Calvin and Andre both have bonds they bought at par value and pay 7% coupons. Calvin’s bond has ten years to maturity and Andre’s bond has 20 years to maturity. If interest rates suddenly rise to 9%, what is the approximate change in value of Calvin’s bond?
Multiple Choice
13.01%
14.95%
-13.01%
19.79%
-18.40%
14.21%
-14.95%
Let the face value of the bond be 100
Coupon Rate = 7%
Coupon Amount = Face Value * Coupon Rate = 7
No of years to maturity = 10
For a bond trading at par, interest rate will be equal to the
coupon rate of the bond.
Therefore current interest rate = 7%
Interest rate rises to 9% :
Face Value = 100
Coupon Amount = 7
Interest Rate = 9%
No of Years = 10
Calculation of bond price :
Value of Bond = Present Value of Coupons + PV of Principal Amount
= [PVAF (9%,10) * 7] + [PVIF (9%,10) * 100]
= (6.4177 * 7) + (0.4224 * 100)
= 44.92 + 42.24
= 87.16
Present Value Factor have been calculated as = (1/1+r)n
Where
r= Required rate of Return (Discount rate)
n= No of Periods
PVAF (9%,20) is calculated by adding the PV Factor of 9% for 20
years.
Change in bond Price = Bond price when int rate increase to 9% -
Current bond price
= 87.16 – 100
=
-12.84
% Change In bond Price = Change in bond Price/Current bond
price * 100
= -12.84/100 * 100
= -12.84%
Since option c) i.e -13.01% is closest. Option c) is the
answer.
