European proposal seeks stronger cover for catastrophe losses
Europe’s financial exposure to natural catastrophes is rising, while a large share of losses still falls outside insurance. A new staff discussion paper from the European Insurance and Occupational Pensions Authority (EIOPA) and the European Stability Mechanism (ESM) sets out a possible European mechanism to manage that gap more effectively. It combines a shared insurance pool with a loan-based backstop for very severe events, with the aim of improving resilience when floods, storms, wildfires or earthquakes cause large losses across the continent.
What is being proposed?
The paper explores a European risk-sharing mechanism for natural catastrophe losses. Under this approach, insurers, reinsurers or national schemes would join a pool that is funded in advance through risk-based premiums. That pool would cover part of the losses once they pass a defined threshold. For the most extreme tail events, a loan-based backstop would provide additional funding. The authors present this as a technical contribution to policy debate, rather than a final policy proposal, and stress that any European solution would need to work alongside existing national arrangements and broader adaptation efforts.
Why pool risks at European level?
The main argument is that risks differ strongly across countries and hazards, which creates room for diversification. Earthquakes weigh more heavily in some parts of Europe, while floods, storms, hail or drought-related losses dominate elsewhere. By combining those risks, insurers may need less capital than under separate national solutions. The paper’s modelling suggests that pooling across countries and perils could reduce overall capital needed to support these risks by up to 67%. That could help expand insurance capacity, reduce volatility and make cover for natural catastrophes more affordable and predictable over time.
How would the backstop work?
The proposed backstop would act as a lender of last resort when losses exceed the pool’s available funds. Rather than relying on ad hoc support after a disaster, the mechanism would provide pre-defined financing terms for extreme scenarios. According to the paper, this could lower funding costs, smooth cash flows and reduce pressure in stressed reinsurance markets. The analysis suggests the required lending capacity could range from €10 billion to €65 billion, depending on how much tail risk the backstop is designed to absorb and how losses evolve over time.
The wider message is that physical climate risk is no longer only a question of local damage. Large catastrophe losses can affect insurance availability, capital requirements, asset values and financial stability across borders.
