How interest rate swaps work (and why they're worth it).

If you have a loan with a variable rate, you probably keep a close eye on interest rates. A change in interest rates effects your borrowing costs and can make it difficult to anticipate what you’ll pay month-to-month. Changes in variable rate indexes can make it difficult to forecast debt service levels. If you would like to secure a fixed cost of debt service but not move to a traditional fixed rate loan, an interest rate swap could be a good fit.

Interest rate swaps are a useful tool for hedging against variable interest rate risk. For both existing and anticipated loans, an interest rate swap has several strategic benefits. To make smart use of an interest rate swap, it helps to understand how a swap works. Here’s what you need to know:

How an interest rate swap works.

Ultimately, an interest rate swap turns the interest on a variable rate loan into a fixed cost, for example LIBOR (London Inter Bank Offered Rate).* It does so through an exchange of interest payments between the borrower and the lender. (The parties do not exchange a principal amount.)

With an interest rate swap, the borrower still pays the variable rate interest payment on the loan each month. For many loans, this is determined according to LIBOR plus a credit spread. Then, the borrower makes an additional payment to the lender based on the swap rate. The swap rate is determined when the swap is set up with the lender and is unchanging from month to month. Finally, the lender rebates the variable rate amount (calculated as the LIBOR portion of the rate), so that ultimately the borrower pays a fixed rate.

Ways to leverage a swap.

An interest rate swap is excellent for protecting against an expectation of higher interest rates. And, due to the nature of interest rate swaps, there are many additional advantages to be aware of and leverage. Here are a few:

  • Manage cash flow.
    Once you secure the swap rate, you’ll know exactly how much you’ll be paying each month. Let that certainty be the foundation for smart, strategic plans.

  • Access flexible prepayment penalties.
    In a fixed rate loan, you may pay a prepayment penalty if at some point you sell the financed property or your business and pay off your remaining outstanding loan balance. A variable rate loan does not have a prepayment penalty, but if you enter an interest rate swap and pay off your loan early, you would need to settle the swap contract at market value at that time. Because the contract is canceled at market value, you could either be in a liability position and owe something to the bank, or you could be in an asset position and receive a payment from the bank upon termination.

  • Secure a future rate.
    A traditional fixed rate loan can guarantee a rate in the short-term. When you complete a swap on a floating rate loan, it’s possible to lock in a fixed rate that will start on a date in the future. You may be able to secure a rate that would start months – or even years – later.

  • Complete a swap on a portion of the loan.
    A swap doesn’t have to be completed on the entirety of your loan. You can obtain an interest rate swap to secure a set rate on a portion of the loan, so that you still have a floating rate for the rest. This affords more flexible and creative options for your portfolio.

Things to consider.

While providing great solutions for managing borrowing costs, swaps have a few more moving parts than your traditional fixed rate loan structures. Here are a few considerations to discuss with your lender:

  • Documentation
    With your swap contact and the help of your lender, you must complete standard swap documentation before starting. The agreement doesn’t commit you to completing the swap.

  • Accounting
    Interest rate swaps with structures to match the terms of the initial loan may qualify for hedge accounting. Consult with your accountants and/or auditors to determine if hedge accounting is appropriate for your situation.

  • Regulatory
    The Wall Street Reform and Consumer Protection Act (the Dodd Frank Act) outlines eligibility and suitability requirements for any parties entering an interest rate swap agreement. Talk to your bank to confirm your eligibility.

An interest rate swap may seem intimidating at first, but once the mechanics are worked out it’s as simple as paying a fixed amount each month. If you’re interested in an interest rate swap, ask your relationship manager to put you in contact with one of our swap products specialists. It’s important to involve your relationship manager in any interest rate swap conversations, as they are most familiar with your credit portfolio. And, of course, an interest rate swap is a credit product subject to credit approval.

*Note: LIBOR is set to be replaced on December 31, 2021. The index and the process are still fully undetermined but it is expected to be a smooth transition that will not have a material impact to any existing interest rate swap contracts already in effect.
