A statewide rate change is one blended number, but Cincinnati Insurance did not move every household by the same amount. Its own filing reports the spread: the largest increase in the book was about +76.7% and the largest decrease about −0.2%. So inside a “+16.7% average,” some Cincinnati Insurance households in Illinois were raised far more than the headline and others were cut. Where you land depends on your ZIP, home age, roof and claims history.
Other Illinois insurers are cutting.
An increase is only worth acting on relative to the alternatives, and in Illinois the direction is not uniform: Pekin (−2.1%) filed decreases in the same period. A Cincinnati Insurance increase alongside competitor cuts is the clearest signal there is that the market has moved and your renewal has not.
