California jobbers already know how this goes when crude moves; here's what happened in the last day.
Oil at $75.40 after the ceasefire collapse
Oil jumped more than 7% Wednesday after President Trump declared the interim Iran ceasefire over and called the signed memorandum a waste of time. Brent for September traded at $79.76 a barrel by mid-morning, up 7.6%; WTI for August was at $75.40, up 7.2%. The trigger was Iran attacking three commercial vessels in the Strait of Hormuz on Tuesday and the U.S. hitting back. Anyone who priced product off Tuesday's screen got a bad surprise Wednesday. For jobbers, a $5 barrel move works out to roughly 12 cents a gallon at the rack before anything else moves, so watch your replacement cost this week.
The rare inventory build
Crude stocks rose 3.0 million barrels for the week ending July 3, per EIA. That put commercial stockpiles at 411.4 million barrels, still 6% under the five-year average for this time of year. The build ran opposite to API's number a day earlier, which showed a small 399,000-barrel draw. RBN read the weekly report as a softening in the supply-driven tightness that the Iran conflict had been driving. So the physical market was loosening right as the paper market spiked on the ceasefire headline. Those two signals point different directions, which is worth sitting with before you lock volume.
Propane draws early
U.S. propane inventories posted a counter-seasonal draw for the same week, below what the trade expected in early July. The decline centered on PADD 3, where stocks logged their largest same-week draw. Draws this time of year are unusual because this is build season ahead of winter. If Gulf Coast propane keeps drawing instead of building, retailers filling tanks this summer could see less cushion by heating season.
Record exports
U.S. petroleum exports hit 13.6 million b/d in April, a record and 15% above March's prior high. EIA tied it to Hormuz disruptions pushing global buyers toward U.S. barrels. More export pull is one reason domestic stocks stayed below the five-year average even with the surprise build.
What lube buyers should expect
Finished lubricant prices are not tracking the crude selloffs, and JobbersWorld laid out why: short-term crude swings do not reset the broader base-oil and additive cost chain fast. So if a customer asks why oil is down but their drum pricing is not, the honest answer is that the cost stack behind a finished lube moves slower than the crude screen.
What to watch
Whether the strait stays navigable, since that is doing most of the work on both price and export demand. Watch next week's WPSR for whether the crude build was a blip or the start of a real rebalancing, and watch Gulf Coast propane to see if the draw holds.
