What Is the EBA EU-Wide Stress Test?

Every two years, the European Banking Authority puts the continent’s largest banks through a rigorous test of resilience. The EU-wide stress test simulates what would happen to bank balance sheets if a severe — but plausible — economic downturn were to occur. For risk officers, compliance teams, and financial institutions, understanding how this exercise works is essential to interpreting its findings and preparing for the supervisory consequences that follow.

This guide explains what the EU-wide stress test is, who runs it, how the methodology works, and what the 2025 exercise revealed about the state of European banking.

What Is the EU-Wide Stress Test?

The EU-wide stress test is a supervisory exercise that assesses how Europe’s banks would cope with a hypothetical economic crisis. It measures the impact of severe macroeconomic and financial shocks on bank solvency — specifically on core capital ratios — over a three-year period.

The EBA runs the exercise every two years in cooperation with the European Central Bank (ECB) and the European Systemic Risk Board (ESRB). It is not a pass-or-fail exam. There is no predefined capital threshold that banks must clear. Instead, the results feed directly into each bank’s Supervisory Review and Evaluation Process (SREP), where regulators decide on capital requirements and distribution constraints.

The exercise serves four objectives: assessing and comparing the overall resilience of EU banks to severe shocks; determining whether bank capital levels are sufficient to support the economy during periods of stress; fostering market discipline through the transparent publication of granular, bank-level data; and providing a quantitative input to the SREP process conducted by national supervisory authorities.

Who Runs the EU-Wide Stress Test?

The exercise involves close coordination among four groups of institutions, each with a distinct role. The EBA acts as the overall coordinator and develops the common methodology. The ESRB and ECB design the adverse macroeconomic scenario. National central banks provide the baseline projections. And the competent authorities — including the ECB’s Single Supervisory Mechanism for euro area banks — are responsible for quality-assuring the banks’ results.

How the Stress Test Methodology Works

The EU-wide stress test uses what the EBA calls a “constrained bottom-up” approach. Banks themselves calculate the projected impact of the scenarios on their balance sheets, but they do so within a tightly prescribed set of rules. Supervisors then scrutinise those projections for consistency and plausibility.

The methodology covers five core risk types. Use the tabs below to explore what each involves.

One critical assumption underpins the entire exercise: the static balance sheet. Banks must assume their balance sheet size and composition remain constant over the three-year horizon. They cannot assume they would issue new capital, de-risk their portfolio, or take other management actions in response to the stress. This deliberate conservatism ensures the stress test captures the full mechanical impact of the shocks.

The Two Scenarios: Baseline vs Adverse

Every stress test applies two scenarios over the same three-year horizon. The baseline reflects the most likely economic path — essentially the consensus forecast at the time the exercise is launched. The adverse scenario models a tail-risk event: severe, plausible, but unlikely.

The 2025 adverse scenario was slightly more severe than the 2023 exercise in GDP terms. It placed greater emphasis on geopolitical risk and trade disruption than previous exercises, reflecting the ESRB General Board’s risk assessment from late 2024. The scenario also included a detailed breakdown of gross value added (GVA) impacts across 16 economic sectors — enabling banks to model sector-specific credit losses more precisely.

What Happens with the Results?

The stress test does not produce a simple pass or fail verdict. Instead, its outputs serve as a key input to the Supervisory Review and Evaluation Process (SREP) — the annual supervisory assessment that determines each bank’s capital requirements.

The results influence capital planning in two ways. First, the projected CET1 capital depletion under the adverse scenario is the starting point for setting Pillar 2 Guidance (P2G) — the additional capital buffer that supervisors expect banks to hold above their binding requirements. Banks with larger capital depletions under stress can generally expect a higher P2G. Second, the qualitative assessment of a bank’s stress-testing processes — including data quality, governance, and model reliability — can influence Pillar 2 Requirements (P2R), which are legally binding.

In 2025, the aggregate results were broadly positive. The 64 tested banks started with a CET1 ratio of 15.76% and, even after absorbing €547 billion in losses over three years, ended the adverse scenario at 12.06% — a depletion of 370 basis points. This was considerably better than the 479 basis-point depletion seen in the 2023 exercise, driven primarily by stronger bank profitability and income generation.

History of the EU-Wide Stress Test

The EBA has been conducting EU-wide stress tests since 2011, though the format has evolved significantly over the years. The exercise was postponed in 2020 due to the pandemic, with banks redirected to focus on operational continuity. Key exercises and their sample sizes are summarised below.

Why the Stress Test Matters for Financial Institutions

The EU-wide stress test is not just a regulatory compliance exercise. Its outcomes have direct consequences for bank capital planning, dividend distribution, and strategic positioning. Banks that show significant capital depletion under stress may face restrictions on shareholder distributions, higher Pillar 2 capital buffers, or supervisory demands to improve their risk modelling capabilities.

For non-bank financial institutions, asset managers, and corporate treasurers, the published results provide a rare window into how individual banks and national banking systems would perform under severe economic conditions — information that is directly relevant for counterparty risk assessment, credit analysis, and portfolio allocation decisions.
