Renewal Options for Terrorism Risk Insurance Act (TRIA)



With the federal Terrorism Risk Insurance Act (TRIA) backstop set to expire in 2027, Congress is currently evaluating options for its renewal and potential redesign to address new risks and market dynamics.

The Congressional Research Service (CRS) has released a comprehensive report outlining key policy considerations for lawmakers as the reauthorization discussion unfolds. TRIA, originally enacted in response to the insurance industry's reluctance to cover terrorism risks after the September 11 attacks, provides a critical safety net by reimbursing insurers for a portion of losses from certified terrorist events. This program covers commercial property and casualty insurance, but notably excludes life, health, and personal lines policies.

Understanding TRIA's Impact on the Insurance Market

Since its inception in 2002 following a major market disruption post-9/11, TRIA has been a pivotal mechanism for ensuring the availability and affordability of terrorism coverage. The CRS's report highlights that insured losses from September 11 are estimated at approximately $60 billion today, illustrating the significant financial stakes involved. Despite the absence of any certified terrorist attacks triggering federal payments under TRIA, the program's steady uptake—ranging from 60% to 80% according to Treasury analyses—demonstrates its importance to the insurance industry.

Key Issues in Reauthorization

The CRS report identifies four main issues facing TRIA's reauthorization: evaluating the necessity of the program, determining the appropriate level of private sector risk retention, addressing the threats posed by nuclear, chemical, biological, or radiological events, and considering how to best approach cyberterrorism risks. These discussions are timely, given that premiums for TRIP-eligible lines reached $314.1 billion in 2024, according to treasury data.

Bill Name Sponsor Proposal
H.R. 7128 Rep. Mike Flood (R-NE) Extension to 2034
$10M Loss Threshold from 2029
S. 4395 Sen. Dave McCormick (R-PA) 7-Year Extension
No Additional Changes

Legislative Options on the Table

Currently, two bills are presented in Congress, each proposing different paths for TRIA's future. H.R. 7128, reported by the House Financial Services Committee, seeks to extend TRIA until 2034 with a notable change: introducing a $10 million minimum insured-loss threshold starting in 2029. Meanwhile, S. 4395, introduced by Sen. Dave McCormick, offers a straightforward seven-year extension without additional modifications. These proposals reflect contrasting strategies for ensuring TRIA remains effective in the evolving risk landscape.

As TRIA's expiration looms, the insurance industry closely monitors Congress's proceedings. The eventual decision will shape not only federal participation in covering terrorism risks but also influence the broader stability and resilience of the U.S. insurance market in facing emerging threats.
