Swaps as Theoretical Equivalents of Other Derivatives

Interest Rate Swaps as a Series of Forward Rate Agreements

An interest rate swap can be recreated by a series of forward rate agreements (FRAs).

A difference between an interest rate swap and a series of FRAs is that the swap will have a single fixed rate, but the forward contracts will be priced at different interest rates based on the slope of the yield curve (unless, of course the yield curve is flat, then a single rate would hold for the series of FRAs).
