U.S.-Iran Tensions Push Oil Prices Higher as Diesel Margins Hit Records

Recent declarations between Iran and the U.S. have made the prospects of peace in the Middle East even more distant, leading to a surge in crude oil prices. Brent crude is currently trading at $91.33 per barrel, while West Texas Intermediate is at $85.08 per barrel. This escalation comes after Iran announced it would adopt a "fully offensive" strategy in its conflict with the United States, following the U.S.'s refusal to extend a ceasefire that lasted less than a month since June.

A senior Iranian official warned that Iranian entities must be prepared to escalate tensions in the Strait of Hormuz and the wider region, ready to make difficult decisions and take action.

The tension between the U.S. and Iran has intensified, further complicating an already uncertain situation. The recent threat from President Trump to bomb Gulf ally Oman if it finalized a deal with Iran for joint management of the Strait of Hormuz adds to the uncertainty. Meanwhile, the crack spread for diesel in U.S. refineries has surged above $100 per barrel, indicating a severe supply crunch for the fuel due to the Middle Eastern conflict.

This crisis is global, with the International Energy Agency reporting that global refinery run rates are down to 80.9 million barrels per day, a decrease of 5 million barrels per day compared to the previous year.

The diesel production has been particularly hard hit as refineries have shifted focus to gasoline and jet fuel production earlier in the summer, driven by the peak travel season. However, the situation was exacerbated by Ukrainian drone attacks on Russian refineries, causing fuel shortages. In response to these attacks that disrupted fuel supply, Russia banned diesel exports until the end of the year.
