“Dark” Tanker Fleet Shatters Iran’s Hormuz Stranglehold As Gulf Oil Exports Top Two-Thirds Of Pre-War Level

Brent crude futures initially jumped overnight after The Wall Street Journal reported that President Trump has no interest in reviving the memorandum of understanding (interim peace deal) reached with Iran in June. The war-risk premium in Brent has since faded in New York premarket trading amid mounting developments this week that major Gulf producers, including Kuwait and Qatar, are increasing tanker flows through the Strait of Hormuz. Emerging diplomatic traction between Oman and Iran has also further reduced the perceived risk of a prolonged disruption.

Reinforcing this week’s developments, new data from Daan Struyven, Goldman’s co-head of Global Commodities Research and head of oil research, show that Persian Gulf oil exports have recovered to more than two-thirds of prewar levels.

Struyven wrote in a note late Thursday that Gulf-area exports of crude and petroleum products have rebounded sharply to between 15 million and 16 million barrels per day, up from a March low of 5 million to 6 million barrels per day.

He said crude flows remain 7 million to 8 million barrels per day below prewar levels, but the recovery has been strong enough to ease fears of a prolonged disruption at the world’s most important maritime chokepoint.

Oil shipments through the Strait of Hormuz are estimated at 8 million to 10 million barrels per day. Traders surveyed by Bloomberg place that range much lower, at between 6 million and 8 million barrels per day.

“Although our estimates focus on total Gulf flows, the upward revisions suggest Strait of Hormuz oil transits are likely close to US officials’ 8-10mb/d estimates. The rise in dark crossings by specialized shippers and in ship-to-ship transfers shows that producers and shippers are adapting to the Middle East conflict,” Struyven told clients.

He noted, “Shipping markets now price in disruptions likely continuing well into 2027 (Exhibit 7). Still, potential additional dark flows and price-sensitive China net crude imports may moderate the upside to crude oil prices even if Mideast disruptions last longer. We continue to see greater price upside to European natural gas prices and deferred oil product prices in persistent disruption scenarios than for crude.”

Readers by now understand that the energy crisis is not necessarily in crude oil but, in fact, in refined products, with the U.S. diesel crack spread trading at $93 per barrel Friday morning. The spread blew out last week, reaching a record above $100.

The takeaway from Goldman’s Struyven is that, even though the critical waterway has not fully reopened, a growing fleet of dark tankers is transiting the strait and defying Iran’s blockade. That raises the question we have asked in recent weeks: Is Iran’s geopolitical leverage over the Strait of Hormuz eroding?

Overnight, Trump posted an image on Truth Social depicting the Strait of Hormuz as “New U.S. Territory.”

In late March, we cited a note from Zoltan Pozsar’s advisory firm, Ex Uno Plures, pointing out that Trump was “methodically building a portfolio of assets” to pressure China, including adding the Strait of Hormuz (read here).

The question is whether Trump will stop at Hormuz or embark on another crusade in the Gulf and take Iran’s Kharg Island. This newly minted portfolio also includes Venezuela, where the U.S. is nearing a deal to secure long-term energy-producing assets in the country.
