The price of physical crude oil will hit $150 a barrel this year in the United States due to unrest in North Africa and the Middle East, despite the emergency oil stock release coordinated by the International Energy Agency (IEA), a U.S. fund manager said. Monty Guild, the chief executive of Guild Investment Management, said the IEA's move did not change oil's fundamentals."Our opinion continues to be oil prices will reach $150 barrels this year due to the fighting near Saudi Arabia," Guild told Reuters in a telephone interview. -Reuters
