- Abstract
- Conventional credit risk models understate tail risk by centering on mean default probabilities and neglecting distributional and sectoral heterogeneity. We propose a Quantile Probability of Default (QPD) framework based on unconditional quantile regressions estimated on flow default rates from five million non-financial firms across nine countries, conditioned on macro- and sectoral scenario covariates standard in stress testing. The tail exhibits three- to five-fold stronger sensitivity than at the median, revealing non-linearities and asymmetric sectoral propagation of credit risk. We validate the performance of our model across crisis periods and benchmark models to confirm the framework’s robustness and prudential efficiency. Under the European Central Banks’s 2025 increasing geopolitical and trade tensions scenario, the QPD identifies higher tail vulnerabilities in construction, trade, hospitality, and real estate. The framework embeds distributional estimation into stress testing, advancing scenario-based assessment of sectoral credit risk for policy and prudential applications.

- Abstract
- This paper provides an overview of stress-testing methodologies in Europe, with a focus on the advancements made by the European Central Bank’s Financial Stability Committee Working Group on Stress Testing (WGST). Over a four-year period, the WGST played a pivotal role in refining stress-testing practices, promoting collaboration among central banks and supervisory authorities and addressing challenges in the evolving financial landscape. The paper discusses the development and application of various stress-testing models, including top-down models, macro-micro models and system-wide models. It highlights the integration of new datasets and model validation efforts as well as the expanded use of stress-testing methodologies in risk and policy evaluation and in communication. The collaborative efforts of the WGST have demystified stress-testing methodologies and fostered trust among stakeholders. The paper concludes by outlining the future agenda for continued improvements in stress-testing practices.

- Abstract
- This paper investigates how the monetary policy transmission channels change once the economy is in a low interest rate environment. We estimate a nonlinear model for the euro area and its five largest countries over the period 1999q2-2019q1 and allow for the effects of monetary policy shocks to be state dependent. Using smooth transition local projections, we examine the impulse responses of investment, savings, consumption, and the output gap to an expansionary monetary policy shock under normal and low interest rate regimes. We find evidence for a macroeconomic reversal rate related to the substitution effects becoming weaker relative to the income effects in a low interest rate regime. In this regime the effects of monetary policy shocks are either less powerful or reverse sign compared with a normal rate regime.
