Office CMBS Delinquency Rates Hover Near Record Highs Amid Maturity Wall Crisis
The commercial mortgage-backed securities (CMBS) market continues to exhibit severe structural distress, with office properties bearing the brunt of the refinancing friction. Despite minor monthly fluctuations, delinquency rates for office-backed CMBS remain near historic highs, driven by the massive maturity wall of loans locked into low interest rates.1
June 2026 Delinquency Readings
According to the Trepp June 2026 CMBS Delinquency Report, the overall U.S. CMBS delinquency rate decreased by 20 basis points to 7.35%, down from its May level, primarily due to a large lodging sector cure. However, the office CMBS delinquency rate edged up by 4 basis points to 11.57%.
This elevated level remains close to the all-time high of 12.34% set in January 2026, which surpassed the previous peak of 11.76% from late 2025. The persistent double-digit delinquency rate in office CMBS stands in stark contrast to other major commercial real estate sectors, such as:
- Industrial: 1.20% (down 11 bps in June)
- Lodging: 5.22% (down 79 bps in June)
- Retail: 6.91% (up 30 bps in June)
- Multifamily: 7.23% (up 28 bps in June)
Newly Delinquent Collateral
In June 2026 alone, newly delinquent loans totaled $2.64 billion. The five largest newly delinquent loans accounted for $998.9 million of this total, featuring high-profile assets including an office complex in New York, a mixed-use tower in Minneapolis, a super-regional mall in Southern California, and a Manhattan multifamily property. This ongoing distress confirms that refinancing friction remains acute, particularly for older, office-heavy collateral that cannot meet the underwriting standards of a 4.57% 10-year Treasury yield environment.
