The world’s financial institutions have been urged to collaborate to tackle the rising costs of natural perils and the burgeoning size of the insurance gap.

Speaking as broker Gallagher Re issued its 2022 Natural Catastrophe Report its chief science officer said the growing interconnection of climate change and its impact made the need for identification and mitigation ever more urgent.

The report highlighted the global need to ramp up natural hazard mitigation and climate adaptation efforts, against a backdrop of  the increasing severity and frequency of annual catastrophe losses.

“Another year of complex natural hazard events in 2022 resulted in a direct economic cost of $360 billion,” it added. “The insurance industry covered $140 billon of this total, marking the fifth year since 2017 to cross the $100 billion threshold for insurers.”

The year featured another series of costly, consequential, and record-setting natural catastrophe events around the world that again brought into focus the need to better account for the growing risks these hazards bring the report added. Insurance plays an important role in the aftermath of events, with private insurers covering $125 billion of losses and public insurance entities covering another $15 billion.

Steve Bowen, chief science officer at Gallagher Re, explained: “The financial cost of natural hazards continues to increase, and we are further recognising that a consistently high global protection gap, 61% in 2022, means that much more opportunity exists to help people prepare before and after a disaster occurs. As catastrophe losses grow more expensive, we again look to the connected nature of climate change, exposure growth, and social inflation as important issues enhancing eventual loss costs. The increase in severity, and in some cases the frequency of “secondary” peril events, presents (re)insurers with a multi-faceted and complicated challenge when it comes to risk protection and mitigation.”

He added: “How we collectively bring together financial institutions (insurance, asset managers, real estate, banking), governmental entities, academia, and emergency management to identify risk will be critical as we implement actionable plans to improve our resilience, mitigation and adaptation-readiness. Such action will result in favourable impacts when trying to slow the rate of annual catastrophe loss growth.”

The report said the US endured several large-scale and impactful events in 2022, led by Hurricane Ian. The storm was poised to result in a minimal $55 billion loss for public and private insurance entities, and an overall economic loss of $112 billion in the US alone. This marked one of the costliest natural disaster events ever recorded globally. The country also endured a prolific drought that resulted in $9 billion in crop insurance indemnity payouts. Three severe convective storm (SCS) outbreaks resulted in a multi-billion-dollar insured loss alone. This aided in 2022 becoming the 15th consecutive year with aggregate insured SCS losses topping $10 billion and the 8th year since 2010 that such losses have topped $20 billion.

Outside the US, the costliest event and one of the most consequential from a humanitarian perspective was the prolific seasonal monsoon flooding in Pakistan. A report from the World Bank estimated $15 billion direct physical damage economic loss, while the country’s National Disaster Management Authority cited 1,739 fatalities, 2.3 million homes damaged, and 33 million people affected across 90 districts.

Historic flooding also impacted several regions of Africa, notably in Nigeria and South Africa, where each country’s insurance industry faced ones of its costliest natural catastrophe events on record. The effects of a third consecutive La Niña brought record-setting rainfall to parts of Eastern Australia. The Insurance Council of Australia stated weather-related events had resulted in nearly $5 billion in payouts, with the bulk coming from a historic flood event in late February and March.

Other notable global events in 2022 included: a series of record summer heatwaves in Europe that led to excess mortality totals into the tens of thousands; a powerful March offshore earthquake in Japan; record-setting SCS activity in France; extensive drought conditions across South America, Europe, and parts of Asia; typhoon landfalls in Japan and the Philippines; Hurricane Fiona landfalls in Puerto Rico and Canada; multiple strong European windstorm vents to wrap the 2021-2022 season; and, an intense May derecho in Canada.

Bowen concluded: “The fingerprints of climate change were visible on virtually every major weather and climate event in 2022, once again highlighting the urgency to implement proper planning and investment strategies that will limit the risk to life and property. The implications of climate change on daily weather and climate events continues to be more evident and better understood. While we are still trying to account for uncertainties that exist in how climate change may influence events on a regional and per peril basis, it is clear that impacts from the phenomenon are not future tense. They are already being felt today.”
