El Nino impact on insurers reassessed

The periodic El Nino climate phenomenon has traditionally lowered the risk of costly Atlantic hurricanes, but decades of population growth along U.S. coastal areas and rising property values are forcing insurers to rethink that assumption. U.S. government scientists said El Nino arrived in June 2026, expecting a below-average hurricane season of eight to 14 named storms. However, coastal development has increased property exposure, with population in coastal counties rising by over 40 million since 1970, and home values and reconstruction costs rising over 70% and 60% respectively in the past decade. Insurers are now focusing less on storm count and more on landfall location and property value. A major hurricane strike on Miami, Tampa, or Houston could cause insured losses exceeding $100 billion, according to Karen Clark & Company. Insurers are developing more sophisticated catastrophe models incorporating climate signals and property-level data, and embracing AI to improve risk modeling.
