Inside the Greek Tanker Strategy: Empty Ships, 4,000x Insurance, and a $1 Million Toll

2. Hedging Against a Snap Reopening
The prize for being right is enormous. With over 150 ships anchored outside the strait at the peak of the crisis, the first commercial tanker to load and sail after a verified reopening will capture charter rates that are expected to spike dramatically . Evangelos Marinakis, the backer of Capital Maritime, confirmed in early June that his firm was pulling tankers to within three to five days' sailing distance of the Persian Gulf, explicitly as a bet on a reopening .

3. Demonstrating Capability to Oil Traders
Greek owners have a track record to protect. In late March, the Greek-managed VLCC Marathi successfully transited the strait carrying Saudi crude, becoming one of the first commercial tankers to cross since the crisis began . While some ships proceed with transponders off, these calculated crossings signal to oil traders who are desperate for reliable tonnage that Greek-managed vessels are still a viable option, even if the insurance math is brutal .

The Diplomatic Fog: A Deal Always "Imminent" but Never Done

Despite an intense drumbeat of diplomatic activity, the strait remains functionally closed. The gap between political statements and operational reality is widening.

• The White House vs. Tehran: On May 24, President Trump claimed a peace deal was "largely negotiated" and that an announcement was imminent, a statement immediately cast into doubt by an Iranian media outlet . Just days later, on June 1, Iran suspended all indirect talks with the US and threatened a full blockade in retaliation for Israeli operations in Lebanon, a move that sent oil prices climbing .
• Industry's Demand for Certainty: At an Athens shipping conference on June 1, the same day talks collapsed, executives drew a red line. Any US-Iran deal must include "clear rules" allowing vessels to resume normal operations, not just a political headline . Without unambiguous legal and security frameworks, they warned, insurers and crews will continue to balk.
• Military Posturing Without Commitment: A UK-led coalition of over 30 nations has met multiple times to plan a coordinated military reopening, but the IRGC shows no signs of relinquishing control . A full US military operation to seize the strait is considered politically unlikely under an "America First" doctrine, leaving a diplomatic resolution as the only viable path—one currently blocked by unresolved disputes over Iranian uranium enrichment .

How the Tanker Market Fractured and Routes Reconfigured

The crisis has not just disrupted shipping; it has splintered the global tanker market into two distinct classes of vessel.

The first tier is "Hormuz-capable" tonnage: vessels that fly the flag of a nation participating in a US-led naval convoy and whose hulls are backed by government war-risk insurance. These ships, often Greek, are the few that still attempt transits . Everyone else is "Hormuz-excluded"—mainstream commercial tankers whose operators and insurers refuse to enter the Persian Gulf at all.
This segmentation has forced a massive re-routing of oil flows. Vessels that would normally load in the Persian Gulf are instead making the longer journey around the Arabian Peninsula, adding 10 to 15 days of sailing time per voyage. This surge in tonne-mile demand has sucked up global tanker supply, pushing freight rates for non-Hormuz routes to multi-year highs . Meanwhile, over 200 vessels remain trapped on either side of the strait, some for more than three months, with crew changes becoming impossible, certifications expiring, and costs mounting by the day .

The Insurance Black Hole: Why Premiums, Not Missiles, Are the Real Blockade

The most impenetrable barrier to restoring normal traffic is not the IRGC's gunboats but a private insurance market that has all but vanished.

• A 4,000-Fold Price Shock: As of early June 2026, war-risk premiums for a single transit of the Strait of Hormuz had soared to approximately 4% of a ship's hull value for a seven-day policy—about 4,000 times above pre-crisis levels. For a $100 million VLCC, that means a single trip can cost $4 million in insurance alone .
• P&I Clubs Walk Away: On March 5, the industry's collective spine fractured. In a coordinated move, major International Group P&I clubs—Gard, Skuld, and NorthStandard—issued 72-hour notices canceling all war-risk coverage for the Persian Gulf and adjacent waters. This wasn't a price hike; it was a complete withdrawal of standard protection .
• The Government Becomes the Insurer of Last Resort: With private markets in full retreat, the US government has stepped in to backstop war-risk insurance for vessels participating in coalition convoys, creating a stark two-tier system where only state-backed ships can realistically operate . Vessels that manage to secure coverage face extremely tight capacity and rates that, while off their late-March peak of 2.5% of hull value, remain historically punishing .

The Critical Reality Check: Even if a political deal to reopen the strait were signed tomorrow, the tankers would not simply start flowing again. Restoring a functional insurance market is not a matter of a single announcement. It will require a sustained period of proven safe passage before the P&I clubs, Lloyd's syndicates, and their reinsurers at Swiss Re and Munich Re will return to the table. As one shipping executive warned, the strait will remain effectively closed to most commercial traffic for months after any theoretical deal . The ships might be positioned, but the insurance that lets them sail is still missing.
