Answer:
Coupon rate = 0.08402 or 8.402%
Explanation:
To calculate the price of the bond, we need to first calculate the coupon payment per period. We assume that the interest rate provided is stated in annual terms. As the bond is a semi annual bond, the coupon payment, number of periods and semi annual YTM will be,
Coupon Payment (C) = x
Total periods (n)= 16.5 * 2 = 33
r or YTM = 7.7% * 1/2 = 3.85% or 0.0385
The formula to calculate the price of the bonds today is attached.
Using the bond price formula and the available values, we calculate the coupon rate to be,
1065 = x * [( 1 - (1+0.0385)^-33) / 0.0385] + 1000 / (1+0.0385)^33
1065 = x * (18.50739407) + 287.4653284
1065 - 287.4653284 = x * 18.50739407
777.5346716 / 18.50739407 = x
x = 42.012 rounded off to $42.01
If the semi annual coupon payment is $42.01, the annual coupon payment will be 42.01 * 2 = $84.02
The coupon rate on bonds is = 84.02 / 1000
Coupon rate = 0.08402 or 8.402%
