“[Organization of the Petroleum Exporting Countries] surprised oil markets last week by extending oil production cuts for another month, ignoring the resurgence in global demand as economies recover from COVID-19. Markets responded by pushing oil prices up some 12%,” said Patrick De Haan, head of petroleum analysis for GasBuddy. “As a result, motorists should prepare for further gas price increases in the weeks and potentially months ahead, with a $3 per gallon national average potentially less than a month away,”
