Impact verdict
Medium impact. Extreme heat events across multiple major western European economies can generate significant insured losses through wildfire ignition, energy infrastructure stress, agricultural damage and excess mortality claims, though the event is still in forecast phase and actual loss crystallisation is uncertain.
