这是我的回答:
if 12-year government yield increases by 30 bps
Yield spread remains unchanged as the similar duration is still 8 years, so it is 1%
G spread would change, new interpolated 9 year government bond = 1.675%, so g spread= 2.5%-1.675%=0.825%
there is no price change under yield spread as the spread remains the same
g spread price change = -7.5*(-0.00075)=0.005625=0.5625%
g spread is more accurate as if yield spread were to be used, there is no price change which doesnt truly reflect ths rate change impact. as the spread decreases for a bank bond, the price increases.
我的问题是,我答的点只围绕了因为9年期国债的改变而造成的g spread的改变,而没有像老师这样回答了benchmark+spread=Yc,请问可以吗?
