Consider the following three bonds:
Bond | Coupon Rate | Maturity (years) | Price |
A | 0% | 1.0 | $947.5572 |
B | 7% | 1.0 | $1,014.8980 |
C | 5% | 1.5 | $981.4915 |
Assume that coupons are paid every 6 months and the face values of
all the bonds are $1,000.
(a) Suppose that the 0.5- and 1.5-year zero-coupon bonds are available. Determine their respective prices. (Keep 2 decimal places, e.g. xxx.12)
PZ0.5: PZ1.5:
(b) Determine the forward rate f 0.5,1 (in yearly term) on a 6-month Treasury bill 6 months from now. (Keep 4 decimal places, e.g. 0.1234)
(c) Determine the forward rate f0.5,1.5 (in yearly term) on a 12-month Treasury bill 6 months from now. (Keep 4 decimal places, e.g. 0.1234)
(d) Price the 1.5-year coupon bond 6 months from now. (Keep 2 decimal places, e.g. xxx.12)?
Answer 1) The price of a zero coupon Bond will calculated by discounting of maturity value of bond by effective interest rate ,
i.e P = M / (1+r)n
First we have to calculate Interest rate for the respective period as,
from Bond A, 947.55 = 1000/(1+S1)^1
=> S1 =0.05535
From Bond B , coupon is 7% , and matures in 1 year ,0.5 years we get 0.07*1000/2 = $35
so, 1014.898 = 35/(1+S0.5)^0.5 + 1035/(1+S1)
=> 1014.898 = 35/(1+S0.5)^0.5 + 1035/(1+0.05535)
=> S0.5 = 0.04851
From Bond C , Coupon is 5% , matures in 1.5 year ,0.5 years we get 0.05*1000/2 = $25
So, 981.4915 = 25/(1+0.04851)^0.5 + 25/(1+0.05535) + 1025/(1+S1.5)^1.5
=> S1.5 = 0.064407.
Price of zero coupon bond : P0.5 = 1000/(1+0.04851)^0.5 = $ 976.59
Price of zero coupon bond : P1.5 = 1000/(1+0.064407)^1.5 = $ 910.62
Answer 2) Forward rate f 0.5,1 .
(1+S1) = (1+f(0.5, 1))(1+S0.5)^0.5
(1+0.05535) = (1+f(0.5, 1))(1+0.04851)^0.5
=> f 0.5,1 = 0.3065.
Answer 3) Forward rate f 1,1.5
(1+S1.5) = (1+f(1,1.5))(1+S0.5)^0.5
(1+0.064407) = (1+f(1,1.5))(1+0.04851)^0.5
=>f 1,1.5 = 0.03949
