The peak U.S. summer driving season is beginning amid concerns of a gasoline supply shortage. Strong domestic demand for fuel, coupled with increased exports, is depleting already low inventory levels. This combination is expected to put upward pressure on prices at the pump for travelers. Analysts warn that limited supply could exacerbate price increases throughout the summer months. The situation is being closely monitored as vacation travel increases nationwide. The Energy Information Administration will be releasing further data on gasoline stocks and demand in the coming weeks.
