Suppose the real risk-free rate is 3.00%, the average expected future inflation rate is 6.60%, and a maturity risk premium of 0.10% per year to maturity applies, i.e., MRP = 0.10%(t), where t is the years to maturity. What rate of return would you expect on a 1 year Treasury security, assuming the pure expectations theory is NOT valid? (Include the cross-product term, i.e., if averaging is required, use the geometric average.) (Round your final answer to 2 decimal places.)
