Heatwaves may cut GDP by 0.5 pct points in Europe, Allianz says

Allianz Research forecasts that recent heatwaves could reduce Europe's 2025 GDP by 0.5 percentage points, with Spain potentially seeing a 1.4 percentage point decline. Globally, the firm projects a 0.6 percentage point GDP reduction this year, primarily due to decreased labor productivity caused by extreme temperatures. This underscores the increasing economic costs of climate change and the necessity for adaptive measures to mitigate productivity losses.

Analysis

A recent report from Allianz Research quantifies the significant economic drag from increasing heatwaves, projecting a potential 0.5 percentage point reduction in Europe's GDP for 2025 and a 0.6 percentage point global GDP loss for the current year. The impact is unevenly distributed, with Southern European nations facing the most severe consequences; Spain's GDP is forecast to decline by as much as 1.4 percentage points, while Italy and Greece could see losses of nearly one percentage point. In contrast, Germany's projected impact is a more moderate 0.1 percentage points. The primary driver for this economic headwind is identified as reduced labor productivity, a risk substantiated by an International Labour Organization forecast that heat stress will cut total potential working hours by 2.2% globally by 2030. The severity of this productivity loss is underscored by Allianz's comparison of a day with temperatures over 32°C to the economic impact of half a day of strikes, highlighting a tangible and growing physical risk associated with climate change that necessitates structural adaptation in urban and workplace environments.

Key Decisions for Investors

• Investors should reassess geographic allocations, as the report indicates a significant and varied macroeconomic headwind for European economies, with Southern European countries like Spain and Italy facing substantially greater GDP risk than northern counterparts like Germany.
• Consider screening for companies either vulnerable to or benefiting from this trend; sectors like agriculture, construction, and tourism with high outdoor labor exposure may face margin pressure, while firms specializing in climate adaptation technologies such as cooling systems and energy-efficient infrastructure could see increased demand.
• This analysis provides a quantifiable physical climate risk, reinforcing the need to integrate ESG factors into risk management, specifically by scrutinizing corporate disclosures on labor force resilience and supply chain adaptations in heat-prone regions.
• Treat these projections as a leading indicator for potential downward revisions to earnings and growth forecasts for companies with significant operations or supply chains in the most affected regions, including the U.S., China, and Southern Europe.
