From analyzing quarterly rate filing data across all 50 states, a consistent pattern emerges: states with file-and-use systems show larger, faster rate swings, and Q1 2026 makes Texas the clearest example yet. S&P Global Market Intelligence's homeowners rate filing database, compiled through May 30, 2026, reveals that nine of the ten most financially significant homeowners rate increases filed nationally in the first quarter landed in Texas. The concentration is not coincidental. It is the predictable output of a regulatory structure that permits carriers to charge new rates on the filing effective date, before the Texas Department of Insurance (TDI) completes its actuarial review.
The scale is striking. Allstate Vehicle and Property Insurance Company filed an 8% rate adjustment affecting approximately 852,000 Texas policyholders, generating a calculated premium impact of $220.4 million, the largest single homeowners rate action in the country in Q1. Farmers Insurance Company of Texas filed a 22.7% increase with a calculated $199.2 million premium impact, the second largest nationally. Behind them, Homeowners of America Insurance Company, Auto Club Exchange, and Texas Farm Bureau Mutual Insurance Company each filed increases between 17.7% and 18%, adding a combined $185.6 million in calculated premium changes. No other state placed more than one filing in the top ten (S&P Global Market Intelligence).
This article examines why the concentration happened, how the file-and-use regulatory framework produces different actuarial pricing dynamics than prior-approval states, what the Q1 filings mean for Texas policyholders, and why the NAIC's nationwide homeowners data call, with its June 15 submission deadline, will produce the first standardized dataset to measure these regulatory disparities directly.
The Q1 2026 Filing Landscape: Carrier by Carrier
The S&P Global data ranks homeowners rate filings by calculated premium impact, the product of the percentage rate change and the carrier's in-force premium base in the affected state. This measure captures the financial magnitude of each filing better than percentage change alone. A 22.7% increase at a carrier with $877 million in Texas homeowners premium (Farmers) generates a larger dollar impact than a 30% increase at a carrier with $50 million in premium.
| Carrier | State | Rate Change | Calculated Premium Impact | Policyholders Affected |
|---|---|---|---|---|
| Allstate Vehicle & Property | Texas | +8.0% | $220.4M | ~852,000 |
| Farmers Insurance Co. of Texas | Texas | +22.7% | $199.2M | N/A |
| Homeowners of America Insurance | Texas | +17.7% | $68.6M | ~118,000 |
| Auto Club Exchange | Texas | +18.0% | $59.3M | N/A |
| Texas Farm Bureau Mutual | Texas | +18.0% | $57.7M | N/A |
Beyond the top five, the remaining Texas filings in the top ten included carriers spanning mutual, stock, and specialty lines. The only non-Texas entry in the top ten was a filing in another large-population state. The pattern is not that Texas carriers are uniquely aggressive; it is that the regulatory structure allows all carriers to act simultaneously and at speed.
Notably, the data also shows the system working in reverse. Porch Group Insurance Company of Texas filed a 14.8% rate decrease with a calculated premium impact of negative $26 million, affecting approximately 250,000 policyholders. That filing ranks as the third-largest homeowners rate decrease in the country in Q1. The same mechanism that enables rapid increases enables rapid decreases, a feature that prior-approval states structurally inhibit in both directions.
Why Texas: The File-and-Use Mechanism
Texas Insurance Code Chapter 2251 governs property and casualty rate filings. Under Texas's file-and-use framework, an insurer files its rates with TDI and can use them on the filing effective date. There is no waiting period for regulatory approval. The rates go live, and TDI reviews them after implementation. If TDI's actuarial staff determines that a filing does not comply with statutory standards, the department notifies the insurer and can initiate disapproval proceedings. But the rates remain in effect during the review process unless and until TDI takes formal action.
The statutory standards are straightforward. Rates must be based on sound actuarial principles, reasonably related to expected losses and expenses, and not excessive, meaning they must not produce unreasonably high long-term profit relative to the coverage provided. Rates also may not be inadequate to the point of threatening insurer solvency, and they cannot discriminate based on race, ethnicity, or national origin (Texas Insurance Code §2251.003).
In practice, TDI's actuarial staff reviews filings actively. In 2024, TDI examined 2,343 property and casualty rate filings and requested additional information on 77% of them. Of those filings, 2,037 were allowed to stand or approved, 174 were withdrawn by insurers (often after TDI raised questions), and 132 were rejected for technical noncompliance. Critically, zero filings were formally disapproved on actuarial grounds in 2024 (TDI Rate Review Report). TDI reports saving Texas consumers an average of $29.2 million annually through its regulatory review process, primarily by prompting carriers to withdraw or modify filings that could not withstand actuarial scrutiny.
The mechanism produces a specific dynamic: carriers file rate changes reflecting their current actuarial indications, implement those rates immediately, and then engage with TDI's review process after the fact. For carriers whose loss experience supports the filed rate, the post-filing review validates what is already in market. For carriers whose filings raise questions, TDI's leverage is the threat of formal disapproval, a process that can take months. The net effect is that rate changes reach policyholders faster in Texas than in any prior-approval jurisdiction.
File-and-Use vs. Prior Approval: The Actuarial Pricing Divergence
The distinction matters because the regulatory structure does not just affect timing; it shapes the actuarial pricing strategy itself. In a file-and-use state, the pricing actuary can set rates based on the most current loss indications and implement them within weeks. The feedback loop between loss emergence and rate response is tight. When catastrophe losses spike, as they did in Texas during the 2024 and 2025 severe convective storm seasons, carriers can adjust rates in the next filing cycle rather than waiting 6 to 18 months for regulatory approval.
Prior-approval states operate on a fundamentally different timeline. In California, the median approval time for homeowners rate filings reached 305 days in 2024. Colorado averaged 331 days. Rate increase requests above 7% in California can trigger a public hearing, adding months to the process. The California FAIR Plan filed for a 35.8% rate increase effective April 1, 2026; as of May 15, that filing remained under California Department of Insurance (CDI) review.
This creates distinct actuarial consequences. In prior-approval states, carriers must anticipate future loss trends when filing because the rate will not take effect for months or years. The filing includes a larger margin of uncertainty because the actuary is pricing into an unknown future regulatory timeline. If losses worsen during the review period, the approved rate may already be inadequate on the day it takes effect. If losses improve, the rate may be excessive. The regulatory lag introduces a structural mismatch between indicated rates and approved rates that compounds over time.
In file-and-use states, the mismatch is smaller because the gap between loss observation and rate implementation is shorter. But the trade-off is visible in the Q1 data: when multiple carriers update their rates simultaneously based on the same underlying loss trends (rising hail and wind severity, increasing replacement costs, higher reinsurance costs), the aggregate effect on policyholders is concentrated and sudden. Texas policyholders experienced the premium impact of nine of the ten largest national filings in a single quarter because the regulatory structure allowed all nine to hit the market at the same time.
Six states apply prior-approval regulation across all property and casualty lines: California, Hawaii, Mississippi, New York, North Dakota, and South Carolina. Most other states use some variant of file-and-use or use-and-file, though the specific mechanics vary. The Insurance Research Council has documented that less restrictive rate regulatory environments tend to show lower rate volatility over multi-year periods, because carriers can make smaller, more frequent adjustments rather than accumulating rate need and filing larger corrections after regulatory delays. The Q1 Texas data is consistent with this pattern: the individual percentage increases (8% to 22.7%) are large, but they reflect a market that was underpriced relative to loss experience over the prior two years, and the corrections are landing now because the system permitted them.
The Texas Market Context: Size, Concentration, and Catastrophe Exposure
Texas is the second-largest homeowners insurance market in the United States. The Texas Department of Insurance reports 8.23 million active homeowners policies and $19.75 billion in direct written premium as of 2025, representing roughly 11% of all homeowners premiums written nationally. The market is served by 157 insurance companies organized into 81 insurance groups (TDI Market Overview).
Market concentration amplifies the impact of individual filings. Three legacy carrier groups control approximately 75% of market share. State Farm leads with $3.77 billion in direct written premium and 19.1% market share. Allstate follows at $3.32 billion and 16.8%. USAA holds $2.22 billion and 11.2%. Farmers writes $1.61 billion at 8.15%, and Liberty Mutual holds $1.20 billion at 6.05% (TDI, 2024 data). When Allstate and Farmers, which together control roughly 25% of the market, file simultaneous increases, the dollar impact is outsized because their combined premium base exceeds $4.9 billion.
The underlying loss driver is severe convective storms. Texas sits at the epicenter of the national hail and wind corridor. Severe convective storms generated more than $52 billion in insured losses nationally in 2025, the third consecutive year above $50 billion (Triple-I). Texas absorbs a disproportionate share of those losses. Hail and wind claims account for the largest category of homeowners losses in the state, and the claims are not concentrated in a single event like a hurricane. They arrive through dozens of independent storm systems across the spring and summer convective season, creating persistent attritional severity that shows up in every carrier's actuarial indications simultaneously.
The premium trend reflects the loss trend. TDI data shows average statewide homeowners rate changes of 21.1% in 2023, 18.7% in 2024, and 4.3% in 2025. The deceleration in 2025 suggested that carriers were approaching rate adequacy after two years of aggressive corrections. But the Q1 2026 filings indicate that adequacy has not been uniformly achieved. Farmers' 22.7% increase, filed on top of the cumulative 2023-2025 adjustments, implies that the carrier's Texas book remained materially underpriced even after prior rounds of increases.
Average homeowners premiums in Texas now exceed $4,000 annually, roughly 60% above the national average of approximately $2,543. In high-exposure urban areas, the disparity is larger. Houston-area homeowners face average annual premiums approaching $6,000, driven by both convective storm frequency and elevated replacement costs in a market where construction labor remains constrained (Texas 2036, Insurify).
Allstate's $220 Million Filing in Operational Context
Allstate's Q1 Texas filing warrants closer examination because it intersects with the carrier's broader catastrophe exposure narrative. On April 16, 2026, Allstate disclosed $925 million in pretax catastrophe losses from March alone, driven by 15 separate wind and hail events. Three events accounted for 80% of the losses. First-quarter catastrophe losses totaled $1.24 billion pretax ($980 million after-tax), making Q1 2026 one of the costliest first quarters in the carrier's history (Allstate 8-K, April 16, 2026).
Despite those losses, Allstate's total policies in force grew to 38.576 million as of March 31, 2026, up 2.3% year-over-year. The carrier is not retreating from Texas; it is repricing the risk while expanding its book. The 8% Texas homeowners filing, affecting 852,000 policyholders, was effective for new business on January 26, 2026, and for renewals on March 12. This means the new rates were already in market before the March catastrophe losses materialized. The $220 million in additional annual premium that the filing generates is intended to cover the actuarial cost of losses like those March events, not respond to them retroactively.
This sequencing illustrates the file-and-use mechanism at work. Allstate's pricing actuaries filed rates based on their loss indications as of late 2025, those rates went into effect in January and March, and the carrier absorbed $1.24 billion in Q1 cat losses under the new rate level. Whether the 8% increase proves sufficient depends on whether 2026 severe convective storm losses stay within the actuarial projections embedded in the filing. If they do not, the file-and-use system will allow Allstate to file again.
Porch Group's Rate Decrease: The Other Direction
The Porch Group filing deserves attention precisely because it runs counter to the dominant trend. Porch Group Insurance Company of Texas filed a 14.8% rate decrease effective in Q1 2026, with a calculated premium impact of negative $26 million affecting approximately 250,000 policyholders. This was the third-largest homeowners rate decrease nationally in the quarter.
Porch Group operates a technology-driven insurance model through its Homeowners of America subsidiary and affiliated carriers. The company's underwriting approach relies heavily on property-specific data and predictive modeling, including roof condition, building materials, and proximity to fire stations, to segment risk more granularly than traditional carriers. When Porch Group's actuarial indications show improving loss ratios within its Texas book, the file-and-use system allows the carrier to pass that improvement to policyholders immediately rather than waiting for regulatory approval of a decrease.
The juxtaposition of Porch Group's decrease alongside Farmers' 22.7% increase within the same state and quarter illustrates a feature of file-and-use regulation that is easy to overlook. The system does not produce uniformly higher rates. It produces faster rate adjustments in both directions, driven by each carrier's individual loss experience and risk selection. Carriers with better-performing books decrease rates and attract new policyholders; carriers with deteriorating experience raise rates and shed volume. The competitive dynamics play out in real time rather than on the delayed timeline of prior-approval states.
Deductible Shifts and Coverage Erosion
Rate filings tell only part of the story. Alongside premium increases, Texas carriers have restructured policy terms in ways that transfer catastrophe exposure from insurers to policyholders. The most significant change is the near-universal adoption of percentage-based wind and hail deductibles.
In 2026, a 2% deductible is the dominant standard for wind and hail coverage across most of Texas. In hail-prone markets across North and Central Texas, some carriers have moved to 3% deductibles. On a $400,000 dwelling, a 2% deductible equals $8,000; a 3% deductible equals $12,000. The days when 1% or flat-dollar deductibles were widely available from major carriers are largely over in the state's most active hail markets (United Policyholders).
This shift means that the rate filings in the Q1 data understate the total cost transfer to policyholders. A carrier that raises rates 18% while simultaneously increasing the wind/hail deductible from 1% to 2% has effectively increased the policyholder's total cost exposure by more than the rate change alone implies. The NAIC's homeowners data call will capture deductible distributions for the first time across all participating jurisdictions, providing actuaries and regulators with the data necessary to quantify this coverage erosion.
The Texas FAIR Plan and Market of Last Resort Growth
As private market rates rise, the state's residual market has expanded. The Texas FAIR Plan Association, which provides basic property coverage to homeowners unable to obtain insurance in the voluntary market, saw its applicant base grow from 66,512 in 2021 to 121,658 in Q1 2025, an 83% increase in four years. The Texas Windstorm Insurance Association (TWIA), which provides wind and hail coverage along the Gulf Coast, reported over 280,000 policies with $121 billion in total insured value as of 2025 (TDI FAIR Plan Overview, Capstone DC).
FAIR plan growth is a leading indicator of market stress. When voluntary carriers raise rates aggressively, as the Q1 data shows, some policyholders cannot afford the new premiums and move to the residual market. Others are non-renewed by carriers tightening their underwriting. TDI data shows that the non-renewal rate in Texas homeowners nearly doubled from 0.46% in 2020 to 0.83% in 2023. Senate Bill 1006, proposed during the 2025 legislative session, would have required carriers to report quarterly on policy declinations, cancellations, and non-renewals. The bill stalled in the House committee, but its advancement signaled legislative awareness of market tightening (Texas Legislature, 89th Session).
Legislative Response: SB 1643 and the Prior-Approval Debate
The concentration of rate increases in Texas has drawn political attention. Senate Bill 1643, introduced in the 2025 session, would have required TDI to grant prior approval for any homeowners rate increase exceeding 10%. Had it passed, the bill would have fundamentally altered the regulatory structure by introducing a prior-approval threshold into the file-and-use framework. Carriers would retain the ability to file and immediately use increases up to 10%, but any increase above that level would require TDI sign-off before taking effect.
The bill stalled, but the policy debate it represents is directly relevant to the Q1 data. If SB 1643 had been law, Farmers' 22.7% increase, Homeowners of America's 17.7% increase, Auto Club Exchange's 18% increase, and Texas Farm Bureau's 18% increase all would have required prior approval. Only Allstate's 8% filing would have cleared the threshold automatically. The bill would not have prevented the rate increases; it would have delayed them, introducing the same regulatory lag that characterizes California and New York while preserving the file-and-use mechanism for smaller adjustments.
The actuarial trade-offs are real. Prior approval would give regulators more control over the pace of increases, reducing premium shock for policyholders. But it would also delay rate adequacy for carriers, potentially worsening solvency risk during periods of rapidly escalating catastrophe losses. Texas carriers already operate in a market where the five-year average loss ratio (2020-2024) was 69.8% and the combined ratio in 2024 was 98.3% (TDI). Delaying rate corrections in a market this close to break-even could push carriers into unprofitability, trigger credit downgrades, and accelerate voluntary market exits, precisely the outcomes that rate increases are designed to prevent.
The NAIC Data Call: Regulatory Visibility Arrives June 15
The NAIC's Homeowners Market Data Call, with its June 15, 2026 submission deadline, will produce the first standardized dataset capable of measuring the regulatory disparities that the Q1 Texas filing data illustrates. The data call requires every carrier writing at least $50,000 in homeowners premium in any of 50 participating jurisdictions to submit eight years (2018-2025) of zip-code-level data on premiums, claims by peril, deductible structures, non-renewals, and mitigation discounts.
For the file-and-use question specifically, the data call enables a comparison that has never been possible with standardized data. Regulators will be able to compare year-over-year premium changes, loss ratios, and non-renewal rates across file-and-use states (Texas, Florida, Georgia) and prior-approval states (California, New York) using identical data fields and reporting periods. The eight-year window captures the full cycle from pre-pandemic baseline through post-pandemic inflation and climate-driven catastrophe acceleration. If prior-approval states show slower rate adjustment but higher loss ratio volatility, or if file-and-use states show faster correction but larger single-year premium shocks, the data will make those patterns quantifiable for the first time.
The NAIC's Homeowners Market Data Call (C) Task Force finalized submission requirements at the Spring 2026 National Meeting on March 24. The formal data call letter was issued in late March, giving carriers approximately 82 days to compile and submit data across 113 fields. No extensions will be granted. Automated validation checks at the NAIC's Regulatory Data Collection portal reject submissions that fail formatting or consistency rules (NAIC, Insurance Journal).
Why This Matters for Actuarial Practice
Pricing actuaries in file-and-use states should recognize that the Q1 Texas data confirms what loss indications have been signaling: the market is still correcting. Carriers that have not filed since 2024 may be accumulating rate need that will require larger corrections when they do file. Smaller, more frequent filings reduce premium shock and political risk relative to large single-year adjustments.
Actuaries working on catastrophe modeling and reinsurance placement should note the compounding severity trends in Texas severe convective storm losses. Allstate's $1.24 billion Q1 catastrophe losses, driven predominantly by wind and hail, reinforce the case that secondary perils require the same modeling rigor historically reserved for named storms. Reinsurance treaties covering Texas homeowners books will price off these loss trends.
Regulatory actuaries and consultants advising state departments of insurance should prepare for the NAIC data call to shift the information balance. When regulators can benchmark Texas rate filings against loss experience data from all 50 jurisdictions, the file-and-use review process gains an empirical tool it has never had. TDI's actuarial staff currently reviews each filing against the individual carrier's submitted data. The NAIC data call will add a cross-carrier, cross-state comparison layer.
Actuaries involved in legislative analysis should anticipate that the SB 1643 prior-approval debate will return, both in Texas and in other file-and-use states experiencing similar concentration effects. The actuarial profession's input on the trade-offs between rate-filing speed, solvency protection, and consumer premium shock will be essential. ASOP No. 29 (Expense Provisions in Property/Casualty Insurance Ratemaking) and ASOP No. 53 (Estimating Future Costs for Prospective Property/Casualty Risk Transfer and Risk Retention) provide the professional framework for evaluating these trade-offs.
The Q1 2026 data makes visible what the regulatory structure has always produced: faster rate adjustments in both directions, concentrated in the states that allow them. Whether that concentration serves policyholders better or worse than the regulated delays of prior-approval states depends on the time horizon. In the short term, the premium shock is real. Over the long term, the actuarial question is whether faster correction prevents the solvency crises and market withdrawals that regulatory delay can cause. The NAIC data call will, for the first time, provide the data to answer that question empirically.
