Mexico’s August trade deficit widened more than expected as imports of petroleum products far outstripped oil exports and as manufactured goods sold abroad fell from the same month a year ago, Dow Jones quoted the National Statistics Institute as saying. The nation’s trade deficit last month was $2.8 billion, wider than expectations of a $2.03 billion deficit in a survey of six economists by The Wall Street Journal. The January-August deficit was $9.12 billion, or more than double compared with the same period last year, the institute said. Overall exports fell 6.8% to $31.03 billion, while imports dropped 1.9% to $33.83 billion.
