Extreme weather events show varied short-term economic impact in euro area
An ECB working paper examines the short-term macroeconomic and sectoral effects of extreme weather events in Germany, France, Italy, and Spain. The analysis documents sizable and heterogeneous impacts on real GDP, HICP, and sectoral activity over a one-year horizon.
Mapping climate shocks to economic activity
The paper constructs novel indicators for extreme temperature and precipitation, using percentile thresholds of historical distributions from 1940-2023.
These are integrated into country-specific structural Bayesian VAR models to estimate impacts on real GDP, HICP, and sectoral activity over a one-year horizon.
Germany shows the strongest vulnerability to heatwaves, affecting industrial and energy sectors.
Spain is most exposed to floods and droughts, impacting construction and mining.
Pharmaceuticals are particularly vulnerable to extreme heat, possibly due to reliance on temperature-sensitive transport and water-dependent logistics.
Italy and France show more resilience, with Italy even experiencing temporary activity increases from reconstruction efforts after heavy rainfall.
Defining rare and severe weather conditions
The study defines extreme events using long historical climate records to capture genuinely rare and severe weather conditions, distinguishing them from normal seasonal variations.
It focuses on heatwaves, coldwaves, floods, and droughts across Germany, France, Italy, and Spain.
The analysis combines these climate indicators with monthly economic data, examining responses over the year following an event.
Understanding these short-run fluctuations is crucial for economic forecasting, risk assessment, and policy design, highlighting climate-related risks as a material source of short-term economic risk.
Timely insights, but limited scope
This paper provides timely and granular insights into the short-term economic vulnerabilities of key euro area economies to extreme weather.
While the methodology is robust, the focus on short-term impacts and specific countries means broader, long-term climate adaptation strategies are not addressed.
Policymakers should integrate these findings into immediate risk assessments, but recognize the need for complementary research on systemic climate resilience.
