Iran claims seven ships hit in Persian Gulf as crude climbs and Iranian floating storage empties
Oil prices moved up after Iran's Islamic Revolutionary Guard Corps Navy claimed its forces hit or mined seven vessels in the Persian Gulf over the past day, including oil tankers. For jobbers, that shows up fast at the rack. Crude is the biggest line in your cost stack, and when the Strait of Hormuz looks shaky, the paper market prices in the risk before a single barrel actually goes missing.
The Gulf claim
The IRGC Navy said it tracked and hit four tankers running oil transfers in the northern Persian Gulf. Three other vessels struck mines west of the Strait of Hormuz, per the same claim.
Take the count with caution. It comes straight from the IRGC, not an independent source, and the mine claims and the "we hit them" claims are doing different work. Either way, the market read it as a reason to bid crude higher, and that premium rolls downstream into branded and unbranded rack numbers the same morning.
What matters for your shop is whether the strait stays open. Roughly a fifth of seaborne crude moves through Hormuz. Any real closure, or enough incidents that owners pull tankers and insurers jack war-risk premiums, could tighten waterborne supply and firm up Gulf Coast and West Coast numbers. Crude could ease back if the strait stays open and the incidents stop.
Iranian barrels drained
The other half of this is supply that already left the board. Iranian oil in floating storage has been drained under the US Navy blockade of Iranian ports, the Wall Street Journal reported, citing Kpler.
Before the blockade went up in April, Iran held close to 150 million barrels in floating storage. "There's no more oil to discharge to China anymore," Kpler's Homayoun Falakshahi told the paper. That stored crude had been a cushion keeping Chinese refiners fed and, indirectly, keeping other barrels free for the rest of the market.
With that cushion gone, the global balance is tighter than it was in the spring, and it's tighter heading into the Gulf scare rather than loose. Thin slack plus a fresh risk headline is how you get a jumpy rack. For marketers working allocation, that combination is the one to respect. If suppliers start trimming lifts, unbranded buyers tend to feel it first.
What to watch
Watch whether more tanker-incident reports surface from sources other than the IRGC, and whether war-risk insurance rates on Gulf cargoes move. Watch your rack spreads against prompt crude over the next few sessions. And watch supplier allocation notices. If branded suppliers go to allocation, lock your supply before the spot guys do.
