On February 28, 2026, U.S. and Israeli forces initiated attacks against Iranian nuclear and military infrastructure, triggering a conflict with far-reaching economic consequences. Although this fighting has mainly played out in the region around the Strait of Hormuz, its effects have had larger effects on the entire global economy. Brent crude oil prices, for instance, have risen by about seventy-five percent since the onset of this conflict. What explains this dramatic increase, and how will the conflict continue to impact the global economy in coming months?
After Iranian Supreme Leader Ali Hosseini Khamenei was killed during this stretch of attacks on Iran, Tehran responded by closing the Strait of Hormuz, perhaps the most economically vital waterway in the Eastern Hemisphere. At its peak, roughly 20 million barrels of crude passed through the strait each day, and a black of this magnitude reaps negative repercussions on the global economy: supply delays, increased shipping costs, and surging world energy prices. As waterway traffic plummeted by over eighty percent, Brent oil prices pushed past 110 dollars per barrel.
After months of fighting, the United States and Iran finally agreed to terms on a temporary ceasefire and reopening of the Strait of Hormuz on April 7. However, talks between the US and Iran in Islamabad failed just a week after, pushing President Trump to organize a blockade of Iranian ports or ships. On April 21, President Trump declared an indefinite ceasefire but didn’t make any changes regarding US occupancy in Iranian ports. Over the course of the next several months, small-scale attacks still occurred between the two sides, but oil prices steadily began to drop: compared to about $120 per barrel of Brent crude oil at its maximum price since the start of the conflict, prices dipped to around $74 dollars by July 8.
What may have appeared as a progression towards the end of the US-Iran conflict completely reversed routes when President Trump announced the end of the ceasefire originally agreed upon in April, reviving US attacks on Iran. Since then, fighting hasn’t officially ended in spite of the temporary periods of reduced conflict from both sides, with Brent crude oil prices jumping out to over $100 per barrel again.
Consumers have felt the global repercussions of rising oil prices across the board. In the United States, increased gasoline prices have raised demand for conventional hybrids and EVs. Across the Atlantic, European Union nations continue to struggle, as roughly one-fifths of their diesel imports pass through the Strait. Moving down south, African countries were hit hard due to their heavy dependence on petrol and diesel generators in order to survive. As oil and fuel prices rose, the cost to maintain generators increased, forcing many Africans to live under unstable power supply situations. With the end of this conflict still in question, who knows what’s in store for the United States, Iran, and the rest of the world in the coming months?
