Insured flood losses double to $117 billion in last decade: Swiss Re
5 September 2022
Swiss Re says insured losses from floods doubled to $US80 billion ($117 billion) in the 2011-2020 period from the previous decade, highlighting the need to do more to address the risk.
Last year flood losses reached $US20 billion and only 18% of the economic damage were insured, a new report says.
The report says increased wealth, larger populations and urbanisation have raised flood risk exposures across the world.
“In addition, an effect of climate change is increasing likelihood of high-intensity, heavy rain and short-duration floods events associated with tropical cyclones,” Swiss Re says.
“Severe rainfall and flooding events – including in South Africa, South Korea, Australia, the US and Europe – have caused widespread devastation, affecting homes and businesses also outside typical floodplain areas this year.
“In the past month, storms and torrential rains in Pakistan have caused extensive and deadly flooding.”
Swiss Re says better data and sophisticated risk mapping and modelling are enabling more accurate quantification of flood risk, creating scope for growth of the private sector flood insurance market.
“These models, which incorporate detailed hazard, vulnerability and asset value data enable insurers to rate individual exposures according to unique characteristics, although a range of uncertainty in model outputs remains,” Swiss Re says.
“The insurance industry needs to invest more in modelling and risk awareness-raising initiatives to help close the protection gap.”
