请问这个题如何解答？没有LGD 的情况下毫无任何思路。

  1. FRM II
  2. Credit Risk Measurement And Management

NO.PZ2020033003000067

问题如下：

Jane is asked to calculate the risk-neutral and real-world default probabilities of the bond A. She collected the following datas. The market price of the bond A with a face value of 100 is 95. The liquidity premium and credit risk premium are 2% and 1% respectively. The coupon rate of newly issued treasury bond is 2.5%. The expected inflation is 0.8%.

选项：

Risk-neutral probability
Real-world probability
A.
Risk-neutral probability 2%
Real-world probability 5%
B.
Risk-neutral probability 5%
Real-world probability 2%
C.
Risk-neutral probability 5%
Real-world probability 4.2%
D.
Risk-neutral probability 4.2%
Real-world probability 5%

解释：

B is correct.

考点：Infer Credit Risk from Corporate Bond Prices

解析：risk-neutral default probability 100-95=5%

risk-neutral probability = real-world probability + credit risk premium + liquidity premium

real-world probability = 5% - 2%-1% = 2%

这个题正常应该怎么解答呢，使用简化的公式吗？LGD一般是需要给出来的吧。风险中性PD 为什么是实际违约概率加上信用风险和流动性风险的SPREAD？谢谢

嗨，爱思考的PZer你好：


同学你好，

这题没有给RR，所以不能用精确的方法做，只可以用近似的方法：

这道题有些特殊，需要根据Notes给出算法来做：市场给出的定价是95，债券面值100，说明该债券风险中性违约概率是5% - (100-95)/100。

这个风险中性违约概率包含了：流动性风险溢价、违约风险溢价和实际的违约风险。




或者这么理解：这个债券总的风险溢价（流动性风险+违约风险）是2% +1% = 3%，理论上应该值97块钱（3%的折价）。但是市场定价只有95块钱，投资人只愿意付95块钱。这少的2块钱（2%），就是现实世界中的违约概率了。
