Case Corporate Bonds – They are More Complex Than You Think

1. How should Jill go about explaining the relationship between coupon rates and bond prices? Why do the coupon rates for the various bonds vary so much?

Jill should explain the relationship between coupon rates and bond prices by calculating the price of the bonds, which have similar features except coupon rate.

Let’s compare ABC Energy issuer with the coupon rate 5% and 0% (the same with rating and YTM) IssuerMaturityFace ValueCoupon RateRatingYieldPrice% Change ABC Energy2010005%AAA2%\$1,490.54 49.05%

ABC Energy2010005%AAA3%\$1,297.55 29.75%
ABC Energy2010005%AAA5%\$1,000.00 0.00%
ABC Energy2010005%AAA6%\$885.30 -11.47%

ABC Energy2010000%AAA2%\$672.97 -32.70%
ABC Energy2010000%AAA3%\$553.68 -44.63%
ABC Energy2010000%AAA5%\$376.89 -62.31%
ABC Energy2010000%AAA6%\$311.80 -68.82%
