$80 Million Voyages: Tanker Crisis Cuts U.S.-Asia Crude Flows in Half

Freight for a U.S. Gulf Coast-to-Asia supertanker voyage hit $80 million earlier this month — roughly ten times the average rate that held for years before the Iran war. That single number explains why Asian refiners have cut November orders for U.S. crude by half. The U.S. export arb to Asia is, for now, effectively closed.

How far have Asian bookings fallen?

Asian refiners have ordered about 25 million barrels of U.S. crude for November delivery, down roughly 50% from September, according to anonymous traders familiar with the purchases who spoke to Bloomberg. Rates have eased from the early-October record but still sat near $60 million per voyage this week.

If orders stay at this pace through the monthly trading cycle, vessel-tracking analysts expect Asia to receive its lowest volumes of U.S. crude in seven years. U.S. crude and petroleum exports surged to a record in the early weeks of the Middle East war. The conflict then broke the tanker market on top of the supply and fuel crises.

The takeaway: one month of record freight has undone seven years of export growth.

What broke the VLCC market?

The answer sits outside the Strait of Hormuz. Ship-to-ship transfers in the Gulf of Oman have expanded into a shuttle fleet of about 80 VLCCs, which sit idle for weeks waiting to load cargo floated out of the Strait. That tonnage is unavailable for the long-haul routes, including the U.S. Gulf to Asia.

The inefficiency is measurable. Kpler data show average round-voyage times on the Basrah-to-Sohar offshore Oman run have reached 23 days, against an optimal 9-10 days — more than double, for the same trip. Record Persian Gulf and Gulf of Oman rates are also luring owners into the riskier but far more lucrative Middle East trade, leaving other routes short of vessels.

The takeaway: the Hormuz workaround is consuming the world's spare tonnage.

What does the freight bill look like per barrel?

Randy Hawkins, Vice President, International Crude Oil Supply and Trading at Valero Energy, addressed the question directly on the refiner's earnings call this week. Freight rates, he said, are now the main story on the market.

"The cost to move a VLCC from the Gulf Coast to Asia is now averaging around 30 to $35 per barrel. That compares with the 2025 average of around $5 a barrel," Hawkins said. He added that the surge is "causing severe dislocations in our global crude pricing as refiners seek to find barrels that are closer to home and sellers are forced to discount barrels to account for the freight cost."

At $30-35 per barrel, freight alone can exceed the value many cargoes once carried.

Where is the crude going instead?

Asian buyers are switching to Middle East crude, bought on a delivered basis to shift the freight risk. European refiners are opting for nearby regional volumes. The result is a widening split between short-haul and long-haul grades.

Premiums on close-in barrels are setting records:

• Dated Brent traded at a record $20/bbl premium to Brent last week.
• Norway's medium sour Johan Sverdrup hit a record $24/bbl premium to Brent, per Wood Mackenzie data.
• Some West African grades have slumped to discounts as deep as minus $20/bbl to offset voyage costs.

The U.S. is on the wrong side of the same divide. The Midland East Houston (MEH) premium over WTI has collapsed to $0.25/bbl, from more than $3/bbl in early September, per Link Data Services estimates cited by Bloomberg. Gulf of Mexico medium-sour Mars, a substitute for many Middle East grades, has seen its premium fall to $6/bbl from $17.50/bbl at the end of March.

The takeaway: distance from Asia is now priced as a liability, not a logistics detail.

What comes next?

The watch item is the November loading program and the size of the Gulf of Oman shuttle fleet. Every extra week of 23-day round voyages keeps VLCCs captive and U.S. barrels discounted. If Hormuz transit normalizes, the 80-vessel shuttle unwinds and freight retraces toward that $5/bbl average. Until then, Midland's marginal barrel stays at home.
