Why Banks Face Commercial Real Estate Refinancing Pressure

Maturing commercial real estate loans are hard to refinance when the replacement lender will advance less than the balance coming due. Higher rates cut the debt a property’s income can carry, and softer income and lower values cut what a lender will lend against the collateral. For a bank, each loan with a gap between principal due and available proceeds adds to portfolio exposure, even when the loan has paid on time until its last day.

Why a loan that pays on time can still fail the maturity test

Maturity risk is the risk that principal due at the end of a loan cannot be repaid from replacement debt, a sale or the borrower’s own cash. Commercial mortgages differ from homeowner loans in ways that concentrate this risk at one date. Their maturities are shorter, adjustable rates are more common, and principal may not be due until the end.

Where little or no principal has been paid down, the whole original balance meets a new lender’s underwriting on the maturity date. A record of every payment on time proves only that debt service was paid under the old loan terms.

Short-term borrowing minimizes cost but leaves the borrower exposed to rising interest expense, because the rate is not fixed for long. A fixed rate postpones that exposure to the refinance date, where it arrives all at once.

Refinancing commercial real estate loans remains a challenge for borrowers and for the banking industry when high interest rates, softening property values and emerging credit weakness show up together.

An extension moves the due date and leaves the balance where it was.

“Unlike a conventional mortgage for a homeowner, commercial mortgages typically have shorter maturities, are more likely to have adjustable rates and may not require principal payments until maturity.”

The two ceilings that cap replacement loan proceeds

A replacement lender sizes a loan against two separate tests, and the lower result controls. One test looks at income and the other looks at collateral value.

The income test uses the debt service coverage ratio, which is net operating income divided by annual debt service. If a lender requires a minimum ratio, the debt service it will allow equals net operating income divided by that ratio. For an interest-only loan, the maximum principal is that allowed debt service divided by the interest rate. An amortizing loan needs a payment calculation that also includes scheduled principal. Minimum ratios vary by lender and by property.

The collateral test uses the loan-to-value ratio, which is the loan amount divided by property value. A maximum ratio sets a second ceiling equal to value multiplied by that maximum. Value in turn comes from income: in a simple direct capitalization, value equals one year of net operating income divided by the capitalization rate, which is a one-year yield on price and says nothing about returns over a hold.

Rising rates can raise capitalization rates, reduce transaction volume and increase borrowing costs across regions. Lower volume matters because it leaves fewer sales to support a valuation.

For office and multifamily loans, refinancing may be difficult where rent growth and property values are pressured and rates are higher. Both ceilings tighten at once in that setting.

How a large rate move reaches a loan sized years earlier

Major central banks raised rates by more than 500 basis points in just over 18 months, taking financing rates in the US and UK to their highest levels since before the global financial crisis. A loan sized before that move is tested at the new level when it matures.

The arithmetic is direct. For an interest-only loan, the income-based ceiling equals net operating income divided by the product of the required ratio and the interest rate. With income and the ratio held constant, a rate that rises by a third cuts that ceiling by a quarter.

Floating-rate loans take the increase sooner. Rising rates raise repayment costs on floating-rate loans during the term, so coverage can erode before the maturity date arrives. A fixed-rate loan keeps its old cost until the term ends and then resets to the market.

The collateral ceiling moves as well. If the capitalization rate rises with financing rates, the same income supports a lower value, and the loan-to-value ceiling drops with it.

Worked example: refinancing a $10 million interest-only loan at 6 percent and at 8 percent

This hypothetical example sizes the same $10 million interest-only balance in two cases on the same basis: one year of net operating income, no financing fees and a single illustrative lender. That lender requires a minimum coverage ratio of 1.25x and a maximum loan-to-value ratio of 65 percent.

Base case, step one: net operating income is $1.2 million, and both the capitalization rate and the new interest rate are 6 percent. Value equals $1.2 million divided by 0.06, or $20 million. The collateral ceiling equals $20 million multiplied by 0.65, or $13 million.

Base case, step two: allowed debt service equals $1.2 million divided by 1.25, or $960,000. Dividing $960,000 by 0.06 gives an income ceiling of $16 million. The collateral ceiling of $13 million is lower, so it controls. Proceeds of $13 million exceed the $10 million balance by $3 million, so the loan repays in full.

Base case, step three: interest on $10 million equals $10 million multiplied by 0.06, or $600,000. Coverage equals $1.2 million divided by $600,000, or 2.00x. Loan-to-value on the $10 million balance equals $10 million divided by $20 million, multiplied by 100, or 50 percent.

Stressed case, step one: net operating income falls to $1 million, and both rates rise to 8 percent. Value equals $1 million divided by 0.08, or $12.5 million. The collateral ceiling equals $12.5 million multiplied by 0.65, or $8,125,000.

Stressed case, step two: allowed debt service equals $1 million divided by 1.25, or $800,000. Dividing $800,000 by 0.08 gives an income ceiling of $10 million. Interest on the $10 million balance equals $10 million multiplied by 0.08, or $800,000, so coverage equals $1 million divided by $800,000, or 1.25x. The loan meets the coverage test at the full balance.

Stressed case, step three: the collateral ceiling of $8,125,000 controls, since it is below the $10 million income ceiling. The funding gap equals $10 million minus $8,125,000, or $1,875,000. Loan-to-value on the full $10 million balance equals $10 million divided by $12.5 million, multiplied by 100, or 80 percent.

Between the cases, the loan stays current, coverage still meets the minimum, and yet $1,875,000 of principal has no replacement source. The collateral test produced the gap, and a coverage check alone would have shown none.

How the pressure differs by property type and by loan vintage

The same rate move lands differently depending on what is happening to income. Reduced office use pressures office rents and occupancy. Lower business travel pressures hospitality revenue. Inflation adds to operating costs across property types. Each channel reduces net operating income, and the sizing formula carries that reduction straight into a smaller income ceiling and a lower value.

Average figures can mislead. In one quarter’s loan-level data for office and downtown retail mortgages, average current loan-to-value ratios were 50 to 60 percent. An average blends loans with large cushions and loans with thin ones, and the loans that fail a lender’s ceiling sit in the thin tail.

Geography adds a second layer. Vacancy rates in most major metros of one large state remain high despite declining modestly, and refinance risk there remains a concern with rates still high.

Vintage matters through timing. Maturing loans from a recent vintage are meeting softer property performance, stricter bank underwriting and reduced lender appetite at the same moment. A replacement quote that assumed only a different interest rate would miss the income and lender-appetite effects.

From single loan gaps to bank portfolio exposure

A maturity schedule shows when principal comes due. It does not show whether replacement proceeds will cover it, so exposure estimates need loan-level proceeds assumptions.

Volume still matters. One industry estimate of maturing US commercial property loans puts a peak year near $500 billion, about $425 billion a year for the next three years, and more than $1.7 trillion across the four.

Maturity pressure shows up in how banks rank their worries. In one survey of bank staff, 54 percent named maturity or refinance risk as the chief commercial real estate concern, ahead of a debt cost that exceeds property yield at 18 percent and inability to value properties at 14 percent.

Credit data shows the early stage of the process. In the latest supervisory report, commercial real estate delinquencies had risen above pre-pandemic levels, and banks had raised credit-loss allowances in anticipation of further deterioration in asset quality.

Spread-out maturities give lenders and borrowers time to work out repayment solutions and in some cases allow prices to recover. Time helps where income or value improves, financing rates fall, principal amortizes, or new capital arrives.

The useful portfolio measure adds up loan-level gaps. Principal due minus replacement proceeds, floored at zero for each loan and summed under stated assumptions, shows how much repayment depends on something other than refinancing. That sum is a funding shortfall, and a loss estimate requires further analysis of collateral and recoveries.

Common mistakes when sizing a maturing commercial real estate loan

Reading a clean payment history as refinance capacity confuses the old contract with the new one. Payments reflect the old rate and the income at that time. In the stressed case above, coverage still met the minimum at the full balance, and the loan was still $1,875,000 short.

Using the coverage result as the proceeds figure leaves out the collateral test. Both ceilings apply, and the lower one controls. In the stressed case the income ceiling was $10 million and the collateral ceiling was $8,125,000.

Holding value fixed while income falls builds an inconsistent scenario if the capitalization rate also stays unchanged. If a property’s income falls while its appraised value is held fixed, the capitalization rate used to support that value must fall too, and a lower rate is a more aggressive assumption that a lender’s appraiser or underwriter will usually reject. Rising rates can push capitalization rates higher, which is the opposite direction.

Relying on an average loan-to-value ratio hides loans above the ceiling. A loan at 50 percent and a loan at 80 percent average 65 percent, which equals the ceiling in the example, yet the second loan exceeds it. Reported averages in the 50 to 60 percent range carry the same limitation.

Treating maturing principal as expected loss skips two steps. Principal due is a contractual amount, a funding gap is the unfunded part of it, and a loss depends on what the collateral and the borrower can still supply. Counting an extension as repayment adds a second error, because the due date moves and the principal stays outstanding.

Checklist questions for reviewing a maturing loan

What principal is contractually due at maturity? The test starts with the full balance, including any principal deferred through the term.

Which income figure and operating period feed the sizing? Coverage and value both divide the same net operating income, so a mismatch in definition distorts both ceilings.

Is the replacement debt interest-only or amortizing? The two structures produce different annual payments on the same balance and rate.

Which ceiling controls under the stated lender assumptions? The lower of the income-based and collateral-based amounts is the proceeds figure.

How did the capitalization rate move alongside the interest rate? Value responds to both income and the capitalization rate, so the collateral ceiling can fall even when coverage passes.

Is the existing loan fixed or floating? A floating-rate loan can face higher debt service during the term, while a fixed-rate loan faces market rates when it is refinanced at maturity.

What funds cover a positive gap? A shortfall with no identified source leaves the repayment plan incomplete.

What does an extension assume about income or value at the new date? More time changes the due date, and repayment still needs resources at that date.

How much of the portfolio’s maturing principal has a gap under stated assumptions? That subset is narrower than the full maturity schedule and is the figure that bears on exposure.
