Nearly 30% of outstanding self-storage CMBS balances are now on watchlists, even as delinquency remains extremely low at 0.05%, according to Trepp data. The sector has approximately $23.7 billion in current CMBS exposure across about 4,800 loans and 15,600 properties. Watchlist concentration is highest in loans originated between 2021 and 2024, with the 2023 vintage showing an 84.4% watchlist share and the 2024 vintage at 56.6%. Geographic pressure is evident in markets like Atlanta, where 50% of balances are on watchlists, and Chicago at 48%, while New York remains more stable at 16.7%. Supply growth in Sun Belt markets and a housing slowdown are contributing to the early credit stress signals.
