Natural Hazards Balance Sheet 2025: Why Prevention Is the Future of Risk Management

The year 2025 left a distinct mark on the insurance industry and sent a clear message: climate change is no longer an abstract future forecast but a balance sheet reality. For Governance, Risk, and Compliance (GRC) professionals, the current figures from the German Insurance Association (GDV) serve as a wake-up call. They illustrate that financial risk transfer alone is reaching its limits. The discussion is now definitively shifting from claims settlement to imperative climate adaptation.

Key Takeaways

• The year 2025 caused insured losses from natural hazards amounting to approximately 8.7 billion euros.
• The main drivers of these damages were severe flooding events and flash floods, particularly in Southern Germany.
• The insurance industry warns that without state and structural prevention, premiums could become unaffordable in the long term.
• The GDV calls for legal building bans in flood zones and a mandatory climate risk assessment for buildings.
• Companies must adapt their risk strategies: Structural resilience is becoming more critical than insurance policies alone.

The 2025 Damage Record: A Turning Point for Risk Management

With a claims volume of nearly nine billion euros, 2025 ranks among the most costly years for the insurance sector. Unlike in previous years, where a single major event often dominated the statistics, 2025 was characterized by an accumulation of extreme weather patterns. The persistent flood situation in Bavaria and Baden-Württemberg demonstrated that existing infrastructure is no longer adequate to cope with such water masses.

For risk managers, this development means that historical loss data has served its purpose as the sole basis for forecasting. The volatility and intensity of events are increasing. Those who build risk models exclusively on past values run the risk of massively underestimating the company’s actual exposure. The 2025 balance sheet is empirical proof that extreme weather events are part of the new normal.

Limits of Insurability and the Call for Adaptation

Jörg Asmussen, Chief Executive Officer of the GDV, makes it clear in his analysis that insurance coverage alone cannot be the answer to climate change. If damages occur at this frequency, insurance coverage without accompanying measures will become either unaffordable or economically inefficient.

The narrative is changing fundamentally. It is no longer primarily about who pays for the damage, but how the damage can be prevented. For companies, this means that the “license to operate” at locations with high physical climate risks is endangered if massive investments are not made in local adaptation measures. Pure risk transfer to an insurer will increasingly be tied to strict conditions or simply become too expensive.

Regulatory Demands: Building Law in Focus

A central demand resulting from the 2025 balance sheet concerns building regulations. The GDV advocates that construction should effectively be prohibited in designated flood zones. Furthermore, building permits should be mandatorily linked to a climatic hazard assessment.

This has far-reaching consequences for the compliance and legal departments of companies. When expanding, building new production sites, or planning logistics centers, planning must go far beyond current statutory minimum standards. Those who still build according to old standards in risk zones today are knowingly creating “stranded assets” that may be neither insurable nor salable in a few years.

Prevention as a Corporate Duty

The call for more prevention is directed not only at the state but also at the private sector. Climate adaptation means concrete structural and organizational measures: unsealing corporate surfaces, installing flood barriers, backflow protection, and heat-resistant facades.

From a GRC perspective, this topic must be moved out of the facility management silo and anchored at the board and supervisory board levels. The physical resilience of assets is directly linked to business continuity. Production downtime caused by flooding often weighs heavier than the pure property damage, and restoring complex supply chains takes longer than the transfer of the insurance sum.

Controversy Surrounding Compulsory Insurance

The political discussion regarding compulsory natural hazard insurance remains virulent in 2025. The insurance industry continues to reject such a mandate without accompanying prevention measures. The argument is economically valid: compulsory insurance does not reduce a single risk; it only redistributes the costs. Without adapting building regulations, such insurance would merely lead to continued construction in danger zones—at the expense of the collective.

For companies, this debate is relevant because legal interventions in the insurance market will influence premium pricing and the availability of coverage capacities. GRC experts should develop scenarios on how a potential compulsory insurance scheme or alternative models would impact operating costs.

FAQ

Why was the 2025 claims year so expensive?

The high costs resulted from a combination of widespread flooding in Southern Germany and an increase in local flash floods, which affected areas with a high density of insured assets.

What is meant by “climate adaptation” in a GRC context?

It refers to strategic and operational measures to make companies more resilient to climate risks. This includes structural protection, redundant supply chains, and adapted emergency plans.

Why is insurance no longer sufficient?

Insurance covers financial losses but does not prevent business interruptions or reputational damage. Additionally, premiums will rise to uneconomic levels without prevention.

What changes in building law are being demanded?

Experts are calling for a ban on construction in flood zones, a mandate for climate-adapted construction methods, and the integration of natural hazard analyses into the building permit process.

How should companies react now?

Companies should conduct a detailed risk analysis of their locations regarding physical climate risks and allocate a budget for preventive structural protection measures.
