Strait of Hormuz Crisis 2026: Over 200 Tankers Trapped in Persian Gulf Amid Escalating Conflict and Insurance Withdrawals

The escalating conflict involving Iran, the United States, and Israel has severely disrupted maritime traffic through the Strait of Hormuz, a vital chokepoint for global energy supplies. Reports indicate that more than 200 tankers are currently trapped within the Persian Gulf, unable to exit safely due to heightened security threats and operational challenges.

Sharp Decline in Strait Transits

Data from maritime tracking firms like Kpler reveals a dramatic reduction in vessel movements. Since late February 2026, tanker traffic has plummeted by over 75-80% compared to previous days. Eastbound crossings tied to Middle East exports dropped to just a handful on March 1, carrying minimal volumes of crude oil, diesel, and other products—far below normal levels of 20,000+ kilobarrels daily.

Primarily Iranian and Chinese-affiliated vessels continue limited transits based on AIS signals, while mainstream commercial operators have largely halted operations. Major shipping lines, including those handling LNG from Qatar, have suspended passages, with no new LNG carriers reported since February 28 afternoon.

Vessels Stranded and Exposure Zones

Kpler monitoring as of early March 2026 identifies around 700 non-Iranian tankers in designated high-exposure areas:

• Persian Gulf (west of the Strait)
• Gulf of Oman (immediately east)
• Arabian Sea (further east)

This positioning reflects ongoing loading activities inside the Gulf paired with severely restricted outflows through the chokepoint. Additional reports suggest broader impacts, with hundreds of vessels—including container ships—anchored or idling in surrounding waters, amplifying regional congestion.

Insurance and War Risk Challenges

Several P&I Clubs within the International Group have issued notices to terminate war risk coverage for vessels entering the Persian Gulf, adjacent waters, or Iranian territories, effective from March 5, 2026. This represents a complete withdrawal of standard protection rather than adjusted pricing.

Underwriters anticipate rapid escalations in premiums for any remaining operations in the area, potentially reaching the higher limits of established ranges (around 0.5% net, with some sources noting doubling from prior levels). Coverage may become unavailable for certain transits, forcing operators to weigh self-insurance against substantial liabilities—a step few can sustain long-term.

Additional measures include shortened notice periods for cancellations (potentially down to 48 hours in extreme cases) and tighter terms overall.

Expert Assessments on Risks and Outlook

Industry voices highlight that prolonged disruption poses greater concern than brief spikes. BIMCO’s safety and security analysis suggests Iranian forces retain asymmetric capabilities (e.g., mines, drones) to deter shipping, even after recent strikes on their assets.

While a formal, legally enforced closure has not occurred, the environment—marked by vessel attacks, crew risks, and broadcast warnings—has created a de facto halt for most commercial traffic. Expectations point to eventual U.S. naval efforts to restore secure passages, though timelines remain uncertain.

Greece, a major flag state, reports significant exposure with hundreds of linked vessels in the broader region and a smaller number still inside the Gulf.

Broader Implications for Energy Flows

The near-standstill affects roughly one-fifth of global oil and substantial seaborne gas volumes. LNG movements have evaporated in the corridor, with Qatari carriers rerouting to Europe and Asia. Ports in the Middle East face operational strains from missile incidents and slower clearances.

This situation underscores the Strait of Hormuz‘s critical role in worldwide energy security, with ongoing developments closely monitored for potential resumption or further escalation.
