What it is

The European Banking Authority (EBA) is an EU agency created after the financial crisis to develop and maintain a single rulebook for banks across the whole European Union. Its remit spans all Member States, not only those inside the Banking Union, which distinguishes it from the ECB's Single Supervisory Mechanism and from the Single Resolution Board. The EBA does not directly supervise or resolve banks; it writes the detailed rules that supervisors and resolution authorities then apply, and works to make their application consistent.

Its core output is regulatory and implementing technical standards, which, once adopted by the European Commission, are legally binding across the EU. Alongside these it issues guidelines and recommendations addressed to authorities and institutions on a "comply or explain" basis, and it produces reports, opinions and the EU-wide transparency and stress-testing exercises that underpin market discipline.

Its role in the resolution framework

Much of the technical substance of the resolution framework is filled in by EBA standards and guidelines. In the recovery and resolution field the EBA has developed standards and guidance on the content of recovery plans and resolution plans, on the assessment of resolvability, on the minimum requirement for own funds and eligible liabilities (MREL), on the criteria for identifying critical functions, and on the valuation carried out in resolution. It also frames aspects of the supervisory review and evaluation process that determine capital requirements. In this way the EBA translates the broad provisions of the directives and regulations into operational detail that resolution authorities such as the Single Resolution Board and national resolution authorities apply case by case.

The EBA additionally holds a mediation role. Where national authorities disagree — for example within a resolution or supervisory college — the EBA may facilitate agreement and, in defined circumstances, conduct binding mediation to settle the dispute. This supports consistent cross-border decision-making, a persistent challenge in resolving banking groups that operate in several states.

The EBA is established by Regulation (EU) 1093/2010, which sets out its objectives, tasks and powers, including the drafting of technical standards, the issuing of guidelines and recommendations, and its role in binding mediation and in ensuring the consistent application of EU law. The substantive rules it elaborates are contained in instruments such as the Capital Requirements Regulation and Directive and the Bank Recovery and Resolution Directive, which frequently mandate the EBA to develop the accompanying standards.

Practical relevance for banks and investors

For banks, the EBA's standards and guidelines determine much of the operational detail of capital, MREL and resolution planning that they must satisfy, regardless of which authority supervises or would resolve them. For investors, the EBA is a source of harmonised definitions and of comparable, published data through its transparency exercises. Its work is the connective tissue that keeps supervision and resolution consistent across the whole EU, inside and outside the Banking Union.
