Climate risk: physical hazards & financial portfolios

The ECB analyses how strongly bank loans and financial assets are threatened by physical climate risks. Here you find current data on exposure and expected losses in the euro area.

The ECB assesses what share of bank loans has been extended to companies in climate-exposed areas. "Gross loss" = estimated damage without insurance. "Net loss" = after deducting collateral. Data as of December 2024.

What do NEAR and CEAR mean?

NEAR - gross loss

The expected annual damage without accounting for insurance or collateral. Shows the full damage potential of a natural hazard.

CEAR - net loss

The expected loss after deducting collateral, insurance and flood protection. Usually 60 to 70 % below the gross loss.

iThe difference between NEAR and CEAR shows how strongly existing protections reduce the actual loss for banks.

Climate-risk prevention - ROI 2.5 to 6.3x

Prevention is among the most economic investments there are. Guide values for typical German commercial sites.

ROIØ 5x return - prevention is cheaper than damage remediation. Insurers and banks increasingly factor climate resilience into premiums and conditions.

ECB stress tests account for climate risks

Banks increasingly price climate risk - know your exposure and hedge it, and you negotiate from the stronger position.

  • Extreme weather cost Europe over €200bn between 2021 and 2024; four years after a drought, output still runs around 3 % lower.
  • In the ECB stress test, fluvial flooding is Germany's single largest hazard: over €3bn expected gross loss per year, around €1.1bn net.
  • 75 % of corporate loans depend on ecosystem services - low-emission firms with a transition plan get better credit terms.
