Who Owns Cincinnati Insurance?

Four independent insurance agents founded The Cincinnati Insurance Company in 1950: John J. Schiff, Robert Schiff, Chester Field, and Harry Turner. Frustrated with insurers that treated agents as interchangeable sales channels, they built a company whose central promise was that local agents and local claims representatives would make decisions close to the customer.

The model differentiated the young insurer. Claims representatives were empowered to inspect losses and settle claims in person, an approach that won durable loyalty from the agencies appointed to sell its policies. Growth was disciplined rather than national in scale: the company expanded state by state, appointing established agencies in each market.

The 1968 formation of Cincinnati Financial Corporation as a holding company created room to diversify. The group added life insurance through The Life Insurance Company of Cincinnati in the early 1970s and built out its standard market property casualty group with The Cincinnati Casualty Company and The Cincinnati Indemnity Company. A merger with Inter-Ocean Life and Casualty gave the life operation scale.

Later decades extended the footprint to 46 states and added specialty operations. The excess and surplus lines business, marketed through Cincinnati Specialty Underwriters and the CSU Producer Resources brokerage, gave agents an outlet for harder-to-place risks. In 2015 the group launched Cincinnati Re for assumed reinsurance, and in 2019 parent Cincinnati Financial acquired London-based Cincinnati Global, the Lloyd's managing agent for Syndicate 318.

The first quarter of 2025 produced the largest catastrophe loss in the company's history when California wildfires drove claims across its property book. The brand still finished FY2025 with a 94.9% combined ratio, its 14th consecutive year of underwriting profit, within management's long-term target band of 92% to 98%.
