【FRM每日一题】二级：信用风险测量与管理（8）
备考FRM二级 | 2015-11-30
The spread on a one-year BBB-rated bond relative to the risk-free treasury of similar maturity is 1.4%. It is estimated that the contribution to this spread by all noncredit factors (e.g., liquidity risk, taxes) is 0.4%. Assuming the loss given default rate for the underlying credit is 40%, what is, approximately, the implied default probability for this bond?
A. 1.67%
B. 2.33%
C. 3.50%
D. 2.50%
Answer: D
The probability of default equals the credit risk spread divided by the loss given default. PD = spread/LGD. Here, the spread due to credit risk equals 1.4% - 0.4% or 1.0% and the loss given default is 40%. The probability of default is then 2.5%.
