RT Journal Article SR Electronic T1 Impact of Correlated Default Risk on Credit Portfolios JF The Journal of Fixed Income FD Institutional Investor Journals SP 9 OP 19 DO 10.3905/jfi.2001.319301 VO 11 IS 3 A1 Sanjiv Ranjan. Das A1 H. Gifford Fong A1 Gary Geng YR 2001 UL https://pm-research.com/content/11/3/9.abstract AB Markets are evidencing increasing systemic risk, and the credit market is no exception. 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.
