In the work of the Basel Committee there has been a tradition of distinguishing market from credit risk and to treat both categories independently in the calculation of risk capital. In practice positions in a portfolio depend simultaneously on both market and credit risk factors. In this case,...

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...

We propose a new approach to assess systemic financial stability of a banking system using standard tools from modern risk management in combination with a network model of interbank loans. We apply our model to a unique data set of all Austrian banks. We find that correlation in banks' asset...
