Climate Insurance Market (2026-2036)

Key Highlights – Climate Insurance Market

• The global climate insurance market is expected to reach USD 420 billion by 2036, at a CAGR of 9.2% from 2026 to 2036, driven by rising climate-related losses, the closing of the protection gap, and the rapid growth of parametric risk transfer.
• Climate losses are large and rising, with insured natural-catastrophe losses of about USD 107 billion in 2025 and economic losses of about USD 220 billion, of which about 49% were insured, the highest insured share on Swiss Re Institute records.
• Secondary perils now dominate losses, as secondary perils, principally wildfires, severe convective storms, and floods, accounted for a record 92% of global insured natural-catastrophe losses in 2025, reshaping how insurers assess and price risk.
• Loss trends are structural, not cyclical, with long-term insured natural-catastrophe losses rising at an estimated 5% to 7% per year, and wildfire insured losses growing at an estimated 12% per year, sustaining structural demand for coverage.
• A large protection gap persists, as the protection gap remains wide, with more than 40% of global economic losses insured over the past decade but 80% to 90% still uninsured in many emerging economies, representing the market's central opportunity.
• Parametric insurance is the fastest-growing structure, with parametric and weather-index insurance, which pays out rapidly on a measured trigger, growing far faster than traditional cover and extending climate risk transfer to agriculture, governments, and underserved segments.
• Reinsurance capacity underpins the market, as reinsurers including Munich Re, Swiss Re, Hannover Re, and SCOR provide the capacity that underpins the market, supported by catastrophe bonds and insurance-linked securities that bring capital-market capacity to climate risk.
• The market is led by global carriers, led by global insurers and reinsurers including AXA, Allianz, Zurich, Chubb, and the Japanese majors, alongside parametric specialists and brokers Aon, Marsh McLennan, Gallagher, and WTW.

Global Climate Insurance Market: Rising Losses, the Protection Gap, and Parametric Risk Transfer Drive Market Growth

The climate insurance market comprises the products and services through which insurers and reinsurers transfer and price climate- and weather-related risks, spanning natural-catastrophe property coverage, agricultural and crop climate insurance, parametric and weather-index solutions, and the reinsurance and capital-market capacity that support them. As the frequency and severity of climate-related events rise, demand for coverage increases, while insurers reassess insurability, pricing, and capacity. This report examines the market's size, drivers and restraints, product and structure mix, perils, end users, the reinsurance and risk-transfer ecosystem, and regional dynamics through 2036.

Rising Climate Losses Drive Demand and Reshape the Market

The central dynamic of the market is the sustained rise in climate-related losses. According to the Swiss Re Institute, insured natural-catastrophe losses reached about USD 107 billion in 2025, and long-term insured losses are rising at an estimated 5% to 7% per year, a structural trend driven by a combination of climate change, economic growth, and the concentration of assets in exposed areas. The 2025 total was reached despite the absence of a major United States hurricane landfall, indicating the growing contribution of other perils. Rising losses increase the demand for coverage and the premiums required to provide it, expanding the market in value terms, while also pressuring insurers to reassess which risks are insurable and at what price. The structural, rather than cyclical, nature of the loss trend is what underpins the long-term growth of the market.

The Protection Gap Is the Market's Central Opportunity and Challenge

The protection gap, the difference between economic and insured losses, defines both the opportunity and the challenge of the market. The Swiss Re Institute reports that about 49% of the roughly USD 220 billion in economic losses in 2025 were insured, the highest insured share on its records, up from much lower levels historically, yet this still leaves about half of losses uninsured. In many emerging economies, 80% to 90% of catastrophe losses remain uninsured. Closing this gap represents the market's largest growth opportunity, requiring affordable products, new structures such as parametric insurance, public-private risk pools, and the integration of insurance with risk adaptation. The scale of the gap, and the social and economic cost of underinsurance, make its closure a priority for insurers, governments, and development institutions alike.

Secondary Perils Redefine Climate Risk

A defining shift in the market is the growing dominance of secondary perils. The Swiss Re Institute reports that secondary perils, principally wildfires, severe convective storms, and floods, accounted for a record 92% of global insured natural-catastrophe losses in 2025, compared with primary perils such as major hurricanes and earthquakes. Wildfire is the fastest-growing risk, with insured losses increasing at an estimated 12% per year. This shift reshapes how insurers model, price, and underwrite climate risk, because secondary perils are more frequent, more geographically dispersed, and historically less well modeled than primary perils. The reassessment of secondary-peril risk is driving changes in pricing, deductibles, coverage terms, and, in some high-risk areas, the availability of cover.

Parametric and Index Insurance Accelerate Climate Risk Transfer

Parametric and weather-index insurance is the fastest-growing structure in the market. Rather than indemnifying assessed losses, parametric products pay out automatically when a measured trigger is breached, such as a wind speed, rainfall level, earthquake magnitude, or temperature threshold, enabling rapid payouts without lengthy claims assessment. This structure is well suited to climate risks, to agriculture, to governments and public-sector risk pools, and to underserved segments where traditional insurance is impractical. Parametric agricultural insurance has been growing substantially faster than traditional agricultural cover. The growth of parametric insurance is supported by improvements in satellite data, remote sensing, weather modeling, and specialist underwriters, and it is central to extending climate coverage to the protection gap, though basis risk, the mismatch between payout and actual loss, remains a key challenge.

Agricultural and Crop Climate Insurance Expands

Agriculture is one of the most climate-exposed sectors and a large component of the climate insurance market. Crop and agricultural insurance, much of it covering drought, flood, excess rainfall, and temperature risk, protects farmers and food systems against climate variability, and is frequently supported by government premium subsidies in major agricultural economies including the United States, China, India, and Brazil. Parametric and index-based agricultural insurance, which uses weather and satellite data to trigger payouts, is extending coverage to smallholder farmers in developing economies where traditional crop insurance is impractical. The rising climate risk to agriculture, combined with public support and new parametric structures, makes agricultural climate insurance a significant and growing segment, central to food security and rural resilience.

Reinsurance Capacity, Pricing, and Capital-Market Risk Transfer

Reinsurance capacity underpins the climate insurance market, because primary insurers transfer much of their catastrophe risk to reinsurers. The leading global reinsurers, including Munich Re, Swiss Re, Hannover Re, and SCOR, provide the capacity and modeling that enable primary insurers to write climate risk, and reinsurance pricing and availability strongly influence primary-market terms. Rising losses drove significant reinsurance price increases in recent years, improving capacity and discipline. Catastrophe bonds and other insurance-linked securities bring capital-market capacity to climate risk, transferring peak perils to investors and expanding the total capacity available. The interplay of reinsurance capacity, pricing discipline, and capital-market risk transfer is a key determinant of how much climate risk the market can absorb and at what cost.

Insurability, Market Retreat, and Public-Private Risk Pools

As climate losses rise, the insurability of some risks is increasingly in question. In high-risk areas, including parts of the United States exposed to wildfire and flood and other regions facing repeated extreme events, some insurers have raised prices sharply, restricted coverage, or withdrawn, raising concerns about affordability and availability. This dynamic, sometimes described as a retreat from the riskiest markets, has prompted responses including state-backed insurers of last resort, public-private risk pools, and regulatory intervention. Public and development-sector risk pools, such as regional catastrophe facilities, extend coverage to governments and vulnerable populations. The tension between risk-based pricing, which can make cover unaffordable, and the social need for coverage is a defining challenge, and the design of public-private mechanisms to maintain insurability is central to the market's future.

Market by Geography

North America Climate Insurance Market

North America is the largest climate insurance market, led by the United States, which experiences the highest insured catastrophe losses globally from hurricanes, severe convective storms, wildfires, and floods, and has the deepest insurance and reinsurance markets. The United States is also the focus of insurability concerns, with insurers repricing or withdrawing from high-risk wildfire and flood markets and state-backed insurers of last resort expanding. Canada faces rising wildfire and flood losses. The region's large exposure, deep markets, and prominent insurability challenges make North America the center of the global climate insurance market and the leading source of both premiums and losses.

Europe Climate Insurance Market

Europe is a large and mature market facing rising losses from floods, severe convective storms, wildfires, and extreme heat, with major flood events in recent years driving demand and repricing. The region hosts several of the world's largest insurers and reinsurers, including in Germany, France, Switzerland, Italy, and the United Kingdom, and has active public-private flood insurance schemes. The European Union's focus on climate adaptation and the protection gap supports policy attention to insurance. Europe's deep insurance industry, rising climate losses, and policy focus on adaptation and the protection gap make it a central and growing market.

Asia-Pacific Climate Insurance Market

Asia-Pacific is a large and fast-growing market with high exposure to typhoons, floods, and droughts, and a wide protection gap, as a large share of losses in the region remain uninsured. China and India have large, government-supported agricultural insurance programs and growing catastrophe coverage, Japan and Australia have mature markets exposed to typhoons, floods, and wildfires, and Southeast Asian markets are developing parametric and index solutions to extend coverage. The combination of high and rising climate exposure, large agricultural sectors, and a wide protection gap makes Asia-Pacific a major growth market, particularly for parametric and agricultural climate insurance.

Latin America and Middle East & Africa Climate Insurance Market

Latin America faces significant exposure to floods, droughts, and hurricanes, with large agricultural economies in Brazil, Argentina, and Mexico and a wide protection gap, supporting growth in agricultural and parametric climate insurance, including regional risk facilities. The Middle East and Africa face rising exposure to drought, flood, and extreme heat, with very high uninsured shares and growing use of parametric and sovereign risk-pool solutions, such as regional catastrophe risk facilities, to extend coverage to governments and vulnerable populations. These regions have the widest protection gaps and are important growth markets for parametric, agricultural, and sovereign climate risk transfer.

Competitive Landscape

The global climate insurance market comprises global reinsurers, primary insurers, specialist parametric underwriters and managing general agents, insurance brokers, and public and development-sector risk pools. Global reinsurers provide the capacity and catastrophe modeling that underpin the market, primary insurers write coverage for corporates, farmers, governments, and individuals, specialist parametric underwriters design and distribute index-based products, and brokers structure and place risk. Competition centers on underwriting expertise, catastrophe modeling and data, capacity, pricing discipline, and increasingly on the ability to design parametric and climate-specific products and to close the protection gap profitably.

A central competitive dynamic is the reassessment of climate risk amid rising and shifting losses, which is driving changes in pricing, capacity allocation, and the willingness to write risk in high-exposure areas. Reinsurers and insurers are investing in catastrophe modeling, climate analytics, satellite and sensor data, and parametric product design to price and transfer climate risk more effectively. Specialist parametric underwriters and technology-enabled managing general agents compete by applying advanced data and index design, often in partnership with reinsurers that provide capacity, while brokers compete on placement, structuring, and analytics. The ability to combine capacity, data, and product innovation to profitably extend coverage into the protection gap is the key basis of competition.
