From hurricanes in the North Atlantic Ocean, to typhoons in the Northwest Pacific Ocean, to cyclones in the Southwest Pacific Ocean and Indian Ocean, to winter storms in Europe, windstorms can have a devastating effect on businesses.
Based on AGCS analysis of more than 470,000 insurance industry claims from over 200 countries around the world over the past five years, activity ranks as the fourth top cause of loss for businesses overall behind fire/explosion incidents, plane crashes and faulty workmanship/maintenance issues. It is the only natural catastrophe event to appear in the top 10 causes of financial losses for businesses (see graphic) the analysis shows.
Furthermore, storm activity is the second more frequent cause of business interruption loss (again behind fire and explosion incidents), accounting for one in five business interruption claims. Indeed, the business interruption costs arising from a storm can often significantly outweigh the costs of any property damage. AGCS insurance industry claims analysis shows that even the average BI loss from a windstorm event for businesses costs €3.8mn ($4.4mn) compared to around €2mn ($2.26mn) for the average direct property loss.
With the advent of just-in-time management philosophies and lean inventories, losses caused by windstorms can cripple an organization. Property damage and business interruption may be covered by the insurance policy, but the loss of market share and a damaged reputation cannot be easily recovered.
Based on AGCS’ experience over the past 20 years, windstorms appear to be increasing in frequency and intensity. Certainly the population growth and expansion of industries, particularly in the developing world, will ensure that losses from windstorms will continue to increase in the future. Obviously, windstorms cannot be prevented from occurring. However, loss can be greatly minimized by adequate preparation before the storm arrives, including the development and implementation of a comprehensive written windstorm emergency plan.
