Underwriting performance for the U.S. commercial lines market in 2024 remained nearly flat from the previous year, Fitch Ratings reports. Overall, the industry saw a 97% combined ratio when excluding mortgage insurance and financial guaranty. This makes 2024 the fourth consecutive year the sector reported an underwriting profit.

Workers’ compensation remained the top performer among the major commercial segments, posting an 89% average combined ratio from 2020 to 2024. Fitch’s report notes that workers’ comp also remained the primary source of favorable reserve development last year. This was offset by adverse development in other commercial lines; notably commercial auto and other liability.
