Shipping Groups: Hormuz Traffic Won't Normalize Until Mines Are Gone and TSS Restored

Shipping industry bodies told markets on June 19, 2026 that maritime traffic through the Strait of Hormuz will not return to normal until all mines are removed and the Traffic Separation Scheme (TSS) is reinstated — a condition that puts the weight of normalization squarely on the pace of mine-clearance operations still underway.

The statement, coordinated across major industry associations, lands two days after a US-Iran memorandum of understanding was announced on June 17. The 14-point MoU commits both sides to further talks on a final agreement within 60 days and provides for the eventual release of an estimated $24 billion in Iranian funds frozen in accounts worldwide. It is a political signal, not a physical one — and the industry's message is that the strait's operational status will track mine-clearance progress, not diplomatic calendars.

INTERTANKO has reported approximately 80 mines in the strait. That figure is significantly higher than the "roughly a dozen" cited by Reuters sources in March, reflecting either an escalation in mining activity or wider survey coverage since operations began. Either way, it is the more recent and authoritative figure for operational planning purposes.

The Clearance Problem

U.S. Central Command launched mine-clearance operations on April 11, 2026, initially deploying two guided-missile destroyers. The Navy has since planned to expand those operations with drone-based countermeasures — autonomous systems capable of searching both the sea floor and the surface — according to reporting from June 16. The shift toward unmanned platforms is deliberate: Reuters noted in April that mine-clearing crews remain exposed to Iranian attack during operations, making drone-led MCM (mine countermeasures) both a tactical and a force-protection preference.

The timeline is unforgiving. Reuters reported on June 15 that a full survey and clearance of the strait could take weeks even after a deal framework is in place. With the MoU now signed and a 60-day negotiating clock running, that window matters: if clearance operations lag, commercial shipping will remain on alternative routing regardless of what diplomats agree.

The multinational dimension is significant. The EU's Aspides naval mission proposed in early June to take the primary MCM role in the strait. British mine-hunters prepared to deploy by late May. The IMO has called for coordinated, organized clearance and collision-avoidance protocols. INTERTANKO issued a call for a coordinated approach as early as April 17, and the joint guidance from INTERTANKO, IMCA, and OCIMF published in May set out transit protocols for vessels operating during the restricted period.

The coordination question is not trivial. Multiple naval task groups — U.S., European, and British — operating in confined, mine-dense waters without a unified command structure creates deconfliction risk of its own. The IMO's call to avoid vessel collisions is a reminder that the clearance phase carries its own hazards independent of Iranian action.

Stakes for Energy Markets

The Strait of Hormuz is the single most consequential maritime chokepoint for global oil and LNG flows, transiting roughly 20 percent of the world's seaborne petroleum trade. Every day of restricted TSS operation extends the duration of alternative routing — via Cape of Good Hope or Sumed pipeline diversions — adding freight costs, voyage time, and tanker demand that have already repriced freight markets since the closure began.

Shipping industry groups made explicit on June 19 that restoration is conditional, not automatic. The MoU may reduce Iranian incentive to impede clearance operations, and the prospect of $24 billion in unfrozen assets gives Tehran a material stake in follow-through. But the physical constraint — 80 mines across one of the world's narrowest strategic waterways — does not dissolve with a signature.

The 60-day diplomatic clock and the clearance timeline are now running in parallel. Whether they converge will determine how quickly freight rates, LNG premiums, and regional energy security calculus normalize — or don't.
