An interest-rate agreement is an agreement between two parties whereby one party, for an upfront premium, agrees to compensate the other at specific time periods if a designated interest rate, called the reference rate, is different from a predetermined level. When one party agrees to pay the other when the reference rate exceeds a predetermined level, the agreement is referred to as an interest-rate cap or ceiling. The agreement is referred to as an interest-rate floor when one party agrees to pay the other when the reference rate falls below a predetermined level. The predetermined interest-rate level is called the strike rate.
The terms of an interest-rate agreement include
- The reference rate
- The strike rate that sets the ceiling or floor
- The length of the agreement
- The frequency of settlement
- The notional principal amount

In an interest-rate swap, two parties (called counterparties) agree to exchange periodic interest payments. The dollar amount of the interest payments exchanged is based on a predetermined dollar principal, which is called the notional principal amount. The dollar amount that each counterparty pays to the other is the agreed-upon periodic interest rate times the notional principal amount. The only dollars that are exchanged between the parties are the interest payments, not the notional principal amount. In the most common type of swap, one party agrees to pay the other party fixed-interest payments at designated dates for the life of the contract. This party is referred to as the fixed-rate payer. The other party, who agrees to make interest rate payments that float with some reference rate, is referred to as the floating-rate payer. The frequency with which the interest rate that the floating-rate payer must pay is called the reset frequency. Read the rest of this entry »
The interest-rate swap was developed in late 1981. By 1987, the market had grown to more than $500 billion (in terms of notional principal amount). What is behind this rapid growth? As our asset/liability application earlier demonstrated, an interest-rate swap is a quick way for institutional investors to change the nature of assets and liabilities or to exploit any perceived capital market imperfection. The same applies to borrowers such as corporations, sovereigns, and supranationals.
In fact, the initial motivation for the interest-rate-swap market was borrower exploitation of what were perceived to be “credit arbitrage” opportunities because of differences between the quality spread between lower- and higher-rated credits in the U.S. and Eurodollar bond fixed-rate market and the same spread in these two floating- rate markets. Basically, the argument for swaps was based on a well-known economic principle of comparative advantage in international economics. Read the rest of this entry »
