Interest Rate Risk in CRE: Caps, Swaps, Collars, and the 2026 Hedging Discipline

Key Takeaways

CRE Rate Caps vs Credit-Card Rate Caps

Before going further: this article is about interest rate caps as institutional CRE-debt hedging instruments — SOFR-indexed derivative contracts purchased by commercial real estate borrowers to limit upside on floating-rate loans. It is not about the consumer credit-card interest rate caps that surfaced in 2025 federal legislation (the Sanders / Lummis / Hawley / Brown proposals to cap consumer credit-card APRs at 10–18%). Those bills are unrelated regulatory proposals in the consumer-credit space; they share vocabulary with CRE rate caps and nothing else.

If you arrived here looking for the credit-card-rate-cap legislative track, Congress.gov and the American Bankers Association are the better resources. The math, mechanics, ISDA framework, pricing data, and hedge-accounting discussion below apply to institutional CRE hedging only.

Why CRE Borrowers Hedge

Hedging is the institutional response to a structural reality of CRE debt: most floating-rate paper is indexed to SOFR, and SOFR moves — sometimes violently. Between 2020 and 2023, the NY Fed SOFR reference rate moved from 0.05% to a peak above 5.30%, a 105x move that tripled debt service on every floating-rate bridge loan outstanding. For sponsors who modeled SOFR as a static input, the math broke. For sponsors with a rate cap at a tight strike, the cap paid; the deal cleared; the equity survived. The instrument earned the premium.

Three audiences need to understand CRE interest rate hedging. Bridge-loan sponsors and value-add operators manage SOFR + spread exposure on transitional assets; rate caps are usually a lender requirement, and cap renewal economics now drive whether the deal can extend. Permanent CRE borrowers and corporate-finance teams use interest rate swaps to fix the rate on bank or insurance-company term loans, converting a floating-rate liability into a fixed-rate equivalent without paying the CMBS spread. Asset managers and treasury teams face hedge accounting under ASC 815: the choice between cash-flow hedge designation, fair-value hedge designation, or no designation materially changes income-statement volatility at the fund level.

The other reason borrowers hedge is that lenders require it. Most bridge lenders require a rate cap at a strike not more than 100–200 bps above the going-in SOFR + spread, with the cap term covering the initial loan term plus extension periods. The lender's logic is debt-yield certainty: if SOFR moves 300 bps, the lender needs to know the property's NOI can still service the debt at the new rate. The cap is the mechanism that makes the lender's debt-yield underwriting stick. Bank permanent-term-loan lenders prefer swaps because the bank wants a fixed economic return regardless of how the borrower books it — the swap converts the borrower's floating-rate obligation into a fixed cash flow for the bank's balance sheet.

The Hedging Toolkit: Caps, Swaps, Collars, Swaptions

Four instruments matter for institutional CRE rate-risk hedging. Each answers a different question. The decision tree depends on the loan structure (floating vs fixed, bridge vs perm), the borrower's MTM appetite, the lender's requirements, and the cost the borrower is willing to pay for certainty.

The four-instrument decision tree for CRE rate-risk hedging. Each answers a different question; picking the right one for the loan structure and risk appetite is the first institutional discipline.

The institutional pattern: most CRE hedges are caps or swaps. Collars and swaptions are situational — they require sophisticated borrowers, larger balances, and specific market conditions to justify the complexity. A bridge-loan sponsor at $25–50M notional almost always uses a vanilla cap. A bank-perm borrower at $50–200M almost always uses a vanilla swap. The collar and swaption use cases are covered below.

Rate Caps in Detail

A rate cap is a strip of European-style call options on SOFR. Each option (a "caplet") pays at a specific reset date if SOFR exceeds the strike. The economic terms of a cap are notional (the loan balance the cap covers, usually the bridge loan amount), term (1–5 years; bridge caps are usually 2–3 years to match the loan term), strike (the SOFR threshold above which the cap pays), and the upfront premium (the price paid at purchase; non-recoverable).

The payoff at each monthly reset is straightforward:

Monthly Cap Payoff = max(0, SOFR_reset − Strike) × Notional ÷ 12

The cap pays only when SOFR resets above the strike. If SOFR is at or below the strike on the reset date, the cap pays zero for that period. The cap does not require the borrower to do anything; the cap provider (the bank counterparty) pays automatically into the borrower's account at each reset. The Adventures in CRE glossary entry on rate caps walks the mechanics with a Meadow Lane Capital worked example that mirrors the institutional pattern.

Three properties make caps the dominant bridge-loan hedge. (1) No MTM exposure to the borrower. The cap is paid for at origination; the value of the cap can decline to zero (if SOFR falls and stays below the strike), but the borrower never owes anything beyond the upfront premium. Bridge sponsors who carry floating-rate exposure on illiquid assets cannot tolerate the MTM volatility of swaps; the cap eliminates that risk by structure. (2) Lender-friendly. Bridge lenders require caps because the cap eliminates the rate-spike scenario that would compress the debt-yield cushion below underwriting minimums. A cap at SOFR + 100 bps over the going-in coupon pins the worst-case debt service the lender has to underwrite. (3) Term matches the loan term. Bridge loans are 2–3 year initial term with 12-month extensions; cap terms are 2–3 years with explicit renewal pricing for the extension period. The instrument fits the loan structure.

Cap pricing depends on three factors. The SOFR forward curve drives the expected payoff profile — a steep upward-sloping forward curve raises the expected payoff and the premium. Implied volatility raises the option value; higher vol means a wider distribution of possible SOFR outcomes and a higher cap price. Counterparty credit — the bank's cost of capital and credit risk — adds the spread on top. Per Pensford and Chatham Financial (now cf.com) market commentary, indicative Q1 2026 cap pricing on $50M notional, 3-year term:

Indicative Q1 2026 SOFR cap pricing, $50M notional, 3-year term. Pricing varies materially by SOFR forward curve assumption, implied volatility, and counterparty bid. Reported ranges reflect dealer indications, not executed trades; actual pricing is requested as a competitive bid across 3–5 counterparties at purchase.

Counterparty considerations matter on caps even though MTM exposure is zero. The cap is only as good as the counterparty that wrote it. In 2008, several CRE rate caps written by Lehman Brothers and Bear Stearns went unpaid when the counterparties failed. The current institutional discipline limits counterparty concentration: large CRE sponsors split cap purchases across multiple Wall Street counterparties (Goldman, JPM, Morgan Stanley, BofA) and require the counterparty to maintain a minimum credit rating (typically A− or better) for the term of the cap. The cap-provider rating downgrade is the institutional risk that practitioners price into the counterparty selection.

Interest Rate Swaps in Detail

An interest rate swap is a bilateral contract between two counterparties to exchange cash flows on a notional principal over a defined term. In the standard CRE pattern, the borrower pays a fixed rate to the counterparty bank and receives a floating SOFR rate from the bank, with the bank's floating receipt offsetting the borrower's floating-rate liability on the underlying loan. The economic effect: the borrower has converted a floating-rate loan into a synthetic fixed-rate loan.

The contract has no upfront cost at origination because the swap is priced at par — the present value of the fixed-leg payments equals the present value of the expected floating-leg receipts under the SOFR forward curve. After origination, as rates move, the swap has a positive or negative mark-to-market value. If rates rise, the swap is in-the-money for the borrower (the borrower locked in a lower fixed rate); if rates fall, the swap is out-of-the-money (the borrower pays a fixed rate above market). The swap can be unwound at any time at the prevailing MTM, with the borrower receiving or paying the cash settlement accordingly — this is "swap breakage."

Swap mechanics live inside the ISDA Master Agreement framework, the institutional standard for derivatives contracts globally. Per ISDA, the 2002 Master Agreement is the controlling document; each swap is a confirmation under the Master, with the deal-specific economic terms in the Schedule and the collateral mechanics in the Credit Support Annex (CSA). Three documents, three functions:

• The Master Agreement. The 2002 version is the current institutional standard (the 1992 version remains in use for some legacy trades). It governs the overall counterparty relationship: events of default, termination events, payment netting, set-off, governing law, jurisdiction. The Master is signed once between two counterparties and covers every derivative trade between them thereafter.

• The Schedule. Bilateral elections under the Master that customize specific provisions for the counterparty pair: which threshold amounts trigger termination, which jurisdiction's law applies, whether automatic early termination is in effect, which credit-support documents are incorporated. The Schedule is the document where the credit and legal teams of the two counterparties negotiate the deal-specific risk allocation.

• The Credit Support Annex (CSA). The collateral document. The CSA defines what collateral each counterparty must post when its MTM exposure to the other exceeds a threshold. For CRE sponsor counterparties, the CSA typically has a sponsor threshold of zero (the sponsor posts collateral on any MTM move against it) and a bank threshold tied to the bank's credit rating. The CSA mechanics are operationally consequential — daily MTM marks, weekly or monthly collateral calls, and collateral disputes that go to the ISDA dispute resolution framework. Practitioners read every line.

The legal infrastructure matters because swaps are bilateral contracts with bilateral risk. Both counterparties have MTM exposure to each other; both can default. The 2008 Lehman default was the institutional inflection point that hardened the CSA framework: collateral thresholds tightened, eligible collateral types narrowed (cash and Treasuries dominate; other collateral has haircuts), and counterparty netting became standard practice. The Cadwalader CRE finance group's Real Estate Finance News & Views publication is one of the better practitioner-grade references for the post-2008 ISDA evolution in the CRE-specific context.

Swap pricing in Q1 2026 follows the SOFR forward curve plus the counterparty's credit-and-funding spread. Per Pensford forward curve and Chatham/cf.com market commentary, indicative 5-year SOFR-vs-fixed swap rates in Q1 2026 sit at roughly 4.10–4.30% fixed leg, with 7-year at 4.20–4.50% and 10-year at 4.30–4.60%. These rates are par at execution; thereafter, the borrower's MTM moves with the curve. On a $100M 5-year swap at 4.20% fixed, a 50 bps parallel curve shift produces approximately $2.0–2.5M of MTM movement — the magnitude that drives CSA collateral calls.

Collars and Swaptions

A collar combines a long cap with a short floor: the borrower buys a cap at one strike and simultaneously sells a floor at a lower strike. The premium received from the sold floor offsets the premium paid for the cap, reducing the upfront cost of the hedge. The trade-off: if SOFR falls below the floor strike, the borrower owes the difference on the short-floor leg — the borrower has given up the rate-decline benefit in exchange for cheaper rate-spike protection. A "zero-cost collar" or "costless collar" is a collar where the cap and floor strikes are calibrated such that the two premiums offset exactly.

Collars fit at rate-cycle inflection points where the borrower views rate-decline scenarios as low probability but is unwilling to pay full cap premium. The 2024–2026 environment, with SOFR at 4.40–5.30% and Fed signaling a potential easing cycle, is a textbook collar window: a borrower who believes SOFR will stay in a 4.0–5.5% range can sell a 4.0% floor against a 5.5% cap and reduce the upfront premium materially. The borrower forgoes the benefit if SOFR falls below 4.0% but gains rate-spike protection above 5.5% at lower net cost. Per Derivative Logic and Defease With Ease comparator content, collars represent perhaps 5–10% of CRE rate-hedge volume — not dominant, but a meaningful tool for sophisticated borrowers.

A swaption is an option to enter a swap at a future date and pre-agreed rate. Two flavors: a payer swaption (the option to pay fixed and receive floating, exercised if rates rise above the strike) and a receiver swaption (the option to receive fixed and pay floating, exercised if rates fall below the strike). For CRE, the dominant use case is forward hedging at refinance maturity: a sponsor with a 2027 loan maturity can buy a 2026 payer swaption struck at the current 5-year swap rate, locking in the option to fix the refinance at a known rate without committing to do so. If rates fall by 2027, the swaption expires worthless and the sponsor refinances at the lower market rate. If rates rise, the swaption is exercised and the sponsor has locked in the lower rate from a year earlier.

Swaptions are situational because the premium can be large (forward-volatility-sensitive) and the use case is specific. The institutional pattern: large CRE platforms (REITs, pension funds, life-co lenders) use swaptions to manage portfolio-level refinance risk; smaller sponsors rarely encounter them. Per Chatham/cf.com advisory work, swaption volume in CRE is perhaps 2–3% of total hedge notional — meaningful at the platform level, niche at the deal level.

Hedge Accounting Under ASC 815

Every CRE hedge has an accounting consequence under FASB Accounting Standards Codification Topic 815 (Derivatives and Hedging), and the accounting election is consequential. ASC 815 distinguishes between three treatments based on whether the hedge is "designated" and whether it meets the hedge effectiveness test:

• Cash flow hedge (designated, effective). The derivative offsets variability in expected future cash flows. The effective portion of the derivative's change in fair value flows through Other Comprehensive Income (OCI), accumulates in AOCI on the balance sheet, and is reclassified to earnings when the hedged transaction affects earnings (i.e., when the floating-rate interest is paid). The ineffective portion hits P&L immediately. This is the most common designation for a SOFR cap or a pay-fixed/receive-floating swap on a CRE loan.

• Fair value hedge (designated, effective). The derivative offsets variability in the fair value of an existing asset or liability. Both the derivative MTM and the hedged item's offsetting fair value change flow through P&L. Less common in CRE; more common in corporate-finance hedging of fixed-rate debt obligations.

• Undesignated (or designation failed). The derivative's full MTM hits P&L every period as fair-value gain or loss. No OCI deferral. This is the default treatment if the borrower does not designate the hedge at inception or if the hedge fails the effectiveness test. It produces substantial earnings volatility on derivatives with large notional amounts — the income-statement impact that catches sponsors who treated the hedge as a pure economic decision without thinking through the accounting.

Hedge effectiveness must be assessed both at inception (prospective test) and on an ongoing basis (retrospective test). The traditional benchmark is the 80–125% rule of thumb: the derivative's change in fair value must offset 80–125% of the hedged item's offsetting fair value change to qualify as "highly effective." FASB's 2017 amendments (ASU 2017-12) simplified some aspects of the test and added a presumption of effectiveness for certain structures, but the underlying discipline remains: document the hedging relationship, test effectiveness, document the results.

For private companies, the FASB's Simplified Hedge Accounting Approach under ASU 2014-03 (Private Company Council) allows certain swap structures to be accounted for at "settlement value" rather than fair value, with a presumption of effectiveness. The approach applies to a narrow set of structures (pay-fixed-receive-floating swaps on existing variable-rate borrowings, matching maturities and notionals) but eliminates the operational burden of full ASC 815 hedge documentation for qualifying transactions. Smaller CRE sponsors and private real estate funds use this election routinely. Big Four accounting guides (Deloitte, KPMG, EY, PwC) publish detailed roadmaps; cite the firm's guide rather than fabricating URLs that route through paywalled tax-research portals.

Bridge vs Perm Hedging Strategy

The institutional pattern for CRE rate hedging maps directly to the loan structure and the lender's requirements. The split between caps and swaps is not arbitrary; it follows from the credit logic on each side of the loan.

The institutional bridge-vs-perm hedging convention. The split follows from the lender's credit logic on each loan structure — it is structural, not stylistic.

A worked example brings the split into focus. A $50M bridge loan in May 2026 at SOFR + 350 bps, 24-month initial term plus 12-month extension. Going-in coupon at 4.55% SOFR: 8.05%. The lender requires a 3-year SOFR cap at 5.00% strike on the full $50M notional. Cap premium at Q1 2026 pricing: roughly $1.25M (2.5% of notional). The all-in carrying cost: 8.05% headline coupon + amortized cap premium of about 50 bps over 24 months + amortized origination of about 38 bps over 24 months = roughly 8.93% all-in. If SOFR moves to 6.00% at month 18, the cap pays (6.00% − 5.00%) × $50M = $500K/year ≈ $42K/month of cap payoff that offsets the higher floating-rate interest. The sponsor's net effective rate caps at 5.00% + 3.50% spread = 8.50% even if SOFR continues to rise.

Now contrast a $100M bank permanent term loan, 7-year term, floating at SOFR + 200 bps. The bank requires the loan to be effectively fixed-rate at the bank's balance-sheet level. The borrower executes a 7-year SOFR-vs-fixed swap at the par fixed rate of approximately 4.30% in Q1 2026. The borrower's all-in cost becomes 4.30% (fixed leg of swap) + 2.00% (loan spread) = 6.30% effectively fixed for the full 7 years. The borrower pays the bank SOFR + 200 bps on the loan; the borrower pays/receives the swap net of SOFR; the two SOFR legs offset, leaving the borrower with a fixed 6.30% net coupon and the bank with a fixed economic return on its balance sheet asset.

The bridge cap and the bank swap are not interchangeable instruments. A bridge sponsor cannot use a swap because the MTM volatility would destroy the project-level economics on an illiquid asset undergoing a capex program; a bank-perm borrower would not use a cap because the upfront premium on a 7-year cap is prohibitive (often 4–7% of notional) and the borrower wants full rate certainty, not partial protection. The instrument follows the structure.

Q1 2026 Cap Pricing Reality

Cap pricing in Q1 2026 reflects a SOFR forward curve that has flattened from the steep upward slope of 2023–2024. As of mid-2026, SOFR sits at approximately 4.40–4.55%, with the 1-year forward at roughly 4.00% and the 3-year forward at approximately 3.70%. Implied volatility on SOFR caplets remains elevated versus the 2019–2021 baseline, reflecting market uncertainty about Fed policy path. Counterparty credit spreads have tightened modestly from the 2023 wides.

The practical pricing pattern that practitioners encounter in 2026:

• 1-year caps are cheap (typically 30–100 bps of notional) but rarely useful for CRE because the term is shorter than the loan. Occasionally used as a renewal bridge while a longer cap is negotiated.

• 2-year caps dominate the bridge market when the bridge loan has a 24-month initial term without a required extension cap. Pricing on $50M notional at 5.00% strike: 1.0–1.5% of notional ($500K–750K).

• 3-year caps are the institutional baseline for bridge loans with a 24-month initial term plus 12-month extension covered. Pricing on $50M notional at 5.00% strike: 2.0–3.0% of notional ($1.0M–$1.5M).

• 5-year caps are rare in CRE because the cost is prohibitive (4–7% of notional at typical strikes) and most CRE loans either roll into permanent debt at year 3 or refinance into a new bridge cap. Used occasionally on construction-to-perm structures where the construction phase plus stabilization extends beyond 3 years.

The institutional pre-hedging discipline is to start the cap-purchase conversation 90–120 days before loan closing, request competitive bids from 3–5 counterparties, and execute at the tightest bid within a defined trading window. The Derivative Logic cap-purchase guide recommends at least a week of lead time; Chatham/cf.com's institutional advisory practice runs longer windows for larger notionals. The competitive-bid discipline typically saves 10–30 bps of premium on the executed price — on a $50M, 3-year cap, that is $50K–150K of savings on a $1.0–1.5M purchase.

The 2024–2026 Cap Renewal Story

The most consequential CRE-hedging story of the current cycle is the cap-renewal cost spiral. 2021-vintage caps purchased at the trough of pricing — SOFR at 0.05%, strikes set at 1.5–2.0% (then out-of-the-money by 1.5 percentage points), 3-year terms — cost 25–50 bps of notional. A $50M bridge loan in 2021 purchased a 3-year cap for $125–250K. When that cap expired in 2024 and the sponsor needed to extend the bridge into a renewal cap at current market — SOFR at 5.30%, strikes set at 5.50% to maintain debt-yield underwriting — the renewal premium was 1.5–2.5% of notional. Same $50M notional, same 3-year term, same structural cap. New cost: $750K–$1.25M. 5–10x the original premium, often more than the sponsor's entire annual capex budget for the property.

The math illustrates the institutional impact. A 2021-vintage $50M bridge loan, 3-year cap at 2.0% strike, bought for $200K (40 bps of notional). The cap is structured to cover the initial 24-month bridge term plus a 12-month extension. SOFR moved from 0.05% to 5.30% between 2022 and 2023; the cap was deeply in-the-money and paid out approximately $1.5–2.0M over the cap term. Premium $200K, cap payoff $1.5–2.0M — the cap was the best hedge in CRE history at that vintage. Then, in 2024, the cap expired. The sponsor needed an extension to give the asset another 12–24 months to stabilize. The renewal cap at 5.50% strike, 24-month term: $750K. The sponsor's capex budget for the year was $600K. The cap renewal cost more than the asset's planned capex.

Per KBRA CRE CLO research cited in the bridge-loans article, this renewal-cost arithmetic is one of the primary drivers behind the elevated CRE CLO delinquency rate on 2021-vintage loans. Sponsors who could not afford the renewal cap defaulted into workout. Sponsors who could afford the cap but could not refinance into permanent debt extended the bridge at higher cost and accepted thinner equity returns. Sponsors who modeled the renewal cost into the original deal economics (rare in 2021, standard in 2026) survived intact. Trepp's CRE CLO surveillance and KBRA's structured-finance ratings commentary document the cohort impact.

The institutional pre-renewal discipline in 2026 is now hardened. Three rules that emerged from the 2024–2025 distress cycle:

• Start the renewal conversation 12–18 months before expiry. Caps are illiquid at the deal level; the counterparty bid quality varies; the price discovery process takes weeks. Starting at 90 days out forces a price-taker position; starting at 12–18 months out allows competitive bidding, optional structures (forward-starting caps, layered caps, partial-notional renewals), and coordination with the lender on the strike requirement.

• Model the renewal cost into the original deal economics. The initial cap covers the initial loan term. If the loan has a 12-month extension option, the renewal cap is a known future cost that should be in the IRR model from day one. The institutional pattern in 2026 is to amortize the expected renewal cap cost over the full bridge-plus-extension period; sponsors who ignored this in 2021 are the ones in distress now.

• Consider forward-starting caps at origination. A forward-starting cap is a cap that begins at a future date and runs for a specified term — effectively locking in renewal cap pricing today against a known future need. The instrument is more expensive in absolute dollars (paying upfront for a cap that will not start for 24 months) but eliminates the renewal-pricing uncertainty. Larger institutional sponsors use forward-starting caps routinely; smaller sponsors accept the spot-renewal risk and price it into the IRR.

How to Model It

A useful CRE rate-hedge model has five elements: the SOFR forecast curve, the cap or swap structure, the hedge payoff cash flows, the all-in coupon math, and the hedge-accounting flow-through. Most Excel debt tabs handle the headline coupon and miss the hedge cash flows entirely.

• 1. Build the SOFR forecast curve. Pull the current SOFR forward curve from Pensford or a Bloomberg ICVS terminal. Model SOFR at each monthly reset across the loan term. Do not use a point estimate — the 2021-vintage failures came from sponsors who modeled SOFR at 0.05% for the entire bridge term.

• 2. Structure the hedge. For a cap: notional, strike, term, upfront premium. For a swap: notional, fixed leg, floating leg (SOFR + spread), term, CSA collateral parameters. Model both as explicit rows in the debt tab, not as inline formulas inside the interest calculation.

• 3. Compute the hedge payoff cash flows. For each monthly reset: cap payoff is max(0, SOFR − strike) × notional ÷ 12; swap net cash flow is (SOFR − fixed) × notional ÷ 12. Sum the hedge payoffs across the term; verify the all-in effective coupon equals the hedge-adjusted interest cost.

• 4. Layer in the all-in coupon math. Headline rate + amortized origination + amortized cap premium (or swap MTM gain/loss) + exit fee. The all-in is what an institutional IC memo should quote, not the headline. The DSCR sizing test runs on the headline; the deal economics live on the all-in.

• 5. Apply the hedge-accounting flow-through. Designate cash-flow or fair-value hedge; flow the effective portion through OCI/AOCI; flow the ineffective portion or undesignated MTM through P&L. For fund-level reporting, this is the line item that drives quarterly volatility and the LP-question that comes up at annual meetings.

The Apers Marketplace pocket models below run this workflow as a single-sheet pattern. AQ-141 (opportunistic with bridge) handles the bridge-cap mechanics natively, with SOFR forward-curve sensitivity, cap payoff cash flows across strike scenarios, and the all-in coupon impact of cap renewal at extension. DV-003 (construction-to-perm) handles the construction-cap and conversion-swap-lock transition. AQ-110 (multifamily acquisition) handles the bank-perm swap structure with the fixed-leg sensitivity.

Common Mistakes

Seven errors that show up repeatedly on CRE rate-hedge structuring — each one of them has caused institutional sponsors material harm in the 2022–2026 cycle:

• Buying the cap at the wrong strike. Too high (e.g., 6.50% on a base case of 4.40%): wasted premium — the cap rarely pays. Too low (e.g., 3.50% on a base case of 4.40%): the cap starts deeply in-the-money and the premium is dominated by intrinsic value, making the cap prohibitively expensive. The institutional sweet spot is 50–100 bps above the base-case SOFR path, where the cap is slightly out-of-the-money but still provides meaningful payoff in the rate-spike scenario.

• Confusing a cap with a floor. A cap pays the holder when rates rise above the strike; a floor pays the holder when rates fall below the strike. A collar combines them. Sponsors who write the wrong structure on the term sheet end up with the opposite economic exposure — a cap holder who thought they had bought a floor and now is short rate-decline protection.

• Treating swap MTM as the same thing as swap breakage. Related, not identical. The MTM is the daily mark of the swap's value — what the swap would be worth if unwound today. Swap breakage is the cash settlement at unwind, which is the MTM plus the dealer's bid-offer spread plus any documented breakage fees in the swap confirmation. The dealer's bid-offer spread on a $100M swap can be 1–5 bps of notional; on a 7-year swap, that is $700K–$3.5M of cost on top of the headline MTM.

• Failing to designate the hedge under ASC 815 at inception. The accounting designation is a day-one decision. A hedge executed without designation cannot retroactively claim cash-flow hedge accounting; the full MTM hits P&L every period. Coordinate the designation with treasury and the auditor before the trade.

• Not modeling the cap renewal cost. The most common 2021-vintage mistake. The initial cap covers the initial loan term. If the loan has a 12-month extension option, the renewal cap is a known future cost. Sponsors who modeled only the initial premium were surprised by the 5–10x renewal cost. The 2026 standard is to amortize the expected renewal cost into the IRR from day one.

• Ignoring counterparty risk on the cap or swap counterparty. The cap is only as good as the counterparty that wrote it. A cap from a counterparty that downgrades below A− mid-term is a deteriorating hedge. The institutional pattern is to limit counterparty concentration, require minimum counterparty ratings, and include rating-trigger replacement provisions in the swap documentation.

• Using a swap where a cap is the right instrument (and vice versa). The most strategic mistake. Bridge sponsors who use swaps inherit MTM volatility on an illiquid asset; bank-perm borrowers who use caps overpay for partial protection when full hedging is the goal. The instrument must match the loan structure and the borrower's MTM appetite.
