Definition:Open rating
📊 Open rating is a regulatory framework under which insurance carriers are permitted to set their own premium rates without obtaining prior approval from the state insurance department, though they are typically required to file those rates for review. Also referred to as "no-file" or "file-and-use" rating in some jurisdictions (depending on the specific variant), open rating stands in contrast to prior approval systems where regulators must explicitly authorize rates before they can be used in the market.
⚙️ In an open rating environment, an insurer develops its rates using its own actuarial analysis, loss experience, and competitive positioning, then implements them — sometimes immediately, sometimes after a brief waiting period following the filing. The state regulator retains the authority to review rates after the fact and can disapprove them if they are found to be excessive, inadequate, or unfairly discriminatory. Some open rating laws still require insurers to file supporting rate documentation, including loss ratio projections and expense assumptions, so that regulators can conduct retrospective audits. The degree of flexibility varies by state and by line of business; commercial lines often enjoy more open rating latitude than personal lines like auto and homeowners.
💡 Proponents argue that open rating fosters competition and innovation, allowing insurers to respond quickly to shifting risk conditions — particularly valuable in volatile segments like property and cyber. Critics counter that insufficient regulatory oversight can lead to predatory pricing or to insolvency risk if carriers undercut each other to unsustainable levels. For insurtech companies and MGAs that rely on rapid product iteration and dynamic pricing models, open rating jurisdictions are especially attractive because they shorten the time from rate development to market launch. Understanding the regulatory posture of each state on the open-versus-prior-approval spectrum is essential for any carrier planning a multi-state product rollout.
