Chevron CEO Mike Wirth said the conflict between the U.S. and Iran is putting upward pressure on global oil prices.
The warning highlights the fragility of global energy supplies during geopolitical instability. Because the Strait of Hormuz is a critical transit point for oil, any prolonged crisis there threatens to sustain high costs for consumers, and industries worldwide.
Speaking during a CNBC Squawk Box interview on Friday, Wirth said the current U.S.-Iran conflict is hitting global oil markets harder than the Russia-Ukraine war [2]. He said that oil prices are likely to remain under upward pressure [1].
This volatility follows a period of instability earlier this year. Oil prices were depressed during the first two months of 2026 [4], but they spiked after the U.S. and Israel attacked Iran on Feb. 28, 2026 [4]. The subsequent crisis in the Strait of Hormuz has disrupted oil shipments, limiting available supply [4].
Wirth said that energy companies cannot simply compensate for these disruptions through immediate output increases. "We can't turn on production at a moment's notice," Wirth said [1].
Other political factors continue to influence market fluctuations. President Donald Trump previously put a 10-day clock on Iran [6]. While some reports indicate prices fell after Trump expressed intent to make a deal with Iran [6], Wirth's assessment focuses on the structural supply constraints caused by the conflict.
The CEO's comments underscore the difficulty of balancing global demand when primary shipping lanes are contested, a challenge that persists despite diplomatic efforts to stabilize the region.
“The US‑Iran conflict is hitting global oil markets harder than the Russia‑Ukraine war.”
The situation indicates that oil markets are currently more sensitive to Middle Eastern instability than to previous European conflicts. Because oil production lacks the elasticity to respond instantly to supply shocks, the volatility in the Strait of Hormuz creates a price floor that is difficult to lower without a comprehensive diplomatic resolution between the U.S. and Iran.
