CMBS Delinquencies Surge: Office Sector Dominates Special Servicing Transfers
By Majid Radaei, RadCRE · · Industry Insights
CMBS delinquency rates are climbing, reaching 5.0% in April 2026, primarily driven by the struggling office sector. Special servicing transfers are accelerating, underscoring valuation challenges.
CMBS Delinquencies Continue Upward Trend, Office Sector at Forefront
The commercial mortgage-backed securities (CMBS) market is grappling with escalating delinquency rates, particularly within the beleaguered office sector. According to the latest data from Trepp, the overall CMBS delinquency rate rose to 5.0% in April 2026, a notable increase from 4.75% the previous month. This upward trajectory is largely attributable to continued stress in office properties, which now represent a disproportionate share of distressed debt.
The office delinquency rate hit 8.75% in April, significantly outpacing other property types. This trend reflects the sustained impact of hybrid work models, rising vacancies, and the substantial cost of capital for refinancing. Many office loans originated during a period of lower interest rates are now maturing into an environment where SOFR hovers around 4.31% and Prime at 8.50%, making refinancing difficult without significant equity contributions or loan restructurings.
Special Servicing Transfers Accelerate, Workout Outcomes Vary
The rise in delinquencies has naturally correlated with an increase in special servicing transfers. Recent reports indicate that nearly $7 billion in CMBS office loans were transferred to special servicing in the first quarter of 2026 alone. Major transfers include the $344 million loan on the Embarcadero Center in San Francisco and the $300 million loan backing 1740 Broadway in New York City, both emblematic of the challenges faced by older, less amenitized Class B and C office assets.
Workout outcomes for these transferred loans are varied. Some borrowers are pursuing loan modifications, often involving maturity extensions, interest rate adjustments, or partial principal repayments. However, special servicers are increasingly opting for foreclosure or deed-in-lieu of foreclosure as office valuations continue to decline. For instance, the foreclosure on the $100 million loan for the Gas Company Tower in Los Angeles last year highlighted the willingness of some servicers to move aggressively when capital stack imbalances become too severe.
For loans that successfully undergo modification, typical terms often include increased reserves, stricter reporting requirements, and a period of interest-only payments to alleviate immediate debt service burdens. However, the underlying asset valuation remains a critical challenge, with many office properties struggling to achieve pre-pandemic values, leading to potential future defaults even after initial workouts.
RadCRE Perspective
Majid Radaei, Founder of RAD Commercial Realty, notes, "The CMBS market's current distress, particularly in office, is a clear signal of the capital recalibration underway. We're seeing a significant portion of maturing office debt facing an impossible refinancing scenario at today's benchmark rates of SOFR + 300-600 bps for bridge loans, let alone standard CMBS. Many of these borrowers are operating at loan-to-value ratios far exceeding what traditional lenders are comfortable with right now. For our clients, this environment, while challenging, presents unique opportunities in identifying truly overlooked value-add assets or situations where capital stack rebalancing, potentially involving preferred equity or a significant equity injection, can turn around a distressed asset. We're seeing more opportunities in hotel investment sales and acquisition financing where we can leverage agency debt (Fannie/Freddie) or even SBA 7(a) for owner-operators, which maintain more favorable terms than the CMBS market is currently offering for troubled asset classes. The key for CMBS borrowers in distress is proactive engagement with special servicers and exploring all potential avenues, including recapitalizations with opportunistic debt or equity, before falling into foreclosure. Waiting is no longer a viable strategy."
Broader Market Impact and Future Outlook
While the office sector bears the brunt of CMBS distress, other property types like retail and multifamily have shown relative resilience, albeit with localized pockets of concern. The lack of liquidity for transitional assets across all sectors, coupled with the elevated cost of capital, means that originations for new CMBS conduits remain subdued. This scarcity of new paper further highlights the importance of astute asset management and proactive capital structuring for existing loans.
