US office CMBS delinquencies are surpassing post-2008 crisis levels:
The delinquency rate for US office CMBS rose +9 basis points in August to 12.0%, just below its all-time high of 12.3% set in January 2026.
The rate is now 6 times higher than in early 2023 and has moved above the ~10.8% peak reached after the Great Financial Crisis.
Meanwhile, the overall US CMBS delinquency rate has more than doubled since 2022, rising to 7.9%, its highest level since early 2021 and the highest excluding the pandemic in 13 years.
The pressure is becoming particularly severe in Chicago, where 27% of office space is vacant and $1.45 billion of the nearly $1.7 billion of office CMBS loans maturing this year are already delinquent.
Nationwide, around $64 billion of US office CMBS debt is maturing this year and next, with nearly $40 billion already delinquent, in default or on a watchlist.
The stress is being driven by persistently high borrowing costs, elevated vacancies and falling property values, while lenders are increasingly being forced to confront losses on loans that were previously extended.
The US commercial real estate downturn is shifting from delayed distress to realized losses.
