Answer:
Confidence index increases from 0.6721 to 0.7183
Step-by-step explanation:
The computation of the confidence index is shown below:
Initial Confidence Index is
= Aa-rated bonds yield ÷ Baa-rated bonds yield
= 4.1% ÷ 6.1%
= 0.6721
Since the yields on both bonds increase by 1.0%
So, the confidence index after increase in yield is
= (4.1% + 1%) ÷ (6.1% + 1%)
= 0.7183
So, Confidence index increases from 0.6721 to 0.7183
