In the work of the Basel Committee there has been a tradition ofdistinguishing market from credit risk and to treat both categories independentlyin the calculation of risk capital. In practice positionsin a portfolio depend simultaneously on both market and credit riskfactors. In this case, an...

We propose a new method for analysing multi-period stress scenarios for portfolio credit risk more systematically than in the current practice of macro stress testing. Our method quantifies the plausibility of scenarios by considering the distance of the stress scenario from an average scenario....

We give a precise operational definition to three requirements the Basel Committee on Banking Supervision specifies for stress tests: Plausibility and severity of stress scenarios as well as suggestiveness of risk reducing actions. The basic idea of our approach is to define a suitable region of...

We criticize the popular view that separately calculating regulatory capital for market and credit risk yields a conservative aggregate risk assessment. We show that this view depends on a flawed intuition about diversification effects that arise between subportfolios. If a bank’s portfolio...
