The US House of Representatives has approved a seven-year extension of the Terrorism Risk Insurance Program, securing federal backstop coverage for commercial property-casualty insurers through December 31, 2034. The chamber passed H.R. 7128, the TRIA Program Reauthorization Act of 2026, by a vote of 373–15, according to the US Chamber of Commerce. The legislation now advances to the Senate, where a companion bill is already in committee, and the lopsided margin signals that the structural case for a federal backstop remains as compelling as ever.
A 373–15 vote that reflects two decades of market dependency
Before reaching the House floor, the bill cleared the House Financial Services Committee 51–2 on January 22, 2026 — a bipartisan signal that no credible political coalition exists to let TRIA lapse. The program’s track record makes the arithmetic straightforward: from 2003 through 2023, Treasury estimates that insurers collected roughly $68.3 billion in terrorism insurance premiums under the TRIA umbrella, building a market that would not otherwise exist at commercial scale. TRIA, currently set to expire at the end of 2027, has been reauthorized by Congress four times since its 2002 enactment, and those prior extensions came in 2005, 2007, 2015, and 2019. H.R. 7128 would add a fifth reauthorization, extending coverage by seven years.
The Insurance Information Institute has consistently supported TRIA reauthorization, as has virtually every major commercial lines trade body. Under current law, a single event must generate at least $5 million in insured losses before it can be certified as a terrorism act, and industry-wide annual losses must exceed $200 million before the federal backstop activates. Both thresholds are structural guardrails that limit moral hazard while ensuring meaningful coverage.
Why $4 billion of private capacity cannot replace a $100 billion backstop
The core market-failure argument for TRIA has not changed since 2002, but the 2026 data from Marsh makes it concrete. Private reinsurers can deploy between $1 billion and $4 billion of per-risk terrorism capacity, depending on the location insured — a figure that sounds large until it is placed beside the federal program’s $100 billion aggregate cap documented by the Congressional Research Service. At peak, private capacity covers, at best, four cents on every dollar of federal protection. For trophy towers in Manhattan, major sports venues, or dense urban infrastructure where a single mass-casualty event could simultaneously impair dozens of policy limits, that gap is not a rounding error — it is the entire ballpark.
The demand side confirms the dependence. Estimates for the terrorism coverage take-up rate among commercial buyers range from around 60% to nearly 80%, and total premiums across all TRIA-eligible lines reached $314.1 billion in 2024. The NAIC has stated that sustaining a viable private market for terrorism insurance depends on a federal backstop in the absence of equivalent private-market innovations. Without TRIA, most of that premium volume would simply evaporate: carriers would exclude the peril rather than absorb tail risk they cannot retrocede.
This dynamic is directly relevant to the debate around standalone cyber war cover for state-sponsored attacks, a market that faces an analogous capacity-to-exposure mismatch. Terrorism and cyber war share the same fundamental problem: losses can be instantaneous, correlated across geographies, and far larger than any single carrier’s balance sheet can absorb.
The 2029 certification threshold change that most buyers will miss
Buried in H.R. 7128 is a provision that deserves closer scrutiny from risk managers: a scheduled increase in the minimum event-loss threshold required for a federal certification. Under current law the floor sits at $5 million; the bill raises it to $10 million in 2029. On the surface this looks modest, but the practical effect is to remove smaller domestic terrorism incidents from the federal mechanism entirely, pushing coverage of those events back onto individual carrier balance sheets or, more likely, leaving them in policy exclusions.
Risk managers at mid-market commercial accounts — where property values and terrorism coverage limits are often relatively modest — should model whether a $10 million aggregate event threshold meaningfully changes the probability of certification for the attacks most likely to affect their assets. A car-ramming at a regional shopping center, a pipe bomb at a local transit hub: these events can produce significant business interruption losses without clearing the new $10 million bar. The threshold change is not retroactive, but from 2029 onward it will quietly redefine the coverage perimeter for a subset of commercial buyers.
The pattern resonates with regulators outside the US. APRA’s minimum expectations for insurer readiness to geopolitical shocks reflect a comparable effort to define the boundary between government-absorptive and market-absorptive risk — a line that shifts with every new piece of legislation and every new threat vector.
Treasury’s 90-day clock and what it means for claims certainty
H.R. 7128 introduces a procedural change that the insurance industry has long lobbied for: a statutory 90-day deadline for Treasury to issue a final terrorism certification determination after public notice. This matters because the existing statute imposes no time limit on certification, creating uncertainty about whether a given event will qualify for the backstop — and therefore whether reinsurers can book recoveries and cedants can release reserves.
A hard 90-day window does not guarantee faster claims payments, but it does cap the ambiguity period. For captive managers and corporate risk officers structuring multi-year terrorism programs, that certainty has real option value: it defines the maximum period of policy-limit uncertainty following a declared event. The US Chamber of Commerce’s formal support letter for H.R. 7128 cited this provision among the bill’s key improvements over the existing statute.
Senate action remains the critical path. Senator David McCormick (R-PA) introduced companion bill S. 4395 on April 27, 2026, which has been referred to the Senate Banking Committee. Given that the House passed H.R. 7128 with only 15 dissenting votes, Senate leadership will face limited political cover for delay. The existing program does not expire until the end of 2027, but market participants — particularly commercial real estate lenders requiring terrorism coverage as a loan covenant — will want Senate confirmation well before that date to avoid coverage uncertainty in renewal negotiations. For the broader picture of natural catastrophe and systemic risk protection gaps, the TRIA debate sits squarely within the framework of Moody’s climate risk and North America’s protection gap: federal backstops increasingly serve as the load-bearing wall between insurable and uninsurable risk.
For (re)insurers, the seven-year runway to 2034 is long enough to restructure terrorism reinsurance treaties without emergency repricing, but short enough to remind the market that the next reauthorization debate will arrive before the decade is out. Those who remember the coverage freeze in the months after the 2001 terrorist attacks — before Congress enacted TRIA in November 2002 — will not need reminding of what the backstop’s absence looks like. The NAIC’s overview of the Terrorism Risk Insurance Act catalogues that history for those who do.
