The bill establishes the Natural Disaster Risk Reinsurance Program inside the Department of the Treasury to provide a federal backstop for property insurance losses from non-flood natural disasters occurring on or after January 1, 2026. Participation is voluntary for states; the program pays a participating state the portion of aggregate industry insured losses that exceed a state-specific trigger amount and requires the state to repay those funds within 10 years.
The statute delegates trigger-setting and loss assessment work to the National Academy of Sciences (NAS), authorizes the Secretary to issue Treasury-guaranteed bonds to fund payments, and requires participating states to submit approved plans, data on premiums and claims, and to pledge full faith and credit for repayment. For insurers, regulators, and capital markets the bill shifts extreme catastrophe tail risk into a hybrid federal–state financing structure, with implications for premiums, private reinsurance demand, and state fiscal exposure.
At a Glance
What It Does
The Treasury pays participating states the aggregate insured losses that exceed a state trigger for a given covered event. Triggers are proposed by the National Academy of Sciences, reviewed by Treasury, and represent either total direct written premium or an amount sized to protect insurers against an event with at least a 2% annual chance. The Secretary issues Treasury-guaranteed bonds to fund payments and requires states to repay within 10 years with interest covering borrowing costs.
Who It Affects
Admitted and eligible surplus-line insurers that write homeowners and residential property insurance, state insurance regulators that must collect and share premium/claims data, participating state treasuries/legislatures that must pledge repayment capacity, and reinsurers and catastrophe modelers that price and supply private tail risk. Homeowners in participating states may experience changes in coverage availability and pricing.
Why It Matters
The bill creates an explicit federal role in reinsuring extreme non-flood disaster losses, replacing pure private-market solutions with a contingent public backstop. That changes how capital providers, rating agencies, and regulators evaluate catastrophic risk, and it creates a new contingent fiscal exposure — concentrated in participating states and the Treasury's borrowing program.

What This Bill Actually Does
The bill sets up a federal reinsurance program administered by the Treasury that is available only to states that opt in and meet a Secretary-approved plan. A qualifying plan must ensure insurers cover claims up to the state’s trigger amount, provide data flows from insurers to the state regulator and then to Treasury, allocate any federal payments among insurers by market share and losses, and include a pledge of the state’s full faith and credit to repay funds the state receives under the program within 10 years.
For each covered natural disaster (defined broadly to exclude floods covered by the National Flood Insurance Program), the National Academy of Sciences proposes state-level trigger amounts for each type of event. Treasury reviews and approves those triggers; NAS must reassess triggers at least every 24 months.
When aggregate industry insured losses in a participating state exceed the approved trigger for that event type, Treasury pays the excess to the state. Payments are usually delivered in roughly four installments (about 25 percent each) as Treasury refines loss information.To fund those payments, Treasury issues bonds fully guaranteed by the United States; interest on those bonds is set at or above the recent average yield on comparable-maturity Treasury debt, and interest and the bonds are exempt from state and local taxation.
Participating states must repay the payments to Treasury within 10 years and cover interest sufficient to offset Treasury’s borrowing cost. The Secretary may audit claims, require extensive data (including premium rates compiled via NAIC), consult the Federal Insurance Office and NAIC, and prescribe implementing regulations.
Annual and final reporting by state insurance regulators to Treasury are required during the repayment period.
The Five Things You Need to Know
Participation is voluntary — a state must submit and secure Secretary approval for a plan before joining and must give 180 days’ notice to terminate.
Triggers are set using NAS work: for each state and event type the trigger is the lesser of total direct written premiums or an amount sized to protect insurers against an event with a 2% annual exceedance probability.
Treasury pays a participating state the aggregate insured losses above the trigger and may make payments in approximately 25% installments as losses are assessed.
Treasury funds payments by issuing Treasury-guaranteed bonds that are tax-exempt at state and local levels, and participating states must repay all federal amounts within 10 years with interest covering Treasury’s borrowing costs.
The Secretary may not delegate certification of whether a covered event occurred — that determination is reserved to the Secretary alone.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Provides the Act's short title: the Natural Disaster Risk Reinsurance Program Act. This is administrative but signals the statutory purpose: a reinsurance-style federal program for natural disaster risk.
Program establishment, participation rules, and state-plan requirements
Creates the Natural Disaster Risk Reinsurance Program within Treasury for events on or after January 1, 2026; makes participation voluntary and requires a Secretary-approved state plan. The plan must ensure insurers cover losses up to the state trigger, provide timely insurer-to-regulator-to-Treasury data, allocate federal payments among insurers by actual losses and market share, pledge state full faith and credit for repayment over a 10-year schedule, and address treatment of residual-market insurers. Practically, this forces states to align legislation or administrative practice with the program’s operational and fiscal commitments before joining.
Payments, trigger-setting, NAS role, and bond financing
Authorizes Treasury to pay a state the aggregate insured losses exceeding the state’s trigger for a covered event, and to make those payments in installments as losses are assessed. The National Academy of Sciences is contracted to propose triggers and conduct insured-loss assessments; triggers are subject to Treasury review and are revised at least every 24 months. Treasury finances payments by issuing bonds guaranteed by the U.S., sets interest at market-comparable yields, and exempts those bonds from state/local taxation. This structure combines model-driven loss thresholds with federal borrowing to smooth catastrophic payouts.
State repayment obligation
Requires each participating state to repay amounts received from Treasury within 10 years, together with interest sufficient to cover Treasury’s borrowing costs. States pledge full faith and credit and must provide a regular payment schedule; repayments flow into the general Treasury fund. The statutory repayment requirement creates an explicit contingent liability on a state's balance sheet when it participates.
Reporting requirements
Imposes annual reporting obligations on state insurance regulators for any covered event that produced Treasury payments until full repayment, including current insured-loss estimates, expected additional losses, timing, and repayment progress; requires a final report upon full repayment. Those reports are inputs for Treasury oversight, bond sizing, and further actuarial assessment.
Administrative powers, data collection, and definitions
Gives the Secretary broad investigatory, regulatory, and contracting authority to run the Program; mandates coordination with FIO and consultation with NAIC. The Secretary can require insurers to provide premium-rate information to NAIC for Treasury use. Definitions section clarifies covered insurance (residential property lines), covered events (non-flood natural disasters certified by the Secretary), insurers eligible for inclusion, and other operational terms. The Secretary’s discretion over data collection and audits is a practical lever to enforce program integrity.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Admitted property insurers in participating states — they receive a formal federal backstop for extreme aggregate losses, which reduces insolvency risk and can preserve underwriting capacity after catastrophic events.
- Homeowners and renters in participating states — by reducing insurer insolvency risk and supporting market capacity the program aims to keep residential property insurance available and potentially more affordable than in a pure private-market contraction scenario.
- State insurance regulators and treasuries — they gain access to NAS loss assessments and federal funds to stabilize claim payments, along with enhanced data from insurers that supports regulatory oversight.
- Secondary markets and mortgage lenders — by stabilizing insurance availability and claims payments, the program reduces short-term counterparty and collateral risk for mortgage portfolios and related securities.
Who Bears the Cost
- Participating states and their taxpayers — states must pledge full faith and credit to repay federal payments within 10 years, creating a contingent fiscal obligation that could require budgetary adjustments or new revenue measures.
- Federal taxpayers — Treasury-guaranteed bonds create contingent federal exposure; while states repay principal and interest, the federal government carries upfront borrowing and credit risk until repayment is complete.
- Private reinsurers and capital providers — they may face compressed demand or downward pressure on pricing for very large-layer reinsurance if market participants expect a federal backstop, altering private capacity and market dynamics.
- Insurers and carriers — they must supply detailed claims and premium data, accept state plan allocation rules for federal payments, and may see regulatory or market pressure to modify underwriting and pricing in response to program incentives.
Key Issues
The Core Tension
The bill trades insurer solvency and near-term insurance availability for contingent fiscal exposure and potential market distortion: it buys stability and affordability by centralizing catastrophic tail risk with the federal government and participating states, but in doing so it raises moral hazard, relies heavily on complex modeling, and creates repayment obligations that could stress state finances.
Key implementation questions and trade-offs center on modeling accuracy, timing, and moral hazard. The program relies on the National Academy of Sciences to size triggers tied to a 2% annual-chance event; those model outputs determine when federal support kicks in.
Catastrophe models are inherently uncertain and sensitive to assumptions about exposure, vulnerability, and climate trends — small changes in modeling can materially change which losses trigger payments and the fiscal size of the program. Frequent 24-month revisions reduce stale assumptions but invite political pressure and operational churn.
The bill balances prompt federal liquidity (payments in installments funded by Treasury bonds) against the need for accurate loss tallies; rushing payments increases the chance of overpaying, while slow payments undermine the program’s market-stabilizing purpose. Requiring states to pledge repayment helps limit moral hazard but shifts significant fiscal risk to state budgets; uneven repayment ability across states could create political and legal friction.
Finally, the Secretary’s broad discretion (including sole authority to certify covered events) centralizes decision-making in Treasury and concentrates implementation risk on a federal official whose criteria and processes will matter greatly to insurers, states, and markets.
