9月10日，力拓盘中下跌3.9%，报99.22美元/股，成交额3370.61万美元。
消息面上，据路透社报道，白宫尚未就精炼铜进口关税作出最终决定，官员正权衡铜价上涨推高制造成本与鼓励国内采矿之间的利弊，叠加11月中期选举前可负担性压力，关税计划陷入停滞。受此冲击，LME三个月铜期货跌2.92%至14380美元/吨，COMEX铜期货跌4.30%。此前铜价因关税预期连续刷新历史新高，贸易商大举向美国囤铜，超百万吨铜流入美国，而关税悬而未决的消息令市场急剧反转。
力拓上半年铜业务EBITDA达57亿美元、同比增长84%，铜价回落对其盈利前景构成直接压力。同业中必和必拓跌6.04%、泰克资源跌8.28%、HudBay Minerals跌8.99%，矿业板块集体承压。
