The Incorporating National Support for Unprecedented Risks and Emergencies Act, or INSURE Act, mandates the Secretary of the Treasury to establish a federal catastrophic property loss reinsurance program within four years. This program aims to provide reinsurance for qualifying primary insurance companies against significant property losses caused by natural disasters, thereby stabilizing insurance markets and encouraging comprehensive coverage for residential and commercial properties. The program will phase in coverage for various catastrophe perils, including wind, hurricane, severe convective storm, wildfire, and flood , with earthquake coverage contingent on a future report. To participate, insurers must offer an all-perils property insurance policy and engage in loss prevention partnerships with policyholders. Participating insurers will pay quarterly premiums into a Federal Catastrophe Reinsurance Fund , which will pay claims when an insurer's losses exceed a set financial threshold, with the Secretary able to issue U.S.-guaranteed notes if the Fund is insufficient. An advisory committee, comprising diverse stakeholders, will guide the Secretary on program design and premiums. The Act also requires the Secretary to establish a statistical plan for collecting quarterly, policy-level claim transaction data from participating insurers, shared with federal and state entities for risk assessment. Additionally, it establishes a pilot program for multi-year all-perils property insurance policies , allowing premium adjustments for construction costs or home value but not for changes in peril risk assessment, and encouraging loss mitigation investments.
