Severe thunderstorms, mainly in the US, accounted for 70% of global insured losses.</span></p> <p><span>Balz Grollimund, Head of Catastrophe Perils at Swiss Re, said: "In recent years, severe thunderstorms have emerged as a main driver of a significant increase in insured losses. This is due to growing populations and higher property values in urban areas, along with insured property being more vulnerable to hail damage. Therefore, multi-billion-dollar loss events from this peril are likely to become more common."</span></p> <p><span>Thunderstorms or severe convective storms (SCS) are characterised by strong winds including tornadoes, hail and heavy rain. In total, these led to insured losses of USD</span><span> </span><span>42</span><span> </span><span>billion globally in the first half of 2024. In the US, 12 storms each caused losses of USD</span><span> </span><span>1</span><span> </span><span>billion or more, demonstrating the loss potential of this peril. According to Swiss Re Institut</span>e's <a href="http://www.swissre.com/institute/research/sigma-research/sigma-2024-01.html" style="text-decoration: none;">sigma 1/2024</a>, i<span>nsured losses from SCS in the US have increased by around 8% in nominal terms annually since 2008. </span></p> <p><span>Jérôme Jean Haegeli, Swiss Re's Group Chief Economist, said: "Insured losses from severe thunderstorms have been growing due to a mix of factors including inflation, which has contributed to rising construction costs. And, with economic development, overall exposures will continue to increase. That's why investing in protective measures – such as shielding vulnerable communities from floods or improving building codes to protect homes from severe hailstorms – is vital."</span></p> <p><span>Floods also caused above-average losses, driven by events in the UAE, Germany and Brazil, and accounted for 14% of global insured losses. In April, torrential rain caused by severe thunderstorms led to flash floods on the Arabian Peninsula, resulting in unprecedented damage in the UAE. According to industry estimates, insured losses will likely amount to at least USD</span><span> </span><span>2</span><span> </span><span>billion, making it the country's costliest natural disaster on record. While heavy rainfall is expected to increase in a warmer climate, swift urban growth, land use alteration, scarce drainage systems, and dry soils intensify loss severity.</span></p> <p><span style="font-weight: bold;">Total economic and insured losses in H1 2024 and H1 2023</span><br /><span>(USD billion in 2024 prices) </span></p> <table cellpadding="0" cellspacing="0" class="Simple Table" width="100%"> <tbody> <tr> <td style="vertical-align: bottom;"> <p><span> </span></p> </td> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">H1 </span><br /><span style="font-weight: bold;">2024</span></p> </td> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">H1</span></p> <p><span style="font-weight: bold;">2023</span></p> </td> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">H1 previous</span></p> <p><span style="font-weight: bold;">10-y avg</span></p> </td> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">% change </span><br /><span style="font-weight: bold;">vs 10-y avg</span></p> </td> </tr> <tr> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">Economic losses </span></p> </td> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">127</span></p> </td> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">159</span></p> </td> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">98</span></p> </td> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">29%</span></p> </td> </tr> <tr> <td style="vertical-align: bottom;"> <p><span>Natural catastrophes</span></p> </td> <td style="vertical-align: bottom;"> <p><span>120</span></p> </td> <td style="vertical-align: bottom;"> <p><span>152</span></p> </td> <td style="vertical-align: bottom;"> <p><span>91</span></p> </td> <td style="vertical-align: bottom;"> <p><span>31%</span></p> </td> </tr> <tr> <td style="vertical-align: bottom;"> <p><span>Man-made catastrophes</span></p> </td> <td style="vertical-align: bottom;"> <p><span>7</span></p> </td> <td style="vertical-align: bottom;"> <p><span>6</span></p> </td> <td style="vertical-align: bottom;"> <p><span>7</span></p> </td> <td style="vertical-align: bottom;"> <p><span>–</span></p> </td> </tr> <tr> <td style="vertical-align: bottom;"> <p><span> </span></p> </td> <td style="vertical-align: bottom;"> <p><span> </span></p> </td> <td style="vertical-align: bottom;"> <p><span> </span></p> </td> <td style="vertical-align: bottom;"> <p><span> </span></p> </td> <td style="vertical-align: bottom;"> <p><span> </span></p> </td> </tr> <tr> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">Insured losses </span></p> </td> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">66</span></p> </td> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">65</span></p> </td> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">43</span></p> </td> <td style="vertical-align: bottom;"> <p><span style="font-weight: bold;">54%</span></p> </td> </tr> <tr> <td style="vertical-align: bottom;"> <p><span>Natural catastrophes</span></p> </td> <td style="vertical-align: bottom;"> <p><span>60</span></p> </td> <td style="vertical-align: bottom;"> <p><span>60</span></p> </td> <td style="vertical-align: bottom;"> <p><span>37</span></p> </td> <td style="vertical-align: bottom;"> <p><span>62%</span></p> </td> </tr> <tr> <td style="vertical-align: bottom;"> <p><span>Man-made catastrophes</span></p> </td> <td style="vertical-align: bottom;"> <p><span>6</span></p> </td> <td style="vertical-align: bottom;"> <p><span>5</span></p> </td> <td style="vertical-align: bottom;"> <p><span>6</span></p> </td> <td style="vertical-align: bottom;"> <p><span>–</span></p> </td> </tr> <tr> <td style="vertical-align: bottom;"> <p><span> </span></p> </td> <td style="vertical-align: bottom;"> <p><span> </span></p> </td> <td style="vertical-align: bottom;"> <p><span> </span></p> </td> <td style="vertical-align: bottom;"> <p><span> </span></p> </td> <td style="vertical-align: bottom;"> <p><span> </span></p> </td> </tr> </tbody> </table> <p><span>Note: H1 previous 10-year average refers to the average first-half losses between 2014 and 2023.
