FRM Part II · FRM Exam Part II · Financial Correlation Modeling - Bottom-Up Approaches
A risk team compares the empirical behavior of default correlation and equity correlation. Which statement is consistent with the evidence discussed for correlation in credit markets?
Default correlations tend to rise in recessions and when credit conditions deteriorate. Common macroeconomic factors push defaults to cluster in downturns, so models assuming constant default correlation understate portfolio credit losses during stress.
- ADefault correlations tend to increase in recessions and when credit conditions worsenCorrect
- BDefault correlations are lower in recessions than in expansions
- CDefault correlations are independent of the economic cycle
- DDefault correlations are always zero for investment-grade firms
Explanation
Empirically, default correlation is higher in recessions and periods of stress, since firms are affected by common macro factors. This parallels equity correlation behavior. Stating that it falls or is cyclical-independent contradicts the evidence.
