The past month has seen commodity prices come under strong downside pressure. The uncertainty that is hanging over these markets follows the announcement of US import tariffs and a stronger dollar. These have taken their toll on the complex as a whole, while copper has endured further weakness as exchange stocks and production continue to rise. Strong manufacturing activity in the US, Europe and China drove global demand growth of 2.1% in 2017. Industrial activity still looks broadly supportive for another few years of healthy demand expansion however risks to our outlook are emerging. The mine to trader market has been generally quiet during March. Concerns over copper concentrate supply disruptions appear to be easing, with new labour contracts now agreed in some high profile negotiations. Chinese smelters returned to the market later in the month, after a quiet start, and with fewer maintenance closures, bidding for material was reported to be in the low to mid-70s.
