Terrorism Risk Insurance Act Reauthorization and the 2027 Program Sunset
Few federal programs operate as quietly as the Terrorism Risk Insurance Act — until the calendar forces the conversation. TRIA, enacted after the attacks of 2001 and last reauthorized in 2019, is scheduled to sunset on December 31, 2027. For a commercial property owner signing a multi-year lease, or a developer financing a project that will not deliver until 2028, that date has stopped being distant. It sits inside the term of decisions being made right now.
In 2026 the reauthorization moved further than it has in years. The House passed H.R. 7128 on June 29, 2026 by a 373 to 15 vote, and the Senate passed its companion, S. 4395, by unanimous consent on September 28, 2026. Both bills would extend the program seven years, to 2034. The House version would also raise the threshold for certifying a terrorist act from $5 million to $10 million beginning in 2029 and add notice requirements to the Treasury certification process. The important caveat is that neither bill has been enacted — until the chambers reconcile and the President signs, the program still expires at the end of 2027.
It helps to remember what TRIA actually is. It is not an insurer; it is a federal backstop that shares catastrophic terrorism losses with the private market. The program activates only when aggregate insured terrorism losses exceed a $200 million trigger. Above that, each participating insurer retains a deductible equal to 20 percent of its premiums on TRIP-eligible commercial lines, and the Treasury then reimburses 80 percent of losses above that deductible. The industry carries an aggregate retention of roughly $53.3 billion before taxpayer dollars are net exposed, and the government recoups a portion afterward through a policyholder surcharge capped at 3 percent. The backstop caps the tail; it does not write the policy.
That structure shapes the private market more than most buyers realize. Because TRIA requires insurers to make terrorism coverage available on commercial property and liability policies — the "make available" mandate — terrorism cover is widely offered and frequently embedded in the base policy, with the buyer free to reject it in writing. The backstop is the reason capacity exists at a price most middle-market buyers can absorb, and the reason a financed development can be insured against terrorism almost as a matter of course. Remove it, and the economics that keep that coverage broadly available and affordably priced change in a single stroke.
Marsh's monitoring shows terrorism take-up rates drifting lower over the past five years, which can make the coverage feel optional. It is not optional everywhere. In dense urban cores and for trophy or landmark assets, the exposure is concrete, and lenders routinely require terrorism coverage as a loan covenant. Workers' compensation carries no terrorism exclusion at all, so for an employer with concentrated payroll in a single building, terrorism is an unavoidable exposure regardless of what the property schedule says.
The exposure that deserves attention in 2026, though, is contractual and structural rather than hypothetical. Many property and general liability policies contain conditional terrorism exclusions — language that lies dormant while TRIA is in force and springs the coverage away the moment the program lapses. A multi-year policy bound today can contain a provision that rewrites itself at the sunset. If terrorism coverage is also a financing requirement, a sudden lapse could put a borrower in technical default on a loan that has nothing to do with an actual attack. The risk is not only an event; it is a gap that opens on a date certain.
This is precisely the analysis our 4-Step Strategic Process is built to run. Strategic Discovery identifies which policies carry TRIA-conditional language and where terrorism coverage is written into a lease or loan covenant. Risk Assessment measures the real concentration across property, business interruption, and workers' compensation against the backstop's parameters. Solution Design decides whether embedded TRIP coverage, a standalone terrorism policy, or a captive layer is the more intentional structure for a given portfolio. Ongoing Optimization tracks the reauthorization through its resolution so the client is never surprised by the calendar.
A program that may well be extended to 2034 is not a reason to stop watching it. It is a reason to read the fine print now, while there is time to act on it. The owners who will be insulated from the 2027 sunset are not the ones who assumed Congress would handle it. They are the ones who made certainty of coverage a term of their contracts years before the deadline, rather than a question asked after it had already passed.
