Suppose the term structure of interest rates has these spot interest rates: r₁ = 5.4%, r₂ = 5.2%, r₃ = 5.0%, r₄ = 4.8%, and r₅ = 6.4%. a. What will be the 1-year spot interest rate in three years if the expectations theory of term structure is correct? b. If investing in long-term bonds carries additional risks, then how would the risk equivalent of a 1-year spot rate in three years relate to your answer to part (a)?
