Assume that the real, risk-free rate is expected to be constant at 2.1%, that the inflation rate is expected to be 3% a year for the next three years. then 5% a year thereafter, and that the default risk and liquidity premiums on all Treasury securities is equal to zero. Now assume that a 10-year Treasury bond has a yield that is 1.34% more than the yield on a 5 -year Treasury bonds. Given this information, determine the difference in the maturity risk premiums for the two bonds. 0.64% 0.54% 0.94% 0.84% 0.74%
