Dual Supply Shocks Drive First US Gasoline Price Increase Since May
The collapse of a US-Iran ceasefire has halted a months-long decline in pump prices by choking off a critical Middle East shipping lane, compounding refined product shortages caused by Ukrainian strikes on Russian infrastructure.
US motorists are paying more at the pump for the first time since May as a resumption of hostilities between the United States and Iran triggers a sharp rise in crude prices. The national average for a gallon of gasoline reached $3.8590 on Tuesday, up from $3.7900 a week prior, according to AAA data. GasBuddy reports that roughly 80% of states saw retail price increases, tracking a roughly 15% weekly surge in oil markets.
The abrupt reversal at the retail level follows the breakdown of a tentative US-Iran ceasefire, which has rapidly escalated into a direct military confrontation. US forces struck Iranian radar installations, air defenses, and Revolutionary Guard positions. In response, President Donald Trump reinstated a naval blockade on Iranian shipping and demanded transit fees for vessels moving through the Strait of Hormuz. Iran retaliated by attacking US-linked military facilities across Bahrain, Kuwait, Oman, and three other nations.
For commodities investors, the primary concern is a severe contraction in commercial shipping through the Strait of Hormuz, the world's most critical energy chokepoint. Maritime intelligence indicates that vessel traffic through the corridor has plummeted by roughly 50%. This bottleneck threatens the uninterrupted flow of both crude oil and liquefied natural gas, stripping global supply chains of a crucial buffer just as markets adjust to the new geopolitical risk premium.
Compounding the Middle Eastern disruptions is a simultaneous supply shock originating from the conflict in Eastern Europe. Ukraine has expanded its drone campaign against Russian energy infrastructure, crippling major oil depots and processing terminals in Tver, Stavropol, Bataysk, and Ufa. Independent analysts estimate these sustained barrages have disabled approximately one-third of Russia's total refining capacity.
The systemic damage to Russian infrastructure forced Moscow to announce a ban on diesel exports last week in a bid to rescue its collapsing domestic fuel market. The convergence of a choked Strait of Hormuz and the sudden removal of Russian refined products from the global market points to sustained upward pressure on fuel prices. “While the pace of increases doesn’t yet appear likely to match what motorists experienced in March and April, fresh Ukrainian attacks on additional Russian refineries will only add to the pressure, keeping supplies of refined products tight even as the situation remains fluid,” said Patrick De Haan, head of petroleum analysis at GasBuddy.
