H.R. 7128 passed the US House 373 to 15 on June 29, 2026, extending TRIA through 2034 and raising the terrorism certification threshold from $5 million to $10 million beginning in 2029. The threshold change, not the extension, is the repricing event. Incidents that qualify for federal cost-sharing today fall outside the program from 2029, leaving a frequency band carriers must retain net or place in the standalone market.
Key Takeaways
- The per-carrier certification floor doubles from $5 million to $10 million in 2029, after the House Financial Services Committee first considered $25 million.
- TRIA has certified one event in its history, the September 11, 2001 attacks at roughly $47 billion of insured losses, so the newly uncovered band has no certification record to fit against.
- US standalone terrorism pricing fell 10.4% in the fourth quarter of 2025, which makes the substitute market a usable benchmark and a usable alternative at the same time.
- A carrier with $500 million of TRIA-eligible direct earned premium carries a $100 million deductible before federal reimbursement begins, so the backstop was never the whole answer.
- Total TRIP-eligible premiums reached $314.1 billion in 2024 with take-up between roughly 60 and 80 percent, which is the base being repriced.
What the Bill Actually Changes
Federal reimbursement under TRIA requires three conditions at once. Treasury must certify the incident as an act of terrorism involving a foreign person or foreign interest acting against US commerce or infrastructure. Aggregate insured losses across participating carriers must exceed $200 million. And the individual carrier's loss must exceed the per-carrier floor, currently $5 million. Once all three are met, the insurer absorbs a deductible of 20 percent of its prior-year direct earned premium in eligible lines and the federal government reimburses 80 percent above it.
That deductible is the part most often understated in pricing. It is computed on the carrier's premium base rather than on the loss, so a mid-market carrier with $500 million of TRIA-eligible direct earned premium carries a $100 million deductible. A $1 billion industry-level terrorism loss produces meaningful retained loss from the deductible alone, before the 80/20 split above it applies. The backstop reduces net retained terrorism exposure; it does not remove it, and it matters least in exactly the mid-severity certified events it is most often assumed to cover.
Total premiums across TRIP-eligible lines reached $314.1 billion in 2024, with terrorism take-up between roughly 60 and 80 percent of eligible policyholders depending on the measure. A large share of US commercial property, general liability, workers compensation, and specialty endorsements are priced on the assumption that a certifiable event will be TRIA-backed.
The extension itself resolves a separate exposure cleanly. Lenders on high-value commercial property in identified risk zones generally require terrorism coverage as a loan covenant, so a lapse would have put borrowers into technical default. Ten-year commercial mortgage loans originated in 2026 ran past the December 31, 2027 expiration, and mortgage insurance actuaries who loaded for lapse probability on those credits can now remove it.
The Band With No Loss History
From 2029, per-carrier losses between $5 million and $10 million stop qualifying for cost-sharing even when the $200 million aggregate trigger is crossed. Carriers currently treating that range as federally covered above the deductible either reprice the endorsement for full net retention or carry a layer they have not charged for.
| Per-Carrier Loss Scenario | Federal Backstop Through 2028? | Federal Backstop from 2029? | Net Change for Carriers |
|---|---|---|---|
| Below $5M | No (below current floor) | No | Unchanged |
| $5M to $10M | Yes (above $5M floor) | No (below new $10M floor) | New net carrier retained |
| Above $10M | Yes | Yes | Unchanged |
Fitting a frequency assumption to that band is the hard part. TRIA has certified one event in its history, the September 11, 2001 attacks, with insured losses of roughly $47 billion, far above any threshold in discussion. Domestic incidents in the $5 to $10 million per-carrier range carry no certification history, so credibility-weighted development is not available and the work is scenario analysis, historical domestic incidents, and comparison against international frequency curves.
The standalone market supplies the one live price signal. Private standalone terrorism responds at any severity without certification, and US capacity exceeds $2 billion per risk, with London syndicates and carriers including Munich Re and AXA XL writing $1 billion to $4 billion per risk depending on location and accumulation, and Munich Re offering limits up to $500 million per insured. Those rates run roughly 0.05 to 0.15 percent of insured value for urban commercial property.
Direction matters as much as level. US standalone terrorism pricing fell an average of 10.4 percent in the fourth quarter of 2025 on capital inflows and several stable loss years, so the participants taking first-dollar terrorism exposure with no government program behind them are doing it about a tenth cheaper than a year earlier. A TRIA-backed endorsement prices below a standalone alternative because the backstop absorbs part of the certifiable tail; the spread between them is a direct estimate of what the uncovered band is worth, and even a fraction of it is a nonzero repricing obligation across a large commercial property book.
That also makes the substitute a structural option rather than only a benchmark. Where standalone capacity fits inside the existing pricing margin, buying reinsurance for the newly uncovered band preserves the endorsement and avoids retail rate filing. Where it does not, the repricing has to happen at retail.
Who Cannot Reach the Substitute
The extension preserves TRIA above the new floor. It leaves two gaps below and beside it.
The first is market access. TRIA's mandatory offer requirement obliges every participating insurer to make terrorism coverage available regardless of size, and Treasury's Federal Insurance Office is required to study small insurer competitiveness biannually. Its 2025 study examined exactly the three factors the threshold change makes binding: mandatory availability, the effect of trigger changes on small carriers, and the availability of private terrorism reinsurance for smaller books.
For a large carrier the change is a pricing adjustment with identifiable alternatives, because aggregating terrorism exposure across a broad commercial portfolio is what buys access to the international standalone reinsurance market. For a smaller carrier writing middle-market commercial accounts, that reinsurance is effectively unavailable at actuarially sound rates, because the book lacks the premium volume to sustain a standalone terrorism program. Those carriers keep the mandatory offer obligation and lose the backstop in the $5 to $10 million band with no substitute to buy.
The second gap is definitional. H.R. 7128 extends the statutory framework through 2034 without revisiting the certified act definition written in 2002, which requires attribution to a foreign person or foreign interest deliberately targeting US commerce or civilian infrastructure. That language predates large-scale AI data centers and interconnected computing infrastructure now concentrating substantial insured commercial property value in the same corridors where terrorism exposure already clusters. Severity is not the issue: such an incident could clear the $200 million aggregate trigger comfortably. Attribution is, and a certification that stalls on attribution leaves the carrier holding a loss the endorsement was priced as though Treasury would share.
