2023 2024 2025¹
Total Filings 4,508 3,696 (-18%) 1,222 (YTD through Q2)
Average requested/approved rate impact +8.5% +4.7% +0.5%
Pct. of filings ≥ +10% 35% 18% 3%
Pct. of rate decreases <1% 15% 45%
Total written-premium affected $31.5B $12.5B $2.7B


The rate‑hike cycle is over.
 Average impacts have fallen 85% since the Q3‑2023 peak, and almost half of all 2025 filings now lower or hold rates flat.

 Trend lines your C‑suite will care about

  1. Sharp deceleration, not just moderation - Average impacts slid from 9% in Q3‑2023 to 0.5% by Q2‑2025.  Carriers are no longer “catch‑up pricing” for inflation; they are pivoting to retention defense and selective give‑backs.
  2. Filings are fewer, but still frequent - Volumes fell only 9% year‑over‑year.  Instead of one big filing, carriers are tranching multiple sub‑1% filings—a tactic executives should recognize as a regulatory‑risk hedge.
  3. California remains the outlier - Despite the softening market, California alone accounts for $7.8B of cumulative premium change (2023‑25) at a 16–19% average impact, more than the next three states combined.  Expect heightened political scrutiny.
  4. Carrier divergence is widening - Nationwide and State Farm posted negative average impacts in 2025 (‑1.9% and ‑0.9%), signalling an aggressive retention play.  By contrast, Farmers and Liberty still push mid‑single‑digit increases.
  5. West > East > South > Midwest on rate appetite - Regional average impacts run 6.5%, 6.5%, 5.7%, 4.8% respectively, confirming that loss‑cost relief is arriving first in the Midwest while catastrophe‑exposed West and East remain elevated.

Observation Why it matters
Rate decreases soared from 23 filings in 2023 to 131 in 2025 (87% loss severity, +mileage based credits). Signals insurers are confident that frequency suppression (telematics, usage based programs) is over offsetting inflation.
Total written premium affected keeps rising even as impacts fall. Carriers are leveraging book roll or territory mix filings—spreading smaller changes across larger exposures.
Texas filings: high premium ($6.6 B) but only 4.7 % average impact. Reflects regulator messaging that magnitude is capped; carriers respond with frequency instead.
High impact (≥ +10 %) filings collapsed from 35 % to 3 % of activity. Regulator push back is biting; insurers are switching to “micro cycle” filings to stay below political radar.

Emerging concepts to monitor

Concept Signals in the data Executive implication
Micro cycle filings Spike in <1% filings each quarter Re-tool pricing ops for continuous rather than annual cycles.
Telematics-driven give backs Negative impacts concentrated at Nationwide & State Farm Expect margin compression for non telematics books; accelerates adoption race.
AI/ML segmentation scrutiny CO, NY, WA filings cite “predictive fairness analyses” Budget for compliance analytics & model governance tooling.
Cat risk capital loadings CA and FL continue double digit increases while national trend falls Diversification and reinsurance strategy, not just pricing, will drive ROE.

Action checklist for leadership

  1. Re‑forecast top‑line growth assuming sub‑2% personal‑auto rate lift through 2026; offset with retention uplifts and cross‑sell plays.
  2. Invest in real‑time rating infrastructure to enable micro‑cycle filings and telematics credits without bloating filing volumes.
  3. Prepare a multi‑state regulatory engagement plan—especially in California, New York, Colorado—focused on fairness/AI narratives.
  4. Revisit catastrophe reinsurance layers; underwriting margin alone will not cover CA/FL volatility as rate caps tighten.
