Reciprocal insurance exchanges (RIEs) in the United States have experienced significant growth as new entrants seek to address capacity shortages, particularly in hurricane-prone regions along the southern coasts, according to ALIRT Insurance Research.
In its latest industry report, Overview of Reciprocal Insurance Exchanges and Recent Market Trends, ALIRT revealed that 36 new RIEs—unincorporated entities owned by policyholders, or “subscribers”—have been established between 2017 and 2025, with 18 launched since early 2024. The majority of these new exchanges specialise in providing homeowners coverage in areas vulnerable to hurricanes, including Florida, Texas, and Louisiana.
By the end of 2024, there were 72 companies operating as pure RIEs, writing a total of $51 billion in direct premiums. These RIEs now account for approximately 5% of the total US property and casualty (P&C) premiums market.
“Reciprocal Insurance Exchanges are stepping in once again to fill coverage gaps, particularly in high-risk property markets,” said Ricky Cheney, Senior Analyst at ALIRT and the author of the report. “Their rapid growth highlights both their innovative approach and the financial vulnerabilities tied to insuring catastrophe-exposed regions.”
RIE Model: Innovation and Risk
The structural model of RIEs differs significantly from traditional stock or mutual insurers. Policyholders in RIEs directly share in both profits and losses, appointing an “attorney-in-fact” (AIF) to manage operations. This arrangement allows for greater capital flexibility but can also create misalignment between policyholders’ interests and investors’ priorities.
The financial health of RIEs varies widely. Larger exchanges such as USAA, Farmers, Erie, Auto Club, and CSAA continue to operate with strong capitalisation and conservative financial strategies. However, smaller, newer RIEs face increasing pressure from volatile underwriting results. In fact, eight RIEs reported ALIRT Scores below 30, indicating weak financial performance and raising concerns about their long-term sustainability.
Risks from External Investors and Managing General Agents
The report also highlighted a growing concern regarding the increasing involvement of private investors and managing general agents (MGAs) in new RIEs. These entities are supporting the exchanges through surplus notes, which could introduce “moral hazard” dynamics. This arrangement allows external investors to profit from management fees while being less exposed to the underwriting risks associated with the business.
Legal Reforms Offer Hope for New RIEs
The report noted that legal reforms in key markets like Florida and Louisiana, alongside a stabilising reinsurance market, are expected to provide some relief to newer RIEs. These reforms could help create a more stable operating environment for the growing number of exchanges navigating the challenging property insurance landscape.
