Counterparty Risk and the Pricing of Defaultable Securities

ABSTRACT Motivated by recent financial crises in East Asia and the United States where the downfall of a small number of firms had an economy‐wide impact, this paper generalizes existing reduced‐form models to include default intensities dependent on the default of a counterparty. In this model, firms have correlated defaults due not only to an exposure to common risk factors, but also to firm‐specific risks that are termed “counterparty risks.” Numerical examples illustrate the effect of counterparty risk on the pricing of defaultable bonds and credit derivatives such as default swaps.
