Crude posts a second straight weekly gain on Iran sanctions and Russian refinery strikes

California and Texas jobbers just watched crude book its second straight weekly gain, and the reasons are all overseas. Brent is trading at $93.50 a barrel and WTI at $86.43, both climbing on the prospect that the fighting near Russia and Iran gets worse before it gets better. For anyone buying wholesale gasoline or diesel this week, higher crude is the story, and none of the pressure is coming from US fundamentals.

Iran sanctions

Iranian crude available to Chinese buyers has nearly run out. Total Iranian volume sitting outside the Persian Gulf and Gulf of Oman is about 83 million barrels now, down from more than 100 million before the US reinstated its blockade on Iran's oil exports. China's independent refiners, the biggest buyers of that barrel, may have to find other supply as soon as next month.

That matters to a US operator because those refiners don't disappear when Iran dries up. They bid for barrels somewhere else, and that competition props up the global price that sets your rack cost. Trump added to it Wednesday with a threat of what he called the toughest sanctions in history on Iran. Prices climbed after the post.

Russian refining hit

Ukrainian drones struck Lukoil's Perm refinery deep inside Russia, more than 1,500 km from the front. Zelensky confirmed the strike, which also hit the Marinovka airfield and damaged a Su-34. The Perm plant processes about 13 million tons of crude a year, so taking capacity offline there tightens Russian product supply and keeps a bid under diesel and crude benchmarks worldwide.

These strikes have become a pattern, and each one that lands on refining capacity does more to the fuel side than a hit on crude production. Refined product is what's in short supply when a plant goes offline, and that flows through to the numbers on your invoice.

What it means downstream

Nothing here is a US supply problem yet. Domestic crude and refining are running normally, and the pressure on your cost is coming through the benchmark, not through any shortage at the terminal. Crude at these levels means wholesale gasoline and diesel cost more this week than last, and the crack spread math tilts toward refiners holding margin rather than passing relief down to jobbers.

What to watch

Watch where China's teapot refiners go for crude next month once the Iranian barrels are gone. If they pull hard on other grades, that keeps upward pressure on the benchmark. Watch whether Ukraine keeps reaching Russian refineries this far east, because each confirmed hit on processing capacity tightens product. And watch for any detail on Trump's promised Iran sanctions, since the market moved on the threat alone and could move again on the specifics.
