European flood economic losses

A July 2026 study by Allianz Research modeled a severe 2027 flood in Greece, estimating a total economic impact of €6.9 billion—about 0.8 % of the country’s GDP—including €1.2 billion in direct damage and broader effects that would cut household disposable income by 5 % and raise inflation by roughly 1 %. The report highlighted that floods are Europe’s most frequent and costly natural hazard, with total losses rising from €63.1 billion in 2000‑2009 to €88.6 billion in 2020‑2025, and projected that under a 3 °C warming scenario annual EU flood losses could reach €50 billion by 2100.

Later that month, an Allianz Trade report showed that cumulative flood‑related losses across Europe have surged by about 40 % since the start of the 21st century, reaching €226 billion in the first quarter of the current century. While the number of flood events remains around 46 per year, greater population and infrastructure concentration in flood‑prone areas amplifies financial impacts, with post‑flood investment dropping 10.5‑14.6 % compared with baseline scenarios. The same release noted rising summer temperatures driving severe drought risk in Norway, threatening agriculture, hydropower, forest fire incidence and food‑energy prices across the continent.
