Crude oil prices have spiked more than 28 percent since the United States launched military operations against Iran in late February, triggering the most severe energy market disruption since the 2022 Russian invasion of Ukraine. Brent crude breached $102 per barrel this week, a level not seen in over two years, as traders priced in prolonged supply risks across the Persian Gulf.

The conflict, which escalated rapidly after what the White House described as credible intelligence of an imminent Iranian nuclear weapons program, has effectively shut down tanker traffic through the Strait of Hormuz—the narrow waterway through which roughly 20 percent of the world’s oil supply transits daily.

Economic Fallout Spreads Globally

The energy shock is reverberating through consumer prices and corporate earnings forecasts. Goldman Sachs revised its 2026 GDP growth estimate for the United States down to 1.1 percent from 1.8 percent, citing the compounding effects of elevated energy costs on an economy already strained by tariff-driven inflation.

European allies have expressed concern about both the military campaign and its economic consequences. Germany’s economy minister warned that sustained oil prices above $100 could push the eurozone into recession by the third quarter. Japan, which imports nearly all its crude, has begun drawing down strategic petroleum reserves.

Domestic Political Calculus

The timing presents a complicated political picture for the administration heading into the 2026 midterm elections. While initial polling showed a rally-around-the-flag effect, support has eroded as gas prices at the pump crossed the psychologically significant $5 per gallon threshold in several major metropolitan areas.

Congressional leaders from both parties have demanded briefings on the conflict’s projected duration and cost. The Pentagon has requested a supplemental appropriation of $38 billion, though defense analysts suggest the actual cost could run significantly higher if operations extend through the summer.
