Where does climate risk insurance work, and where does it fall short?
The answer depends heavily on who you are and where you live. For wealthy homeowners in countries with stable insurance markets, climate risk insurance can be a functional tool — but even there, it's under strain. A 2024 study of US property insurance markets found that policy choices made today will profoundly shape future risk levels, disaster recovery, and housing markets over the next 3 to 15 years [1]. The same study warns that without careful regulation, insurance markets can destabilize housing and mortgage markets [1]. In contrast, for the most vulnerable populations — like small farmers in developing countries or indigenous communities — climate risk insurance is often unavailable or poorly designed. Research on Pacific Small Island Developing States (PSIDS) found that effective climate risk insurance products for vulnerable groups are 'almost non-existent' [4]. A case study in La Guajira, Colombia, showed that while a socially inclusive insurance model is possible, it requires tailoring to local needs, such as offering in-kind compensation (not cash) for women entrepreneurs and indigenous communities [2].
Why is insurance pricing a barrier to real-world use?
A major obstacle is that insurance premiums often don't reflect the true risk of climate disasters, which undermines the entire system. A 2022 study of the $15 trillion US homeowners' insurance market found that state-level regulations have caused a 'decoupling' of insurance rates from actual risk [5]. In states with the most restrictive regulations, rates are least reflective of risk, and insurers have been cross-subsidizing these high-friction states by raising rates in low-friction states [5]. This means households in less-regulated states are effectively paying for the risks of households in more-regulated states, which the authors argue 'questions whether insurance rates can play a useful role in steering climate adaptation' [5]. On the other hand, charging risk-based premiums — as many forward-looking models recommend — could incentivize people to adapt (e.g., by building stronger homes), but it also makes insurance unaffordable for many [6]. A 2024 review of insurance modeling found that most forward-looking models show climate change will 'highly exacerbate future risk and increase insurance premiums' [6], creating a tension between affordability and risk signaling.
Do people actually want climate risk insurance, and do they trust it?
Even when insurance is available, demand is often low — and a key reason is that people don't perceive climate change as a personal threat. A 2023 study of US flood insurance found that demand for voluntary coverage is higher in areas where more people are worried about global warming, and that individuals who do not perceive climate change as a risk are more likely to terminate their flood insurance after an unanticipated premium increase [8]. This partisan divide in climate beliefs directly affects insurance uptake [8]. In developing countries, the barriers are even steeper: a 2025 study found that while climate insurance is relatively affordable, demand remains low due to accessibility issues and lack of awareness [3]. Interviews with community and government actors in Colombia revealed deeper concerns: people worry that climate risk insurance could become a 'profit-driven enterprise' and create dependency, leading to maladaptation and moral hazard [7]. There is also fear that using foreign funds for insurance could undermine territorial sovereignty [7]. These findings suggest that for insurance to work, it must be accompanied by education, trust-building, and safeguards against exploitation.

Insurance and climate risks: Policy lessons from three bounding scenarios
Using three bounding scenarios for Florida's insurance market, this 2024 study shows that near-term policy choices (1-3 years) will profoundly shape medium-term (3-15 years) risk levels, disaster recovery, and housing markets, emphasizing the need for careful long-term planning.

Interviews with community and government actors in Colombia revealed that key limitations to disaster risk finance include lack of knowledge, corruption, and concerns that insurance could become profit-driven, create dependency, and undermine territorial sovereignty.
Climate risk perceptions and demand for flood insurance
A 2023 study of US flood insurance found that demand for voluntary coverage is higher in areas with more people worried about global warming, and that individuals who do not perceive climate change as a risk are more likely to drop coverage after premium increases, with partisan polarization driving these beliefs.
