Berkshire Hathaway Joins Persian Gulf Insurance Pool

Berkshire Hathaway , led by CEO Greg Abel, has entered a U.S. government-backed insurance syndicate designed to cover vessels moving through the Strait of Hormuz, a maritime corridor described as high risk. The development was announced on April 3 and centers on expanding insurance capacity for commercial shipping in an area tied to global energy flows.

Officials said the initiative increases the U.S. International Development Finance Corporation’s (DFC) reinsurance commitment to $40 billion . The stated purpose is to support continued commercial transit through the strait, which handles about 20% of global crude oil traffic. The coverage is aimed at ships operating in a region where insurers have not consistently offered certain protections.

The syndicate is led by Chubb and includes AIG, Travelers, Liberty Mutual, Starr, CNA, and Berkshire Hathaway’s National Indemnity subsidiary. The group is offering war hull risk insurance, protection and indemnity coverage, and cargo insurance that the source material says had not been available for vessels operating in the region. The DFC said participating insurers have extensive experience in marine and war risk underwriting.

For Berkshire Hathaway, the participation through National Indemnity marks a change from prior leadership’s approach, which historically avoided underwriting war-risk exposure of this scale in active conflict zones. The move places Berkshire alongside major global insurers in a program explicitly structured around government-backed reinsurance support.

Separately, Berkshire Hathaway’s National Indemnity subsidiary took a 2.5% stake in Japan’s Tokio Marine Holdings for $1.8 billion in late March. The source material says National Indemnity has authorization to raise that holding to 9.9% . The investment also includes a Whole Account Quota Share arrangement that adds National Indemnity to Tokio Marine’s reinsurance panel and assigns it a portion of Tokio Marine’s global risk portfolio.

Together, these steps indicate a push to broaden Berkshire Hathaway’s insurance footprint internationally under Abel’s leadership, while taking on exposures tied to marine, war risk, and global reinsurance portfolios. The immediate market relevance is linked to shipping continuity through the Strait of Hormuz and the availability of insurance products that can affect whether vessels and cargoes move under commercial terms.

Key uncertainties include how much capacity the syndicate will ultimately deploy and how demand for the newly offered coverages develops for vessels operating in the region. The source material does not specify pricing, volumes of insured voyages, or the duration of the DFC-backed arrangement.
