Banking Law and Rehabilitation Procedures in Spain

1. Introduction

In Spanish banking law, rehabilitation procedures can be understood as the legal and supervisory mechanisms used to restore the viability of a bank experiencing serious financial or operational difficulties before, where possible, it reaches ordinary insolvency or full resolution.

Spanish legislation does not generally organize this field under a single procedure formally named “bank rehabilitation.” Instead, rehabilitation is achieved through a combination of:

• prudential supervision and supervisory intervention;
• recovery planning;
• early-intervention measures;
• restructuring and recapitalisation;
• resolution planning;
• resolution measures where recovery is no longer realistic;
• insolvency proceedings in cases falling outside, or following, the special bank-resolution framework.

The system is heavily influenced by EU law, particularly the Bank Recovery and Resolution Directive (BRRD) and the Single Resolution Mechanism Regulation (SRMR).

Important Spanish legislation includes Law 10/2014 on the organisation, supervision and solvency of credit institutions and Law 11/2015 on the recovery and resolution of credit institutions and investment firms.

2. Purpose of Bank Rehabilitation

Ordinary corporate insolvency focuses substantially on creditors and the debtor's estate. Bank distress creates additional public-interest concerns.

A failing bank may affect:

Bank → depositors → payment system → other banks → credit markets → businesses and households → wider economy.

Consequently, rehabilitation procedures seek to achieve several objectives simultaneously:

• restore viability where possible;
• protect critical banking functions;
• reduce systemic contagion;
• protect covered depositors;
• preserve financial stability;
• minimise unnecessary public financial support;
• allocate losses according to the applicable legal hierarchy.

The objective is not to preserve every troubled bank at any cost.

3. Institutional Framework

Spanish bank rehabilitation operates within the European Banking Union.

Important authorities include:

Banco de España

It exercises important supervisory functions within the Single Supervisory Mechanism and participates in early intervention and prudential oversight.

European Central Bank

For institutions within its supervisory competence, the ECB exercises significant prudential supervisory powers.

FROB

Spain's Fund for Orderly Bank Restructuring (FROB) performs important functions within the resolution framework.

Single Resolution Board

The SRB is the central resolution authority for institutions and banking groups falling within its responsibilities under the Single Resolution Mechanism.

The framework therefore involves both national and EU institutions.

4. Stage One — Normal Prudential Supervision

Bank rehabilitation ideally begins long before insolvency.

Banks must satisfy requirements concerning:

• regulatory capital;
• liquidity;
• governance;
• internal controls;
• risk management;
• large exposures;
• reporting;
• operational resilience.

Supervisors continuously assess whether deterioration is emerging.

Indicators may include:

• falling capital ratios;
• liquidity shortages;
• rapidly increasing non-performing loans;
• governance failures;
• operational disruptions;
• loss of market confidence.

Early detection increases the possibility of private recovery.

5. Recovery Plans

Banks are required within the applicable BRRD framework to prepare recovery plans.

A recovery plan identifies measures that could restore the institution's financial position following severe deterioration.

Possible measures include:

• raising capital;
• selling assets;
• reducing risk-weighted assets;
• disposing of business units;
• obtaining additional funding;
• reducing costs;
• changing business strategy;
• improving liquidity.

A recovery plan should contain realistic options rather than simply assuming government rescue.

6. Recovery Indicators

Banks need indicators that identify when recovery measures may need to be considered.

Examples include:

The purpose is to trigger action before the bank becomes irreversibly non-viable.

7. Early Intervention

Where a bank deteriorates materially, supervisors can move beyond ordinary supervision.

Early-intervention measures under the European framework may involve requiring the institution to:

• implement elements of its recovery plan;
• examine changes to its strategy;
• change aspects of governance;
• prepare restructuring measures;
• negotiate arrangements concerning liabilities;
• provide additional information.

The legal objective is:

Intervene early enough that private recovery remains possible.

This stage is important because resolution should generally not be the first response to every prudential weakness.

8. Private-Sector Rehabilitation

A distressed Spanish bank can sometimes be restored without formal resolution.

Possible measures include:

Capital raising

Existing or new investors inject capital.

Asset sales

Non-core assets are sold to improve liquidity and capital.

Liability restructuring

Financial liabilities may be restructured subject to applicable law.

Merger or acquisition

A stronger institution acquires or combines with the troubled bank.

Business restructuring

Loss-making activities are discontinued.

Management changes

Governance deficiencies are corrected.

Private rehabilitation is generally preferable where it can restore viability without threatening financial stability or violating regulatory requirements.

9. When Rehabilitation Becomes Resolution

The resolution framework becomes relevant where the statutory conditions for resolution are satisfied.

A central concept is whether the bank is:

failing or likely to fail (FOLTF).

Resolution additionally depends on the other applicable statutory conditions, including the absence of a reasonable alternative private-sector or supervisory measure within an appropriate timeframe and the existence of a public interest in resolution.

This distinction is crucial.

A failing bank does not automatically have to be rescued through resolution.

10. Resolution Versus Ordinary Insolvency

Authorities assess whether resolution is necessary in the public interest.

Relevant considerations include:

• continuity of critical functions;
• financial stability;
• protection of public funds;
• protection of covered deposits;
• protection of client funds and assets.

If resolution is not justified in the public interest, the institution may instead enter the applicable ordinary insolvency or winding-up framework.

11. Resolution Tools

Spanish and EU banking law provide several major resolution mechanisms.

Sale of Business

All or part of the institution can be transferred to a purchaser.

Bridge Institution

Critical functions may temporarily be transferred to a controlled bridge entity.

Asset Separation

Certain assets can be transferred to an asset-management vehicle under the statutory conditions.

Bail-in

Eligible liabilities may be written down or converted into equity according to the statutory framework.

These mechanisms allow authorities to restructure the institution while protecting critical financial functions.

12. Bail-In and Creditor Hierarchy

Bail-in represented an important change from traditional taxpayer-funded bank rescues.

In simplified terms, losses are generally imposed according to the applicable hierarchy, beginning with equity and then moving through relevant subordinated and eligible liabilities.

However, the precise treatment depends on the legal classification of each instrument, exclusions from bail-in and the applicable insolvency hierarchy.

A major safeguard is the principle known as:

No Creditor Worse Off (NCWO).

Resolution should not leave a creditor worse off than that creditor would have been under the relevant counterfactual normal insolvency proceeding, subject to the statutory valuation mechanism.

13. Banco Popular — Central Spanish Example

Banco Popular Español Resolution, 2017

Banco Popular experienced a severe liquidity crisis. On 6 June 2017, the ECB determined that the institution was failing or likely to fail.

The SRB adopted a resolution scheme. FROB implemented the resolution, and Banco Popular was transferred to Banco Santander for €1 after relevant capital instruments had been written down or converted.

This became one of the most important cases under the Single Resolution Mechanism.

Importance

The case demonstrates that bank rehabilitation has limits.

When deterioration becomes sufficiently severe and the statutory resolution conditions are satisfied, authorities can move rapidly from supervisory management of distress to formal resolution.

14. Case Law 1 — Aeris Invest v Commission and SRB

General Court, T-628/17

Aeris Invest challenged measures connected with Banco Popular's resolution.

The General Court rejected the action.

The litigation addressed significant questions concerning:

• resolution powers;
• property rights;
• proportionality;
• valuation;
• procedural safeguards;
• rights of shareholders.

Rehabilitation significance

Shareholder interests are relevant, but the resolution framework permits substantial interference with those interests where statutory resolution requirements are satisfied.

15. Case Law 2 — Algebris and Anchorage v Commission

General Court, T-570/17

Investors challenged the Banco Popular resolution framework.

The case formed part of the extensive litigation arising from the resolution.

Importance

The litigation demonstrates the difficult balance between:

investor protection ↔ rapid resolution ↔ financial stability.

Resolution decisions may need to be made extremely quickly because bank liquidity crises can accelerate within hours or days.

16. Case Law 3 — Fundación Tatiana Pérez de Guzmán el Bueno and SFL v SRB

General Court, T-481/17

This was another important action concerning Banco Popular's resolution.

The litigation addressed questions surrounding the legality of the resolution process and protection of affected investors.

Significance

Resolution authorities need a legally defensible evidential and procedural basis even when acting during severe financial distress.

Emergency conditions do not completely remove judicial scrutiny.

17. Case Law 4 — Del Valle Ruíz and Others v Commission and SRB

General Court, T-510/17

Former shareholders and creditors challenged aspects of the Banco Popular resolution.

The case formed part of the General Court's major 2022 Banco Popular judgments.

Significance

The litigation illustrates how bank-resolution decisions can affect:

• shareholders;
• subordinated creditors;
• property interests;
• procedural rights.

The public-interest objective of financial stability must operate within a legally defined resolution framework.

18. Case Law 5 — ABLV Bank v ECB

CJEU, Joined Cases C-551/19 P and C-552/19 P

Although involving Latvian institutions rather than a Spanish bank, this case is highly relevant to Spain because Spain participates in the same Banking Union framework.

The litigation concerned the legal character and reviewability of the ECB's failing-or-likely-to-fail assessment in the resolution architecture.

Spanish relevance

It helps explain the institutional division between:

ECB supervisory assessment → resolution authority's statutory decision-making.

Understanding that division is essential when analysing Spanish bank rehabilitation and resolution.

19. Case Law 6 — Kotnik and Others

CJEU, C-526/14

This case concerned state aid for banks and burden-sharing measures.

The Court considered requirements affecting shareholders and subordinated creditors before state support.

Importance for rehabilitation

Public recapitalisation is constrained by EU state-aid law.

Authorities cannot simply inject public money into an insolvent or distressed institution without considering:

• EU state-aid rules;
• burden sharing;
• restructuring;
• competition;
• financial-stability requirements.

20. Case Law 7 — Dowling and Others

CJEU, C-41/15

The case arose from the restructuring of an Irish bank during the financial crisis.

The Court considered emergency recapitalisation measures and EU company-law requirements.

Spanish relevance

The judgment illustrates how extraordinary financial-stability measures can interact with ordinary corporate-law protections.

During serious banking distress, rehabilitation may require measures that would be unusual in normal corporate governance.

21. Case Law 8 — Ledra Advertising

CJEU, Joined Cases C-8/15 P to C-10/15 P

The cases concerned measures connected with the Cyprus banking crisis.

The Court examined EU institutional responsibility and fundamental rights, including property rights.

Rehabilitation significance

Bank restructuring must consider fundamental rights even where severe financial-stability concerns exist.

Crisis management does not create a completely law-free zone.

22. State Aid and Rehabilitation

Government assistance to distressed banks creates a separate layer of EU law.

Possible assistance might include:

• recapitalisation;
• guarantees;
• asset-relief measures;
• liquidity support.

But such assistance may constitute State aid under Article 107 TFEU.

Authorities must therefore consider:

Bank rehabilitation + BRRD/SRMR + EU State-aid rules.

This prevents Member States from freely subsidising domestic banks in ways that distort competition.

23. Depositor Protection

One important objective of the rehabilitation and resolution framework is depositor confidence.

Covered deposits are protected through the deposit-guarantee framework up to the legally applicable limit, generally €100,000 per depositor per credit institution under the harmonised EU framework.

Depositor protection is important because widespread fear of losses can trigger bank runs and accelerate liquidity failure.

24. Ordinary Insolvency as the Counterfactual

Ordinary insolvency remains important even when a bank is resolved.

For example, the NCWO principle requires comparison with the treatment creditors would have received under the relevant normal insolvency counterfactual.

This means insolvency law remains an important benchmark for evaluating resolution outcomes.

25. Judicial Protection

Affected parties may challenge aspects of resolution decisions before the appropriate EU or Spanish courts, depending on which authority adopted the contested act.

This creates a complex system:

ECB decision → EU judicial review

SRB decision → EU judicial review

FROB national implementation measures → Spanish judicial procedures where applicable

The precise route depends on the legal act being challenged.

26. Rehabilitation Procedure in Simplified Form

A distressed Spanish bank can therefore move through the following sequence:

Normal supervision

↓

Financial deterioration detected

↓

Recovery plan activated

↓

Supervisory / early intervention

↓

Private recapitalisation, restructuring, asset sale or merger

↓

Assessment of whether the bank is failing or likely to fail

↓

Assessment of alternative measures

↓

Public-interest assessment

↓

Resolution if statutory conditions are satisfied

or

Normal insolvency/winding-up where resolution is not justified

↓

Restructuring, transfer, bail-in or liquidation

This is better understood as a continuum of crisis-management measures rather than one single rehabilitation proceeding.

27. Major Cases at a Glance

Not all of these cases arose in Spain. The non-Spanish cases remain relevant because they interpret EU rules and principles forming part of the legal framework governing Spanish banks.

28. Key Legal Challenges

Speed versus due process

Bank crises can develop extremely quickly, while affected investors are entitled to legal safeguards.

Valuation uncertainty

Authorities may need to value a deteriorating bank under severe time pressure.

Private rights versus systemic stability

Shareholders and creditors have legal rights, but banking failure may threaten broader financial stability.

National versus EU authority

Spain's crisis-management system is divided among the Banco de España, FROB, ECB and SRB.

Bail-in versus public rescue

Modern EU law seeks to limit automatic reliance on taxpayer-funded bailouts.

Recovery versus resolution

Authorities must determine when rehabilitation remains credible and when resolution or insolvency has become necessary.

Conclusion

Bank rehabilitation procedures in Spain form a multi-stage system of prevention, recovery, early intervention, restructuring, resolution and, where appropriate, insolvency. The principal domestic statutes include Law 10/2014 and Law 11/2015, operating within the EU framework established by the BRRD and Single Resolution Mechanism.

The system begins with recovery planning and supervisory intervention rather than waiting for formal insolvency. If private or supervisory measures cannot restore viability and the statutory conditions are satisfied, authorities can employ resolution tools such as sale of business, bridge institutions, asset separation and bail-in.

The Banco Popular resolution and the resulting Aeris Invest, Algebris/Anchorage, Fundación Tatiana and Del Valle Ruíz litigation provide especially important Spanish examples. ABLV Bank, Kotnik, Dowling and Ledra Advertising add broader EU principles concerning resolution architecture, state aid, recapitalisation and fundamental rights.

The central principle is that Spanish banking rehabilitation is designed not simply to save a troubled bank, but to determine whether its viability can be restored while protecting critical functions, depositors and financial stability—and, where recovery is no longer feasible, to manage failure through an orderly legal process.
