How to solve this Bond Valuation question

Setup

Setup

The half-year yield is 3.6%, while the semiannual coupon is 500r.

BV6=1000(r/2)a340.036+1000v34=9716.01r+300.45BV_6=1000(r/2)a_{\overline{34}|\,0.036}+1000v^{34}=9716.01r+300.45

Write the two adjacent post-coupon book values from their remaining coupons and par redemption.

BV7=1000(r/2)a330.036+1000v33=9565.79r+311.26BV_7=1000(r/2)a_{\overline{33}|\,0.036}+1000v^{33}=9565.79r+311.26

For a discount bond the book value increase in the seventh period is 4.36; solving that difference yields r = 0.0429.

4.36=BV7BV6=10.81150.22r4.36=BV_7-BV_6=10.81-150.22r

Answer

Answer

The annual coupon rate is therefore about 4.3%, choice C.

r=0.0429=4.3%(C)\boxed{r=0.0429=4.3\%\quad\text{(C)}}
