New hotel at dusk.

Summary

No federal banking regulator, SBA rule or USDA rule tells a lender how hard to stress a loan. The binding text requires sensitivity analysis and reasonable, supported projections. The familiar numbers, a 300 basis point shock or breakeven occupancy below 70 percent, are either borrowed from bank-level interest rate risk guidance or are market convention. The size of the shock is the lender's choice, which is exactly why it should be calibrated and written down.

The historical record supplies the calibration. Hotel RevPAR fell 16.7 percent in 2009 and 47.5 percent in 2020. Prime rose 525 basis points between March 2022 and July 2023. The median new senior housing community opened from 2022 to 2024 was 74 percent occupied after two years. About three in four construction projects run late, by a median of 20 to 40 percent of planned duration.

On our case, a new 80-room hotel financed through a 504 at 1.31x base coverage, each shock alone is survivable and the combination is not. A 2009-style RevPAR decline takes coverage to 0.85x. A repeat of the 2022–2023 rate cycle on the floating first lien takes it to 0.99x. A six-month delay with a slower ramp raises the liquidity the borrower needs from $51,000 to about $750,000. Occupancy, rate and interest shocks together produce 0.80x.

No rule tells a lender how hard to stress a loan. That is why the shock should be calibrated to the record and written down, and why breakeven occupancy, rate shock and ramp-up delay belong in every projection-based file.

Ask a credit officer how hard to stress a floating-rate loan and the answer is usually 300 basis points, often followed by "regulators require it." The number is defensible. The reason is not.

The 300 basis point figure comes from the January 2010 interagency advisory on interest rate risk. It told banks that parallel shocks of plus and minus 200 basis points "may not be sufficient," and offered 300 and 400 basis points as examples of larger moves to test. The FDIC repeated the point in 2012 for a low-rate environment. Both documents address a bank's own balance sheet, not a borrower's debt service coverage, and both are guidance written in "should" and "e.g." No loan-level rule we found, from the banking agencies, SBA or USDA, names a shock size, a breakeven ceiling or a delay period.

That absence is not permission to skip the test. The Interagency Guidelines for Real Estate Lending Policies, which banks' written real estate lending policies must take into account, expect "requirements for feasibility studies and sensitivity and risk analyses." What the guidelines leave open is the magnitude. In most credit memos we have read, and a fair number we have written, the magnitude is chosen by habit. It should be chosen by history.

This piece sets out what the rules actually require. It then runs one projection-based loan, a new 80-room hotel, through the three stresses that matter most for operating real estate: breakeven occupancy, rate shock and ramp-up delay. For each, we calibrate the shock to the historical record and show the arithmetic. Our companion piece on what to do when coverage fails covers the structural fixes. This one is about finding out, before closing, whether you will need them.

What the rules actually require

The rules come in three tiers. The difference between them is the difference between an exam finding and a judgment call.

Tier	Source	What it says about stress	Numbers it sets
Binding	Real estate lending standards, 12 CFR 34 subpart D and agency equivalents, and the Interagency Guidelines	Written policy should require feasibility studies and sensitivity of income to interest rates, vacancy and operating expenses	None
Binding	13 CFR 120.214, SBA 7(a) variable rates	Caps the lender's spread over the base rate; the base rate itself is uncapped	Spread caps of 3.0 to 6.5 points
Binding	7 CFR 5001.303 to 5001.306, USDA OneRD	Projections through two years of stable operations, with assumptions listed; independent feasibility study for B&I loans over $1 million to new businesses; Community Facilities projections must consider rate adjustments	90 percent occupancy cap for CF care facilities
Binding product rule	Fannie Mae and Freddie Mac multifamily	Floating-rate loans sized at a capped or maximum rate	1.05x at Fannie Mae's Maximum Note Rate; 1.15x at Freddie Mac's capped rate
Guidance	OCC Bulletin 2012-33; 2006 CRE concentration guidance; 2023 CRE workout policy statement; OCC CRE Lending booklet	Stress or sensitivity analysis expected; method left to the bank; realistic projections; no bright lines	Two-year horizon; base case plus at least one adverse scenario
Convention	Lender policy and practitioner literature	Shock sizes, breakeven thresholds, delay and reserve months	+100 to +300 bp; breakeven 60 to 85 percent; 4 to 12 months of delay

OCC Bulletin 2012-33, issued October 18, 2012 for banks with $10 billion or less in assets, is the most specific supervisory text. It treats stress testing or sensitivity analysis of loan portfolios, at least annually, as "a key part of sound risk management." It asks for a base case and at least one adverse scenario over a horizon of at least two years. It also states plainly that the OCC "does not endorse a particular stress testing method." Its definition of reverse stress testing, assuming an adverse outcome and deducing the events that would produce it, was written for capital planning but works just as well for a single loan. The OCC's Commercial Real Estate Lending booklet asks that income factors be considered "under both normal and stressed conditions." The 2023 interagency policy statement on CRE workouts asks for realistic projections and states that it "does not set bright lines."

SBA's text is thinner than most people assume. The SOP requires detailed projections with supporting assumptions for start-ups and construction projects, showing 1.15x within two years. For 504 loans, the CDC must support the reasonableness and attainability of the assumptions, and a year-one shortfall must be covered by demonstrated liquidity. Under SOP 50 10 8.1, a 7(a) change of ownership may not rely on projections at all. In the sections we have reviewed, we found no SBA requirement to stress or sensitize projections. USDA is more explicit: the feasibility study components it adopts list sensitivity analysis by name.

Three commonly repeated claims follow from this, and each deserves an audit.

"Regulators require a 300 basis point shock." Partially true, and misapplied. The figure is real, but it is an example in bank interest rate risk guidance, not a loan underwriting rule.

"Breakeven occupancy must be below 70 percent." False as a rule. No banking, SBA, USDA or agency document we reviewed sets a breakeven ceiling. Published conventions range from about 60 percent for hotels and self storage to 85 percent for multifamily. A 70 percent ceiling may be one lender's policy. It is not a standard.

"SBA requires stress testing of projections." Unsupported by the text we could verify. SBA requires supported projections, and in acquisitions it now declines to rely on them. It does not prescribe a stress test. Lenders who run one do so because it is good credit practice, which is the better reason.

The case: a new 80-room hotel

The case is illustrative, but built on the kind of file we see most often in SBA hospitality lending: a new limited-service hotel with no operating history, financed on projections.

The hotel has 80 rooms and underwrites to a stabilized 70 percent occupancy at a $145 average daily rate, with other revenue at 3 percent of rooms revenue. Stabilized total revenue is $3,052,714. Variable costs, including franchise fees, commissions, housekeeping and a 4 percent FF&E reserve, run at 39 percent of revenue. Fixed operating costs, including property tax, insurance, base payroll and management, are $950,000. Stabilized NOI is $912,156.

Project cost is $10,000,000. Because the borrower is a new business acquiring a special purpose property, the 504 contribution is 20 percent. The stack is a $5,000,000 bank first lien, a $3,000,000 CDC loan and $2,000,000 of equity. The bank loan floats at 7.50 percent, Prime plus 0.50 percent, on 25-year amortization. The CDC loan is fixed at the October 2026 effective rate of 6.97 percent for 25 years. Annual debt service is $697,147: $443,395 on the bank loan and $253,752 on the CDC loan.

Base-case coverage is 1.31x. It clears SBA's 1.15x projection floor and most bank policies. Everything that follows asks how much of that cushion survives contact with the historical record.

Breakeven occupancy: a distance, not a threshold

The textbook formula divides operating expenses plus debt service by potential gross income. At breakeven, coverage is exactly 1.00x. For an apartment building, where most costs are fixed, the formula is close enough. For a hotel it is not, because a third or more of the cost base moves with occupancy.

The correct version solves for the occupancy at which revenue, less the costs that vary with it, just covers fixed costs and debt service. For our hotel, potential revenue at 100 percent occupancy is $4,361,020, and 61 cents of each revenue dollar survives variable costs. Breakeven occupancy is therefore ($950,000 + $697,147) ÷ ($4,361,020 × 0.61), or 61.9 percent. The textbook formula, holding expenses at their 70 percent level, gives 65.1 percent. Here the textbook answer is conservative, but it is wrong in a way that matters: it hides which costs the operator can actually shed.

A breakeven figure means little on its own. What matters is its distance from the underwritten case, and from the market. Our hotel has 8.1 points of occupancy cushion, and its breakeven sits almost exactly at the national average: U.S. hotel occupancy was 62.3 percent in 2025, still below the 66.1 percent of 2019. Put differently, the projection assumes the hotel will beat the national average by nearly eight points, and the loan pays only as long as it does. That is the sentence a credit committee needs, and no threshold supplies it.

Breakeven occupancy also assumes the room rate holds. In a downturn it does not. U.S. hotel ADR fell by roughly 9 percent in 2009 and by 21.3 percent in 2020. Rerun our breakeven with ADR 9 percent lower and it rises from 61.9 to 68.0 percent, leaving a cushion of two points. For hotels the honest measure is breakeven RevPAR, and the honest stress moves occupancy and rate together. At 70 percent occupancy, our hotel breaks even at an ADR of $128, a decline of 11.5 percent.

Published breakeven conventions vary by asset class and by source, and none has a regulatory basis.

Asset class	Breakeven commonly cited	Basis
Multifamily	62 to 85 percent	Practitioner and lender sources
Hotels	60 to 65 percent	analytics.loan stabilized occupancy benchmarks
Self storage	60 to 72 percent	Practitioner sources
Senior housing	No verified convention	USDA caps CF care-facility projections at 90 percent occupancy
RV parks and campgrounds	No verified convention	Seasonality reserves in CMBS loans; one financed RV portfolio was 49.6 percent occupied in February 2025

The RV example is the clearest proof that a single threshold cannot work. A seasonal park that is half empty in February can be a performing loan, because the lender underwrites the trailing twelve months and holds a seasonality reserve. A 70 percent rule would have declined it.

Calibrating the occupancy shock

The size of an occupancy or revenue shock should come from what the asset class has actually done, and the record differs sharply by class.

Asset class	Global financial crisis	COVID	Time to recover
Hotels, RevPAR	−16.7 percent in 2009	−47.5 percent in 2020	About 4 years after 2009; about 3 years in nominal RevPAR after 2020, with occupancy still below 2019 in 2025
Senior housing, occupancy	About −3 points, to 86.9 percent in Q1 2010	−9.3 points, from 87.1 to 77.8 percent, by June 2021	About 5 years after COVID
Multifamily	−7.9 percent effective rent; occupancy from 96 to 92 percent	Rents roughly flat in 2020, then +14.4 percent in 2021	About 7 quarters after the GFC
Self storage	Same-store revenue −3.2 percent in 2009	Occupancy rose to records; street rates later fell 17.7 percent year over year by October 2023	Post-COVID correction still working through
Small business revenue	Sales trends at record lows in March 2009	Roughly −40 to −50 percent in April 2020	Highly sector-dependent

Two lessons follow. First, a recession case and a severe case are different things. For a hotel, a 17 percent RevPAR decline is the recession case, and 50 percent for twelve months is the severe case. Second, some assets are not counter-cyclical so much as differently cyclical. Self storage and RV parks gained through COVID and then corrected hard; RV shipments fell 48 percent from 2021 to 2023.

On our hotel, a 2009-style RevPAR decline of 17 percent takes coverage from 1.31x to 0.85x. Five points of occupancy at a constant rate take it to 1.12x, and ten points take it to 0.93x. A 9 percent ADR decline at the underwritten occupancy takes it to 1.07x. A 2020-style year leaves NOI of about $28,000, which no coverage ratio can absorb and only equity and reserves can.

Rate shock: stress the index, not the spread

SBA's rate rule is often misread as protection. Under 13 CFR 120.214(d), a 7(a) loan over $350,000 may carry no more than 3.0 percentage points over the base rate. The cap limits the lender's spread. It does not limit the base rate, so a Prime-based 7(a) loan carries the full movement of Prime for its whole life. The February 2026 notice that added SOFR and Treasury base rates kept the ceiling at Prime plus the allowed spread, and none of the base rates is capped.

The record shows what that means. Between March 17, 2022 and July 26, 2023, the Federal Reserve raised its target eleven times, for a total of 525 basis points. Prime rose from 3.25 to 8.50 percent and stayed there for about fourteen months. The 20-year 504 debenture rate rose from about 3.07 percent in January 2022 to a cycle peak of 7.18 percent in October 2023. Rates are rising again: the Fed raised its target on September 16, 2026, Prime is 7.00 percent, and the October 2026 504 rate of 6.97 percent is close to its 2023 peak.

Prime	Note rate	Annual debt service on $1,000,000, ten years	Coverage if underwritten at 1.25x in early 2022
3.25 percent, early 2022	6.00 percent	$133,225	1.25x
8.50 percent, July 2023 to September 2024	11.25 percent	$167,003	1.00x
7.00 percent, October 2026	9.75 percent	$156,924	1.06x

A 7(a) loan priced at Prime plus 2.75 percent and underwritten at 1.25x in early 2022 reached breakeven on the rate cycle alone, with no change in its business.

The only codified stressed sizing we found sits in the multifamily agency programs. Fannie Mae sizes Structured ARM loans at a Maximum Note Rate, the minimum cap strike rate plus the margin, at a minimum of 1.05x. It requires a rate cap for the full loan term, and a cap reserve of at least 110 percent of replacement cost when the cap expires before maturity. Freddie Mac sizes floating-rate conventional loans at 1.15x on the maximum capped rate, and its transitional line of credit adds a 100 basis point stress rate when there is no cap. Both programs assume the index will move, and size the loan so that it can.

On our hotel, only the bank first lien floats; the CDC debenture is fixed. That matters.

Rate on the bank first lien	Total debt service	DSCR	Breakeven occupancy
7.50 percent, base	$697,147	1.31x	61.9 percent
9.50 percent, +200 bp	$777,970	1.17x	65.0 percent
10.50 percent, +300 bp	$820,261	1.11x	66.5 percent
12.75 percent, +525 bp	$919,183	0.99x	70.3 percent

A 200 basis point rise leaves the loan above SBA's projection floor. A repeat of the 2022–2023 cycle takes coverage below 1.00x and pushes breakeven occupancy above the underwritten case. Run in reverse, the bank rate at which coverage falls to 1.15x is 9.86 percent, 236 basis points above today's rate. The rate at which it reaches 1.00x is 12.59 percent.

The reverse figure is the more useful one. "The loan survives a 236 basis point move before it falls below SBA's floor" tells a credit committee more than "the loan passes a 200 basis point test," because the committee can compare the distance with what Prime has actually done. In the last cycle, Prime moved 525 basis points in sixteen months.

Ramp-up delay: the scenario lenders skip

Breakeven and rate shocks test a stabilized property. Most projection-based loans get into trouble before stabilization, because the property opens late, fills slowly, or both.

Delay is the norm. Peer-reviewed construction research, summarizing earlier studies, puts the share of projects that run late at about three in four, with a median delay of 20 to 40 percent of planned duration depending on the sector. In an Associated General Contractors survey published in August 2025, 78 percent of firms reported at least one delayed project in the prior twelve months. Delay also arrives with escalation. The Turner Building Cost Index rose about 26 percent from 2020 to 2025, and was up 5.15 percent year over year in the second quarter of 2026.

Lease-up is slower than projections. NIC MAP's analysis of more than 200 senior housing communities opened from 2022 to 2024 found the median community at 51 percent occupancy after four quarters, 65 percent after six and 74 percent after eight. Conventional underwriting assumes a three-year window. Certificate-of-need projections approved in New Jersey in 2023 and 2024 ranged from 60 to 95 percent occupancy at year two for broadly similar communities, and that spread alone is the argument for a delayed-ramp scenario. For hotels and multifamily we found no primary national data on months to stabilization. Lender sources cite 12 to 18 months for a new flagged limited-service hotel, which is a convention, not a measurement.

Supervisors expect the delay to be priced. The OCC's Commercial Real Estate Lending booklet says an interest reserve should fund interest through completion and lease-up, sized with the time needed to finish and lease the project in mind, and treats a repacked reserve as a red flag. The 2023 policy statement faulted a lender for not suspending an interest reserve during a development delay. The program rules supply the deadlines. Standard 7(a) projections must reach 1.15x within two years of the end of construction. A 504 that repays in year two but not in year one must show liquidity for the gap. USDA B&I allows up to three years before the first full principal and interest payment.

Here is our hotel under its base ramp, and under a six-month delay to opening followed by a slower ramp.

Year after opening	Base occupancy	Base DSCR	Delayed occupancy	Delayed DSCR
1	60 percent	0.93x	50 percent	0.55x
2	67 percent	1.19x	60 percent	0.93x
3	70 percent	1.31x	66 percent	1.16x
4	70 percent	1.31x	70 percent	1.31x

The base case meets SBA's two-year test, with a year-one shortfall of $51,000 that the borrower covers from liquidity. The delayed case does not reach 1.15x until year three. Its operating shortfall over the first two years is $368,000. The six months of delay add about $310,000 of carry on an $8,000,000 interim balance at 7.75 percent, and about $72,000 of escalation on the unbuilt half of a $7,000,000 hard cost budget. Carry and escalation alone exceed a 5 percent construction contingency of $350,000. In total the borrower needs about $750,000 of liquidity, roughly fifteen times the base case.

Nothing in that scenario is extreme. A six-month delay on a fourteen-month build is a 43 percent overrun, just above the median range and well inside the distribution. A 50 percent first-year occupancy is about where NIC's median senior housing community stood after four quarters.

Combined and reverse: the tests that inform a decision

Single-variable sensitivities show which input matters. They understate risk, because downturns move several inputs at once. In 2009, hotel occupancy and room rates fell together. In 2022 and 2023, rates rose while several sectors softened.

Our combined downside moves three inputs by amounts well inside the record: occupancy five points lower, ADR 9 percent lower, and the floating rate 200 basis points higher. None of the three is severe on its own. Together they take coverage to 0.80x and leave the hotel about $154,000 a year short of debt service.

Stress on the stabilized hotel	DSCR
Base case	1.31x
Rate +200 bp	1.17x
Occupancy −5 points	1.12x
Rate +300 bp	1.11x
ADR −9 percent	1.07x
Rate +525 bp, the 2022–2023 cycle	0.99x
Occupancy −10 points	0.93x
RevPAR −17 percent, the 2009 decline	0.85x
Combined: occupancy −5 points, ADR −9 percent, rate +200 bp	0.80x

Reverse tests answer the question a committee is really asking: how far can each input move before the loan stops paying? For our hotel, occupancy can fall 8.1 points. ADR can fall 11.5 percent. The floating rate can rise 509 basis points before coverage reaches 1.00x, or 236 basis points before it falls below 1.15x. And a six-month delay pushes the 1.15x milestone past SBA's two-year window. Each of those distances can be set beside what the market has actually done, which is the comparison no single threshold allows.

The default record shows why the joint shock is the test that matters. S&P Global Ratings, using Trepp data on more than 110,000 CMBS loans, found that loans whose coverage fell below 1.00x during the term defaulted at 27.2 percent, against 6.1 percent for loans that stayed above it. KBRA's 2025 study of 108,096 conduit loans puts the 2008 vintage at a 32.7 percent default rate, against 16.9 percent for the whole sample. SBA's own twelve-month purchase rates on 7(a) loans rose from 1.9 percent for fiscal 2007 to 7.3 percent for fiscal 2010, and on 504 loans from 0.8 to 6.3 percent.

Origination coverage protects a loan only if it covers the shock the loan will actually meet. A base case of 1.31x is a comfortable number. Whether it is a comfortable loan depends on the distance to 1.00x under the stresses the record says are plausible.

What we do differently

Because no rule sets the shocks, the methodology has to be stated. Ours is our methodology, not a regulatory requirement, and it runs as follows.

Calibrate every shock to the record for the asset class. For hotels, a recession case of RevPAR 17 percent lower and a severe case of 50 percent lower for twelve months. For senior housing, occupancy ten points lower with a four- to five-year recovery. For multifamily, rent 8 percent lower and occupancy four points lower. The source period sits beside each number.
Run single-variable sensitivities first. Rate +100, +200 and +300 basis points; occupancy −5 and −10 points; rent or ADR −10 percent; operating expenses +5 and +10 percent. These show which input drives the loan.
Run at least one named downside scenario. Several inputs moved together under a coherent narrative, as OCC Bulletin 2012-33 describes, over a horizon of at least two years past stabilization.
Report the reverse tests. Breakeven occupancy, breakeven rent or ADR, the breakeven index rate, and the months of delay that exhaust the interest reserve and the contingency. These are the numbers a committee can compare with history.
Stress the index on floating debt. For Prime-based SBA loans, the current index plus the contractual spread plus 200 to 300 basis points, with the 2022–2023 move of 525 basis points as the severe case. For floating multifamily, we mirror the agency mechanics: size at the capped rate and test cap expiry.
Treat projections according to the program. For a 7(a) change of ownership after October 1, 2026, projections are risk analysis only. For USDA files, a labeled sensitivity section, care-facility occupancy capped at 90 percent where 7 CFR 5001.304 applies, and note-rate adjustments modeled explicitly.

The point of an independent feasibility study is not a base case that clears 1.15x. Any spreadsheet can produce one. The point is to show the lender how far the base case can bend before it breaks, and what in the market would bend it.

Current as of November 3, 2026

This analysis reflects supervisory guidance and program rules in force on November 3, 2026. That includes SBA SOP 50 10 8.1 with Technical Policy Updates, effective October 1, 2026, and 7 CFR Part 5001 as published on eCFR. OCC Bulletin 2012-33 remains posted, although OCC Bulletin 2021-21 terminated its companion CRE stress test tool. OCC Bulletin 2026-29 issued a new lending booklet together with rescissions of older booklets. We cite the Commercial Real Estate Lending booklet, Version 2.0, and have not relied on any booklet whose current status we could not confirm.

SBA publishes its SOP as a Word document. Our description of SBA's projection requirements follows practitioner readings of that text, and our statement that SBA does not prescribe a stress test rests on the sections we reviewed rather than a full-text search. Freddie Mac's floating-rate coverage is taken from investor presentations, which have differed across versions. We use the June 30, 2026 figure of 1.15x.

Rates are as of late October 2026: Prime at 7.00 percent per the Federal Reserve's H.15 release, and the October 2026 504 effective rate at 6.97 percent. Historical market data come from STR, NIC MAP, RealPage, Public Storage filings, the Turner Building Cost Index and the other sources listed below. All case figures are illustrative and use the assumptions stated in the text. We refresh this piece when supervisory guidance or SBA credit standards change, and at least quarterly for rates.

Questions lenders and borrowers actually ask

Do regulators require a specific interest rate shock for commercial loans?

No. The 300 and 400 basis point figures come from bank interest rate risk guidance, framed as examples. Loan-level guidance, including OCC Bulletin 2012-33 and the 2023 CRE workout statement, expects stress or sensitivity analysis but sets no magnitude. Only the multifamily agency programs codify a stressed sizing rate.

What is a good breakeven occupancy?

There is no regulatory threshold. Published conventions run from about 60 percent for hotels and self storage to 85 percent for multifamily. What matters is the distance between breakeven and the underwritten occupancy, and between breakeven and the market. For hotels, breakeven should be computed with variable costs and tested with a lower room rate.

Does SBA require stress testing of projections?

Not in the SOP text we reviewed. SBA requires detailed projections with supporting assumptions, 1.15x within two years for start-ups and construction projects, and for 504 loans, liquidity to cover a year-one shortfall. Since October 1, 2026, a 7(a) change of ownership may not rely on projections at all.

How hard should a lender stress a Prime-based SBA 7(a) loan?

Our methodology uses the current Prime rate plus the contractual spread plus 200 to 300 basis points, with the 2022–2023 move of 525 basis points as the severe case. SBA caps the spread over Prime, not Prime itself, so the borrower carries the full movement of the index.

How long should a ramp-up delay scenario be?

Long enough to match the record. About three in four construction projects run late, by a median of 20 to 40 percent of planned duration, and the median new senior housing community was 74 percent occupied after two years. A six-month delay on a twelve- to eighteen-month build, followed by a slower lease-up, is a reasonable minimum.

Why run a reverse stress test?

Because it states the distance to failure in terms a committee can compare with history: how many points of occupancy, how many basis points of rate, or how many months of delay the loan can absorb before coverage reaches 1.00x.
