Senate passes TRIA reauthorization to 2034; House event-certification threshold remains the open question

The Senate passed legislation late on Sept. 28 to reauthorize the federal terrorism insurance backstop by unanimous consent, moving the Terrorism Risk Insurance Program Reauthorization Act of 2026 to the House and proposing to carry the program past its end-2027 sunset through 2034.

Neither vote on this program has been close — the Senate Banking Committee advanced the measure 24-0 earlier in September, and the House passed its own extension in June, 373-15. The two texts, however, are not identical, so lawmakers must either compromise or adopt one version, and the industry's trade associations have pressed them to reconcile quickly, according to the Carrier Management report; the report does not spell out the other differences.

Insurers treat the program as a capital item because the backstop engages only when the Secretary of the Treasury certifies an act of terrorism and the event reaches a threshold of losses, with insurers holding deductibles and copays underneath — an arrangement the report describes as essentially a reinsurance program that lets carriers cover terrorism risk at all. Private terrorism insurance all but disappeared after the attacks on 9/11, and since TRIA followed, no certified terrorism event has triggered the program.

The calendar still carries weight precisely because no event has ever triggered the program. Insurers and policyholders are already negotiating policies that run past the end of 2027, and the industry pushed for action early to head off uncertainty and disruption in the marketplace instead of waiting out the sunset. Its stated target is a presidential signature by the end of 2026, which would leave roughly a year of runway between enactment and the current expiry.

Both chambers have approved extensions through 2034, and the House version would raise the event-certification threshold from $5 million to $10 million beginning in 2029 — the level at which a certified event begins to draw on the federal layer. The House's change would move a band of events out of certification entirely, an adjustment that surfaces in a capital model long before it surfaces in a claims file. Five million dollars is a modest bar for a deliberate attack, and doubling it is the kind of term change that gets priced into every terrorism quote that extends past the current authorization.

Reconciliation could take either of two shapes: the House could adopt the Senate text as passed and discard its own certification change, or the chambers could negotiate with the threshold, the end date and anything else that divides them on the table. The margins on both floors are wide enough to suggest the disagreement is textual, not political. The report does not say what the Senate text does with the certification bar, if anything.

Congress has renewed the program four times, in 2005, 2007, 2015 and 2019, adjusting it on each pass, and this would be the fifth, so the trade groups argued in terms that will be familiar from past renewals. Sam Whitfield, senior vice president of federal government relations and political engagement at the American Property Casualty Insurance Association, said the action "reflects strong bipartisan recognition that TRIA remains essential to maintaining economic stability, supporting investment, and ensuring the availability of terrorism risk insurance for businesses and communities across the country." Jimi Grande, senior vice president of federal and political affairs at the National Association of Mutual Insurance Companies, put the stakes in construction and development, which he said depends on terrorism coverage being available "to secure financing and create jobs." "By moving swiftly and decisively to extend TRIA and the partnership it created," he said, "the Senate is making sure those projects, and our economy, will have the protection they need."

One outstanding item is not in either text: Treasury's hybrid-attack model, as this publication argued in September, puts cyber at 88% of the loss, and the trigger for a hybrid event remains unfinished. A reauthorization that fixes 2034 and leaves the certification bar to negotiation does not close that gap.

The deadline the industry has set is the end of 2026, and the policies already being negotiated run past 2027. Whenever the chambers finish, the number carrying the capital consequence is the certification threshold: $5 million now, $10 million in the House text beginning in 2029. It is the figure that decides when a terrorism loss moves off insurer retentions and onto the federal layer, which is the decision insurers have to price for every policy they write beyond the current sunset.
