Corridors for Construction Loans

Caps are flexible but can be expensive, swaps are restrictive but have no upfront cost, and collars fall somewhere in the middle. There’s one other structure that we haven’t covered yet – corridors.

If a borrower wanted to put protection in place, retain flexibility, and do so at a reduced cost, a corridor is a structure to consider. Corridors are just a combination of caps, one bought, and one sold, with the primary intent of obtaining cap like protection at a reduced cost. These are frequently executed when one or more of the following are true:

• There’s no lender requirement to hedge.
• Borrower believes rate expectations are accurate or overdone.
• The goal is to obtain some protection, but borrower is comfortable with the risk of a higher rate.
• Borrower wants to hedge a longer term, but vanilla caps are too expensive.
• Retaining prepay flexibility is important.

When a cap is purchased, some portion of the cost paid is attributed to volatility/uncertainty. When a higher strike cap is also sold, a portion of the volatility is recouped, helping offset the cost of the initial purchase. Corridors are typically most beneficial in environments where a spike in volatility drives cap costs higher, or for longer term hedges.

As you learned in our resource The Hidden Driver of Cap Cost, costs generally increase exponentially with term, since each subsequent month has a greater level of uncertainty than the previous. For this reason, some developers prefer corridors since a hedge going out 3+ years can be structured at a reduced cost. The savings are often viewed as a cushion against rising rates that must be eroded before they’re worse off.

What happens when I go to prepay. Do I face any sort of penalty?

Nope. Since the lower strike you purchased is always worth more than the higher strike you sold, the cap always has a NPV greater than or equal to $0.

• If rates are well below the strikes when the loan is paid off, the corridor can easily be terminated but is likely worthless.
• If rates are elevated, the corridor could be terminated, and the remaining residual value recouped.

Sounds like corridors check a lot of boxes. What’s the catch?

There are a couple of major considerations to keep in mind:

• Since corridors are a combination of two caps, they don’t put a hard ceiling on rates. Therefore, if rates exceed the higher/sold strike, your net rate begins increasing bp for bp. Said another way, the maximum payout you can receive from a corridor is equal to the difference between the higher and lower strikes, whereas a vanilla cap theoretically provides protection to infinity.
• Since they don’t put a hard ceiling on rates, corridors don’t satisfy lender hedge requirements.

My lender isn’t requiring a hedge and I just want some protection. How do corridors look cost wise currently?

Below, on the left, we’ve outlined current pricing for a few structures for our hypothetical construction loan. For reference, on the right, we’ve included pricing for 3.50%, 4.00%, and 4.50% strike vanilla caps.


If the buy 3.50% / sell 5.00% structure was executed, it would behave like this:

• If SOFR is below 3.50%, neither cap pays out.
• If SOFR is above 3.50% but below 5.00%, the bank owes borrower the difference between the bought strike and SOFR. It feels like a 3.50% vanilla cap, but the borrower paid 30% less.
• If SOFR exceeds 5.00%, both caps come into play and are effectively a 1.50% drag on SOFR. In other words, if SOFR resets at 10%, the net rate will be 8.50%.

The last scenario above concerns me most about the strategy. What are my options if I execute a corridor and rates begin to rise unexpectedly?  

Current market expectations put SOFR at 3.20% in July 2026, meaning the buy 3.50% / sell 5.00% isn’t currently projected to pay out. If the rate outlook shifts materially higher in the future, there are several options that can be used to further limit your risk.

Layer on a third “disaster” protection cap

This is referred to as a capped corridor. For example, a third cap at 6.50% could be layered on, resulting in a max potential rate of 5.00%. While it may turn out to be more expensive than a vanilla interest rate cap at a 5.00% strike would have been, it does put a hard ceiling on your rate. More about capped corridors in our resource here.

“Buy to close” the higher sold strike

Under this option, you effectively purchase a cap at 5.00% to match the strike you sold. The net result is a ceiling on SOFR at 3.50%. All else equal, a 5.00% cap would be more expensive than a 6.50%, so this option would be more expensive than the previous, but obviously results in a lower capped rate.

Layer on a second corridor

The net rate begins to increase bp for bp when SOFR goes above 5.00%. If for example a buy 6.00% / sell 8.50% corridor was layered on, the risk is further limited. Under the 10% SOFR scenario, the net rate paid would be 6.00% (1.50% net payout from the first structure and 2.50% net payout under the second).

Layer on a swap

This is more restrictive due to the future potential breakage, but also avoids any additional out-of-pocket costs. If market rate expectations for the period of June 2026 – June 2028 jumped 1.75%, the swap rate would be around 5.00%. However, if SOFR is back above 5.00%, the corridor would also be paying out 1.50%.

5.00% swap – 1.50% corridor payout = 3.50% net rate

This is not an exhaustive list, and with the benefit of hindsight, it may be that none of the options look better than the vanilla 3.50% cap did at closing. However, there are numerous levers that can be pulled to further derisk down the road should you choose to execute a corridor today.

Tell me about structuring considerations.

Like caps, swaps, and collars, you can pretty much structure them however you’d like – there are just tradeoffs. A wider range between the bought and sold strike results in a higher cost (but more protection) than a tighter range of strikes. For example, the 3.50% / 5.00% cost is $245k whereas the 3.50% / 4.50% cost is $205k.

Shorter term corridors also have a smaller cost benefit than longer terms where there’s a larger volatility component. To help illustrate this, below we’ve broken down the cost of a vanilla cap at 3.50% and a 3.50% / 5.00% corridor for our hypothetical construction loan.


In the example above, the corridor costs $105k less than the cap. In order for the borrower to be worse off with the corridor, rates would need to be ~0.14%+ above 5.00% (or 5.14%+) between July 2026 and July 2028. To materialize, rates would need to be almost 2.00% above current market expectations.

The savings on longer-term corridors are greater but so are the potential range of outcomes. Below we’ve outlined what happens if we add on another year of term to our 3.50% / 5.00% example. The corridor costs $230k less than the vanilla cap and the breakeven point increases slightly to ~0.18% (or 5.18%+ SOFR).

Conclusion

Given the uncertainty around timing of draws and the ultimate sale/refi, corridors are a good alternative to caps since they’re cheaper but still retain flexibility. This is especially true when there’s no lender hedge requirement and borrower isn’t concerned about obtaining protection to infinity.
