had lost their investment through an administrative resolution procedure.

The EU courts had to balance this against:

• financial stability;
• urgency;
• confidentiality;
• prevention of a bank run;
• the need for rapid intervention;
• the statutory resolution objectives.

This demonstrates a fundamental principle of crisis management:

Bank resolution requires administrative authorities to make extremely consequential decisions very quickly, while remaining subject to judicial review.

13. The Right to Be Heard

One major legal issue in Popular litigation was the right to be heard.

Normally, administrative law strongly protects the right of affected persons to make representations before an adverse decision.

But bank resolution creates a special problem.

Suppose authorities publicly announce:

"We are considering resolving Banco X."

If the information is disclosed prematurely, depositors and counterparties may panic and withdraw funds.

That could cause the very bank failure that the authorities are attempting to prevent.

Therefore, the resolution framework allows substantial restrictions on ordinary procedural requirements where necessary to preserve confidentiality and effectiveness.

This is one reason why the Popular litigation is so important for understanding the relationship between:

administrative due process + financial stability.

14. Protection of Property Rights

The right to property is another major issue.

Resolution may result in shareholders losing virtually all of their investment.

This raises questions under:

• Article 17 of the EU Charter of Fundamental Rights;
• constitutional property protections;
• general principles of EU law;
• proportionality.

The key principle is that shareholders do not possess an absolute right to prevent resolution.

If a bank is genuinely failing, shareholders cannot necessarily insist that the state preserve their investment at the expense of financial stability.

However, resolution authorities must still comply with the applicable legal safeguards and valuation requirements.

15. "No Creditor Worse Off" Principle

A major safeguard is the No Creditor Worse Off (NCWO) principle.

The basic idea is:

A shareholder or creditor should not ultimately be worse off through resolution than that person would have been in ordinary insolvency.

This requires a counterfactual valuation.

Authorities therefore compare:

Actual outcome under resolution

with

Hypothetical outcome under ordinary insolvency.

If the creditor would have received more in insolvency than under resolution, compensation mechanisms may become relevant.

This principle is extremely important because it provides a legal counterweight to the extraordinary powers given to resolution authorities.

16. Banco Popular and Investor Claims

The Popular crisis also generated litigation by investors who had purchased shares before the resolution.

An especially important later development concerns the interaction between:

• investor-protection claims;
• prospectus liability;
• national contract law;
• the EU resolution framework.

The Spanish Supreme Court has subsequently applied the EU jurisprudence concerning the consequences of the extinguishment of Banco Popular shares.

For example, a 2025 Supreme Court judgment concerning an investor's claim against Banco Santander reiterated the significance of the CJEU's interpretation that, after total write-down of Banco Popular's shares in resolution, certain claims seeking rescission or restitution cannot simply operate in a way that reverses the resolution.

This is an important lesson:

Resolution law can take priority over ordinary private-law remedies where those remedies would undermine the legal consequences of a completed bank resolution.

17. CJEU and Banco Popular

The Popular litigation has also reached the Court of Justice of the European Union.

An important later issue was whether former shareholders could pursue national-law claims that effectively restored the value of shares already extinguished in resolution.

The CJEU's interpretation of the BRRD framework has significant implications for the relationship between:

EU resolution law

and

national investor-protection/private-law remedies.

For examination purposes, the principle to remember is:

Once a bank has been legally resolved and its capital instruments have been extinguished, national remedies cannot simply undo the resolution by restoring those instruments or their economic value contrary to the EU resolution framework.

18. Mortgage Banking Law: Gómez del Moral Guasch v Bankia

Banking law in Spain is not only about failing banks.

Consumer protection is another major component.

A leading case is:

Gómez del Moral Guasch v Bankia SA

C-125/18, CJEU, Grand Chamber, 3 March 2020

The case concerned a Spanish mortgage whose variable interest rate was linked to the IRPH reference index.

The CJEU held that the contractual term could fall within the scope of the EU Unfair Terms Directive and that Spanish courts must examine whether the term was expressed in a sufficiently clear and intelligible way.

This is significant because it demonstrates the role of EU consumer law in Spanish banking contracts.

19. Why Gómez del Moral Guasch Matters

The case demonstrates three important principles.

First — Banking contracts are not immune from consumer law

Banks are sophisticated financial institutions, but consumers continue to receive protection under EU consumer legislation.

Second — Transparency goes beyond grammatical clarity

A clause may be linguistically understandable but still fail the required transparency standard if the consumer cannot properly understand its economic consequences.

Third — Courts may intervene in the consequences of an unfair term

The CJEU explained that, under certain circumstances, a national court can replace an unfair contractual term with a supplementary provision of national law where eliminating the term entirely would expose the consumer to particularly unfavourable consequences.

20. Spanish Supreme Court Case Law and Banking Transparency

The Spanish Supreme Court has developed substantial jurisprudence concerning:

• mortgage clauses;
• floor clauses;
• transparency;
• unfair terms;
• banking products;
• investment products;
• information duties.

For example, STS 643/2017 of 24 November 2017 concerned contractual transparency and an action involving Banco Popular.

The broader lesson from Spanish banking jurisprudence is that courts increasingly examine not merely whether a bank formally complied with disclosure requirements, but whether the customer actually received information sufficient to understand the legal and economic consequences of the product.

21. Crisis Management and SAREB

An important feature of Spain's post-crisis restructuring was the creation of SAREB — Sociedad de Gestión de Activos Procedentes de la Reestructuración Bancaria.

SAREB was established to deal with problematic assets arising from bank restructuring, particularly real-estate-related assets.

The 2013 crisis legislation expanded the ability of the Deposit Guarantee Fund to participate in SAREB-related transactions and acquire certain instruments from restructured institutions.

The basic crisis-management logic was:

Bad assets → remove them from troubled banks → isolate/manage them → allow viable banking operations to continue.

This is an example of asset separation, one of the concepts that later became formalised within the European resolution architecture.

22. Deposit Guarantee

Another critical crisis-management mechanism is deposit protection.

The objective is to prevent ordinary depositors from reacting to banking distress by immediately withdrawing all their money.

Deposit protection therefore serves two functions:

Individual protection

The depositor receives protection up to the applicable guaranteed amount.

Systemic protection

Deposit insurance reduces the incentive for mass withdrawals and therefore reduces the risk of bank runs.

The Banco de España identifies protection of covered depositors as one of the objectives of the resolution framework.

23. Confidentiality in Crisis Management

Bank crisis management depends heavily upon confidentiality.

Consider the following:

If regulators publicly announce that a bank is experiencing severe liquidity problems, customers may immediately withdraw deposits.

This creates a self-fulfilling crisis.

Therefore:

Information disclosure in ordinary administrative law

may conflict with

confidentiality in bank resolution.

Resolution legislation therefore gives authorities significant powers to protect sensitive information.

This does not mean authorities are immune from judicial review. Rather, judicial review occurs within a framework that recognises the extraordinary urgency and confidentiality of financial resolution.

24. Administrative Law Dimension

Bank resolution is also an important branch of financial administrative law.

The authorities exercise public powers affecting:

• shareholders;
• creditors;
• directors;
• depositors;
• purchasers;
• financial markets.

Therefore, principles such as:

Legality

Authorities must act within statutory powers.

Proportionality

Measures must be appropriate and necessary.

Equality

Comparable parties should not be treated arbitrarily differently.

Due process

Affected persons must receive appropriate procedural protection, subject to crisis-specific limitations.

Judicial review

Administrative decisions remain reviewable.

The Popular litigation demonstrates how these principles operate in practice.

25. Judicial Review of Resolution Decisions

Judicial review in financial crisis cases is unusual because courts must examine decisions based on highly technical financial information.

Courts may have to consider:

• bank liquidity;
• capital requirements;
• asset valuations;
• market conditions;
• supervisory assessments;
• alternative resolution strategies.

Consequently, courts generally recognise a degree of institutional discretion for specialist authorities, while still reviewing:

• manifest errors;
• procedural violations;
• proportionality;
• reasoning;
• legal competence;
• fundamental rights.

This produces a delicate balance between technical regulatory expertise and judicial protection of rights.

26. Resolution Planning

Modern crisis management does not wait until a bank fails.

Banks are required to be resolvable.

Resolution authorities prepare resolution plans identifying:

• critical functions;
• legal structures;
• liabilities;
• barriers to resolution;
• possible resolution strategies;
• valuation issues;
• funding requirements.

Law 11/2015 provides for resolution planning and gives authorities powers to address obstacles to resolvability.

This is a major conceptual change from the pre-2008 system.

Old approach

"What do we do if this bank fails?"

Modern approach

"How do we design this bank so that it can be resolved safely if it fails?"

27. The Banking Union Dimension

Spanish banking crisis management cannot be studied entirely through Spanish law.

For significant Spanish banks, the structure is approximately:

ECB → supervision

SRB → resolution

FROB → Spanish resolution authority/national participant

Banco de España → national supervisory and preventive-resolution functions

This creates a form of shared European financial administration.

The Banco de España confirms that the Spanish framework transposes the BRRD and operates alongside the Single Resolution Mechanism.

28. Key Case Law — Examination Table

The five main Popular actions were all dismissed by the General Court in June 2022.

29. Major Legal Principles to Remember

For an examination, the following principles are particularly important.

Principle 1 — Financial stability

The stability of the financial system is a legitimate and central public objective.

Principle 2 — Early intervention

Authorities should intervene before a bank becomes irretrievably insolvent.

Principle 3 — Resolution rather than ordinary liquidation

Systemically important banks require special procedures.

Principle 4 — Bail-in

Shareholders and eligible creditors should absorb losses before taxpayers.

Principle 5 — Critical functions

Resolution should preserve essential banking services.

Principle 6 — No creditor worse off

Resolution should not leave creditors worse off than hypothetical ordinary insolvency.

Principle 7 — Proportionality

Resolution powers must be exercised within the legal framework and fundamental-rights constraints.

Principle 8 — Confidentiality

Rapid intervention may justify restrictions on ordinary disclosure and hearing procedures.

Principle 9 — Judicial review

Even powerful resolution authorities remain subject to legal review.

Principle 10 — EU supremacy/integration

Spanish banking crisis management is deeply integrated with EU law and the Banking Union.

30. A Simple Crisis-Management Model

You can remember Spanish bank crisis management as:

1. Supervision

↓

2. Recovery planning

↓

3. Early intervention

↓

4. Failing or likely to fail

↓

5. Public-interest test

↓

6. Resolution

↓

7. Bail-in / sale / bridge bank / asset separation

↓

8. Judicial review + NCWO protection

This is the basic architecture of modern Spanish banking crisis management.

31. Critical Evaluation

The Spanish system has several advantages.

Advantages

First, it reduces dependence on taxpayer-funded bailouts.

Second, it attempts to prevent systemic contagion.

Third, resolution planning makes crisis management more predictable.

Fourth, bail-in improves market discipline.

Fifth, deposit protection protects ordinary customers.

Sixth, EU-level supervision and resolution can be more effective for cross-border banks.

Problems and criticisms

There are also serious difficulties.

1. Valuation

Determining the true value of a failing bank within hours or days is extremely difficult.

2. Shareholder protection

Resolution can destroy shareholder value very quickly.

3. Procedural fairness

It is difficult to give affected investors a meaningful hearing while simultaneously preserving confidentiality.

4. Democratic accountability

Large administrative bodies can make decisions involving billions of euros without the ordinary speed and visibility of parliamentary or judicial processes.

5. Moral hazard

Although bail-in reduces taxpayer exposure, markets may still assume that very large banks will receive exceptional support.

6. Complexity

The coexistence of Spanish law, EU law, ECB supervision, SRB resolution, FROB powers and national courts creates significant legal complexity.

32. Overall Conclusion

Spanish banking law has undergone a fundamental transformation since the financial crisis.

The old model was largely:

supervision → crisis → public restructuring/bailout

The modern model is:

prudential supervision → recovery planning → early intervention → resolution planning → resolution/bail-in

The central statute is Law 11/2015, operating together with the EU BRRD and the Single Resolution Mechanism. It gives authorities exceptional powers because the failure of a bank can threaten the entire financial system.

The Banco Popular resolution is the most important practical illustration. The General Court's 2022 judgments demonstrate that the EU courts generally upheld the legality of the resolution despite extensive challenges concerning property rights, procedural safeguards, valuation and institutional powers.

At the same time, cases such as Gómez del Moral Guasch v Bankia show that crisis management is only one part of Spanish banking law: banks remain subject to strong obligations concerning consumer protection, contractual transparency and fundamental rights.

In short: Spanish banking law seeks to reconcile four potentially conflicting objectives:

financial stability + depositor protection + investor/creditor rights + minimisation of taxpayer losses.

That balancing exercise is the central theme of Spanish banking crisis-management law.
