“It has been a quiet week for the national average, with little overall movement in average gas prices nationally even as oil prices have been a bit unstable. Some states have seen minor increases while others have seen decreases, and the mixed bag is likely to continue for the time being with oil prices a bit all over the place,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “While gasoline demand continues to inch up, we could see additional pressure on pump prices, while the price of diesel continues to see downward movement. While the uncertainty over the direction of the economy is a major player in preventing oil’s rise, inventories of oil and gasoline do remain tight, preventing much additional downward movement as well. We’ll have to see which of those factors emerges as a winner to predict when the next large movement in prices could be. We’re also seeing more tropical activity in the Atlantic that could pose challenges in the weeks ahead as hurricane season ramps up.”
