Brent crude moved above $116 a barrel on March 30, marking its highest level since the war began and underscoring how quickly the conflict with Iran has become an energy-market shock as well as a military one. West Texas Intermediate also climbed, while U.S. gasoline averaged $3.99 a gallon, the highest since 2022.
The price jump came as the United States sent 3,500 additional troops to the Middle East over the weekend, one month after launching the war with Iran, according to the report. The move signaled that Washington was preparing for a conflict that is no longer confined to military exchanges alone. Traders responded to the widening risk with a bid for crude, pushing prices more than 50% higher in March.
The excerpt points to several pressure points in the supply chain. Iran’s control of the Strait of Hormuz has already disrupted oil trade, and the report says the passage of vessels through the strait has effectively been shut down since U.S. and Israeli strikes on Iran on Feb. 28. Iran’s parliament speaker warned against a ground invasion, while Trump said peace talks were still under way and floated the possibility of taking Kharg Island, through which about 90% of Iran’s crude is transported.
The disruption is no longer limited to oil tankers. The Houthis joined the fighting over the weekend by launching ballistic missiles at Israel, raising concern about the Bab al-Mandab Strait, another key shipping route linked to the Red Sea. That adds a second maritime chokepoint to a conflict that is already forcing traders, refiners and consumers to recalibrate assumptions about supply.
Iran also said it would allow 20 oil tankers through the Strait of Hormuz this week, after allowing 10 the previous week, though the report notes Tehran had not confirmed that claim. Even if the move proves temporary, it shows how fragile the market has become. With prices already at multiweek highs and gasoline reflecting the strain, the war is now shaping the daily cost of fuel far beyond the battlefield. The broader implication is that energy markets are treating the war as a supply-and-transit crisis, not just a headline event. The excerpt links that to both shipping chokepoints and political signaling, which helps explain why price moves are so abrupt: traders are reacting to the risk of a wider interruption rather than to a single outage.
The report also shows how quickly consumer prices can reflect geopolitical stress. When crude moves above a psychological threshold and gasoline follows, households feel the conflict directly. That is why the oil story is not only about barrels and benchmarks; it is about how a regional war is transmitted into everyday costs.
