Trump deploys reserves as Brent crude surges past $110 amid Iran crisis

Oil markets seized up in March 2026 as geopolitical shock rippled through the global energy system. Brent crude, the international benchmark, had climbed past $110 a barrel—a surge driven not by gradual market forces but by a single, acute disruption: war in Iran had throttled the Strait of Hormuz, the narrow waterway through which nearly a fifth of the world's oil flows each day. Within weeks, American drivers felt it at the pump. Gasoline prices had jumped to $3.84 a gallon, a 31 percent climb in just thirty days and the steepest monthly rise in three decades.

The numbers told a story of cascading failure. The Iran conflict had knocked roughly 10 million barrels per day offline—about a tenth of global supply. Gulf producers like Saudi Arabia, Iraq, the UAE, and Kuwait all reported significant production cuts as infrastructure faced attack and export routes grew treacherous. Oil shipments from the region had collapsed from 25 million barrels daily to 10 million. Liquefied natural gas facilities, particularly Qatar's critical Ras Laffan and North Field complexes, faced their own disruptions, putting 20 to 25 percent of global LNG supply at risk. Natural gas prices jumped more than 6 percent to $3.26 per unit. West Texas Intermediate crude, the American benchmark, hovered near $100 a barrel. The energy shock was real, immediate, and spreading.

President Trump moved fast. His administration released 172 million barrels from the Strategic Petroleum Reserve, part of a coordinated international effort that would eventually inject 400 million barrels into global markets. The administration also took a more controversial step: it temporarily lifted certain sanctions on Russian oil, allowing shipments already in transit to reach buyers. A waiver of the Jones Act followed, permitting foreign vessels to transport oil between U.S. ports—a logistics move designed to ease domestic bottlenecks. The administration pushed American oil producers, already the world's largest, to increase output further. These were not subtle gestures. They were the moves of a government facing mounting pressure as midterm elections approached, trying to demonstrate control over a market spiraling beyond its reach.

Yet the interventions revealed their own limits. Russia, sensing opportunity in the sanctions relief, began shipping additional crude to Asian markets—roughly 600,000 barrels daily, enough to offset only 5 to 6 percent of the Gulf's lost supply. The gap remained vast. Experts were skeptical that domestic measures could fully insulate America from global price movements. When Brent crude rises, refining costs rise with it. Supply chain disruptions, shipping delays, and refining capacity constraints compounded the pressure. Consumers felt it everywhere: transportation costs climbed, agricultural expenses rose, inflation ticked upward. The pump remained a political problem Trump could not simply solve.

The future hung on forces largely outside Washington's control. If the Iran conflict escalated further, crude could climb higher still, pushing gas prices into territory not seen in a generation. If diplomatic efforts succeeded and supply routes reopened, prices might stabilize—though infrastructure damage and lingering uncertainty could keep them elevated for months. The role of OPEC nations, Russia's longer-term position despite sanctions relief, and the actions of other major producers would all shape what came next. For now, markets remained volatile, consumers remained anxious, and the narrow strait between Iran and Oman remained the most consequential chokepoint in the global economy.
