Chubb Outlines Structure of $20B Gulf Reinsurance Facility, Now Including Liability Cover

March 23, 2026 by

Chubb outlined the structure of the new $20 billion maritime reinsurance facility, created to provide marine war risk insurance for ships sailing through the Strait of Hormuz — which has been effectively closed to shipping since the start of the war with Iran.

The maritime insurance facility was created by the U.S. government via the U.S. International Development Finance Corp. (DFC), which on March 11 announced Chubb as lead underwriter for its $20 billion reinsurance plan.

Originally, the DFC program was focused on hull & machinery and cargo — but Chubb announced on Friday, March 20 that it has been expanded to include liability.

Moody’s said recently that exclusion of liability would be a deal-killer for most shipowners moving crude oil through the Strait of Hormuz, due to the massive risk of pollution liability and cleanup if a vessel was hit by a mine or drone.

A Moody’s representative said additional details about this incarnation of the DFC program are not yet available and therefore the ratings agency wouldn’t comment. A Lloyd’s spokesperson also would not comment on the program. The International Underwriting Association (IUA), which represents the London company market, would not offer a comment.

It is unclear how effective the facility will prove to be as ship traffic through the Strait of Hormuz remains disrupted, with only a few Iran-affiliated vessels being able to transit the waterway, according to news reports. Military experts have warned that commercial shipping is unlikely to restart without a cease fire.

Chubb listed the details of the facility, which include:

  • Chubb, acting as lead underwriter, will manage the facility, determine pricing and terms, assume risk, and issue policies for eligible vessels and cargo. Chubb will also manage all claims.
  • The initiative is a public-private partnership between DFC, Chubb, and other name-brand American insurance companies who will act as reinsurers. “Participating insurers bring deep underwriting experience in marine and marine war coverage,” said Chubb. (Editor’s note: It is unclear whether Lloyd’s and the London market could participate in the program as reinsurers).
  • DFC will help coordinate the consortium of American reinsurers and set certain criteria for ships accessing the program. (Editor’s note: AIG did not respond to a query about the requirements needed to access the cover).
  • The facility will provide war marine risk insurance for hull & liability as well as cargo. Coverage will be offered for war hull risk insurance, for war P&I insurance and war cargo insurance.
  • The offering will apply to vessels that meet eligibility criteria provided by the U.S. government.
  • This insurance will be available to ships transiting the Strait of Hormuz and only under certain conditions.
  • The additional American insurance companies will be disclosed in the coming days.
