Methodology
This study ranks U.S. states by the signed % rate change from their most-recently-effective commercial-insurance rate filing captured in the GBC Rate Index™ tracker as of June 3, 2026. Data is sourced from public SERFF (System for Electronic Rate and Form Filing) filings on each state's Department of Insurance portal, plus NCCI advisory loss-cost filings, ISO commercial-lines filings, and non-NCCI bureau filings (WCIRB CA, NYCIRB NY, NJCRIB, PCRB PA, WCRB WI, Oregon DCBS) and monopolistic-state funds (Ohio BWC, Washington L&I, Wyoming DWS, North Dakota WSI).
Each captured filing with a stated % rate change contributes its signed % to the state's most-recent-effective ranking; states are sorted by signed % DESC for the rising-rates table (positive = increase). Filings without a clean signed % (per-vehicle base rates, LCM-only filings, rule revisions) are excluded from this study but tracked in the underlying index. Methodology lives at /methodology; the live tracker is at /insurance-rate-changes; the composite directional index is at /rate-index.
Expert commentary
"The 2026 commercial-insurance picture is bifurcated. The composite is falling — most states are cutting WC and standard lines on the back of strong reserves and softening loss trends. But the states that are RISING are rising hard, and they're concentrated in specific line/peril combinations: catastrophe-prone property in coastal Southeast, comp in states absorbing recent benefit-level changes, commercial auto where the post-2022 hard market hasn't fully unwound. The granular state-line view is the only way to see this without averaging it away."
