Historically, there were two basic motivations for swaps: to exploit perceived market inefficiencies and to attempt to obtain cheaper financing. Both of these motivations are based on the concept that the financial markets are inefficient. This fact, unfortunately, is no longer true. Today, the swap markets are mature and offer few arbitrage opportunities. Swap markets are now viewed as being more operationally efficient and a more flexible means of packaging and transforming cash flows than any other method. The reasons given now for using the swap markets are to: reduce transactions costs, avoid costly regulations, and maintain privacy.
