The current term structure of interest rates is such that the one-year rate is 0.5%, the two-year rate is 1%, the three-year rate is 2% and thereafter the term structure is flat at 2.25%. Compute the one-year forward rate covering the period between the end of year 1 and the end of year 2. Compute the forward rate between the end of year 2 and the end of year 3 as well. Comment on the shape of the forward rate curve with reference to theories of the term structure of interest rates
