Rate caps (and the 2022-24 horror stories)

Rate caps looked like routine closing items until borrowers had to replace them while benchmark rates were higher, projects were behind plan, and liquidity was already thin.

Then the small line item took the weight of the whole capital stack.

A cap is not a magic ceiling on the mortgage. It is a separate contract with a strike, covered notional, counterparty, calculation method, and expiration date. It can offset part of a floating-rate increase. It cannot repair NOI, extend maturity, or produce the cash required for its own replacement.

The 2022-24 lesson is historical and mechanical. It is not a prediction about where rates go next.

The strike does not include the spread

Most floating-rate commercial loans charge an index plus a spread. The index is often SOFR or an average of SOFR. The New York Fed describes SOFR as a broad measure of overnight borrowing secured by Treasury securities. A loan may use 30-day Average SOFR, Term SOFR, or another contractually defined version. Read the definition; the labels are not interchangeable.

Assume the loan rate is 30-day Average SOFR plus 3.00%, and the cap strike is 3.00%. If the index rises above 3.00%, the cap provider generally owes a payment based on the amount above the strike, the covered notional, and the contract’s calculation rules.

The 3.00% loan spread remains. Economically, the cap may hold the indexed portion near 3.00%, leaving an effective rate near 6.00% before fees, timing differences, basis risk, and any uncovered principal.

A “3% cap” does not usually mean a 3% mortgage. The phrase cuts off the part of the line still tied to the borrower.

The cap softens $450,000 and leaves a $600,000 hole

Take a $20 million interest-only loan at 30-day Average SOFR plus 3.00%.

• At 1.00% SOFR, the note rate is 4.00%, or roughly $800,000 of annual interest.
• At 5.25% SOFR, the note rate is 8.25%, or roughly $1,650,000 of annual interest.
• With a 3.00% strike on the full $20 million notional, the cap’s annualized offset is roughly 2.25% of $20 million, or $450,000.
• Net of that simplified offset, interest lands near $1,200,000, equivalent to roughly 6.00%.

The cap prevented about $450,000 of annualized pain. It did not restore the original $800,000 debt-service budget. The spread remains, operating expenses may have risen, and cap payment mechanics may not align perfectly with the loan’s billing period.

Now add the failure that hurt borrowers in practice. The loan runs three years, but the cap expires after two. Renovations take longer, NOI misses the refinance target, and the replacement quote is a hypothetical $900,000 instead of the $75,000 carried in the original budget. The property has $300,000 of unrestricted cash.

The result is a $600,000 hole before operations, extension fees, or a principal paydown. Someone contributes cash, the lender takes control of cash, or the loan defaults. Those are the available lines. A belief about future rates is not another source of funds.

Why replacement protection became expensive

The 2022-24 distress was not only about benchmark rates rising. The forward curve moved, cap providers priced a higher probability of future payouts, and replacement protection became expensive at the same time many properties had less liquidity.

Freddie Mac’s research on floating-rate seniors housing loans describes the mechanics: caps can expire before loan maturity, replacement costs rise with the forward curve, and the impact of more expensive hedges became acute beginning in the second half of 2022.

Fannie Mae’s SARM guidance offers a concrete example of lender treatment. When a cap expires before maturity, the required cap reserve is at least 110% of the current replacement cost. That is a program rule, not a universal rule. It shows that cap replacement is an ongoing funding exposure, not a closing souvenir.

Match the hedge paper to the loan paper

Pull the actual documents and connect each obligation:

1. Promissory note and loan agreement: Confirm the exact index, spread, floor, default rate, cap strike, replacement deadline, and consequences of failing to replace.
2. Cap confirmation: Verify effective date, termination date, strike, notional schedule, payment dates, day-count convention, and whether the cap covers the entire outstanding balance.
3. Assignment and collateral documents: Confirm the lender has the required rights to cap payments and that the counterparty acknowledgement was delivered.
4. Counterparty requirements: Check whether the provider is approved and what happens after a ratings downgrade.
5. Reserve and cash-management agreement: Find the required monthly deposits, recalculation dates, reserve shortfall cure, sweep trigger, and permitted uses.
6. Extension provisions: Confirm whether exercising an extension requires a new cap, a lower strike, a longer term, a fee, a paydown, or fresh covenant compliance.

Then obtain the current replacement quote. The original invoice proves only what protection cost in the past. The live quote is the tension gauge.

Questions that reveal who carries the shortfall

Ask who funds a cap shortfall. Ask whether the sponsor has liquidity outside the property. Ask what happens if replacement cost and the extension fee arrive in the same month. Ask whether the refinance works at the capped rate rather than the opening rate. Ask whether cap payments are trapped in a lender-controlled account.

Also ask:

• Does the cap expire before initial maturity or any extension?
• Does its notional match the outstanding balance throughout the term?
• What contractual event requires early replacement?
• How often is the reserve recalculated?
• What happens under the loan documents if replacement is late?

“The lender required a cap” explains why the document exists. It does not prove the borrower can keep it in place.

This is education, not legal, tax, or derivatives advice. Cap language is deal-specific. Read the executed documents with qualified counsel and a hedge adviser before money moves.
