Over $1 trillion in commercial mortgages must refinance from rates near 1.35% into a market where the 10-year Treasury yield hits 5.24%.
Commercial mortgage delinquencies have surged to 12%, just below January’s all-time record, as landlords walk away rather than refinance at crushing new rates.
Banks now carry a record $3.14 trillion in commercial real estate loans, putting bank shareholders and REIT investors directly in the path of landlord defaults.
Over $1 Trillion in Commercial Mortgages Is Coming Due
More than $1 trillion in commercial mortgages must be refinanced. Most of that debt was locked in at very low rates five to 10 years ago, and it now has to be rolled into a much more expensive market. The stress is already visible. Commercial mortgage delinquencies have reached 12%, just under January’s all-time high of 12.3%.

The $1 trillion figure is an estimate of maturing debt across commercial property owners. It is a market-wide number. This number determines the risk for landlords, the banks that lend to them, and the long-term investors who own shares in both.
Why Refinancing Hits Landlords So Hard
Refinancing updates a landlord’s borrowing cost. Take an owner who financed a building when the 10-year Treasury yield was at its five-year low of 1.35% on December 3, 2021. That owner now refinances against a 10-year yield of 5.24% as of October 1, 2026. The 10-year yield is the benchmark that sets mortgage rates and corporate borrowing costs. When interest costs rise, less of a building’s rent is left over to pay the loan.
Beyond higher rates, property values are lower today, lenders have tighter underwriting standards, and the spread of remote and hybrid work has cut demand for office space. A lower property value supports a smaller loan. Tighter standards mean lenders want the owner to put in more cash. Landlords who can’t cover that gap have one way out, and a growing number of landlords are taking it by walking away from their properties.

Banks hold a large share of this risk. Commercial real estate loans at all U.S. commercial banks reached $3,138.00 billion as of September 23, 2026. That is the highest level in Federal Reserve data going back to October 2016. The total grew by $108.53 billion over the past year, up 3.6%. Lenders are carrying a record amount of commercial property debt just as refinancing gets harder.
Market Reaction: Bond Yields Keep Climbing
The bond market shows the pressure most clearly. The 10-year Treasury yield rose 0.45% over the past month (+9.4%) and 1.12% over the past year (+27.2%). It hit a five-year high of 5.29% on September 30, 2026. On October 2, 2026, the Treasury yield curve showed the 10-year at 5.28% and the 5-year at 5.06%.
The Federal Reserve is raising short-term rates. The upper bound of the federal funds rate went to 4.00% on September 17, 2026, up from 3.75%.
The 10-year yield ranks in the 99.7 percentile of its five-year range and is well above its five-year average of 3.833%. Delinquencies are close to a record. Property values have dropped, so owners have less equity to borrow against. Tighter lending standards limit how much new debt they can get. Remote work continues to drain demand for office space.
Many borrowers hoped rates would fall before their loans came due. That hope carries a risk Marketplace described on September 24, 2026 while talking about home mortgages. Chris Mayer of Longbridge Financial told the program, “It’s not simple to predict mortgage rates. They could easily go up rather than down.” He added that if property prices fall, owners lose the ability to refinance. Commercial landlords now face both problems: rates went up and values went down.
The risk reaches past landlords. Banks hold a record $3,138.00 billion in commercial real estate loans. Every property an owner walks away from leaves a lender with a building worth less than the loan against it. Owners of bank stocks and real estate investment trusts (REITs) bear that risk through lower earnings and pressure on dividends.
Bottom Line for Long-Term Investors
The $1 trillion in coming due debt is the clearest measure of how much the change from cheap money still costs commercial real estate. Three things to watch: the Federal Reserve’s weekly bank lending data, whether delinquencies pass the 12.3% record, and the direction of the 10-year Treasury yield. Income-focused investors who hold banks or property owners should look at how much of each company’s debt comes due soon and how much office space it owns. Landlords cannot avoid this refinancing, and current rates make it expensive.
