For the third year in a row, the summer driving season kicked off with national gasoline prices at $3.67 per gallon, according to data from the U.S. Department of Energy. Prices at the pump are below the $3.80 – $4.00 danger zone where they contributed to economic soft spots in 2011 and 2012. But they may head higher with crude oil prices rising over $104 lastweek — well above the levels seen around Memorial Day weekend duringthe past couple of years. While the conflict in Ukraine may be fueling some f the price gain, this is nothing new — a year ago the world was focused on the conflict in Egypt, and in 2011, the civil war in Libya was the sourceof geopolitical risk to oil prices. So why — if the United States is producing more oil and consuming less than it was a decade ago — is the price of oil going up, and what does it mean for investors?
