Swiss hailstorm bill climbs into the hundreds of millions

Insurers expect the August 28 storm to produce losses in the three-digit million-franc range. The hailstorm, the most damaging of the year according to several non-life insurers, struck populated parts of Switzerland with enough force to overwhelm claims teams and repair networks within days.

An AWP survey cited by Swissinfo.ch found that the combined bill is expected to reach at least the three-digit million range. No final national total is available yet. Claims continue to arrive, and insurers say they will need more time to assess damaged homes, gardens, cellars and vehicles.

Mobiliar had logged around 18,000 claims by Wednesday, September 2, including 14,300 involving vehicles. Allianz Suisse reported more than 11,000 vehicle claims, while Helvetia had received around 11,500 claims. These figures come from individual insurers and cannot be added together because their customer portfolios overlap only in part and cover different risks.

The financial impact reaches beyond insurers. Households face deductibles, disrupted travel and repair bills. Car owners may wait weeks for inspections or replacement vehicles. Garages and rental companies are dealing with a sudden concentration of demand across the Bernese Mittelland and other affected areas.

Mobiliar alone counted 14,300 damaged vehicles among its first 18,000 claims. The concentration of motor claims shows how quickly hail can turn a weather event into a mass consumer problem. Thousands of cars may require bodywork, replacement windscreens, roof repairs or a full expert assessment.

Allianz Suisse said it had recorded more than 11,000 vehicle claims, and Helvetia said roughly 90% of its 11,500 claims came from motor-vehicle owners. Generali Switzerland also reported a rise in claims, although it said the number of cases and the financial impact remained impossible to assess definitively.

Insurers are responding with drive-through centres where roadworthy cars can be inspected without a conventional workshop appointment. Allianz Suisse is arranging collection and expert assessment for vehicles suspected of being total write-offs. Those assessments will determine whether repairs make economic sense or whether the vehicle must be written off.

The process can leave owners without transport. Helvetia and Allianz Suisse are offering financial support for public transport when a replacement car is unavailable. Helvetia warned that rental companies and garages do not have enough vehicles to meet the surge in demand, creating a second bottleneck after the storm itself.

Mobiliar expects its own storm losses to reach the high double-digit millions. Allianz Suisse gave a similar initial assessment, saying its total claim amount would be at least in the high double-digit millions. Those estimates cover more than crumpled car panels. Insurers are also processing claims for property damage, including affected cellars and gardens.

The national figure will depend on the number of late claims, the proportion of total write-offs and the cost of repairing buildings and household contents. Insurers have cautioned that a reliable projection may not be possible until the end of the week at the earliest, while Helvetia expects more claims to arrive over the following days and weeks.

Axa declined to provide figures but described the scale of the damage in parts of the densely populated Bern region of the Mittelland as exceptional. That concentration matters for insurers. A storm that hits a large number of policyholders in a compact area can generate a heavy claims load in a matter of hours, even when individual losses vary widely.

For households, the final cost depends on policy terms, deductibles and whether damage falls under motor, building or household insurance. Owners should document damage promptly and follow their insurer's reporting instructions before arranging major repairs.
