Suppose 1-year Treasury bonds yield 4.00% while 2-year T-bonds yield 4.40%. Assuming the pure expectations theory is correct, and thus the maturity risk premium for T-bonds is zero, what is the yield on a 1-year T-bond expected to be one year from now? Round the intermediate calculations to 4 decimal places and final answer to 2 decimal places. O 4.80 O 5.71 O 3.79 O 5.09 O 5.23
