Oil prices surge above $90 as Middle East conflict escalates

Oil prices surged Sunday, with Brent crude rising above $90 per barrel for the first time since mid-June, as escalating Middle East hostilities following the deaths of three U.S. service members stoked fresh supply fears. The jump, which builds on weeks of steady gains, threatens to push U.S. gasoline above the psychologically important $4-per-gallon mark and reignite global inflation pressures.

Why oil is climbing

The latest rally comes after a weekend of intensified attacks, including reported Iranian strikes on oil and electricity infrastructure in Kuwait, and follows the collapse of a fragile U.S.-Iran ceasefire. Tanker traffic through the Strait of Hormuz—a critical chokepoint for global oil shipments—has fallen again after a brief rebound, according to shipping data. Analysts say the market is now pricing in a greater risk of sustained disruption in the region.

The nationwide average U.S. gasoline price stood just under $4 per gallon Sunday, according to AAA, and is expected to climb above that level Monday. Higher diesel prices are also squeezing freight carriers, adding to concerns about broader supply chain costs.

Iran and the US: Rhetoric escalates

Iran's Supreme Leader Mojtaba Khamenei on Saturday accused President Trump of violating the U.S.-Iran agreement and promised a strong response from Iran and its proxies if hostilities continue. Trump dismissed the comments, telling NewsNation he 'couldn't care less' about the Iranian leader's remarks regarding the agreement. The exchange signals that diplomatic channels remain largely closed, leaving military escalation as the dominant dynamic.

The weekend violence, including the three American fatalities in Jordan, has hardened positions on both sides. While the White House has not announced a shift in strategy, the mounting casualties and infrastructure attacks suggest the conflict is entering a more dangerous phase.

Market resilience under strain

Oil markets have shown surprising adaptability throughout the crisis, thanks to factors such as reduced Chinese import demand, coordinated releases from strategic stockpiles like the U.S. Strategic Petroleum Reserve, and ample commercial inventories. These buffers helped prevent even larger price spikes earlier in the conflict.

But analysts warn that those shock absorbers are eroding. The effectiveness of Ukraine's drone attacks on Russian refineries has prompted Russia to ban diesel exports, squeezing global supplies of refined products. Meanwhile, dwindling spare capacity among major producers and fading stockpile releases mean the market has fewer tools to absorb fresh disruptions.

Brent crude's move above $90 reflects this growing fragility. If the fighting continues to disrupt shipping or directly targets energy infrastructure, prices could spike further, with direct consequences for consumers and central banks already battling inflation.

What comes next

The immediate focus is on whether the U.S. and Iran can restore any semblance of the ceasefire or if the region will see a new cycle of strikes. Traders will also watch for any coordinated response from major economies, including additional releases from strategic reserves. For now, the upward pressure on oil and gasoline seems likely to persist, testing both political leaders and household budgets as the conflict shows no signs of de-escalation.
