Answer:
A one-year bond has an interest rate of 5% today. Investors expect that in one year, a one-year bond will have an interest rate equal to 7%. Investors expect that in two years, a one-year bond will have an interest rate equal to 9%. According to the expectations theory of the term structure of interest rates, in equilibrium, a three-year bond today will have an interest rate equal to 7%.
Step-by-step explanation:
The current interest rate on one year bond = 5%
The forward interest rate on one year bond = 7%
The forward interest rate on one year bond = 9%
We can now calculate the interest rate on a three-year bond as below:
Interest rate = [Current interest rate on one year bond + Forward interest rate (7%) on one year bond + Forward interest rate (9%) ]/3
Interest rate = [5 +7+9]/3 = 21/3 = 7%
Therefore,
The interest rate on a three-year bond is equal to 7%.
