Natural CatastrophePropertyMarine CargoEnergyCasualty & Liability
A strengthening El Niño in the Pacific is forecast to elevate global extreme weather risk through the coming season, including severe storms, heavy rain, drought, and wildfires. For the London market, this is a forward-looking natural catastrophe signal affecting multiple property and energy lines, pending the materialisation of named loss events.

Impact verdict
Medium impact. El Niño intensification is a recognised precursor to elevated natural catastrophe activity (Atlantic hurricane frequency, Pacific typhoon activity, US severe weather, Australian/Asian bushfire risk, drought in grain belts). Source explicitly forecasts hurricanes, heavy rain, drought, and wildfires linked to the strengthening event. No specific insured assets, named events, or loss estimates are available — this remains a forward-looking climate signal. Insured loss magnitude is contingent on subsequent named events materialising; potential impact is therefore medium rather than high until landfall/loss evidence emerges.
