What are 'Swaps'
A swap is a cash-settled contract between two parties to exchange (or "swap") cash flow streams. As long as the present value of the streams is equal, swaps can entail almost any type of future cash flow. They are most often used to change the character of an asset or liability without actually having to liquidate that asset or liability. For instance, an investor holding common stock can exchange the returns from that investment for lower risk fixed income cash flows - without having to liquidate his equity position.
The difference between a forward contract and a swap is that a swap involves a series of payments in the future, whereas a forward has a single future payment.
Two of the most basic swaps are:
- Interest Rate Swap - This is a contract to exchange cash flow streams that might be associated with some fixed income obligations. The most popular interest rate swaps are fixed-for-floating swaps, under which cash flows of a fixed rate loan are exchanged for those of a floating rate loan.
- Currency Swap - This is similar to an interest rate swap except that the cash flows are in different currencies. Currency swaps can be used to exploit inefficiencies in international debt markets.
For instance, assume that a corporation needs to borrow ¥100 million yen and the best rate it can negotiate is a fixed 6.7%. In the U.S., lenders are offering 6.45% on a comparable loan. The corporation could take the U.S. loan and then find a third party willing to swap it into an equivalent yen loan. By doing so, the firm would obtain its euros at more favorable terms. Cash flow streams are often structured so that payments are synchronized, or occur on the same dates. This allows cash flows to be netted against each other (so long as the cash flows are in the same currency). Typically, the principal (or notional) amounts of the loans are netted to zero and the periodic interest payments are scheduled to occur on that same dates so they can also be netted against one another.
