Natural catastrophes in 2023: gearing up for today’s and tomorrow’s weather risks

A devastating earthquake in Turkey and Syria, severe convective storms (SCS) and large-scale urban floods were the main events driving insured natural catastrophe losses to USD 108 billion in 2023, reaffirming the 5–7% annual growth trend in global insured natural catastrophe losses since 1994. Swiss Re Institute estimates that insured losses could double within the next ten years as temperatures rise and extreme weather events become more frequent and intense. Therefore, mitigation and adaptation measures are key to reduce natural catastrophe risk. Global insured losses from natural catastrophes outpaced global economic growth over the past 30 years: From 1994 to 2023, inflation-adjusted insured losses from natural catastrophes averaged 5.9% per year, while global GDP grew by 2.7%. In other words, over the last 30 years, the relative loss burden compared to GDP has doubled.
