We characterize asset return linkages during periods of stress by an extremal dependence measure. Contrary to correlation analysis, this non-parametric measure is not predisposed towards the normal distribution and can account for non-linear relationships. Our estimates for the G-5 countries...

In this note we demonstrate that in affine models for bilateral exchange rates, the nature of return interdependence during crises depends on the tail properties of the fundamentals’ distribution. We denote crisis linkages as either strong or weak, in the sense that the dependence remains or...

This paper derives indicators of the severity and structure of banking system risk from asymptotic interdependencies between banks%u2019 equity prices. We use new tools available from multivariate extreme value theory to estimate individual banks%u2019 exposure to each other (%u201Ccontagion...

Capital adequacy regulations or quantity restrictions on bank portfolios put forward by the Basle Committee on Banking Supervision have virtually become an international standard of prudential regulation. Recent proposals aim at extending this approach to market risks, in particular to foreign...
