How does the rate cap replacement reserve work on a CRE bridge loan?

How the replacement reserve protects lender and disciplines sponsor

Multi-year bridge loans typically require the sponsor to maintain a rate cap covering the entire loan term. When the initial cap is shorter than the loan (the standard rolling structure), the loan documents require a cap replacement reserve to make sure the renewal cap is funded.

Mechanics: at closing, the lender estimates renewal cap cost using a forward model (current SOFR forward curve, current implied volatility, modeled strike at the renewal date). The estimated renewal cost is divided by the number of months between initial cap purchase and renewal date; that monthly amount is funded from operating cash flow into a lender-controlled escrow account.

Annual true-up: each year (or at lender option), the renewal cap cost model is refreshed against current market pricing. If the new model exceeds the prior estimate, the sponsor must true-up the under-funded amount within 30-60 days. If the new model falls below the prior estimate, the over-funded amount may be released to the sponsor or remain in the reserve as additional cushion (lender option).

Renewal execution: 60-90 days before cap expiration, the sponsor solicits new cap quotes (the standard RFP process to three-to-five hedge providers) and either (a) buys the new cap directly using sponsor cash and is reimbursed from the reserve, or (b) instructs the lender to draw the reserve and execute the cap purchase.

Under-funding remedies: if the reserve is materially under-funded relative to current market and the sponsor cannot true-up, the lender typically has the right to (a) accelerate the loan as a covenant breach, (b) draw on the carry guaranty, or (c) require additional sponsor equity as a condition of waiving the breach. Sponsors should track reserve adequacy quarterly to avoid surprise true-up demands.
