铜价再创历史新高，供应端收紧预期成为行情的重要支撑。 9月8日，伦敦金属交易所（LME）三个月期铜盘中触及每吨14694美元，刷新历史纪录，收盘报14673美元，日内上涨1.5%。铜价突破前高之际，矿业股同步走强，自由港麦克莫兰盘中一度上涨逾7%，年初至今涨幅扩大至约44%。 更值得关注的是，全球铜矿供应预期正在发生变化。摩根士丹利已将此前的全球矿山供应增长预期下调至基本持平甚至小幅下降，若最终兑现，全球铜矿产量或出现2017年以来首次年度下滑。与此同时，智利连续第二个季度下调全年产量预期，美国潜在关税引发的“抢货”又进一步加剧了全球库存错配。 铜价刷新历史新高，大摩下调全球供应预期 供应端的变化正在成为铜价突破历史高位的重要催化剂。 智利是全球最大的铜生产国，但近期产量表现持续承压。该国第二季度铜产量创至少19年来最弱水平，并连续第二个季度下调全年产量预期，预计全年产量将下降2.6%。在此背景下，摩根士丹利逆转此前对全球矿山供应扩张的判断，将供应预期下调至基本持平甚至小幅下降。 如果这一预测兑现，意味着全球铜矿供应将自2017年以来首次出现年度下降。英美资源集团首席运营
