Central Insurance Company has filed a comprehensive rate revision with Arizona insurance regulators, proposing an overall 9.8% rate increase for owner-occupied homeowners policies (with an indicated change of 10%). The company is advancing a major analytical overhaul by adopting by-peril granularity in its rate indication methodology—described as the most significant shift in its actuarial process to date.

The strategic pivot utilizes AIR catastrophe models to segregate catastrophe exposures by peril—allocating wildfire losses to the Fire peril bucket, hurricanes to Wind, and so forth—resulting in more precise pricing by geographic and risk segment. ISO data supports loss-trend estimations, compensating for the insurer’s small market size in Arizona.

The company previously executed a significant 37.1% rate increase effective November 1, 2025.

Filing submitted February 6, 2026; new business effective April 1, 2026; renewals effective May 1, 2026.
