This paper introduces a stress test of the corporate credit portfolios of 24 large German banks by a two-stage approach: First, a macro-econometric model is used to forecast the impact of a substantial increase of the user cost of business capital for firms worldwide on three particularly...

In attempting to promote bank stability, the Basel Committee on Banking Supervision (2006) provides a framework that seeks to control the amount of tail risk that large banks take in their trading books. However, banks around the world suffered sizeable trading losses during the recent crisis....

Regulatory capital for trading book positions includes two components that cover different risks but apply to the same portfolio, one for market risk and one for credit risk. Similar approaches are common in banks’ internal models for economic capital. Although it is known that joint market...

We develop a macroeconomic portfolio stress test that is specifically geared towards small and medium-sized banks. We combine a credit risk stress test which simulates credit impairments via a CreditMetrics type multi-factor portfolio model with an income stress test in the form of dynamic panel...

Reverse stress tests are a relatively new stress test instrument that aims at finding exactly those scenarios that cause a bank to cross the frontier between survival and default. Afterward, the scenario which is most probable has to be identified. This paper sketches a framework for a...

We study a conflict of interest faced by universal banks that conduct proprietary trading alongside their retail banking services. Our dataset contains the stock holdings of each and every German bank and of their corresponding retail clients. We investigate (i) whether banks deliberately push...

This study investigates the bank competition-stability nexus using a unique regulatory dataset provided by the Deutsche Bundesbank over the period 1994 to 2010. First, we use outright bank defaults as the most direct measure of bank risk available and contrast the results to weaker forms of bank...

We use a Diamond/Dybvig-based model with two banks operating in separate regions connected by a common asset market in which banks and sophisticated depositors invest. We study the effect of a potential run (crisis) and subsequent fire sales on the asset price in both the crisis and no-crisis...

We provide empirical evidence on the relevance of systemic risk through the interbank lending channel. We adapt a spatial probit model that allows for correlated error terms in the cross-sectional variation that depend on the measured network connections of the banks. The latter are in our...

We use a unique data set that comprises each bank’s bids in the Eurosystem’s main refinancing operations and its recourse to the LOLR facility (a) to derive banks’ willingness-to-pay for liquidity through a one-week repo and (b) to show that a bank’s willingness-to-pay is a good...
