The rising frequency and severity of catastrophic events is also contributing to the growth of the excess liability insurance market. Catastrophic events, including floods, wildfires, and hurricanes, are becoming more common due to climate change, which disrupts weather patterns and increases global temperatures. Excess liability insurance offers additional financial protection beyond primary policies, covering high-cost claims resulting from severe damage, injury, or legal liability. For instance, in January 2024, the US National Centers for Environmental Information (NCEI) reported that 2023 set a record with 28 separate weather and climate disasters, each causing at least $1 billion in damages, the highest number recorded in a single year. This rise in catastrophic events is driving the market for excess liability insurance.
