The 30% Signal: A CMBS Warning Sign That Has Preceded Every Major CRE Correction of the Last 20 Years

Trepp's report identifies a metric—the ratio of acquisition financing to total issuance in CMBS—that has preceded every major commercial real estate correction over the past 20 years, with a critical threshold at approximately 30% of sector issuance. The analysis demonstrates that this signal appeared across all major property types in 2007 (office at 39%, retail and multifamily close behind) and again in 2021 in multifamily (47%) and lodging (63%), each time followed by deteriorating loan performance and rising delinquencies, with 252 multifamily and office loans from 2020-2022 already delinquent or in special servicing as of the report's publication.
