Iran Hits Tankers Outside Hormuz. Diesel Costs More Anyway.
The strait's open, tankers are routing around it, and fuel prices keep climbing—because the ship shortage now starts at the shipyard.
Iran's Revolutionary Guard hit a tanker off Qatar this week, marking the first confirmed strike outside the Strait of Hormuz proper since the current phase of attacks began. The IRGC says it will target vessels anywhere in the Gulf. Markets heard the threat, shrugged, and kept pricing diesel like the 1970s are back.
Brent's up but not exploding. The strait itself is technically open—transit volumes this week matched pre-escalation averages, per tanker tracking data. Yet pump prices in the US hit multi-year highs for diesel, and Europe's paying record premiums for distillate imports. The disconnect isn't about barrels stuck in the Gulf. It's about the ships that move them.
Global tanker availability is now at the tightest level since 2008. Attacks have pulled dozens of vessels offline for repairs, security delays, or insurance reroutes. Longer voyages around Africa eat up capacity. Sanctions on Russia's shadow fleet—over 20 more vessels flagged this week by Ukraine's defense intelligence—have removed tonnage from the market just as everyone needs more of it. The result: even if crude flows, refined products can't move fast enough.
Which brings us to Trump's diesel deal with Putin. The White House announced Friday that Russia will supply the US with diesel shipments to ease domestic shortages ahead of midterms. The move explicitly relaxes sanctions pressure on Moscow, drawing immediate accusations that it contradicts standing law. The EU, meanwhile, just paid €7.9 billion for Russian Arctic LNG, so everyone's buying and no one's pretending it's about principle anymore.
The math is ugly. You need ships to move oil. You need more ships to move it farther when the short route's a shooting gallery. And you need refineries running to turn crude into diesel, which half of Europe's capacity isn't after two years of margin compression and capacity shutdowns. Iran can keep the strait open and still jack prices by forcing every cargo to add two weeks and 6,000 nautical miles.
Tanker day rates for long-range product carriers are up 47% month-over-month. New orders won't deliver until 2028 at the earliest, and shipyards in South Korea are fully booked. You can dodge the missiles. You can't dodge the fact that nobody ordered enough hulls in 2023.
So gas prices stay high even as Hormuz stays navigable, because the problem isn't the chokepoint—it's the supply chain wrapped around it. Iran knows this. Russia knows this. And every diesel buyer in the Northern Hemisphere is learning it at the pump.
