“Higher oil prices are already manifesting in rapid increases in pump prices for gasoline and diesel,” said Jon Butcher, an economist at Aberdeen Investments. “They will result in higher prices for food and plane tickets, among other categories, over the next couple of months. But these will also cumulatively lower household disposable income and weigh on consumer spending.”
