Will the United States and Iran reach a formal nuclear agreement by the end of Q4 2026?
What moved
Mitsui OSK's head flagged Hormuz transit risk persisting through year-end; tanker owners are repricing insurance and escort costs into longer-duration premium.
The market transmission
Recent attacks have lifted the perceived duration of Hormuz disruption risk beyond what operators had expected. This does not say that transits have stopped or that capacity is offline; it says that the owners moving barrels through the strait face higher insurance, escort and reputational costs for longer than they had assumed three months ago. That cost is passed into the tanker hire market and, at the margin, into crude pricing when shippers must bid harder for tonnage. The mechanism is not supply removal but supply friction: the same barrel takes more time and money to move. Spare refining capacity and weak demand growth in the Atlantic basin mean tanker rates have room to absorb the friction without crude gapping higher, but the channel is real.
What would change this
This is an expectation revision, not a new disruption. Hormuz has not closed; transits continue. The head is saying the risk duration has lengthened, which affects charter costs and insurance but not near-term barrel flow. When spare capacity is high and demand is soft, tanker-market friction does not always feed back into crude pricing the way it would in a tighter system.
