The one-year probabilities of default and the recovery rate of bond A are 5% and 60% respectively, while for bond B are 7% and 50%. Calculate the one-year expected credit loss of this portfolio. Give an assumption that the probability of joint default is 0.7% and the default correlation is 20%.
选项:
A.$ 1,200,000
B.$ 1,400,000C.$ 2,600,000
D.$ 3,270,000
解释:
C is correct.
考点: Credit VaR
计算: EL(A)=60*0.05*(1-0.4)=1.2m
EL(B)=40*0.07*(1-0.5)=1.4m
1.2+1.4=2.6m
跟correlation 没有关系
课程哪里有说到和correlation没有关系?求指路
