C哪里不对

NO.PZ2021120102000023

问题如下:

Which of the following statements best describes how a single-name CDS contract is priced at inception?

选项:

A.

If the reference entity’s credit spread trades below the standard coupon rate, the CDS contract will be priced at a premium above par because the protection buyer pays a “below market” periodic coupon.

B.

If the reference entity’s credit spread trades above the standard coupon rate, the CDS contract will be priced at a discount to par because the protection seller effectively receives a “below market” periodic premium.

C.

Similar to fixed-rate bonds, CDS contracts are initially priced at par with a fixed coupon and a price that changes over time as the reference entity’s credit spreads change.

解释:

B is correct. For example, if the reference entity’s credit spread trades at 1.50% versus a standard coupon rate of 1.00%, the CDS contract will be priced at a discount equal to the 0.50% difference multiplied by the effective CDS spread duration times the contract notional.

Under A, the contract is priced at a premium to par because the protection buyer is receiving an “above market” periodic premium.

请问C不对在哪里 我理解A B

嗨,爱思考的PZer你好:


C错就错在initially priced at par这个表述了。

CDS有fixed coupon,对于不同主体的CDS protection,初始价格不一定是par,只有初始spread=1%的投资级主体和初始spread=5%的投机级主体的CDS初始价格才等于par

比如一个初始spread=2%的投资级主体,根据CDS定价公式,p0=(1+(1%-2%)*Effdur)*NP<NP,它是折价发行的,并不是priced at par。

嗨,从没放弃的小努力你好:


A错在后面的below market periodic coupon,由于当前spread<fixed coupon,而buyer要支付fixed coupon,所以,是above market periodic coupon。
