Back-to-Back Interest Rate Swaps Explained in 3 Minutes

Customer demand for long-term fixed-rate financing is a long-standing challenge for banks. While business cycles ebb and flow, there is always a segment of customers who require 5+ year fixed-rate debt. At the same time, competition for these quality assets continues to grow across banks of all sizes and from many non-bank lenders.

This poses a problem for mid-sized and smaller banks. Meeting the customer's preference for fixed-rate financing often puts pressure on the bank’s balance sheet. Simultaneously, customers who are offered only floating-rate debt might take their business elsewhere.

What is an interest rate swap?

An interest rate swap is a contract between two parties to exchange interest payments. Each is calculated on the same principal amount (referred to as "notional amount") on a recurring schedule over a set period of time. One party typically pays a fixed interest rate, while the other party typically pays a floating interest rate. No principal (notional) amount is exchanged. The parties simply exchange, or swap, interest payments. A swap is a netted agreement, meaning that whichever party pays more interest in that period is the one who makes the payment.

What is a back-to-back interest rate swap?

A back-to-back swap is a common term to describe when a bank executes an interest rate swap with a borrower, and a second offsetting interest rate swap with a dealer counterparty.

Why should I consider using back-to-back swaps at my bank?

Swaps have always been a useful way for banks to manage risk. Currency risk, credit risk and interest rate risk can all be hedged, separating out the different types of risk inherent in a transaction so that the customer, or the bank, is only taking on selected risk, not the whole package. Offering a swap with a floating-rate loan to your customer allows the bank to separate the credit decision (do I want to lend for 5+ years to this customer) from the interest rate risk decision (am I comfortable taking 5+ years of fixed rate risk?).

How do back-to-back swaps work?

Back-to-back swaps work as follows: the bank enters into two separate transactions with the customer: 1) a floating-rate loan and 2) a companion fixed-rate swap with its customer. These transactions create a synthetic fixed-rate structure. For example, the customer borrows at floating rates, but because of the swap, effectively pays a fixed-rate on the loan. The bank then executes an offsetting swap with a swap dealer thereby leaving the bank with only the economic impacts of the floating-rate loan.

The swap rate includes a swap fee, which the bank earns to cover the costs to originate and service the swap with the customer and for the additional extension of credit.

The difference between the wholesale rate (reflecting the bank's credit quality and dealer mark-up) and the retail rate (reflecting where the bank gets done with their customer) is equal to the fee that the bank earns. The dealer pays the bank this sum within two business days of executing the swap. The swap fee depends on the size and structure of the deal and the customer’s credit.

Who uses back-to-back swaps?

Here are a few practical examples of back-to-back interest rate swaps:

  • A commercial real estate investor who wants long-term fixed-rate financing is provided a floating-rate loan and a swap
  • A company wants to lock-in the rate on an "evergreen" portion of its credit line and the bank offers a swap
  • A borrower who wants to lock-in a rate on future financing is offered a forward-starting swap

Size and term vary, but generally back-to-back swaps are $1 million or greater in notional and 5 years or longer in tenor.


Using back-to-back swaps, a bank can:

  • Meet its customer's financing preference without taking on unneeded interest rate risk
  • Earn fee income enhancing the bank's return on capital
  • Level the playing field with larger financial institutions offering swaps and non-bank lenders offering long-term fixed-rate debt
