World's Largest Tanker Operator: Hormuz Disruption May Extend to 2027
nashnova research
Mitsui OSK Lines, the world's largest tanker operator, says Strait of Hormuz shipping is unlikely to resume this year — disruption now expected to extend into 2027, leaving the world's most critical oil chokepoint effectively shut.
What did Mitsui OSK Lines say?
CEO Jotaro Tamura told Bloomberg on Thursday that a return to normal operations this year is highly unlikely.
His words: "Given the current situation, it is hard to foresee any form of resumption before year-end."
This means → The world's largest tanker company is now planning around disruption lasting at least into 2027 — not a verbal worry, but a judgment baked into its quarterly earnings assumptions.
Why is the earlier timeline dead?
Mitsui's earnings report last month assumed Hormuz shipping would resume gradually from October 2026 and normalize by January 2027.
This week, the U.S. and Iran exchanged strikes for the first time in over a month, sharply escalating tensions.
In plain terms = The "earliest October reopening" forecast set just last month was blown apart by this week's military escalation. The timeline has to be pushed back again.
What is Mitsui's red line?
Tamura said "the current situation continues to far exceed our acceptable risk level" — the company has no plans to resume oil shipments through Hormuz.
Conditions for return: a substantive de-escalation, plus verifiable guarantees of sustained safe passage.
This reflects a stark calculation — even the world's largest tanker operator would rather walk away from the revenue than take the risk. That is not caution; it is outright avoidance.
What does the strait look like now?
Since this week's re-escalation, observable daily transits through Hormuz have plunged to just a handful of vessels.
However, "dark fleet" ships — tankers that switch off tracking systems and sail unannounced — have increased in recent weeks, helping some Persian Gulf crude find alternative export routes.
This means → On the surface the strait looks nearly empty, but grey-market shipping continues underground. The market worry is that this latest escalation will reverse the modest recovery in Gulf oil flows seen over the past few weeks.
What is Japan doing to prepare?
Japan, a resource-scarce major energy importer, is drawing up an energy import diversification plan.
The plan will include provisions to support Middle East pipeline construction, aiming to reroute export oil flows to channels outside the Strait of Hormuz.
Put simply = Japan's logic is straightforward — if the strait cannot be relied upon, help oil-producing nations build pipelines so crude can leave through a different exit, bypassing the chokepoint entirely.
