Nominal and real rates and yield curves A firm wishing to evaluate interest rate behavior has gathered data on the nominal rate of interest and on inflationary expectations for five U.S. Treasury securities, each having a different maturity and each measured at a different point in time during the year just ended. (Note: Assume that the risk that future interest rate movements will affect longer maturities more than shorter maturities is zero; that is, there is no maturity risk.) These data are summarized in the following table. U.S. Treasury Security Point In Time Maturity Nominal Rate of Interest Inflationary Expectation A Jan. 7 2 years 12.6% 9.5% B Mar. 12 10 years 11.2 8.2 C May 30 6 months 13.0 10.0 D Aug. 15 20 years11.0 8.1 E Dec. 30 5 years 11.4 8.3 Using the preceding data, find the real rate of interestat each point in time
