Futures dropped as much as 2.1 percent as German Chancellor Angela Merkel signaled policy makers may review Greece’s second bailout after inspectors rule on whether the country is meeting the terms of its current package. U.S. crude oil supplies climbed 1.92 million barrels to 341 million last week, the Energy Department said today.
