I ran into a question that gave some zero coupon rates and asked to calcuate forward rate. For example, they zero coupon rates for 1 year, 2 year and 3 year bonds. THen asked to calcuate the 1 year forward rate 2 years from now… So the answer is Y3^3 / Y2^2
THen I ran into an identical question but this time they provided spot rates for 1, 2 and 3 years with identical calcuations.
So the method to calcuates forward rates with both spot rates and zero coupon rates? they are the same, zero coupon and spots?
