Significant legislative amendments in Texas are poised to alter the financial landscape for the Texas Windstorm Insurance Association (TWIA). A recent bill has adjusted the minimum loss funding requirement, effectively halving it from a 1-in-100 year probable maximum loss (PML) to a 1-in-50 year PML. This shift is anticipated to lead to a decrease in the association's need for external risk transfer mechanisms, such as reinsurance and catastrophe bonds, starting in 2026.
This strategic move, spearheaded by Texas lawmakers, aims to alleviate the financial burden on TWIA, ultimately benefiting policyholders. House Bill 3689 explicitly mandates that the association maintain total available loss funding equivalent to at least the 1-in-50 year probable maximum loss. This funding level can be achieved through various means, including reinsurance, alternative financing mechanisms, or a combination thereof, working in conjunction with existing trust funds, public securities, financial instruments, and authorized assessments. Previously, the same statute stipulated a more stringent 1-in-100 year funding level, which had been the basis for TWIA’s financial planning and risk transfer procurement in recent years.
Historically, TWIA has operated with varying funding levels. As far back as 2013, the association’s risk transfer and reinsurance purchases aligned with a 1-in-50 year loss exposure. While the ultimate goal was to reach the 1-in-100 year level, financial resources at the time necessitated a more conservative approach. By 2014, with the introduction of catastrophe bonds into its risk transfer strategy, TWIA was able to incrementally increase its funding to a 1-in-60 year level. It is crucial to note that the association's exposure base has expanded substantially since those earlier periods, making direct comparisons challenging.
For the current hurricane season in 2025, TWIA’s Board had established its 1-in-100 year probable maximum loss (PML) at a substantial $6.227 billion. To address this exposure, the association diversified its funding sources, allocating $2 billion from other financing avenues and $4.227 billion for risk transfer and reinsurance. A significant portion of this risk transfer, specifically $2.45 billion, was secured through catastrophe bonds, with the remaining balance obtained from traditional or collateralized reinsurance markets. The reduction to a 1-in-50 year PML, as now legislated, implies a 98% probability that TWIA’s funding will be adequate at this revised level. Internal discussions among TWIA staff suggest that a 1-in-50 year PML, calculated using the same models as the 2025 PML, would fall to approximately $3.781 billion. Depending on the specific risk models employed, this figure could range from $3.5 billion to $4.9 billion, suggesting a potential halving of required risk transfer, including catastrophe bonds and traditional reinsurance, for 2026.
The newly enacted Texas legislation also introduces provisions for increased state-funded financing, allowing for up to $2 billion in pre- and post-event funding. This aims to reduce TWIA's historical reliance on public securities, which typically constituted a significant part of its loss funding provisions, amounting to roughly $2 billion in 2025. This new state mechanism could further diminish the need for traditional reinsurance and catastrophe bonds. During recent internal meetings, TWIA staff projected a potential decline of 25% or more in reinsurance expenses under the new 1-in-50 year loss funding scenario. Consequently, TWIA’s Actuarial & Underwriting Committee has advised against any rate adjustments for 2026 policies, citing the anticipated reduction in reinsurance costs as a primary factor. While this recommendation awaits Board approval, it signals a strong likelihood of stable policy rates for the upcoming year, reinforcing the expectation of reduced reinsurance and catastrophe bond procurement. Given that TWIA’s catastrophe bonds are multi-year instruments, approximately $1.95 billion of catastrophe bond-backed reinsurance will remain in force for the 2026 hurricane season, regardless of the final PML level set. This inherent continuity offers a degree of certainty amidst the ongoing changes in funding requirements. However, the overall demand for new reinsurance and catastrophe bonds is expected to diminish considerably, leading to substantial expense reductions for the association and potential benefits for policyholders through more favorable rates.
The shift in statutory requirements for TWIA's loss funding is expected to fundamentally reshape its risk management strategy. This legislative adjustment is projected to substantially decrease the association's dependence on new reinsurance and catastrophe bond placements. While the multi-year nature of its existing catastrophe bonds offers a stable foundation, the overall trajectory points towards a more streamlined and cost-efficient approach to risk transfer for the future.
