Allstate’s pre-tax cat loss for current aggregate year reaches $2.387bn after August

Large US insurance firm Allstate has announced an estimated pre-tax catastrophe loss burden for the month of August 2025 of $213 million, which has lifted the total for the current annual aggregate risk period for its catastrophe bonds to $2.387 billion so far.

Allstate had estimated $594 million of pre-tax catastrophe losses for April 2025, then a further $777 million for May, an additional $619 million pre-tax for June, and then a further $184 million for July.

However, for August, Allstate has reported $213 million of catastrophe losses for the month pre-tax, or $168 million after-tax,.

So far, Allstate’s estimated total cat losses for the third quarter of 2025 have reached $397 million, or $313 million after-tax.

Allstate reports major catastrophe losses

Allstate Corp. reported an estimated $213 million in pretax catastrophe losses for August, driven by 10 separate events. Three wind-and-hail storms accounted for roughly 70% of the total.

The August figure was, however, lower than the same month in 2024, when Allstate booked $272 million in pretax catastrophe losses from 15 events, including a severe hailstorm in Calgary, Alberta.

For the first two months of the third quarter, Allstate’s pretax catastrophe losses are estimated at $397 million, about half of the comparable year-earlier total. The difference reflects the absence of a landfalling hurricane so far in the season, according to earlier disclosures.

The reduced catastrophe losses compared with 2024 could provide short-term relief to Allstate's underwriting results in the third quarter. Lower claims costs may also help offset higher reinsurance pricing that has weighed on carriers across the industry.
