Systemic risk contributions: a credit portfolio approach

Düllmann, Klaus; Puzanova, Natalia - Deutsche Bundesbank - 2011

We put forward a Merton-type multi-factor portfolio model for assessing banks' contributions to systemic risk. This model accounts for the major drivers of banks' systemic relevance: size, default risk and correlation of banks' assets as a proxy for interconnectedness. We measure systemic risk...

Measuring business sector concentration by an infection model

Düllmann, Klaus - Deutsche Bundesbank - 2005

Results from portfolio models for credit risk tell us that loan concentration in certain industry sectors can substantially increase the value-at-risk (VaR). The purpose of this paper is to analyze whether a tractable "infection model" can provide a meaningful estimate of the impact of...
