Gasoline prices in US could climb to $4.50 a gallon by summer, Jan Stuart, a global oil economist for Macquarie, told CNBC Tuesday, driven by demand around the world.
“It’s a global story,” said Stuart about oil and gasoline prices. “On the middle-distance front, we find that it’s tight already. On the NAFTA gasoline LPG front, we find it’s tightening up much faster than people thought.”
