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.
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.
| Risk type | ROI | Investment | Avoided damage | Measure | Climate trend |
|---|---|---|---|---|---|
| Heavy rain / flooding | 6x Payback in <1 event | €2,000 to 6,000 | €660m/year | Backflow protection, drainage | Rising R20 events |
| Heat stress (staff) | 2,5x Payback 2 to 3 summers | €30 to 90/m² | 3 to 12 % productivity loss | Split air-con / shading | 35 to 78 heat days (SSP5-8.5) |
| Flood (site) | 6,3x Payback in <1 event | €200 to 500/linear m | €380,000 Ø | Mobile barrier / stop logs | Rising extreme events |
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.
