Chevron CEO Mike Wirth said Sunday that upward pressure on oil prices amid the U.S. conflict with Iran is likely to continue as the war stretches into its second full month. In an interview with CBS News's Margaret Brennan on Face the Nation, Wirth warned of significant supply disruptions affecting global markets.
The Strait of Hormuz, a critical waterway for global oil shipments, has seen restricted traffic since the conflict began in late February. The U.S. instituted a naval blockade blocking Iranian ports earlier this month, further constraining oil flow through the passage that typically handles roughly one-fifth of the world's oil supply.
Meanwhile, the Treasury Department announced new sanctions Friday targeting a Chinese oil refinery and multiple shipping firms and vessels as part of efforts to disrupt Iranian oil exports. The measures aim to cut off revenue streams funding Iran's military operations.
What the Right Is Saying
Republican lawmakers have praised both the military blockade and economic sanctions as effective tools in confronting Iran. Senator Tom Cotton of Arkansas called the dual-track approach strategically sound, saying it degrades Tehran's ability to fund proxy attacks while avoiding a broader ground war.
Conservative commentators have framed the oil price pressures as an acceptable cost of confronting Iranian aggression. The Wall Street Journal editorial board wrote that markets adjusting to reduced Iranian oil flows is a feature, not a bug, of the administration's pressure campaign against Tehran.
Business-aligned Republicans have expressed concern about consumer pain at the pump but stopped short of criticizing the overall strategy. House Energy and Commerce Committee Chairman Brett Guthrie said Congress should monitor fuel prices closely while supporting allies executing a coherent Iran policy.
What the Left Is Saying
Democratic lawmakers have largely supported the administration's economic pressure campaign against Iran. Treasury Secretary Scott Bessent described the sanctions strategy as imposing a financial stranglehold on Tehran, stating that Economic Fury is designed to hamper Iranian aggression in the Middle East and curtail its nuclear ambitions.
Progressive voices have also backed the approach of economic coercion over direct military escalation. Senator Chris Murphy of Connecticut said in a statement that targeted sanctions represent a smarter path than boots on the ground, noting they impose costs on Iran's leadership without American casualties.
Environmental advocates have seized on rising fuel prices to renew calls for accelerated investment in renewable energy. The Sierra Club released a statement arguing that oil price volatility driven by Middle East conflicts underscores the urgency of transitioning away from fossil fuels.
What the Numbers Show
Global oil prices have surged since the conflict began in late February, with Brent crude rising more than 15 percent in the opening weeks of the war. U.S. retail gasoline prices have climbed accordingly, adding costs to American consumers already facing elevated inflation.
According to Wirth, jet fuel markets face particular strain because Middle East refineries supply approximately 75 percent of Europe's imported jet fuel, and those flows have been disrupted by the conflict. He told CBS News that inventories were already seasonally low before fighting began, compounding the supply shock.
The Treasury sanctions target what officials describe as a central revenue source for Iran's military. The measures specifically aim to disrupt the shadowy shipping networks Tehran uses to sell oil despite existing restrictions, including vessels and firms linked to Chinese purchases of Iranian crude.
Energy Information Administration data shows U.S. strategic petroleum reserve holdings at approximately 370 million barrels, providing a buffer against short-term supply disruptions, though administration officials have not indicated plans to tap reserves.
The Bottom Line
The conflict with Iran has introduced sustained uncertainty into global energy markets that analysts expect to persist for the duration of hostilities. With the Strait of Hormuz effectively constrained by U.S. naval operations and sanctions targeting Iranian export infrastructure, oil traders are pricing in a prolonged period of tighter supply.
For American consumers, the implications include higher gasoline and jet fuel costs in the weeks ahead, according to Wirth's projections. The Chevron CEO specifically warned that aviation fuel prices will probably worsen over the next several weeks as Middle East refinery disruptions propagate through global markets.
What happens next depends largely on conflict trajectory and whether sanctions achieve their stated goal of constraining Iranian funding for military operations without triggering broader escalation.
