  • 简介:最近,江铜子公司江铜国贸发表声明称:中国大型铜冶炼和贸易公司已达成共识,将在未来两个月内加大向伦敦金属交易所(LME)注册仓库交仓力度,出口"足够"数量的电解铜。上述铜冶炼公司包括中国铜原料联合谈判小组(CSPT)主要成员企业和祥光铜业等,期望通过此举调剂国内外市场供求。这则消息被众多媒体及市场人士解读为中国铜企被某国际现货企业(传言为嘉能可)软逼仓,也有人拿2003-2005年国储铜事件与此次逼仓相比较,认为有可能导致另一轮逼仓行情出现。如何解读江西铜业这次与公司多年来从国外"只进不出"行为背道而驰的举动?据了解,江西铜业大部分的铜料需要通过进口解决,加上国内销售旺盛和出口关税较高,理论上电解铜不存在出口的条件。特别是近几年来,由于经济高速发展以及制造业不断扩张,中国的铜尤其精炼铜资源短缺越发明显,因此中国的铜一旦"反常出口"将具有特别含义。为此,本刊特邀金瑞期货策略分析师黄宏军对此进行深度解析。黄宏军认为,身为江铜子公司的分析师,应站在中立的角度来分析此次事件,并且将通过对比2003~2005年国储铜逼仓事件与本次逼仓的不同之处来判断其成功的可能性。
