The futures traded slightly higher Wednesday morning, and while trade remains an issue, the big story for investors is oil jumping over the $70 a barrel level for the first time since late May. The price shot up Tuesday, buoyed by uncertainty over Libyan crude exports and doubts over OPEC’s ability to boost production quickly enough to prevent a shortfall in global supplies. In addition, reports that the United States wants to cut Iran oil imports to zero also contributed to oil’s price gains.
