【基本面信息】
　　铜：产业层面，昨日LME库存减少175至64100吨，注销仓单比例提高至37.9%，Cash/3M贴水10美元/吨。国内方面，昨日上海地区现货贴水缩窄至50元/吨，持货商挺价意愿较强，买盘积极性环比减弱。进出口方面，昨日国内现货铜进口亏损扩至750元/吨左右，洋山铜溢价持平。
　　铝：SMM现货A00铝报均价18330元/吨。A00铝锭升贴水平均价-110。铝期货仓单202515吨，较前一日下降973吨。LME铝库存554900吨，减少4475吨。2023年2月27日，SMM统计国内电解铝锭社会库存126.8万吨。
　　黄金：截至2月28日（周二），全球最大黄金上市交易基金（ETF）SPDRGold Trust黄金持仓量为29427686.3盎司或915.3吨，较前一交易日减少74383.01盎司或2.31吨，幅度为0.25%。
　　铁矿石：港口现货成交情况一般，现货价格持稳，钢厂按需采购。近期海外发运和到港量处于相对偏低水平，未来几周有到港量有望回升，目前港口库存仍在持续累库，港口现货资源充足。近几周钢厂利润虽有所回升，但也只是部分钢厂处于盈亏平衡线，其余钢厂仍处于亏损状态，所以钢厂铁矿石库存一直处于低位，补库意愿较低。
