The new measures seek to harmonise shock scenarios and modelling assumptions for banking stress tests, aiming for a stronger financial stability.
April 14th, 2026 – The European Commission has adopted a new delegated regulation (EU) 2026/856 aimed at harmonising how credit institutions and supervisors conduct stress testing across the Union. The act supplements the existing prudential framework under the Capital Requirements Directive (CRD), introducing detailed technical standards on supervisory shock scenarios, modelling assumptions and key parameters. Its objective is to ensure that risk assessments are consistent, comparable and sufficiently robust to capture potential systemic vulnerabilities within the EU’s banking system.
At the core of the regulation is the establishment of common supervisory shock scenarios, which define the types, severity and duration of adverse economic conditions (such as sharp GDP contractions, market dislocations or interest rate shocks) that institutions must apply when assessing their resilience. By prescribing a shared set of stress conditions, the regulation seeks to eliminate discrepancies between national practices and prevent institutions from relying on less stringent internal assumptions.
The act also introduces harmonised modelling and parametric assumptions. These include standardised inputs for macroeconomic variables, asset price movements and correlations between risk factors, as well as technical specifications on probability distributions and calibration methods. Such provisions are designed to limit methodological flexibility that could otherwise lead to underestimation of risks, thereby reinforcing supervisory convergence across Member States.
Another key element is the definition of what constitutes a “large decline” in financial metrics, including capital levels, profitability and asset valuations. By setting common thresholds, the regulation ensures that significant deteriorations in an institution’s financial position are identified consistently and trigger appropriate supervisory scrutiny. The results of these stress exercises must be reported to competent authorities and feed into the broader supervisory review and evaluation process.
Overall, the regulation strengthens the EU’s prudential toolkit by enhancing the reliability and comparability of stress testing outcomes. While it may increase compliance costs for institutions due to more detailed modelling requirements, it is expected to improve crisis preparedness and support financial stability by providing supervisors with a clearer and more uniform picture of risks within the banking sector. These measures also come during a time of major global economic instability, where disruptions to global supply chains are commonplace, so we can understand them not only as preventive but preparatory as well.
