Problem 10 Suppose the inflation rate is expected to be 6.15% next year, 4.45% the following year, and 3.2% thereafter. Assume that the real risk-free rate, r, will remain at 2.15% and that maturity risk premiums on Treasury securities rise from zero on very short-term bonds (those that mature in a few days) to 0.2% for 1-year securities. Furthemore, maturity risk premiums increase 0.2% for each year to maturity, up to a limit of 1.0% on 5-year or longer-term T-bonds. 1. Calculate the interest rate on 5 -year Treasury securities. Round your answer to two decimal places. 2. Calculate the interest rate on 10-year Treasury securities. Round your an swer to two decimal places. 3. Cakulate the interest rate on 20 -year Treasury securities. Round your answer to two decimal places
