高盛：大宗散货交易与研究团队铁矿石问答 20260131 摘要 中国港口铁矿石库存处于历史正常区间，但仅从供需基本面来看，当前 价格区间难以维持。高频数据显示中国铁水产量仍处于高位，印度出口 减少，共同作用下港口库存保持平稳。 全球铁矿石出货量持续增长，供应端表现强劲，但中国钢铁行业面临严 重的供过于求，生产商利润空间受到挤压，钢铁出口的高增速难以持续， 市场或需通过产量下降来重新平衡。 中国矿产资源集团（CMRG）限制钢厂采购必和必拓大块矿产品，减少 了钢厂可获取的铁矿石量，在春节前补库周期支撑了铁矿石指数，但长 期来看，可能导致必和必拓业绩受损。 多数基金在战争相关资产上配置资金，并部署风险敞口在空头端，配对 交易策略中，多黄金空铜策略热度超过多黄金或多金属空铁矿石策略， 反映了市场对铁矿石的谨慎态度。 生产商倾向于在 106-108 美元进行对冲操作，消费商则在 103-104 美 元买入，波动区间有限。大部分创始人仍通过空头配置，财务状况稳定， 但整体来看，市场参与者对铁矿石价格的预期分歧不大。 Q&A 尽管近几个月铁矿石市场基本面恶化，铁矿石价格为何仍维持在 100 美元以上？ 回顾过去六个月，铁矿 ...
