One-year Treasury security has the yield of 4.45%, and 6.50% for the two-year Treasury security. Suppose that one-year security does not have a maturity risk premium, but the two-year does have a maturity risk premium of 0.40%. What is the market's estimate of the one-year Treasury rate one year from now? (Hint: adjust the two-year rate by subtracting the maturity risk premium from the rate).
