Insurers Face the Music: Navigating a Risky Future

Insurers are grappling with a challenging and risky future, as climate change escalates the frequency and severity of extreme weather events. The insurance industry is under increasing pressure from regulators and stakeholders to address these risks and adapt their underwriting and pricing practices accordingly. This article explores the strategies insurers are implementing to confront these challenges and the role regulatory changes play in driving their response.

Insurers are taking several steps to address the increasing frequency and severity of extreme weather events. They are investing in new datasets, expertise, and approaches to operationalize climate risk insights (Moody's, 2025). Insurers are also developing consistent scenario-building across both sides of the balance sheet under different Representative Concentration Pathways (RCPs) for physical risk and Network for the Greening of the Financial System (NGFS) scenarios for transition risks (Moody's, 2025). Additionally, insurers are aligning investment and underwriting portfolio strategies with revised risk appetites and transition targets, and calculating capital resource allocation based on strategic resource allocation using revised capital market assumptions, asset and liability management (ALM), and risk capital requirements (Moody's, 2025).

However, insurers face several challenges in this process, including data availability and quality, modeling and analytics, regulatory uncertainty, and capacity constraints (Deloitte, 2019). These challenges highlight the need for insurers to collaborate with regulators, industry peers, and other stakeholders to develop and implement effective strategies for managing climate change risks.

Regulatory changes play a significant role in driving insurers to address climate change risks. As climate change becomes an increasingly pressing issue, regulators are imposing stricter requirements on insurers to ensure they are adequately prepared to manage these risks. In the US, a federal regulator suggested that the potential damage from climate change could be as severe as the fallout from the 2008 financial crisis (Source: "Climate change = insurance risk"). The Insurance Regulator State of Climate Risks Survey conducted by Deloitte found that a majority of US state insurance regulators expect all types of insurance companies' climate change risks to increase over the medium to long term (Source: "Climate risk: Regulators sharpen their focus"). More than half of the regulators surveyed indicated that climate change was likely to have a high impact or an extremely high impact on coverage availability and underwriting assumptions (Source: "Climate risk: Regulators sharpen their focus").

In response to these regulatory changes and concerns, insurers are taking several actions to address climate change risks. They are fortifying their assessment of climate-related risks and taking long-term actions to alleviate and mitigate such exposures. Insurers are using a holistic approach toward managing climate-related risks and developing innovative insurance products that incentivize climate-related risk prevention. They are also implementing adaptation measures to reduce policyholder's physical risk exposures and insured losses and engaging in public-private partnerships to improve the collection and sharing of climate-related loss data and raising awareness about climate change (Source: "Climate change = insurance risk", "Insurance industry response to climate change", and "Climate change is a growing risk for the insurance industry").

In conclusion, insurers are confronting a tricky and risky future as climate change escalates the frequency and severity of extreme weather events. They are implementing various strategies to address these challenges, but they face several obstacles along the way. Regulatory changes play a crucial role in driving insurers to address climate change risks, and insurers are responding by taking proactive measures to mitigate these risks and adapt their underwriting and pricing practices. As the climate continues to change, insurers must remain vigilant and adaptable to ensure the long-term availability and affordability of insurance products.
