Natural catastrophes in 2021 resulted in a total global economic loss of USD 270 billion and insured losses of USD 111 billion, according to Swiss Re Institute. This continues the long-term trend of insured losses increasing by an average of 5-7 percent annually worldwide.
While Hurricane Ida was the costliest single natural disaster in 2021, secondary peril events once again accounted for the majority of insured losses from natural catastrophes over the year. The flooding in Europe in July, for example, was the costliest natural disaster on record in the region. Despite record-level insured losses from floods, the associated global protection gap remains large.
“Floods affect nearly a third of the world population, more than any other peril. In 2021 alone, we witnessed more than 50 severe flood events across the world,” said Martin Bertogg, Head of Catastrophe Perils at Swiss Re. “Given the scale of devastation, flood risk deserves the same attention and risk assessment rigour as primary perils such as hurricanes.”
Flood losses will keep increasing with climate change and urbanisation
Climate change is anticipated to cause more frequent and more extreme weather events says Swiss Re Institute. Growing populations, rapid urban development and the accumulation of economic wealth in disaster-prone areas are contributing to the ever-growing catastrophe losses. 2021 was another year of intense natural catastrophe activity, including devastating floods in Europe, China, the US, and other parts of the world. Already in the first quarter of 2022, major flooding in eastern Australia has caused widespread devastation and substantial insured losses.
“Growing losses from floods are becoming ever more apparent,” said Jérôme Jean Haegeli, Swiss Re's Group Chief Economist. “Last year we had another wake-up call. There is a growing urgency for action to increase the resilience of societies worldwide. Together with the public sector, re/insurers are well equipped to steer development away from high-risk areas and invest in protective measures such as green infrastructure. This keeps assets insurable while also improving the growth outlook.”
Swiss Re Institute sigma records show that flooding is by far the most frequently occurring natural peril. In the past decade, there were approximately three times as many major flood events as tropical cyclones. Floods were also causing more than a third of all fatalities related to natural catastrophes. Economic losses from floods amounted to 23 percent, the second highest after tropical cyclones. Yet Swiss Re Institute finds that over the past decade, only 5 percent of severe flood losses were insured in emerging markets and 34 percent in advanced economies, indicating a large global protection gap. The largest gap in flood protection is in Asia, with only 7 percent of economic losses being covered by insurance. By contrast, in Europe 34 percent of flood losses are insured.
