问题如下:
Based on the following information, what are the the risk-neutral and real-world default probabilities?
• Market price of bond is 92.
• Liquidity premium is 1%.
• Credit risk premium is 2%.
• Risk-free rate is 2.5%.
• Expected inflation is 1.5%.
• Recovery rate is 0%.
选项:
解释:
B The risk-neutral default probability is approximately 8% because the market price is 92% of par.
risk-neutral probability = real-world probability + credit risk premium + liquidity premium
8% = real-world probability + 2% + 1%
real-world probability = 8% - 3% = 5%
我的只能理解,中性定价里面,所有的spread都对CR进行补偿,这个时候CR大了,所以PD高,如果是objective的话, spread不止对CR进行补偿,还有别的东西,所以,PD相对就低了。就是扫一眼知道选B ,
还是不太明白你放的那个图,和这句话是怎么补偿的。讲道理RISK NATURAL PD= 1+3+2=6%,这个东西应该是spread的概念
如果套用这题,spread= 8%-2.5%=5.5%,如果是risk natural 的话5.5%全部补偿CR了,再减去1%的流动性4.5%就是objective
但是这么硬算又找不到答案。。。
