Aluminium prices started the second week of July with a spurt above US$3,300/t on the back of production woes coming from the Shanxi region in China. Previous attempts to breach the US$3,100/t barrier in June and May were short lived with prices not finding the support needed to stay above those levels. Aluminium bounced back with renewed strength in July on further power driven supply fears and new long positions entering the market. In June momentum came from production disruptions in UK (at the 145,000 tpy Holyhead smelter) and India (at the 360,000 tpy Angul smelter) and news that two smelters in the US (Glencore's 168,000 tpy Columbia Falls and Alcoa's 267,000 tpy Rockdale smelters) were curtailing their production levels on the back of prohibitive power prices. LME 3M prices tested the US$3,200/t level at the end of the month but the bulls appeared to hesitate to bridge that mark retreating towards US$3,150/t at the beginning of July.

中国山西的生产危机推动铝价在7月份第二周周初站上3，300美元/吨。5月份和6月份铝价试图突破3，100美元/吨的关口，但这仅是昙花一现，铝价并没有找到站上这个价位的支撑。7月份铝价反弹，电力危机引发供应担忧以及新的多头进场推动铝价走强。6月份，英国（年产能145，000吨/年的Holyhead冶炼厂），印度（年产能360，000吨的Angul冶炼厂）以及美国两座冶炼厂（Glencore公司旗下年产能168，000吨的Columbia Falls冶炼厂和Alcoa公司旗下年产能267，000吨的Rockdale冶炼厂）因电价上涨宣布减产，从而为铝价走势提供了动能。6月末，LME三个月期铝价格上探3，200美元/吨这一价位，但市场做多动力不足，铝价在7月初回调至3，150美元/吨。
