Suppose that the current 1-year rate (1-year spot rate) and expected 1-year T-bill rates over the following three years (i.e., years 2, 3, and 4, respectively) are as follows: 1R1 = 2.58%, E(271) = 3.85%, E(371) = 4.35%, E(471) = 5.85% Using the unbiased expectations theory, calculate the current (long-term) rates for one-, two-, three-, and four-year-maturity Treasury securities. (Do not round intermediate calculations. Round your answers to 2 decimal places.) Years Current (Long-term) Rates 1 % 2 % 3 % 4 %
