The Trump administration rolled out a $20 bn maritime reinsurance program aimed at stabilizing shipping through the Strait of Hormuz.
The plan targets hull and machinery, along with cargo risks. It does not include liability coverage. That gap raises concerns across the insurance market.
The U.S. International Development Finance Corporation announced the program on March 6. Officials framed it as a step to restore confidence in maritime trade and support allied businesses operating in the region.
On March 11, Chubb was named lead partner. The structure leans on public backing with private market execution. War-risk rates in the Strait of Hormuz climb to 3% of hull value as DFC launches $20bn reinsurance plan amid tanker strikes
Moody’s Ratings questions whether the program goes far enough.
The initiative helps but does not fully address current risk conditions. Shipowners still face exposure that insurance does not cover. That changes decision-making quickly.
Even with coverage in place and military escorts available, operators remain cautious. Serra pointed to ongoing safety concerns in the Strait.
Incentives remain weak while conflict risk stays elevated. Movement through the corridor depends on perceived safety, not only insurance availability.
Fitch Ratings expects the withdrawal of hull war-risk marine insurance in the Persian Gulf to carry negative credit implications for U.S. property and casualty insurers.
Liability risk sits at the center of the issue. A damaged oil tanker could trigger large-scale environmental loss. Coastal areas such as Dubai face exposure from potential spills.
Cleanup costs and third-party claims could escalate rapidly. Without liability protection, insurers and shipowners carry open-ended risk. It shows government willingness to intervene and reduces expectations of a prolonged conflict. Still, the structure leaves gaps that limit immediate impact on shipping activity.
The scale of exposure remains high despite a limited number of incidents. Around 20 vessels have been attacked so far during the conflict.
Estimates suggest at least $25 bn in vessel value remains trapped in the Persian Gulf. Some projections push worst-case exposure toward $40 bn.
Roughly 1,000 vessels are believed to remain in the region. Data remains uneven, drawn from public reports and insurer discussions. Around 20,000 seafarers remain on board those ships. Movement remains constrained as risk conditions persist.
The insurance sector has capacity to absorb losses at this scale. Recent hurricane losses in 2024 reached about $50 bn and were absorbed across global carriers.
Marine risk differs in structure. Exposure concentrates among fewer players compared with catastrophe risk.
Large diversified insurers and reinsurers hold capacity and maintain strict limits. They can manage aggregate losses across portfolios.
Smaller marine-focused insurers face higher concentration risk. Losses hit harder when exposure pools remain narrow.
According to Beinsure analysts, coverage gaps in liability often shape market behavior more than hull or cargo protection. Without that layer, capital support alone rarely shifts risk appetite fast.
The program leaves open the question of expansion. The DFC has not confirmed plans to add liability coverage.
Until that changes, insurers and shipowners continue to weigh risk carefully. Movement through the Strait remains constrained under current conditions.
