Choose a swap if you expect to hold the loan to term and want a fixed payment; choose a cap if a sale, refinancing or large paydown is plausible. A swap turns a floating rate into a fixed one with no premium at closing, but it has a market value that moves with rates: if rates fall and you repay the loan early, you owe a termination payment that can be large. A cap costs a premium at closing and pays you only when the base rate rises above an agreed strike; below it, you keep the benefit of falling rates and can refinance or sell without owing anything.

- Best fit
- Swap for a long hold; cap when a sale or refinancing is likely
Two different instruments doing a similar job
Most lower-middle-market term loans from banks and private credit funds float: a base rate such as SOFR plus a fixed spread, reset monthly or quarterly. A hedge is a separate contract that changes what the company effectively pays on the base rate. It never changes the spread or the loan itself. The SOFR vs Prime comparison explains the base rates, and fixed vs variable rate covers the choice before any hedge comes into it.
An interest rate swap is an exchange of payments. The company agrees to pay a fixed rate on a notional amount and to receive the floating base rate on the same amount. The floating payment it receives offsets the floating base rate on the loan, so its net cost is the fixed swap rate plus the loan's spread. It is, in effect, a fixed-rate loan built from two contracts. The glossary entry on swaps defines the terms.
An interest rate cap is an option the company buys. It pays a premium at closing. For the life of the cap, whenever the base rate is above an agreed strike, the cap provider pays the company the difference on the notional amount. Whenever the base rate is below the strike, nothing happens and the company pays the floating rate like any unhedged borrower. It is insurance against a rise, not a fixed rate.
A swap is cheap to enter and can be expensive to leave. A cap costs money to enter and nothing to leave.
Side by side
| Interest rate swap | Interest rate cap | |
|---|---|---|
| What it does | Converts the floating base rate to a fixed rate | Sets a ceiling on the base rate; below it, the rate floats |
| Cost at closing | None paid in cash; the provider's margin and credit charge are built into the fixed rate | A premium, paid once, often funded from loan proceeds |
| Cost while in place | Net settlement each period: you pay when the base rate is below the swap rate, you receive when it is above | Nothing further; the cap pays you when the base rate is above the strike |
| If rates fall | No benefit: you still pay the fixed rate | Full benefit: you pay the lower floating rate |
| If rates rise | Fully protected on the notional | Protected above the strike; exposed between today's rate and the strike |
| Ending it early | A termination payment, owed by you or to you depending on where rates are; can be a large cost | No payment owed; the cap can be left to expire, sold or assigned |
| Credit exposure | Two-way: the provider is exposed to you, so the swap is usually secured by the loan's collateral | One-way: once the premium is paid you owe nothing, so no ongoing credit line is needed |
| Who it suits | A borrower who will hold the loan to the swap's end and values a fixed payment | A borrower who may sell, refinance or pay down early, or who expects rates to fall |
Where a swap costs you: breakage
A swap has a market value from the day it is signed. That value is roughly the difference between the fixed rate you locked in and the fixed rate the market would quote today for the remaining term, applied to the remaining notional over the remaining years. If rates have fallen since you signed, the swap is worth money to the provider, and ending it early means paying that value. If rates have risen, the provider owes you.
The trap is that the loan and the swap are separate contracts. A loan with no prepayment penalty still carries one in practice if a swap sits beside it, because paying off the loan does not end the swap; it has to be terminated at its market value. Owners who sell, refinance into an SBA loan or pay down from a large customer payment find this out in the payoff figures. The loan's own exit costs, covered in prepayment penalty structures, come on top.
A worked example in plain numbers. A company swaps a notional of 5,000,000 for five years. Two years later it sells the business, and fixed rates for the remaining three years have fallen by one percentage point. As a rough estimate before discounting and before any amortization of the notional, the termination payment is one point on 5,000,000 for three years: about 150,000, owed at closing of the sale and deducted from the seller's proceeds. Had rates risen by the same amount instead, the company would have received about that much.
| What happens after signing | Swap, held to term | Swap, ended after year two | Cap, held to term | Cap, ended after year two |
|---|---|---|---|---|
| Rates fall | Pays the fixed rate; misses the fall | Pays a termination cost | Pays the lower floating rate; premium is sunk | Nothing owed; cap has little resale value |
| Rates flat | Pays the fixed rate as planned | Small cost or gain, depending on the curve | Pays the floating rate; premium is sunk | Nothing owed; cap may have some resale value |
| Rates rise | Protected; pays the fixed rate | Receives a termination payment | Protected above the strike | Nothing owed; cap can be sold for its value |
So match the swap's term and notional to the loan's expected life, not its stated maturity. A swap for the full term of a loan the owner expects to refinance in two years is a bet that rates will not fall before then. A flat notional on an amortizing loan leaves the company paying fixed in later years on money it no longer owes; ask for a notional that follows the repayment schedule.
Where a cap costs you: the premium and the gap
A cap's cost is its premium, set by four things: how close the strike is to today's base rate, how long the cap runs, the size of the notional, and how volatile the market expects rates to be. A strike near today's rate is expensive; a high strike is cheap and protects only against a severe rise. Because the premium is paid at closing, it competes with every other use of cash in sources and uses.
The second cost is the gap between today's rate and the strike. Between the two, the company is unhedged. A lender that requires a hedge to protect its coverage covenant will care where the strike sits, and may set a maximum strike in the credit agreement. The page on lender hedging requirements explains how those covenants are written and how a rate rise works through debt service coverage.
What the premium buys is freedom. A company with a cap can refinance, sell or pay down whenever it likes and owes the cap provider nothing; if rates have risen, the cap can be sold or assigned. A collar sits between the two: the company buys a cap and sells a floor, so the premium falls or disappears, but it gives up the benefit of rates falling below the floor, and the floor can carry its own termination value.
What lenders require, and the details that bite
Many floating-rate acquisition and recapitalization loans require the borrower to hedge a stated share of the term loan for a stated period, as a covenant to be met within a set time after closing. Revolvers and SBA loans rarely carry the requirement. SBA does limit variable 7(a) rates, at the base rate plus 3% for loans above $350,000, but that limit applies to the lender's spread, not the base rate. It is not a rate cap in the hedging sense: a variable 7(a) loan still moves with the market.
Where a hedge is required, check these points before signing:
- Instrument choice. Whether the credit agreement allows a cap or a collar, or only a swap. Lenders earn revenue on swaps, and some default to them.
- Counterparty. Whether you can buy the hedge from any qualified provider or only from the lender or its affiliate. A swap with the lender or its affiliate is usually secured by the same collateral as the loan. A swap with another provider shares that collateral only if the credit agreement names it as a permitted secured hedge; otherwise the provider will want security of its own, which the intercreditor terms then have to address.
- The floor mismatch. If the loan has an interest rate floor and the swap does not, then when the base rate falls below the floor the company pays the floor on the loan but receives less than the floor on the swap. Its all-in cost rises above the fixed rate it thought it had. A swap with a matching floor costs slightly more and closes the gap.
- Cross-default. A swap is usually cross-defaulted to the loan, so a missed swap payment is a loan default, and a loan default can trigger termination of the swap at its market value. See cross-default.
How to choose
Start from what is likely to happen to the loan, not from a view on rates. The market's forecast is already priced into the swap rate. The better question is how long the loan will really be outstanding at its current size.
- Long hold, steady business, tight budget. A swap gives a known payment and the most protection per unit of cost. Match the notional to the amortization and the term to the expected hold.
- Acquisition platform with add-ons planned. The debt will be refinanced or upsized as the platform grows. A cap, or a swap shorter than the loan, avoids paying breakage every time the structure changes. The delayed-draw vs revolver comparison covers how that growth debt is committed.
- Owner planning a sale within a few years. A cap. A swap termination cost comes out of sale proceeds at the worst moment to negotiate it.
- Large paydown expected from an asset sale, an earnout received, or excess cash flow. A cap, or a swap on a notional that excludes the portion expected to be repaid. The excess cash flow sweep page explains why that portion is often mandatory.
Transparent's financing model shows coverage at closing rates and at higher base rates, so the hedge is sized against figures a lender can reproduce. It is part of the lender package; how we underwrite sets out the tests. Of the 1,800+ lenders in the book, 1,148 write term and private credit, the lenders most likely to ask for a hedge.
Common questions
- Is a swap free because there is no upfront premium?
- No. The provider's margin and a charge for your credit risk are built into the fixed rate it quotes, and the swap can carry a termination cost if you end it early after rates fall. The cost is real; it is just not paid at closing.
- Can I refinance a loan that has a swap on it?
- Yes, but the swap does not end when the loan is repaid. It has to be terminated at its market value, which you pay if rates have fallen since you signed and receive if they have risen, or transferred to the new loan if the new lender and the swap provider agree.
- What happens to a cap if I pay the loan off early?
- Nothing is owed. The cap can be left to expire, sold for whatever value it has left, or in some cases assigned to a buyer or new lender. The premium already paid is not refunded.
- Which is better if I think rates will fall?
- A cap, because you keep the benefit of lower rates and can refinance without owing anything. A swap locks in today's expectation, and if rates do fall you both miss the benefit and owe a termination cost if you leave early.
