Middle East tensions boost oil prices
A variety of factors have lifted commodity prices this past week. Renewed Middle East fears following events in Yemen boosted oil and gold. Copper prices continued their gradual recovery, helped by supply disruption in Chile and signs of a seasonal pick-up in demand in China, while silver had another good week too. Commodity prices generally were supported by the softer dollar. But ample supply continues to weigh on key agriculturals, notably US wheat.
