Developments in China triggered significant turbulence for the aluminium market in 2015. We expect 2016 to be the low point in the current down cycle for the average annual LME price a year when the global supply demand balance tips into a nominal deficit. It will also be a year when risks to our base case will be at their highest with concerns that global demand growth may decelerate more sharply than our base case view and that the announced capacity curtailments in China do not materialise or are more than offset by activation of significant new capacity. The annual average cash price fell 11% in 2015 and we anticipate another year of tepid price action. We expect the cash price to shed $92/t in 2016 versus 2015 registering 5.5% decline. This Insight assesses the main themes likely to emerge in 2016 and the main risks to our base line forecasts.
