问题如下:
Suppose Bank Z lends EUR 1 million to X and EUR 5 million to Y. Over the next year, the PD for X is 0.2 and for Y is 0.3. The PD of joint default is 0.1. The loss given default is 40% for X and 60% for Y. What is the expected loss of default in one year for the bank?
选项:
A. EUR
0.72 million
B. EUR
0.98 million
C. EUR
0.46 million
D. EUR
0.64 million
解释:
ANSWER: B
The joint PD does not matter for the ECL. This is , or EUR 0.98 million.
还是不明白为什么不用joint pd这个条件。如果加上X和Y同时default的credit loss,credit loss应该比B选项要更大吧。
