Insured losses from natural disasters rise by 50%

Open-access content Tuesday 30th March 2021
Insured losses from natural disasters rise by 50%

Global insured losses from wildfires, flooding and other natural disasters increased by 50% last year amid ongoing climate change and urbanisation, Swiss Re has revealed.

The reinsurance company's latest sigma research, published today, shows that natural catastrophes caused global economic losses of $190bn (£139bn) last year, with the insurance industry covering $81bn.

This is up from the $54bn of insured losses recorded in 2019, while manmade disasters cost insurers an additional $8bn, bringing total global insured losses to $89bn in 2020 – the fifth-costliest year on sigma records since 1970.

Secondary perils – which generate small to mid-sized losses – accounted for 71% of natural catastrophe insured losses, resulting mostly from severe convective storms and wildfires in the US and Australia. 

Swiss Re explained how there has been a rise in losses from secondary perils in recent years, suggesting that future peak losses could be as high as $300bn, mainly due to population growth, value accumulation in highly-exposed areas and climate change.

“Climate change is already becoming visible in more frequent occurrences of secondary perils, such as flash floods, droughts and forest fires,” said Jérôme Haegeli, Swiss Re group chief economist. “Natural disaster risks are increasing and climate change will significantly exacerbate them. 

“This underlines the urgency to better protect our communities against catastrophic losses while dramatically reducing carbon emissions. Unless mitigating measures are taken, such as greening the global economic recovery, the cost to society will increase in the future.”

A record number of 30 named storms caused insured losses of $21bn during the North Atlantic hurricane season last year, with 12 US storms making landfall in areas of low population density and exposure.

Swiss Re described this as a "lucky escape", explaining how losses would have been much higher if storm occurrence patterns had been less favourable.

The firm urged reinsurers to do more to help people, businesses and societies become more resilient, highlighting how the need to close protection gaps persists for both primary and secondary perils.

Martin Bertogg, Swiss Re's head of catastrophe perils, added: “Given the dynamic nature of risks, reinsurers' risk models need to increasingly consider forward-looking risk trends, such as climate change, urbanisation and socio-economic inflation – rather than relying on historical data observations – when assessing the potential magnitude of losses.”
