Flood Reassessment Reshapes Property Pricing Assumptions
The September 2024 flooding across Lower Silesia and the Klodzko valley produced concentrated losses in towns whose risk maps had not been revisited in years. Carriers had priced flood exposure off historical return periods that the event comprehensively invalidated, and the reserving that followed was uncomfortable for several participants. Property pricing has since moved toward catchment-level assessment rather than postcode banding, and reinsurance treaties repriced at the following renewal. Sums insured are also rising because rebuild costs climbed faster than the policy schedules tracking them did. The maps themselves had not been revisited in a generation.
