MicroSectors Gold Miners 3x Leveraged ETN（GDXU）今日盘前股价大跌5.22%，引发了市场的广泛关注。
消息面上，国际油价飙升并突破100美元关口，强化了市场对通胀持续高企的担忧，导致美元指数大幅走强并站上100点关口，创下去年11月以来新高。强势美元与通胀压力削弱了市场对美联储降息的预期，据芝商所FedWatch工具显示，交易员已基本排除9月降息可能性，甚至对今年是否降息产生怀疑。这令黄金等非生息资产的吸引力下降，进而拖累黄金矿业板块。
此外，中东地缘政治局势持续紧张，霍尔木兹海峡航运受阻，虽然短期内为黄金带来避险情绪，但由此引发的油价飙升和通胀预期，反而通过强化美元和利率前景对黄金及矿业股构成了更大压力。在多重因素压制下，黄金矿业股普遍承压，作为3倍杠杆产品的GDXU也随之出现显著下跌。
