Introduction: Interest rate hedge transactions
Businesses often protect themselves against risks through hedging transactions. Businesses enter into hedges in a variety of situations. For example, businesses may hedge commodity price risk, currency exchange rate risk or interest rate risk. This article focuses on interest rate risk.
Banks (and other lending institutions) typically make loans bearing interest at a floating rate. A business that must pay interest on its debt at a floating rate may want to hedge against increases to the floating rate. Businesses commonly utilize interest rate derivatives, such as interest rate swaps or caps as hedges.
For example, suppose a manufacturing company borrows funds from a bank under a loan agreement carrying an interest rate computed as the sum of (a) an interest rate index such as the Secured Overnight Financing Rate (SOFR) plus (b) a margin. If SOFR increases, the company’s quarterly cash interest payments will increase; if SOFR decreases, the company’s quarterly cash interest payments will decrease. The company, however, prefers fixed-rate exposure to variable-rate exposure. To effectively obtain fixed-rate exposure for all or a portion of its future interest payments, the company enters into a hedging transaction (with the same bank or a different bank or derivatives dealer).
Interest rate swaps
An interest rate swap is a contract between two parties that applies interest rates to a notional principal amount. Periodically (e.g., monthly or quarterly), one party is required to pay a fixed rate multiplied by the notional principal amount and the other party is required to pay a floating rate multiplied by the notional principal amount. The two payment amounts are netted; there is only one net payment requirement for each period. None of the notional principal amount is required at any time.
Where an obligor on floating-rate debt uses a swap to reduce its floating-rate risk, the swap requires the debtor to make fixed-rate payments to its counterparty (typically a bank or a derivative dealer, parties referred to in this article as banks), and the bank is required to make floating-rate based payments to the debtor. The floating-rate based payments that the debtor receives from the bank typically offset some or all of the floating-rate portion of the interest payment the debtor must make on its loan. As a result, the swap positions the debtor to make that portion of its required interest payments without exposure to increases in a floating-interest rate.
The bank typically does not charge its customer an upfront fee for an interest rate swap (unless one of the two—the bank or the customer—already owes a liability to the other, e.g., due to other derivatives or securities trades). Instead, the bank sets a fixed rate for the swap that it anticipates will enable it to earn a profit from the transaction. Payments are due from the bank to the debtor or vice versa for each period during the swap’s term; when the variable rate exceeds the fixed rate the bank must pay the debtor, and when the variable rate is less than the fixed rate the debtor must pay the bank.
