A Falling CMBS Delinquency Balance Is a Plateau, Not a Peak

Trepp's August read on the CMBS loan universe puts the delinquency balance at just over $47.42 billion, a slight decline, and the firm suggests peak delinquencies may already have occurred. The more useful half of the same note is the caveat: as problem loans inside the $604-billion-plus universe are worked out, Trepp says, new defaults arrive to take their place. A roll that sheds loans at one end and takes them on at the other is not a market in repair but one holding a level, and the level is high.

August's balance is roughly three-quarters of the nearly $63 billion high Trepp dates to April 2011, and close to 4.7 times the $10 billion low recorded in early 2020. Delinquencies began climbing again in mid-2023 as interest rates rose, and the increase since then has retraced about 71% of the decline from the 2011 peak to the 2020 low. A small monthly decline from that height is a plateau, the kind that forms when the resolution pipeline and the new-default pipeline run at anything close to the same speed, exactly what Trepp describes when it says worked-out loans are being replaced by fresh ones.

Office loans set that pace, with buildings in the sector accounting for just more than 42% of the late-paying balance across 467 office loans more than 30 days late, roughly $19.9 billion of the $47.42 billion, or about $43 million a loan if the loans were alike. Trepp is explicit that they are not alike: the dollar balance is driven by a few very large loans, and the one the report names is the $85 million securitized portion of a $940 million senior loan against Manhattan's Worldwide Plaza, which has passed into the hands of a receiver. That $85 million is a little over nine cents on the senior loan, while the other 91 cents sits outside the securitization whose delinquency rate is being counted.

That ratio tells you how much the headline can say. If large office financings keep arriving in the trust with a thin securitized slice, Worldwide Plaza's roughly 9% is the example in hand, not a proven norm, then the CMBS delinquency rate will cover a shrinking share of the office loans that go wrong, while office remains the sector that dominates the roll. Dollar-weighting compounds the problem: because a few assets carry the balance, a month's movement is a statement about a handful of properties; small loans can accumulate without moving the headline at all, and one large resolution in the other direction can move it a lot.

The other half of Trepp's caveat is about what "worked out" means. Resolving a problem loan and getting paid on it are different events, and only the second one reduces the debt. This cycle's maturities are being met with structured extensions and capital stacked beneath or beside existing loans rather than with discounted sales, which reprices risk without retiring it. A loan modified to a payment the borrower can make stops being 30 days late, and the balance falls without a dollar of principal going away; the mechanism that holds the delinquency number down is the same one that keeps the maturity calendar full.

The composition of the next wave looks different from the roll being reported now: office dominates today's delinquencies, but our September cohort work found retail displacing office as the most impaired sector among maturing loans, with more than a quarter of that balance sitting below a 6% debt yield. The 2023 conduit multifamily vintage already produces delinquencies on thin DSCR cushions, and the larger 2024 vintage was written thinner still. Today's balance is a backward-looking document about loans underwritten in a different rate world; the replacement defaults Trepp flags belong to this one.

The replacement rate deserves watching: how much new delinquency arrives against how much balance clears. A month in which the balance falls by more than new defaults add back would be the first real evidence of the peak Trepp suspects; a run of August-sized declines would be paperwork moving faster than credit. The structural marker matters just as much: if the next sizable office loan to land in a trust comes with a securitized slice as thin as Worldwide Plaza's, the delinquency rate will keep losing resolution on the sector that still dominates it.
