Problem 6-18. Yield curves. Suppose the inflation rate is expected to be 6.15% next year, 4.3% the following year, and 2.3% thereafter. Assume that the real risk-free rate, r*, will remain at 2.45% 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. Furthermore, 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. a. Calculate the interest rate on 1-year Treasury securities. Round your answer to two decimal places. % b. Calculate the interest rate on 2-year Treasury securities. Round your answer to two decimal places. % c. Calculate the interest rate on 3-year Treasury securities. Round your answer to two decimal places. % d. Calculate the interest rate on 4-year Treasury securities. Round your answer to two decimal places. % e. Calculate the interest rate on 5-year Treasury securities. Round your answer to two decimal places. % f. Calculate the interest rate on 10-year Treasury securities. Round your answer to two decimal places. % g. Calculate the interest rate on 20-year Treasury securities. Round your answer to two decimal places. % Problem 6-13. Default risk premium The real risk-free rate, r*, is 2.45%. Inflation is expected to average 3.35% a year for the next 4 years, after which time inflation is expected to average 4.95% a year. Assume that there is no maturity risk premium. An 11-year corporate bond has a yield of 11.45%, which includes a liquidity premium of 0.4%. What is its default risk premium? Round your answer to two decimal places. _____________%
