Correlated default is thus an important feature models must account for in credit portfolios. To complement the growing literature on theoretical models to capture correlated default, the authors explore the implications of correlated default for credit portfolios. Ex ante default probabilities are found to be strongly correlated, and regime-dependent; ignoring these features understates the risk profile of credit portfolios. Rating agencies must include correlated default in their analysis of debt pools.
