US-Iran Gulf Conflict Lifts Tanker Rates to Record as Saudi Arabia Reroutes Crude

Oil tanker freight rates have climbed to historic highs as rising shipping risks in and out of the Middle East push traders and tanker operators toward less efficient and more costly routes. Crude supply itself remains available, but moving it through the Strait of Hormuz remains a high-risk operation. US-Iran tanker confrontations in the Persian Gulf and the Gulf of Oman continue to escalate, while Saudi Arabia has begun moving crude cargoes out of the region via the northern Red Sea and Egyptian Mediterranean ports.

Longer diversion routes tie up tankers and very large crude carriers for extended periods, tightening the market for available vessels and driving rates to record levels. The benchmark daily rate for a very large crude carrier (VLCC) from the Middle East to China has set a record high of nearly 800,000 dollars. For a VLCC carrying crude from the US Gulf Coast to Asia, the lump-sum cost per voyage has reached 29.5 million dollars, a figure that does not include additional war-risk premiums or costs arising from unexpected delays.

In reports for the week ended September 9, 2026, shipbrokers said the list of available VLCC positions has become very tight. Crude still needs to be shipped out through the Strait of Hormuz, and Iran has stepped up efforts to block such transport. Bottlenecks are appearing across multiple segments of the shipping chain at the same time, weighing on the market, a situation already reflected in freight rate levels.
