Verisk Q1 2026: Property Claims Fall 8.9% as Severity Climbs Toward a Record

U.S. property claim volume fell 8.9% year over year in Q1 2026, yet severity is not following frequency downward: Verisk's maturation-adjusted estimate puts average replacement cost value near $17,687, enough to keep 2026 on a near-record annual severity track, as ACV-only settlement provisions suppress claim counts without proportionally shrinking the losses that do get filed (Verisk Property and Restoration Solutions, July 2026).

A Quarter That Looks Quiet and Isn't

Verisk's Q1 2026 Quarterly Property Report puts U.S. claim volume 8.9% below Q1 2025 and 13.13% below the trailing five-year average (Verisk, July 2026). On its face, that reads as a genuinely benign quarter. It was not a quiet one. Winter Storms Fern and Hernando produced more than 46,000 ice, snow, and collapse claims across the eastern U.S. and an estimated $478 million in replacement cost value, reaching an 83% completion rate by the report's publication date (Verisk, via Risk & Insurance, July 2, 2026). A March Kona low pressure system drove claims on Oahu up more than 1,900% year over year, generating over 2,000 claims and roughly $14 million in estimated replacement cost value, a scale of loss activity Hawaii almost never registers in national property data. Texas, Ohio, and California accounted for roughly a quarter of all Q1 claims between them, while several western states saw sharp increases: Alaska claims rose 121% and Arizona 78% year over year (Verisk, via Claims Journal, July 2, 2026). Florida moved the opposite direction, down 65.7%.

A quarter with a historic Hawaii event, a 121% claim spike in Alaska, and a multi-state ice storm producing $478 million in losses is not the profile of an insurance environment where underlying property risk quietly improved. Verisk's own explanation for the gap is explicit: a meaningful share of the volume decline reflects policy-language changes, principally the wider use of actual cash value-only loss settlement provisions, rather than fewer genuine losses. Susan Fleming, Verisk's vice president of business intelligence and insights, put it directly: "We're really starting to see increased usage across the board of those ACV-only loss provisions and loss settlements and endorsements than we have in the past" (Claims Journal, July 2, 2026). That single sentence is the hinge the rest of this report turns on, and it is worth working through the mechanism before trusting the headline decline as a frequency trend input.

The ACV Confound: Why Falling Claim Counts Don't Mean Falling Risk

An actual-cash-value-only settlement provision pays the depreciated value of damaged property rather than the cost to replace it new. That structural change alters homeowner filing behavior at the low end of the severity distribution well before it changes anything about the underlying hazard. Consider an aging roof with a wear-related leak, or a slow-developing water intrusion claim where the repair cost is a few thousand dollars. Under a replacement-cost policy, the insured files because the payout roughly covers the fix. Under an ACV-only provision, the same claim nets a depreciated payout that may fall well short of the repair bill, so the homeowner often does not bother filing at all. The loss event still occurred. The property is still deteriorating. The claim simply never enters the insurer's data.

This matters for a ratemaking actuary because it is a truncation of the loss distribution, not a shift in it. ACV-only provisions do not reduce the probability or severity of underlying property damage; they raise the effective deductible on small and moderate claims by stripping out depreciation credit, which pushes the filing threshold upward. Claims below that new threshold disappear from the count. Claims above it, the larger, more complex, catastrophe-driven losses where the ACV payout still clears the homeowner's cost to act, keep getting filed largely unchanged. The mechanical result is a frequency count that falls even when nothing about the underlying peril improved, paired with a surviving claim population that skews toward the higher end of the severity distribution because the cheap claims were filtered out first. That is precisely the shape of Q1 2026's data: an 8.9% drop in claim counts arriving in the same quarter that Verisk's own maturation-adjusted severity estimate is heading toward a near-record high.

The confound cuts two ways depending on peril. Water claims, the largest single category at 31.1% of Q1 volume and up on an annual basis, are exactly the loss type most exposed to ACV-driven suppression, since gradual leaks and wear-related intrusion sit right at the margin where depreciation determines whether filing is worthwhile. Large-scale catastrophe perils behave differently, which is the nuance the next section works through.

The Maturation Math: A Live Case Reserve Development Example

Verisk reports Q1 2026's average replacement cost value at $16,079 as currently booked, but its own maturation model projects that figure will climb to approximately $17,687 once claims finish developing, a 10% gap between the immature and the matured estimate (Verisk, July 2026). That would not outrank the already-matured Q4 2025 severity figure, but it would keep 2026 on pace for the second-highest annual average severity after 2025 if later quarters follow the same pattern. It is also, for any actuary who works with loss triangles, a clean worked example of exactly the phenomenon a case reserve development factor is built to capture: early-notice reserves are set before investigation, appraisal, and remediation costs are finalized, and they mature upward as those costs firm up. Verisk's Q4 2025 figure shows the same pattern in the prior quarter, climbing to a final matured value of $18,910 (Verisk, July 2026). Two consecutive quarters developing upward by a similar order of magnitude is not noise; it is a development pattern an actuary would expect to see reflected in the loss development factors selected for the current accident quarter, not just applied retrospectively once the data has already matured.

The practical risk is treating the $16,079 figure as though it were a finished number. A reserving actuary who anchors a current-quarter severity trend to the immature reported value, without applying a maturation adjustment consistent with the 10% development Verisk itself is projecting, will understate the accident quarter's ultimate cost by roughly the same margin. That is a familiar IBNER problem dressed in new data: incurred-but-not-reported development gets attention, but incurred-but-not-enough-reported development on claims already on the books is the mechanism actually at work here, and it is large enough in this instance to move the headline severity figure by more than $1,600 per claim.

Reconstruction Costs Decelerate While Severity Doesn't: A Mix Problem, Not a Unit-Cost Problem

If maturation-adjusted severity is climbing toward a near-record high, the natural first suspect is unit-cost inflation in materials and labor. The data does not support that explanation. Verisk's reconstruction cost index rose 3.4% year over year through March 2026, a deceleration from 5.3% growth the prior year (Verisk, July 2026). Unit reconstruction costs are cooling. Maturation-adjusted claim severity is not. That divergence rules out broad-based rebuilding cost inflation as the primary driver of the severity trend, which points the explanation back toward claim mix and complexity rather than the price of lumber and labor.

The component-level data underneath the 3.4% headline shows why a blended index can mask sharply divergent subcomponents. Concrete masons' labor costs rose 15.39% year over year in the U.S., and fuel costs, which flow into every delivery and equipment charge on a reconstruction job, jumped 42.70%. Lumber, by contrast, fell 2.32% over the same period. A composite index that nets a 42.70% fuel spike against a 2.32% lumber decline and several moderate line items lands at a deceptively calm 3.4%, even though individual carriers writing claims with heavy fuel or masonry components are seeing costs run well above the headline.

With unit-cost inflation decelerating, the remaining explanation for climbing maturation-adjusted severity is mix: the population of claims actually being filed and paid is shifting toward more complex, higher-cost losses, exactly the population the ACV confound predicts should survive the filtering effect. Fewer cheap claims plus a stable or richer mix of expensive ones produces rising average severity without any change in the underlying cost of a board foot of lumber or an hour of masonry labor.

Water, Ice, and a Hail Signal That Cuts Against the Confound

Not every loss-type movement in the Q1 2026 data fits the ACV story cleanly, which is itself useful for an actuary trying to separate a genuine hazard signal from a policy-language artifact. Water claims led all loss types at 31.1% of volume, consistent with the confound: water losses are disproportionately exposed to ACV-driven non-filing at the low end. Ice and snow claims surged 188.7% year over year, a straightforward hazard signal tied directly to Winter Storms Fern and Hernando's path across the eastern U.S. rather than anything to do with settlement provisions.

Hail is the more interesting case. Total hail claim counts fell 23.6% year over year, which on its own could be read as either a genuine reduction in large-hail storm activity or further evidence of ACV suppression. Verisk's own Respond data resolves the ambiguity: residential roofs struck by hail in the 1 to 1.99-inch range fell only 10%, while roofs struck by hail of 2 inches or larger fell 59%. If ACV-only provisions were the dominant driver of the hail decline, the effect should concentrate in the smaller, marginal-filing hail claims, the ones where a depreciated payout might not clear the homeowner's repair threshold. Instead, the decline concentrated in the largest, most severe hail claims, the ones virtually certain to clear any ACV threshold regardless of depreciation. That pattern points to a genuine reduction in large-hail storm frequency this quarter rather than a settlement-provision artifact, and it is a useful reminder that not every frequency decline in this report has the same cause. Some of the volume drop is real hazard variation. Some of it is policy language. Disentangling the two, loss type by loss type, is the actual analytical task the report sets up.

Why This Matters: The Frequency Trend Selection Risk

The reserving and ratemaking implication follows directly from the mechanism above. A pricing actuary who selects a frequency trend for homeowners or commercial property off the raw 8.9% year-over-year claim count decline, without separating the portion attributable to ACV-provision mix shift from the portion attributable to genuinely improving loss experience, will build a rate filing on a trend that partially reflects a one-time policy-form change rather than a repeatable improvement in loss cost. Once ACV-only endorsement penetration stabilizes across the book, the mechanical suppression effect stops accruing further year-over-year declines. A frequency trend calibrated to the current rate of decline would then overstate future improvement and understate the loss cost the book will actually generate once the mix shift is fully absorbed.

The fix is a segmentation problem before it is a trend-selection problem. Actuaries building frequency assumptions off this kind of data should track ACV-only endorsement penetration explicitly as a rated or at least monitored policy characteristic, separate claim experience into ACV-only and replacement-cost cohorts where the data supports it, and treat the raw aggregate frequency trend as contaminated by a level shift rather than a clean signal of improving risk. The same logic applies on the reserving side: if the claims that do survive the ACV filter skew toward the more complex, higher-severity end of the distribution, as this quarter's data suggests, the population feeding loss development triangles is itself shifting in composition, which can distort loss development factor selection if the historical triangle was built on a different, less-filtered claim mix. A carrier that files rates or sets reserves off the naive frequency decline is pricing and reserving for a version of 2026 that assumes the ACV effect is permanent improvement rather than a mix shift that will stop generating further apparent gains once it saturates the book.
