Callable Swap

Key Takeaways

• A callable swap is an interest rate swap where the fixed-rate payer can terminate the contract early.
• The call feature in a callable swap makes it more expensive than a regular interest rate swap.
• Callable swaps are useful for those who wish to hedge against interest rate changes.
• The fixed rate payer might use a callable swap to refinance if interest rates drop.
• Consider matching callable swaps with callable debt to manage debt costs effectively.

What Is a Callable Swap?

A callable swap is a financial derivative that allows a fixed interest rate payer to swap payments with a variable rate payer, with the unique option to terminate early. The main advantage of a callable swap is that it provides flexibility for the fixed rate payer to refinance or cancel the swap if market conditions become more favorable.

The difference between this swap and a regular interest rate swap is that the payer of the fixed rate has the right, but not the obligation, to end the contract before its expiration date. Another term for this derivative is a cancellable swap.

Investors might choose callable swaps to manage interest rate risks or align with the terms of callable debt. We'll explain how these swaps work and the benefits they provide to investors.

How a Callable Swap Works

There is little difference between an interest rate swap and a callable swap other than the call feature. However, this does dictate a different pricing mechanism which accounts for the risk the payer of the floating rate must take. The call feature makes it more expensive than a plain vanilla interest rate swap. This cost means the fixed rate payer will pay a higher interest rate and possibly need to pay additional funds to purchase the call feature.

Although many of the mechanics are similar, a callable swap is not the same as a swap option, which is better known as a swaption.

Reasons to Consider a Callable Swap

An investor might choose a callable swap if they expect the rate to change in a way that would adversely affect the fixed rate payer. For example, if the fixed rate is 4.5% and interest rates on similar derivatives with similar maturities fall to perhaps 3.5%, the fixed rate payer might call the swap to refinance at that lower rate.

Callable swaps often accompany callable debt issues, especially when the fixed rate payer is more interested in debt cost rather than the maturity of that debt.

Another reason to use this derivative is to protect against the early termination of a business arrangement or asset. As an example, a company secures financing for a factory or land at a variable interest rate. They may then seek to lock in a fixed rate with a swap if they believe there is a chance it will sell the financed asset early due to a change in plans.

The additional cost of the call feature is similar to an insurance policy for the financing.
