“The national average price of gasoline spent much of last week drifting lower after jumping early in the week as oil prices softened on hopes that diplomatic progress between the U.S. and Iran could help ease supply concerns. However, that optimism faded after President Trump’s meeting with China’s Xi Jinping failed to produce a breakthrough on Iran, while renewed warnings toward Tehran have helped push oil prices higher again,” said Patrick De Haan, head of petroleum analysis at GasBuddy.
“With global oil inventories continuing to trend toward historically tight levels, markets remain extremely sensitive to geopolitical developments and potential supply disruptions. As a result, gasoline and diesel prices are likely to remain volatile, and with Memorial Day approaching, any sustained increase in oil prices could begin pushing retail fuel prices higher again in the weeks ahead,” De Haan added.
