I. Three Phases of Integration

Phase 1 - 1986-1999: Adaptation
Spain joins EEC 1986. Supervisory functions conferred on Banco de España since 1962, but fully Europeanized. Banco de España joined European System of Central Banks (ESCB) 1 Jan 1999. Law 13/1994 Autonomy of Banco de España transposes ECB independence.

Phase 2 - 1999-2012: Integration without governance
Spanish cajas expanded with cheap ECB funding, no European supervision. Spanish regulatory system largely mirrors legal framework in other EU Member States but supervision remained national - fatal flaw.

Phase 3 - 2012-2024: Banking Union Governance
June 2012: Spain requests €100bn ESM assistance for banks. Memorandum of Understanding (MoU) forces governance revolution:

1. Law 9/2012 and Law 10/2014 on ordering, supervision and solvency - transposes CRD IV / CRR
2. Creation of FROB as Spanish resolution authority but under SRB
3. SAREB (bad bank)
4. Council Regulation (EU) No 1024/2013 conferring specific tasks on ECB - SSM starts 4 Nov 2014

Today governance is dual:

II. Governance Principles imposed by EU

1. Independence and Fit & Proper:
ECB now does suitability tests for Spanish bank directors under SSM. Banco de España cannot oppose ECB decision.

2. Single Rulebook:
CRR directly applicable, no Spanish gold-plating allowed. Example: infringement case C-210/25 Commission v Spain 19 March 2025: Spain failed to transpose Directive (EU) 2021/2167 on credit servicers and credit purchasers. Commission asks CJEU to declare Spain failed obligations - shows integration is enforced by infringement.

3. Resolution vs Bail-out:
Before 2014, Spain bailed out Bankia with €22bn public money. After BRRD, Banco Popular resolution 7 June 2017 - first full SRB resolution. Shareholders and AT2 wiped out, sold to Santander for €1. No taxpayer money. Spanish courts (Audiencia Nacional, Supreme Court) rejected 200+ challenges, accepting SRB has exclusive competence.

III. Key Case Laws

A. Constitutional Governance Cases:

Case T-204/11 Spain v Commission ECLI:EU:T:2015:91 and C-360/11 Commission v Spain
Spain challenged Commission state aid decisions on cajas recapitalisation. CJEU confirmed Commission has wide discretion under Art.107(3)(b) to impose governance conditions: reduction of branches, ban on dividends, replacement of management. Spain must comply even if it violates national corporate law.[2015][2013]

Case C-212/11 Jyske Bank Gibraltar Ltd v Administración del Estado (25 April 2013) - Request from Tribunal Supremo Spain
Jyske Bank Gibraltar operating in Spain under freedom of services refused to report suspicious transactions to Spanish SEPBLAC, arguing only Gibraltar FSA competent.
CJEU: Prevention of use of financial system for money laundering Directive 2005/60 Art.22(2) allows host Member State (Spain) to require credit institutions operating under freedom of services to report directly to host FIU. Spanish AML governance prevails over home state.

Requirement to report suspicious financial transactions applicable to credit institutions - Institution operating under rules on freedom to provide services.

This is cornerstone of integrated AML governance.

B. Banking Governance through Consumer Law - ECJ uses governance to protect financial stability:

Case C-125/18 Marc Gómez del Moral Guasch v Bankia SA - Grand Chamber 3 March 2020 - IRPH Governance
Mortgage interest varied according to reference index based on mortgage loans granted by Spanish savings banks, index provided by Spanish law.

Tribunal Supremo asked if IRPH clause excluded from unfairness test under Art.1(2) Directive 93/13 because it reflects mandatory statutory provision.

ECJ: No, IRPH is not mandatory; bank could offer other index. National court must verify transparency and potential unfairness. Governance failure of Spanish cajas index becomes EU unfair terms issue.

This judgment forced Banco de España to reform Circular 5/2012 on transparency and governance of reference rates.

Case C-869/19 Unicaja Banco SA
Request from Tribunal Supremo on principles of equivalence and effectiveness. ECJ held Spanish procedural limits on restitution of floor clauses contrary to EU law. Governance of Spanish courts must adapt to EU effectiveness.

C. Recent SRM Governance Litigation:

Case C-551/22 - Grand Chamber 18 June 2024 - SRB Resolution Procedure
Appeal on Economic and monetary policy - Banking Union - Regulation 806/2014 - Single resolution mechanism - Resolution procedure applicable where entity is failing or likely to fail - Art.18(7) - Adoption by Single Resolution Board of resolution scheme - Endorsement by Commission.

CJEU clarified governance: SRB scheme + Commission endorsement = challengeable act, but shareholders must sue within 2 months at General Court, not Spanish courts. Confirms centralisation of Spanish banking governance in Brussels.

D. BBVA-Sabadell Merger - 2024-2025 Infringement

The European Commission has initiated infringement proceedings against Spain over its imposition of restrictive conditions on BBVA's €12 billion takeover of Banco Sabadell, marking pivotal confrontation between national sovereignty and EU single market principles. ECB Banking Supervision granted prudential approval in Sept 2024, concluding merged entity would maintain sufficient capital, liquidity and good governance despite concerns

Spanish Government (via CNMC) imposed conditions to protect Catalonia SMEs and branches. Commission says violates Art.21 SSMR and free movement of capital (Art.63 TFEU) - only ECB can assess prudential governance, Spain cannot add political conditions. Pending case will be next landmark.

IV. Current Governance Model in Spain

Spanish Law 10/2014 Art.29-32 requires banks to have:

1. Board with independent directors, risk, audit, remuneration, nomination committees
2. Risk appetite framework approved by ECB
3. Internal capital adequacy (ICAAP) and liquidity (ILAAP) supervised jointly by JST (Joint Supervisory Teams ECB + Banco de España)
4. Remuneration capped under CRD V - variable <100% fixed, malus/clawback

Failure triggers ECB early intervention (Art.27 BRRD) - ECB can remove Spanish board members directly.

In short, Spain moved from Banco de España monopoly governance to co-governance JST model where ECB decides and Banco de España executes, and from political cajas governance to fit & proper European governance.
