Crude jumps 6% after Hormuz tanker attacks as four ships turn back

Crude is up 6% after Iranian attacks on three commercial ships in the Strait of Hormuz on Tuesday, and that move will push up your rack invoice this week. The hit list included an oil tanker and an LNG carrier. Vessel-tracking data compiled by Reuters showed at least four oil and LNG tankers making U-turns from the strait in the past 12 hours rather than run the gauntlet.

For jobbers, the mechanism is simple. Rack pricing tracks the front-month crude and product screen with a lag of hours, not days, so a 6% pop at the barrel level shows up as higher wholesale numbers before the week is out. If you buy branded, your supplier passes the crude move through on the daily rack anyway. If you buy unbranded and shop terminals, watch for the spread between suppliers to widen as the ones with length hold firm and the short ones chase.

Allocation risk

There's no allocation today. The thing to watch is whether tankers keep turning back. About a fifth of the world's seaborne oil moves through Hormuz, and even a few days of disrupted flow can pull barrels out of the water that were headed for the Gulf Coast and Europe. That tightens the physical market that feeds your terminal, and tight physical markets are where allocation notices start.

Keep your tanks fuller than usual this week. If your supplier's terminal runs dry or goes to allocation, being caught at a quarter-full is how you end up buying spot at a premium.

Europe and LNG

European gas prices jumped on the same Hormuz news, on worry that LNG cargoes get held up. That matters to a US operator because it keeps a bid under US LNG exports, which supports domestic natural gas and, downstream, anything priced off it. Not a direct diesel input, but it colors the whole energy complex you're buying into.

Biodiesel feedstock

Malaysian palm oil futures rose 0.66% to 4,577 ringgit a ton, about $1,123, on El Niño supply fears and biodiesel demand. Palm is not a US blendstock, but it sets the floor for the global vegetable-oil complex that soybean oil trades against, and soybean oil is your biodiesel and renewable-diesel feedstock. Firmer palm could keep biodiesel and RD costs elevated into blending season. S&P Global's Platts Chicago and T2 ethanol tracker is the one to bookmark if you blend E10 and want to see where the corn-side cost is heading.

What to watch

Whether more tankers turn back from Hormuz, or the flow steadies. If ships keep transiting, crude could ease and the rack spike fades fast. If the attacks continue and cargoes pile up outside the strait, watch your suppliers' terminal notices for the first sign of allocation.
