7. Consider a one-year coupon bond with face value of $100 and coupon payment equal to $10 paid every 6 months. The market interest rate on similar coupon
bonds is 12%.
SHOW ALL STEPS.
(a) Find the price of the one-year coupon bond.
(b) Assume a one-year zero coupon bond is priced at $93. Find the bond’s
yield to maturity.
(c) The current yield on 6 mo. bonds is 7%.
(d) Create a synthetic one-year zero-coupon bond from the coupon bond.
(e) Find the profitable arbitrage possibility. Show carefully why this works by
filling in the table below to show the cash flows.

(a) Price = PV of cashflows discounted at the market interest rate of 12%
= ($5 / (1 + 0.12) ^ 0.5) + ($105 / (1 + 0.12) ^ 1)
= 4.72 + 93.75
= $98.47
(b) We have to find the interest rate that will make $93 equal to $100 in one years time :
YTM = (100 / 93) - 1 = 0.0752688, or 7.527 %
(c) To create a synthetic coupon bond, we need to replicate the cash flows of the coupon bond and discount the 6-month cash flow at 7% and the one-year cash flow at 12%
($5 / (1 + 0.07) ^ 0.5) + ($105 / (1 + 0.12) ^ 1)
PV = 98.58
A zero-coupon bond priced at $98.58 will replicate the coupon bond
