M-PRESS-CreditRisk: Microprudential and Macroprudential Capital Requirements for Credit Risk under Systemic Stress

M-PRESS-CreditRisk is a novel stress testing approach that can help authorities gauge banks’ capital adequacy related to credit risk. For the first time, it combines the assessment of microprudential capital requirements under Pillars 1 and 2 and macroprudential buffers in a unified, coherent framework. Its core element is an advanced credit portfolio model—SystemicCreditRisk—built upon a rich, nonlinear dependence structure for correlated bank portfolios. The model is applied to a sample of 12 systemically important German banking groups and delivers measures for systemic credit risk and the banks’ contributions to it in both baseline and stress scenarios.
