As of August 2026, Chicago recorded the highest commercial mortgage-backed securities (CMBS) delinquency and special servicing rate among major playoff cities at 25.3 percent. This local distress rate increased by 4.7 percentage points year-over-year.
Why it matters
The elevated distress in Chicago is largely driven by office assets, which account for nearly half of total national distressed CMBS balances. This trend highlights broader risks for commercial real estate portfolios, particularly as loans face refinancing challenges at maturity.
The Chicago CMBS distress rate climbed to 25.3 percent in August, significantly higher than the 10.9 percent national average. This figure is underscored by the Aon Center, where a $536 million loan failed to repay at maturity as the property's appraised value dropped to $195 million.
The players
Aon Center
A major office tower whose $536 million loan failed to repay upon maturity in July 2026.
The details
Loans enter a distressed state when they fall delinquent or are transferred to special servicing, typically due to an inability to meet repayment terms. In the case of large office properties, this often occurs when loan maturity dates arrive and current market valuations no longer support refinancing the original debt balance. This process directly impacts the performance of CMBS portfolios, which are collections of commercial loans pooled together as investments.
Timeline
August 2026: Chicago CMBS distress reached 25.3 percent.
July 2026: The Aon Center loan matured and was not repaid.
September 2026: Preliminary national CMBS distress reached 10.8 percent.
Money Landscape
Chicago's commercial real estate market is currently experiencing distress levels that significantly exceed the national office CMBS rate of 16 percent. This local trend sits as a stark outlier compared to other major urban markets that have seen more moderate or declining delinquency figures.
Local property owners and investors should monitor how high delinquency rates affect future credit availability and commercial real estate valuation trends in the area. Consult with a qualified financial or tax professional to understand how shifts in local asset values might impact your specific portfolio.
The takeaway
Commercial loan distress in Chicago highlights the risks posed by significant drops in office property valuations, such as the decline seen at the Aon Center. Investors should keep an eye on upcoming loan maturity dates and regional distress data as indicators of future credit market health.
