A commercial real estate loan can look flawless for years. Payments arrive on time, covenants hold, and the loan sits in the performing column of a bank’s balance sheet until the day it matures and the borrower has to find new financing. That date, not a missed payment, is where trouble tends to surface. It explains why bank examiners keep returning to the same line item on regional bank balance sheets.
Large national lenders spread risk across credit cards, corporate lending, trading, and wealth management. Many regional and community banks do not have that cushion. Commercial property loans are often the most profitable lending a smaller bank can write, local relationships make them easy to originate, and over time they can grow into the dominant share of the loan book. When a concentrated portfolio meets higher interest rates and softer property values, supervisors see a stress test unfolding in real time, with actual borrowers instead of models.
The Refinancing Wall Behind the Worry
Many commercial loans are not built to be paid off over their stated term. They carry a balloon payment, so the borrower pays mostly interest for five, seven, or ten years and then refinances the remaining principal. That structure works when property values hold steady or rise and credit is cheap. It breaks when the borrower arrives at maturity with a building worth less than the loan and a new lender demanding a far higher rate than the original one.
At that point the bank must choose between a modification and a loss.
Office Gets the Headlines, but the Problem Is Wider
Office buildings are the obvious pressure point. Hybrid work has left many towers with empty floors, and each lease expiration gives a tenant the chance to downsize or leave. A building’s value rests on its income, so lower occupancy hurts once, and higher interest rates hurt again by raising the return investors demand before they will buy. Those two forces together can erase equity that once looked comfortable.
The reported numbers on a bank’s books can lag that reality. Appraisals are snapshots, and when few comparable buildings are changing hands, there are few fresh data points to anchor a new valuation. Imagine a loan written at a conservative loan-to-value ratio several years ago. If the appraisal behind it has not been refreshed, the ratio on paper may look healthy while the real cushion has thinned or vanished. Examiners tend to push banks to update valuations for exactly this reason.
Office is not the only category under review. Apartment loans written on aggressive rent-growth assumptions or with floating rates can strain once borrowing costs reset. Retail, hotel, and industrial properties each carry their own local risks, and a strong submarket can sit a few miles from a weak one. A portfolio that looks diversified by property type can still be exposed if every loan sits in the same metro area or depends on the same type of tenant.
Funding adds another layer. The bank failures of 2023 showed how quickly depositors can move when confidence slips, and a bank with visible commercial property stress can find its credit risk and liquidity risk feeding each other. A loss that might be absorbed over several years becomes harder to manage if deposits leave faster than loans can be sold or refinanced. Supervisors now look at the asset side and the funding side as a single question.
Extend and Pretend, or Honest Workout?
Banks have good reasons to work with borrowers instead of foreclosing. A modified loan that keeps paying is usually worth more than a seized building sold into a thin market, and forced sales can drag down the values of neighboring properties and the collateral behind other loans. Federal regulators acknowledged this logic in late 2023 with an interagency policy statement on prudent commercial real estate loan accommodations and workouts. It told examiners that reasonable modifications for borrowers who are still performing should not be criticized simply because the underlying collateral has lost value.
The difficulty is telling a real workout from a delay. A bank can extend a maturity, lower a payment, or allow interest to accrue, and the loan may continue to look healthy on paper while the underlying problem grows. If the property never recovers, reserves set aside too late leave the bank absorbing the loss all at once. Deciding which borrowers have a credible path and which are simply being carried is a matter of judgment, and that is where disagreements between banks and their supervisors most often begin.
What Supervisors Check First
The starting point is concentration. Interagency guidance issued in 2006 flagged banks whose construction and land development loans reached 100 percent of capital, or whose total commercial real estate lending reached 300 percent of capital alongside rapid growth, for closer scrutiny. Those figures are not hard limits, and a bank above them is not automatically in trouble. They work as triggers for questions about underwriting, risk management, and whether capital is sized for a downturn in property values.
After the ratio comes the evidence behind it. Examiners look for independent and recent valuations, stress tests that vary interest rates and vacancy instead of assuming a soft landing, and a board that can explain what it would do if a large share of maturing loans could not be refinanced. They also look at whether the allowance for loan losses matches the actual condition of the portfolio, and whether capital is strong enough to absorb losses without a rushed raise at a bad price.
The uncomfortable part is timing. Building reserves cuts into earnings today, while the losses they cover may not materialize for years, so a bank that reserves aggressively can look weaker than a neighbor that waits. The neighbor looks stronger right up until the maturity dates arrive.
