How Much Are Property Insurance Premiums Affected by Climate Change?

Climate change is now an immediate issue; its impacts are experienced globally, affecting everything from climate trends to financial security. More intense and frequent natural disasters are demolishing homes and businesses at unprecedented levels, while complete food systems are endangered due to droughts, floods, and other climate-related interruptions. These increasing effects are transforming the property insurance environment, putting property owners and insurers in a vulnerable situation.

American property owners already dealing with severe weather now confront a new and urgent issue: vanishing property insurance. Private insurance firms are progressively retreating from providing coverage in specific high-risk regions, determining that the dangers and probable losses from climate change surpass any expected gains. This problem has mainly impacted coastal U.S. states like Florida and California. California, where destructive wildfires and flooding have rendered property insurance a challenging endeavor while Florida faces a never-ending parade of hurricanes causing both wind and flood damage. In these locales insurance companies have reacted not only by increasing premiums but also withdrawing from insuring any property in entire states.

The insurance sector, especially property insurance—is one of the industry’s most significantly affected by climate change. As extreme weather incidents become more common and intense, they are causing significant changes in premium costs. Although climate change is certainly exacerbating these disasters, additional factors are intensifying the issue. Even with increasing climate-related dangers, developers persist in leading Americans to areas vulnerable to disasters. More expensive homes and businesses are being constructed in regions that are becoming more susceptible to hurricanes, wildfires, and flooding, intensifying the risk of potential losses. These trends pose a significant question: to what extent are property insurance premiums influenced, and what implications does this have for homes and businesses?

The Growing Impact of Climate Change on Property Risks

Climate change intensifies natural disasters such as hurricanes, wildfires, floods, and droughts. The rising frequency and intensity of natural disasters are damaging more assets every year. The number of US catastrophic events increased by 32% between 2019 and 2022. Insured losses escalated from US $25 billion in 2019 to US $99 billion in 2022, accounting for 80% of global natural catastrophe losses. As the severity and frequency of losses caused by natural catastrophes continue to accelerate at an estimated average annual growth rate of 5% to 7%, US homeowners could face up to US$118 billion in losses by 2030 due to weather events. These events are not only more frequent but also more severe, resulting in greater property damage and higher insurance claims. For example:

• Hurricanes: Rising sea levels and warmer ocean temperatures fuel stronger storms. Damages from hurricanes like Ian (2022) and Ida (2021) resulted in billions of dollars in insured losses. Hurricane Harvey caused $125 billion in property damage in 2017.
• Wildfires: Prolonged droughts and higher temperatures create ideal conditions for wildfires. In California, wildfire-related insurance claims exceeded $13 billion in 2018 alone. The 2019–20 Australian bushfires killed more than a billion animals and caused more than $4.4 billion in damage. Projections for the January 2025 southern California fires are $250 billion in losses, including 12,300 homes, businesses, churches and schools.
• Flooding: Increased rainfall and urbanization have made flooding a more pressing issue. FEMA reports that floods are the most common and costly natural disaster in the U.S., with damages surpassing $20 billion annually in recent years.

The Increasing Influence of Climate Change on Property Risks

Climate change exacerbates natural disasters like hurricanes, wildfires, floods, and droughts, elevating their occurrence and intensity. This growing trend has led to increasing damage to assets annually. From 2019 to 2022, the occurrence of catastrophic events in the U.S. increased by 32%. Insured losses surged from $25 billion in 2019 to $99 billion in 2022, accounting for 80% of worldwide natural disaster losses. As the intensity and occurrence of natural disasters rise by an estimated 5% to 7% each year, U.S. homes might incur losses reaching $118 billion by 2030 due to weather-related incidents. These increasing losses are not just leading to more insurance claims but are also transforming the property insurance environment. Examples include:

• Hurricane: Increasing sea levels and hotter ocean temperatures are driving more powerful and damaging storms. Hurricanes such as Ian (2022) and Ida (2021) caused billions of dollars in insured damage. Hurricane Harvey in 2017 resulted in a remarkable $125 billion in economic losses, underscoring the increasing dangers linked to such storms.
• Wildfires: Extended periods of drought and increasing temperatures foster perfect circumstances for wildfires. In California, wildfire-related insurance claims surpassed $13 billion in 2018. The catastrophic Australian bushfires of 2019–20, which resulted in the death of over a billion animals, inflicted over $4.4 billion in damage, highlighting the worldwide threat of wildfires. 2025 California fire loss projection $250 billion.
• Flooding: The rise in rainfall intensity, along with urban development, has turned flooding into one of the most urgent problems associated with climate change. FEMA states that floods rank as the most prevalent and expensive natural disaster in the U.S., with damages surpassing $20 billion each year in recent times.

How Climate Hazards Lead to Increased Premiums

Insurance premiums are determined by assessing risk, and climate change has significantly changed how insurers manage this process. Due to the rising occurrence and intensity of climate-related incidents, insurers have had to reevaluate their risk models. Increasing losses from weather events, along with inflation-related expenses for repairing damaged properties, have significantly affected the profitability of property insurers. This pressure is especially intense in a sector that is already facing challenges from consistently elevated loss ratios. In 2022, the U.S. homeowner market was linked to 75% of the property and casualty sector's insured losses, totaling $74 billion. These alterations have been evident in various significant manners:

• Increased Premiums in High-Risk Locations: Properties situated in disaster-sensitive zones, like coastal regions at risk of hurricanes, areas prone to wildfires, or flood zones, have seen the largest hikes in premiums. For instance, Florida—a state often affected by hurricanes—has experienced a rise in home insurance premiums exceeding 50% over the last five years. Across the country, home insurance premiums increased by an average of 11% last year, with high-risk areas such as Florida facing spikes of up to 35%. These rapid rises have turned affordability into a major issue for numerous homeowners.
• Higher Reinsurance Expenses: Insurers frequently rely on reinsurance (insurance for insurers) to safeguard against significant losses. Nonetheless, climate change has led to an increase in claims, causing reinsurers to raise their rates. These increased expenses are transferred to policyholders, resulting in higher premiums. Reinsurance rates are anticipated to stay elevated because reinsurers have inadequate retained earnings. This deficit not only restricts their capability to meet capital costs but also obstructs their potential to establish more robust balance sheets needed for a landscape that is increasingly prone to risk.
• Tighter Underwriting Standards: Insurance providers are increasingly choosing to be more discerning in providing coverage for high-risk regions. In certain situations, coverage is being refused completely, compelling homeowners to seek state-operated insurance programs, which are typically costlier and assessable. For instance, from 2020 to 2022, CA insurers refused to renew 2.8 million homeowner policies in the state, based on the latest information from the California Department of Insurance. This includes 531,000 in Los Angeles County, where fires are currently blazing.

Regional Variations in Premium Hikes

Although climate change influences areas worldwide, its effect on insurance premiums differs greatly by region. Insurance companies employ regional risk evaluations to modify premiums according to the unique climate-related issues encountered by various regions. Major trends consist of:

• Coastal Regions: Coastal areas are especially susceptible to hurricanes, storm surges, and increasing sea levels. These risks have resulted in significant premium hikes, with certain homeowners experiencing annual expenses that have doubled or tripled in the last ten years. States such as Florida, Louisiana, and Texas have experienced some of the largest increases because of their vulnerability to severe storm events
• Western U.S.: The western region of the United States is encountering increasing wildfire threats as a result of extended droughts and elevated temperatures. These factors have resulted in property insurance being both pricier and more difficult to acquire. In places such as California, certain insurers have chosen to completely exit the market, compelling homeowners to seek state-provided insurance solutions.
• Midwestern States: The Midwest's susceptibility to tornadoes, heavy storms, and flooding has resulted in continuous increases in premiums. Rising rainfall and the increasing occurrence of severe weather events have compelled insurers to modify their risk models, affecting homeowners in states like Missouri, Kansas, and Oklahoma.

Wider Economic Consequences

Increasing property insurance costs go beyond just the financial strain on single policyholders, generating wider economic repercussions. These consist of:

Housing Affordability: Elevated premiums greatly raise the total expense of homeownership, especially in high-risk locations. This extra cost may discourage prospective buyers, making it more challenging for families to purchase homes in areas susceptible to natural disasters. For current homeowners, escalating insurance expenses can pressure household finances, particularly for those already dealing with financial stress.

Real Estate Arena: The increasing financial dangers linked to climate change are affecting purchaser actions. Prospective homeowners and investors might steer clear of high-risk zones, resulting in lowered demand and diminishing property values in at-risk areas. On the other hand, more secure areas could see a rise in demand, which might lead to higher prices and affordability issues in those markets.

Business Operations: For businesses, increasing insurance premiums lead to elevated operating expenses. Companies located in high-risk regions encounter higher costs to insure their assets, potentially diminishing profitability and limiting growth strategies. This could also affect supply chains and job prospects in areas significantly impacted by climate-related hazards.

Adjustment and Alleviation: What Steps Can Be Taken?

To address the increasing financial burden of insurance premiums affected by climate, multiple stakeholders are adopting strategies focused on minimizing risks and enhancing resilience. Main strategies encompass:

• Resilience Investments: Enhancing properties to endure severe weather occurrences is an effective method to reduce risks and subsequently, insurance costs. Steps like adding hurricane-proof windows, using fire-resistant construction materials, or raising foundations in flood-prone zones can enhance property insurability and reduce vulnerability to damage. These forward-thinking investments assist individual property owners while simultaneously alleviating the overall burden on insurers.
• Government Initiatives: Publicly financed insurance schemes, like the National Flood Insurance Program (NFIP) in the U.S., offer vital protection in areas with high risk. Nonetheless, numerous programs encounter difficulties concerning sustainability and financial stability. Continuous reforms are essential to guarantee they stay sustainable while properly tackling the rising threats presented by climate change.
• Private Sector Innovation: Insurers are progressively encouraging property owners to implement sustainable and resilient practices. For instance, rebates or incentives could be provided for the installation of solar panels, utilizing eco-friendly building materials, or adopting water conservation systems. These efforts promote eco-friendly behaviors while minimizing vulnerability to climate-related threats.
• Climate Action: Tackling the fundamental causes of climate change is crucial for sustainable risk mitigation. Strategies focused on lowering greenhouse gas emissions, shifting to renewable energy sources, and encouraging sustainable land management are essential elements of an all-encompassing approach to lessen climate effects. Joint initiatives among governments, businesses, and communities are essential for attaining significant advancement.

Conclusion

Climate change is fundamentally reshaping the property insurance market, increasing premiums as the dangers linked to severe weather events grow. Homeowners and businesses located in high-risk zones encounter considerable financial difficulties, highlighting the pressing requirement for both personal and collective measures. The wider economic effects—from the affordability of housing to stability in the market—underscore the interrelated aspects of these alterations.

As insurance companies keep adjusting their models to cope with changing climate conditions, policyholders need to take initiative in reducing risks. This encompasses funding resilience initiatives, promoting sustainable construction methods, and endorsing policies designed to lower greenhouse gas emissions. By promoting cooperation between governments, insurers, and communities, we can create a more sustainable and climate-resilient future while reducing the financial strain on property owners. Tackling climate change is not merely a challenge for the insurance sector but a worldwide obligation that demands creative and collaborative approaches.
