U.S. banks hold roughly $3.09 trillion in commercial real estate debt, but smaller regional and community lenders carry nearly two-thirds of that exposure despite commanding only about 13.5% of industry assets, according to FDIC Call Report filings. The concentration leaves a narrow slice of the banking sector shouldering disproportionate risk as commercial property markets adjust to higher interest rates and remote work.
Regional bank CRE delinquency rates stand around 0.73% and 1.25%, the filings show. The commercial mortgage-backed security market tells a different story. In September 2026, the CMBS delinquency rate surged to 8.02%, the highest level since November 2020. The special servicing rate, which measures transfers due to default or imminent default, hit 11.49%, a 13-year high.
Trepp data shows that even after a single $975 million loan cure pulled the headline CMBS rate to 7.87%, stress deepened across every major property type. Office climbed 17 basis points to 12.33%, multifamily rose to 8.09%, and retail jumped 63 basis points to 7.21%.
The divergence between bank-reported and CMBS delinquencies reflects discretionary accounting and extend-and-pretend modifications rather than superior underwriting, the source material suggests. Under ASU 2022-02, banks must report loan modifications only when they determine a borrower is experiencing financial difficulty. Banks themselves make that determination, allowing underwater borrowers to receive balloon-payment extensions classified as routine renewals.
A year ago, the St. Louis Fed showed banks officially reported just $27.7 billion in modified CRE loans for borrowers in financial difficulty, less than 1% of the market. Federal Reserve Board research by David Glancy and New York Fed supervisory data from Crosignani and Prazad reveal that large banks actually extended roughly half of all maturing CRE loans.
Research by Columbia, Wharton and MIT finds 53% of U.S. regional banks already exceed the 300% CRE-to-capital regulatory threshold, with a median concentration of 310%. Commercial mortgages represent 38% of total assets at a typical regional bank versus just 8% at money-center banks.
Third-quarter earnings from Western Alliance Bancorporation and Zions Bancorporation showed strength, with the former lifting reserve coverage to 118% and growing earnings per share 7.5% to $2.45. Zions posted a 20% EPS jump to $1.78. East West Bancorp delivered record third-quarter revenue and EPS of $2.76 with nonperforming assets at 0.30% of total assets and a common equity tier 1 ratio above 15%. Banc of California rebounded with a 21% EPS gain and wider lending margins after offloading $827 million in commercial real estate and construction loans during the second quarter.
