Which has a higher percentage change in price? Why?

Explanation / Answer

Price of Bill bond now = 1000

Price of ted Bond now = 1000

As they are priced at par, they must have ytm equal to coupon rate that is 7%

After rates change,

Price of Bill bond=70/1.09+70/1.09^2+70/1.09^3+1000/1.09^3=949.3741

%change in price of Bill bond=(949.3741-1000)/1000=-5.063%

Price of Ted bond=70/1.09+70/1.09^2..............70/1.09^20+1000/1.09^20=70/0.09*(1-1/1.09^20)+1000/1.09^20=817.4291

%change in price of Ted bond=(817.4291-1000)/1000=-18.257%

Ted has higher percentage change in price because it has higher duration or interest rate sensitivity..Higher the maturity higher is the duration and Ted bond has higher maturity thus has higher duration
