Ohio's insurance divide: who benefits from the rate truce

OHIO'S AUTO insurance market is splitting in two. On one side, independent carriers such as Branch and Nationwide's open company are filing rate cuts of around 10%. On the other, large carriers including Allstate and Progressive are still raising prices, albeit modestly. The surface story is that inflation is easing and claims are stabilising. The deeper one is that the market is reallocating pricing power, and consumers who do not shop will pay the difference.

Ohio auto premiums climbed more than 30% cumulatively from 2020 to 2024, according to industry data tracked by InsuranceGeek, a rate-monitoring site. Three forces converged: used-vehicle values spiked as supply-chain disruptions made cars harder to replace; repair labour and parts costs rose well above general inflation; and medical costs flowed through bodily-injury claims. Insurers raised rates to recover losses. Now that combined ratios are improving, the pressure has reversed for some-but not all.

The reason for the divergence lies in underwriting discipline, not in altruism. Ohio carriers have historically maintained stronger loss ratios than the national average-mid-60s versus nearly 70% nationwide, according to 2024 data compiled by Ohio Insurance Agents. Progressive posted a loss ratio of 59% and a combined ratio of 81%, indicating it is writing profitable business even as it raises rates. Allstate's loss ratio was 58%, similarly healthy. State Farm, Ohio's largest carrier at 21% market share, reported a 73% loss ratio and a 99% combined ratio, meaning it is roughly breaking even on underwriting alone. The incentive for carriers with thin margins is to recover every last dollar from renewals. For those already profitable, the incentive is to cut rates and steal customers.

Branch filed a 10% average auto rate decrease in October 2025, effective for new business, and introduced an advanced-quote discount of up to 16% for policies quoted well in advance. Nationwide's open company followed with a similar 10% cut in December 2025. State Farm announced roughly $4.6 billion in national auto rate reductions averaging around 10%, though it did not disclose Ohio-specific figures. Meanwhile Allstate filed a 2% increase for 2026 and Progressive carried low-single-digit hikes. The gap between a 10% cut and a 2% increase is 12 percentage points-the equivalent of over $150 a year for the average driver. That is not a rounding error; it is a structural transfer of wealth from patient customers to their carriers.

The market structure amplifies the problem. Ohio's private-passenger auto market generated over $9 billion in direct written premiums in 2024, making it one of the largest in the Midwest. Independent agents-brokers who write for multiple carriers-place about 64.5% of all policies in Ohio's P&C marketplace. That distribution channel should, in theory, help consumers compare prices. In practice, it creates inertia. Agents have an interest in retaining existing relationships, and customers tend to stay with the person they know rather than the carrier that is cheaper. Loyalty is rewarded with higher premiums. The Luddites at least had the decency to be honest about what they wanted.

To be sure, Ohio is faring better than many states. The national average full-coverage premium fell 6% in 2025 to $2,144, according to Insurify, a rate-aggregation firm, with 39 states seeing prices decline. Ohio is not among the worst-off. Insurify projects a modest 1% national increase for 2026, which would bring the average to $2,158. Some states have seen much worse-New Jersey's average rate climbed 20% last year; Washington, D.C. is at nearly $4,000, almost double the national average. Ohio's regulators, for their part, require carriers to file rate changes through the SERFF system, making the data publicly searchable. That is more transparency than many states provide.

Yet the story is not simply that rates are stabilising. One complication looms: tariffs. Insurify notes that the full effects of American tariff policy have not yet flowed through to vehicle repair costs. If parts prices rise as a result, the firm projects an additional 3 percentage points on national premiums, taking its 2026 forecast from a 1% increase to 4%. Auto insurers would pass those costs to drivers as a matter of arithmetic, not malice. Tariffs, like all taxes, find their incidence where consumers have the least bargaining power. In Ohio, that is the renewal customer who forgets to shop.

What should be done? Regulators could require clearer disclosure of rate differentials between new and renewal customers, as some states have begun to do. Ohio's Department of Insurance publishes useful consumer guides on how rates are determined, but it has not forced carriers to explain why two drivers with identical records and vehicles pay different prices. A simple rule-requiring that renewal notices include the current rate available for a new customer with the same risk profile-would go a long way toward restoring competition. It would not fix the underlying consolidation problem; the five largest insurers account for nearly two-thirds of the national market, according to the National Association of Insurance Commissioners. But it would make shopping less costly for those who need to do it.

The broader lesson is about market structure, not individual premiums. Consolidation, captive distribution, and consumer inertia combine to reward incumbents and penalise loyalty. The carriers cutting rates in Ohio are not doing so from charity; they are competing for share in a market where the easy gains have been made. The ones still raising rates have the leverage to do so. The question for Ohio regulators is whether to let the divide widen, or to build the institutional friction that forces insurers to compete on price rather than on customer forgetfulness.
