This overview article provides an introduction to the 2025 Macroprudential Stress Test Extension Report (MaSTER), released as the 32nd edition of the Macroprudential Bulletin, which investigates how the EU-wide stress test and its extensions provide a broader assessment of the systemic vulnerabilities of euro area banks. The 2025 EU-wide stress test results are expanded via a top-down model-based toolkit to assess additional risks, perform policy simulation exercises, and present novel approaches to gauging the severity of the adverse scenario.
