Natural catastrophes in 2023 caused global economic losses of US$250 billion, with insurers and reinsurers paying US$95 billion of that amount, according to Munich Re.

Last year’s insured losses of US$95 billion are close to the five-year average of US$105 billion, above the 10-year average of US$90 billion, but lower than the 2022 price tag of $125 billion, said Munich Re in .

The report noted that industrialized countries avoided the mega-disasters that often drive up losses, such as Hurricane Ian in 2022, which caused overall losses of US$100 billion and insured losses of US$60 billion. Instead, the loss statistics in 2023 were driven up by the large number of severe regional thunderstorms in the US and in Europe (also known as severe convective storms), which caused overall economic losses of US$76 billion and insured losses US$58 billion. (Economic losses include insured and uninsured losses).

Breaking the price tag down into regions, Munich Re said assets worth around US$66 billion were destroyed in North America, of which US$50 billion were insured, while in Europe the economic price tag for these extreme storms was US$10 billion, of which US$8 billion was insured, Munich Re said.

Loss statistics from thunderstorms in North America and other regions are trending upwards, Munich Re said, noting that scientific research indicates that climate change is driving severe weather with heavy hailstorms.

North America (which includes Central America and the Caribbean) again recorded the highest losses worldwide, although this year its share of global losses was smaller than usual at 40%, compared with the five-year average of 57%, said Munich Re. Natural disasters in North America destroyed assets worth US$100 billion, of which around US$67 billion was insured. In spite of the large number of severe thunderstorms, the loss amount for all natural disasters was less than that of the previous year (2022) when overall losses came to US$160 billion, with insurance paying for US$100 billion of the total cost.

Costliest Events

The year’s most destructive natural disaster – in terms of overall cost and human life – was the earthquake series in southeast Turkey and Syria in February. With a 7.8 magnitude, it was the strongest quake to hit Turkey in decades. Some 58,000 people were killed, many buildings collapsed, and there was significant damage to infrastructure, said Munich Re.

With overall losses of around US$50 billion, it was also the year’s costliest natural disaster but insured losses came to just US$5.5 billion, despite the fact that earthquake insurance is mandatory for residential buildings in Turkey under the Turkish Catastrophie ÈȵãºÚÁÏ Pool (TCIP).

The second-costliest natural disaster in terms of overall economic losses was Typhoon Doksuri, which brushed the coastline of the Philippines before making landfall at Jinjiang in Fujian province on the Chinese mainland in July. With wind speeds of around 180 kilometers per hour (nearly 112 miles per hour), Doksuri was accompanied by extremely heavy rainfall that triggered destructive flooding. Overall losses came to around US$25 billion, of which only roughly US$2 billion was insured – an example of the large insurance gap for natural disasters that persists in China, Munich Re said.

As the third-costliest event in terms of overall losses, Hurricane Otis was described by Munich Re as another “exceptional event” because it intensified so rapidly. Within 24 four hours, it developed from a weak tropical storm to the highest-category hurricane, making landfall in Acapulco with wind speeds of up to 265 km per hour (165 mph) – the most severe storm on record to hit Mexico’s Pacific coast. Overall losses are estimated at US$12 billion, with insured losses at around US$4 billion due to the high concentration of hotels in the city.

“Doksuri and Otis fall into the pattern that scientists expect as a result of climate change, namely a shift towards an increased number of intense storms and storms with extreme rainfall. Experts also attribute the more frequently observed rapid intensification of tropical storms to climate change,” said Munich Re.

“The warming of the earth that has been accelerating for some years is intensifying the extreme weather in many regions, leading to increasing loss potentials. More water evaporates at higher temperatures, and additional moisture in the atmosphere provides further energy for severe storms. Society and industry need to adapt to the changing risks – otherwise loss burdens will inevitably increase,” according to Ernst Rauch, chief climate scientist, in a statement.

Other findings from the Munich Re report include:

• Overall economic losses from natural disasters were dominated by severe storms: 76% of these losses were weather-related, while 24% had geophysical causes.
• Temperature records were broken in 2023 in the hottest year since measurements began, topping off a decade of the hottest years on record.
• Two thunderstorm outbreaks in the US in March (Midwest) and in June (Texas) were among the year’s costliest natural disasters worldwide in terms of insured losses. These thunderstorm series alone caused combined overall losses of US$17 billion, with insurance according for around US$12 billion of the total.
• Large parts of the coastal town of Lahaina on the island of Maui in Hawaii were destroyed in August by a devastating wildfire, which brought overall losses of an estimated US$5.5 billion, of which roughly US$3.5 billion was insured.
• Losses from natural disasters in Europe came to US$83 billion (largely due to the earthquake in Turkey) with insured losses amounting to around US$19 billion. In addition, storms in the Alpine region and in the Mediterranean area contributed to record thunderstorm losses. In July and August, hailstones measuring up to 19 centimeters (7.48 inches) in diameter caused billions of dollars of losses in northern Italy and several other regions.
• In the Asia-Pacific and Africa region, the overall losses in 2023 of US$64 billion were slightly lower than in the previous year of US$66 billion. Approximately US$8 billion of the overall amount was insured, compared with 2022 when the insured price tag was US$11 billion.
• Japan, a country highly exposed to natural hazards, was largely spared major damage in 2023.
• While Typhoon Doksuri was the year’s costliest disaster in terms of overall losses, two major catastrophes in New Zealand together accounted for the highest insured losses in Asia-Pacific (around US$4 billion). Massive floods in and around Auckland, New Zealand, in early February, caused insured losses of nearly US$2 billion and overall losses of US$2.9 billion. In mid-February, Cyclone Gabrielle hit New Zealand’s North Island and Norfolk Island, resulting in huge damage and bringing losses at similar levels to those from the floods.
• In September, around 3,000 people were killed in a 6.8-magnitude earthquake in Morocco, the strongest quake to hit Morocco in more than 100 years. Overall losses came to approximately US$7 billion with only US$300 million taken up by insurance.
• The number of deaths caused by natural disasters rose to 74,000 in 2023, well above the annual average of the last five years of 10,000 per year. Around 63,000 people across the globe (85% of the year’s total fatalities) lost their lives as a result of earthquakes – more than at any time since 2010.
