Consider the following two bonds: a 5-year and a 10-year bond, each with a 7% coupon. Both bonds currently sell at par and coupon payments are made annually (i.e., one coupon payment per year).
(a) What is the current price of each bond?
Hint: answer does not require calculations; read description of bonds carefully to determine what price must be (10 points) Suppose you buy the 10-year bond. One year later, interest rates decrease to 5%.
(b) What will be the new price of the bond? (30 points)
(c) What rate of return would you have earned on the bond over the one-year period? (20 points)
(d) Which bond will have a higher rate of return over the year, the 5-year bond or the 10-year bond? Why? (5 points).
You don’t need calculations for this one and will not be given any points for a numerical answer; respond based on your understanding of interest rate risk (price sensitivity) in bonds.
a] | Current price of each bond is $1,000, as they sell at par. | |
b] | Price of a bond is the PV of the expected cash flows | |
from the bond if, it is held till matruity. | ||
The expected cash flows are the maturitry value of | ||
$1,000 and the annual interest [annuity]. | ||
Price of the bond one year later: | ||
5 Year bond: | ||
= 1000/1.05^4+70*(1.05^4-1)/(0.05*1.05^4) = | $ 1,070.92 | |
10 Year bond: | ||
= 1000/1.05^9+70*(1.05^9-1)/(0.05*1.05^9) = | $ 1,142.16 | |
c] | Rate of return earned on the bonds over the past one | |
year period. | ||
5 Year bond: | ||
= (70+1070.92-1000)/1000 = | 14.09% | |
10 Year bond: | ||
= (70+1142.16-1000)/1000 = | 21.22% | |
d] | The 10 Year bond will have a higher rate of return over | |
the year, as its price will rise more for a given decrease | ||
in market interest rates than in the case of the 5 Year | ||
bond. This is because as maturity of the bond increases | ||
it becomes more price sensitive. |
