What Is Driving Gasoline Prices Rise This Week

AAA data show the national average for a gallon of gasoline reached 3.8590 dollars on Tuesday, up from 3.7900 dollars a week earlier. GasBuddy reports that nearly 80 percent of states saw retail prices tick upward, tracking a broader rally in crude that has pushed oil roughly 15 percent higher than a week ago. Patrick De Haan, head of petroleum analysis at GasBuddy, noted that the current pace of increases has not yet matched the jump drivers saw in March and April, though fresh attacks on Russian refineries threaten to keep refined product supplies tight.

Iran Ceasefire Collapse Reopens a Major Supply Risk

The breakdown of the tentative ceasefire between Washington and Tehran has revived one of the biggest threats to global oil flows. American forces have struck Iranian radar installations, air defense systems and Revolutionary Guard sites, while President Trump reinstated a naval blockade on Iranian vessels and is now demanding transit fees for ships passing through the Strait of Hormuz. Iran has retaliated with strikes on U.S. linked military facilities in Bahrain, Kuwait, Oman and three other countries. Maritime intelligence suggests shipping traffic through the Strait has dropped by about half, a serious concern given how much of the world's crude oil and liquefied natural gas passes through that corridor.

Russian Refinery Strikes Add to the Squeeze

The pressure on fuel supplies is not confined to the Middle East. Ukraine has kept up a sustained campaign against Russian energy infrastructure, hitting refineries, fuel depots and oil terminals. Russia responded last week by banning diesel exports in an effort to steady its own fuel market after a wave of Ukrainian drone strikes on refining sites. Ukrainian forces have managed to slip past Russian air defenses to hit facilities in Tver, Stavropol, Bataysk and Ufa. Independent energy analysts estimate these strikes have knocked out roughly one third of Russia's total refining capacity, tightening global supplies of diesel and other refined products just as Middle East tensions add their own strain.

How Crude Oil Trading Reflects the Turmoil

The United States Oil Fund (AMEX:USO) traded at 126.6 dollars, up 1.26 percent on the day, sitting within a 52 week range of 102.42 to 142.33 dollars and carrying a relative strength index of 53.8. That reading points to a market that has moved higher without yet becoming overheated, consistent with a steady but not runaway climb in crude prices tied to the twin disruptions in the Strait of Hormuz and Russia's refining network.
