U.S. Office Vacancy Crisis Spreads to CMBS Investors
nashnova research
US office CMBS delinquency hit 12% last month — above post-2008 levels — with roughly $64 billion in office debt maturing over the next two years, nearly $40 billion already flagged. Losses are turning real.
How did an 83-story Chicago tower become the crisis poster child?
Landlord 601W bought the Aon Center in 2015 for $712 million, then refinanced — $536 million of the debt was packaged into CMBS (commercial mortgage-backed securities — pools of commercial-property loans sold to bond investors).
By May this year the building was valued at just $195 million, less than a third of the purchase price. The loan matured in July; 601W asked for a three-year extension and was "unequivocally denied."
This means → when collateral is worth a fraction of the outstanding loan, lenders have no incentive left to keep extending.
Why has the "wait it out" strategy collapsed?
For six years after COVID, lenders bet on two things: rates would fall and workers would return to offices. Neither bet has paid off.
The Fed hiked again last week and signaled further tightening — there is no visible window for borrowing costs to ease.
In plain terms = the playbook was "hold on, things may improve." With rates still rising and vacancy stuck, waiting only deepens the loss.
What does a 12% CMBS delinquency rate actually signal?
Office CMBS delinquency reached 12% last month, per Trepp — near its all-time peak and above the post-2008 financial-crisis level.
Dan McNamara, CIO of hedge fund Polpo Capital Management, called it "one of the most alarming signals," adding that the rate will keep climbing as more loans mature.
This reflects a sector-wide credit stress, not isolated property trouble.
$64 billion in maturing debt — what can borrowers do?
Roughly $64 billion in CMBS office debt matures over the next two years. Nearly $40 billion is already delinquent, in default, or on a watchlist.
Borrowers face two choices: inject fresh capital into depreciated assets, or walk away and hand the loss to lenders.
A Deutsche Bank report showed that distressed office sales this year closed at prices 20% below recent appraisals. In plain terms = appraisers were already marking down; actual sale prices discount even further, partly because servicing fees eat into recoveries.
Where is the geographic epicenter shifting?
New York and San Francisco were hit hardest early in the pandemic, but a finance and tech recovery is warming parts of those markets.
Pressure is migrating to Chicago, Denver, and Los Angeles — cities with thinner demand pipelines and persistently high vacancy. Downtown Chicago office vacancy now stands at 27%.
Of the nearly $1.7 billion in Chicago office CMBS loans maturing this year, $1.45 billion is already delinquent. This means → virtually every maturing loan in the city is in trouble.
What is the next critical checkpoint?
The Aon Center is now the third-largest US office CMBS in special servicing or 60-plus-day delinquency, behind only Worldwide Plaza and 230 Park Ave. in New York, according to J.P. Morgan research.
601W says it is still negotiating a new extension, but loan documents show any short-term deal would require the owner to make "substantial upfront and ongoing capital commitments."
Josh Morris, global real-estate partner at Davidson Kempner, put it bluntly: "The hope that rates would come down has died. People are increasingly accepting we are in a different cycle." Whether the delinquency rate can plateau at these highs — or keeps climbing — will determine the ultimate scale of losses across the sector.
