"The largest increase was among CMBS loans, driven by rising delinquencies in both multifamily and office properties. Delinquency trends continue to reflect differences in property type, loan structure, geography, and borrower profile."m MBA's quarterly analysis looks at commercial delinquency rates for the top five capital sources: commercial banks and thrifts, commercial mortgage-backed securities (CMBS), life insurance companies, and Fannie Mae and Freddie Mac. Together, these investors hold more than 80% of commercial mortgage debt outstanding. MBA's analysis incorporates the measures used by each capital source to track the performance of their loans. Because each tracks delinquencies in its own way, delinquency rates are not directly comparable from one group to another. As an example, Fannie Mae reports loans receiving payment forbearance as delinquent, while Freddie Mac excludes those loans if the borrower is in compliance with the forbearance agreement.
