The International Association of Insurance Supervisors (IAIS), in collaboration with the World Bank Group, has developed and submitted an input paper to the G20 Sustainable Finance Working Group (SFWG), outlining strategic actions to address the widening protection gap in natural catastrophe (NatCat) insurance coverage across both developed and emerging economies.
According to a statement from the IAIS, the paper identifies the persistent and escalating risks posed by natural catastrophes such as hurricanes, typhoons, wildfires and floods, noting that their frequency and intensity continue to rise globally. This growing trend, the paper warns, is pushing the economic and social costs of such disasters to unsustainable levels, underscoring the urgent need for coordinated international action.
The IAIS and World Bank Group emphasise that natural catastrophe protection gaps are not confined to emerging markets alone, but remain a global challenge that demands global solutions. However, the burden is disproportionately heavier on emerging market and developing economies (EMDEs), where low insurance penetration, affordability constraints, underdeveloped insurance ecosystems, and limited access to risk modelling tools and data exacerbate vulnerabilities. In these regions, the absence of adequate financial safety nets heightens exposure to economic shocks, leaving governments, communities, and individuals without the means to recover swiftly from climate-driven disasters.
Described as a “guide for action,” the paper lays out a suite of practical and implementable measures that governments, insurance supervisors, and industry stakeholders can adopt to narrow protection gaps, particularly in EMDE jurisdictions.
It stresses the need to first build foundational capacities that support the effective deployment of insurance-based solutions. These foundational steps include strengthening local capacity to assess natural catastrophe exposures, developing risk-based and proportionate regulatory frameworks, improving financial literacy and risk awareness at all levels of society, and incentivising risk mitigation through forward-looking policies such as disaster-resilient building codes and resilient public infrastructure.
Beyond these foundational steps, the paper also explores the transformative potential of insurance innovation in enhancing resilience and reducing the financial impact of climate and disaster-related events. It highlights parametric insurance as a promising solution that enables rapid payouts based on pre-agreed triggers, offering efficiency and speed in times of crisis.
It also recommends microinsurance as a critical tool to extend coverage to low-income populations, enabling broader social inclusion in financial protection schemes.
Additionally, the paper points to risk transfer mechanisms—such as catastrophe bonds, reinsurance structures, and regional risk pools—as essential strategies to diversify and distribute risk, thereby improving affordability and financial sustainability.
In its statement, the IAIS further underscores the centrality of collaboration in bridging protection gaps. The paper advocates for the development of public-private insurance programs (PPIPs) that bring together governments, regulatory bodies, insurers, development finance institutions, and civil society. Such collaboration, the IAIS notes, can enable the design of scalable and targeted insurance solutions that respond directly to the needs of vulnerable populations, while also leveraging the technical, financial, and operational capacities of each stakeholder.
The joint effort by the IAIS and World Bank Group aligns with the G20’s wider sustainable finance agenda, aiming to integrate climate risk resilience into financial systems while promoting inclusive economic recovery. With natural catastrophes posing a growing threat to global financial stability and development progress, the input paper is expected to inform policy discourse at the highest levels and catalyse meaningful reforms across jurisdictions.
