Why Regional and Community Banks Hold More Commercial Real Estate Risk
Regional and community banks carry more commercial real estate exposure because CRE is a much larger share of their assets and loans, and their loan books sit in narrower geographic footprints. CRE loans were nearly 30% of regional bank assets in one comparison, against approximately 6% at big banks. Regional and small banks together also hold a larger share of bank-held CRE mortgage debt than banks over $100 billion in assets. Concentration means a given loss rate consumes more of the institution’s equity, even when its reported CRE delinquency rate is lower than a large bank’s.
Share of assets, share of loans and the 30% versus 6% gap
Smaller banks look heavier in CRE on every ratio that divides by their own balance sheet. CRE loans were nearly 30% of regional bank assets in one comparison, against approximately 6% at big banks.
A second measure covers only nonfarm nonresidential CRE mortgages. It runs about one-fifth of total assets at institutions outside the largest supervisory categories. The category is narrower and the population is different, so the two figures do not conflict. They also cannot be swapped.
Share of loans is a third denominator, and it always runs higher than share of assets for the same balance because loans are only part of what a bank owns. Banks across one multistate region averaged 45% of total loans in CRE, which tied for third highest nationally. A veteran reading any concentration figure asks first which numerator and which denominator produced it.
A smaller lender holds a thin slice of the national pool of CRE risk. CRE is still a large slice of its own business. Small and medium-sized lenders also face concerns over credit quality and pay more for deposits, which narrows the room to absorb a bad stretch.
The consequence sits in the tail. Some institutions carry more concentrated exposure than the group average, and those are the ones that may take higher-than-average losses if CRE conditions weaken.
“Importantly, some banks may have more concentrated exposures to CRE mortgages than average and therefore may experience higher-than-average losses should CRE conditions weaken.”
Why a narrow footprint comes with the community bank model
Community and regional banks tend to carry higher CRE concentrations than large firms, and their real estate portfolios tend to be less geographically diversified.
The reason is built into the franchise. Local lenders may understand financing needs in rural areas that differ from those in large cities, and that local knowledge is part of why the country keeps so many small banks. A lender that underwrites the market it lives in tends to keep lending in it.
Local knowledge sharpens the read on each borrower and property. It does nothing to spread the portfolio across markets. Fifty well-documented loans in one county still share one local economy and one pool of buyers for the collateral.
The test a veteran applies is overlap among the loans. The count of loans tells little. A portfolio with many borrowers can behave like a single position when one local shock reaches most of the collateral at once.
The origination shift: where new CRE lending went
Exposure accumulates where lending flows. Regional and small-bank CRE originations rose seven-fold, from $38 billion at the start of the sample to a $262 billion peak. Over the same period, large-bank originations fell 40 percent.
Originations are a flow and outstanding loans are a stock. A year of heavy origination does not add the same dollars to the balance sheet, because repayments and payoffs reduce the opening balance. The divergence still shows new business moving toward one group of lenders.
The stock tells a matching story. Banks held half of the $6 trillion in outstanding CRE mortgage debt at the end of the latest period measured, and regional and small banks collectively held a larger share than banks over $100 billion in assets.
Those are comparisons between groups, and they say nothing about every member of either group. An individual institution’s position depends on its opening balance and on what it adds and removes over time.
Why lower delinquency and higher concentration coexist
Banks with less than $100 billion in assets had lower CRE delinquency rates than large banks in the latest supervisory data, yet a greater share of their total loans was exposed to CRE.
Property mix explains most of the gap. The lower delinquency at smaller banks mostly reflected lower holdings of large office loans, and unobserved extension or modification practices explained little of it. Large banks account for most large-city office lending, and nonperforming loans had risen mainly among them.
A portfolio delinquency rate is a weighted average. A lender with little of the weakest property type posts a better combined rate even if every loan type performs the same as a peer’s.
Two questions follow. The first asks which loans are late today. The second asks how much of the institution is exposed if CRE losses broaden. A smaller lender can look better on the first and carry more on the second.
Size brackets and capital treatment around the $100 billion line
Regulatory brackets decide which rules apply to a bank. A proposed capital framework applied to banking organizations with $100 billion or more in total assets, and smaller institutions would keep the existing standardized approach.
Risk weights convert a loan balance into risk-weighted assets, and capital is required against that total. A change in how CRE is weighted therefore reaches only the institutions inside the bracket where it applies.
Reforms to the Dodd-Frank framework widened the middle bracket of banks, so institutions near the $100 billion mark were no longer grouped with much larger firms.
The largest banks also face pressure from new capital requirements. That pressure and the heavy direct CRE holdings of small and mid-sized lenders sit in different brackets and arrive through different channels.
Worked example: the same 4 percent CRE loss at a 30 percent bank and a 6 percent bank
The setup is hypothetical and illustrative. Two banks each hold $2000000000 in assets and $200000000 in equity, which is an equity ratio of 10 percent. Fees are zero, the period is the same for both, losses reduce equity dollar for dollar, and taxes and recoveries are ignored. The CRE shares of 30 percent and 6 percent mirror the regional and big-bank gap in the published comparison.
Base case, the concentrated bank: CRE is 30 percent of assets. $2000000000 multiplied by 30 divided by 100 gives $600000000 of CRE loans. Against equity that is $600000000 divided by $200000000, or 3 times.
Alternative case, the diversified bank: CRE is 6 percent of assets. $2000000000 multiplied by 6 divided by 100 gives $120000000 of CRE loans, or 0.6 times equity.
Both banks take a 4 percent loss on CRE. The concentrated bank loses $600000000 multiplied by 4 divided by 100, which is $24000000. The diversified bank loses $120000000 multiplied by 4 divided by 100, which is $4800000. No other assets lose anything.
Remaining equity is $200000000 minus $24000000, or $176000000, for the concentrated bank. For the diversified bank it is $200000000 minus $4800000, or $195200000.
Measured against the same starting equity, the concentrated bank loses $24000000 divided by $200000000 multiplied by 100, or 12 percent of equity. The diversified bank loses $4800000 divided by $200000000 multiplied by 100, or 2.4 percent. The dollar loss is 5 times larger: $24000000 divided by $4800000.
A stress on the diversified bank asks what CRE loss rate would take the same $24000000. That rate is $24000000 divided by $120000000 multiplied by 100, which is 20 percent. Dividing 20 by 4 confirms it is 5 times the loss rate applied to the concentrated bank.
Identical credit performance produces very different outcomes because the exposure differs. Concentration and loan quality are separate variables, and this example holds quality constant to isolate concentration.
Mistakes that distort smaller-bank CRE comparisons
A denominator error mixes share of loans with share of assets. Assets include holdings beyond loans, so a CRE percentage computed against loans is larger than the same balance divided by assets. Setting a loans-based figure for one institution beside an assets-based figure for another overstates the gap.
A delinquency error reads a lower rate as proof of lower institutional exposure. Delinquency measures payment performance on the loans held, while concentration measures how much of the balance sheet those loans represent. Lower delinquency at smaller banks mostly reflected lower holdings of large office loans, so the rate reflects property mix.
A geographic error counts loans and calls the result diversification. Separate borrowers and separate collateral can sit in one market. Because smaller community banks tend to have less geographically diversified portfolios, a count of obligations leaves the relevant dimension unmeasured.
An averaging error assigns a group result to a single institution. Some banks hold more concentrated CRE exposure than the group average and may experience higher-than-average losses if CRE conditions weaken, so the balance sheet in question is the place to begin.
A flow-for-stock error treats origination volume as the change in outstanding exposure. Repayments reduce the opening balance, so origination growth shows where new business went and leaves the closing position unresolved.
Checklist questions for reading a bank’s CRE concentration
Which loans are in the numerator? A broad CRE measure and a nonfarm nonresidential mortgage measure describe different exposure sets.
Which balance is the denominator? Total loans and total assets answer different questions about the same CRE balance, and equity answers a third.
How does the institution compare with its own size group? An average can conceal a balance sheet with much heavier exposure.
How much of the book sits in one local market? Separate borrowers still share one economy when the collateral is close together.
How much of the delinquency comparison reflects large office loans? Property mix drives much of the gap between smaller and larger banks.
Do originations reconcile to the change in outstanding balances? Payoffs and repayments determine how much of a lending flow stays on the balance sheet.
What happens when one assumed loss rate hits each portfolio? A constant rate shows how much equity concentration alone consumes.
Which rules apply at the institution’s size? A bracket line decides whether a capital proposal reaches it at all.
