Brent moved back above $90 early Monday after the ninth consecutive night of U.S. strikes against Iran, while WTI approached $85. Both benchmarks gained more than 15 percent last week, and only four vessels crossed the Strait of Hormuz on Sunday, down from eight on Saturday.
The obvious read is that renewed military escalation has put the geopolitical premium back into crude. That’s true, but the more durable pressure may now sit farther downstream.
Crude can fall quickly when diplomatic expectations change or tanker traffic improves. Refinery outages, low product inventories and disrupted export networks don’t repair as quickly.
Brent also remains well below the $118 level it reached in April, and the Strait isn’t completely closed. Some vessels are still moving through, because the U.S. blockade applies to traffic entering or leaving Iranian ports rather than all shipping serving the Gulf. And while that leaves room for crude to come back down in price, itt doesn’t necessarily mean the pressure on finished fuel comes down with it.
The IEA estimates that observed global oil stocks have fallen by an average of 3.8 million barrels per day since the conflict began, including a preliminary 143 million-barrel draw in May. U.S. commercial crude inventories ended the second quarter at their lowest seasonal level since 2014, while refinery disruptions tied to the Iran and Ukraine wars have removed millions of barrels per day of processing capacity.
U.S. refiners are already working hard to fill the gap. They processed more crude during the second quarter than in any comparable period since 2019, and exports of distillate and jet fuel reached second-quarter records as overseas buyers searched for replacements for disrupted Gulf supply.
But strong refinery runs haven’t normalized the product market. Gasoline refining margins averaged 60 percent above their year-earlier level during the quarter, while distillate and jet-fuel margins more than doubled.
That’s the pressure point.
Households, airlines, trucking companies, farmers and manufacturers don’t consume crude oil. They consume gasoline, diesel and jet fuel, and those products are becoming more expensive while inventories remain thin and overseas demand is pulling on U.S. supply.
The system is still adapting. Record exports show that missing Gulf barrels can be replaced at least in part, and higher prices are already weakening some demand. The IEA says petrochemical consumption has softened and total oil demand has declined as the disruption has spread across regions and products.
There’s also no clear evidence yet of a broad wage-price cycle. The ECB’s survey of euro-area businesses found that expected energy costs and selling prices had risen, but wage expectations remained broadly stable.
Financial markets are showing more concern without signaling a wider break. Futures implied roughly a 65 percent probability of a September Federal Reserve increase, the 30-year Treasury yield moved above 5 percent, and India’s rupee weakened under the pressure of higher oil costs. U.S. equity futures remained broadly stable, however, and credit markets weren’t confirming a broader financial crisis.
The next signal will come from the physical market.
If Hormuz traffic remains thin, gasoline and distillate inventories fall again, and refining margins stay elevated, the pressure will move more clearly into transportation and operating costs even if Brent never returns to its April high.
If tanker traffic improves, product inventories stabilize and margins begin to normalize, the system will have bought itself more room.
The risk isn’t that the world has run out of fuel. It’s that several of the buffers that normally keep a crude disruption from reaching businesses and households have already been drawn down, and the next interruption may be harder to absorb.
