Both Bond A and Bond B have 10 percent coupons, make semiannual payments, and are priced at par value. Bond A has 5 years to maturity, whereas Bond B has 10 years to maturity. If interest rates suddenly rise by 2 percent, what is the percentage change in the price of Bond A and Bond B? If rates were to suddenly fall by 2 percent instead, what would the percentage change in the price of Bond A and Bond B?
Please shows all the formula and steps. Don't round off until you get to the end.
Price of a bond is the sum of the PV of the expected cash flows | ||
from the bond if, it is held till maturity. | ||
The expected cash flows are: | ||
*The maturity value of $1000 receivable at maturity. | ||
*The interest payments, which constitute an ordinary annuity. | ||
The discount rate to be used is the market rate of interest. | ||
If the interest payments are semi-annual, the discounting is to be | ||
done semi-annually. | ||
1] | Price of bonds when interest rate is 10%+2% = 12.00%: | |
Price of Bond A = 1000/1.06^10+50*(1.06^10-1)/(0.06*1.06^10) = | $ 926.40 | |
% change in price of Bond A = 926.40/1000-1 = | -7.36% | |
Price of Bond B = 1000/1.06^20+50*(1.06^20-1)/(0.06*1.06^20) = | $ 885.30 | |
% change in price of Bond A = 885.30/1000-1 = | -11.47% | |
2] | Price of bonds when interest rate is 10%-2% = 8.00%: | |
Price of Bond A = 1000/1.04^10+50*(1.04^10-1)/(0.04*1.04^10) = | $ 1,081.11 | |
% change in price of Bond A = 1081.11/1000-1 = | 8.11% | |
Price of Bond B = 1000/1.04^20+50*(1.04^20-1)/(0.04*1.04^20) = | $ 1,135.90 | |
% change in price of Bond A = 1135.90/1000-1 = | 13.59% |
