9月28日，白银ETF-iShares盘中下跌5.1%，报55.175美元/股，成交额4.82亿美元。
消息面上，现货白银当日跳水逾3.6%，跌至61.9美元/盎司附近，现货黄金同步跌破4200美元/盎司。核心驱动在于：美联储持续释放鹰派信号，10年期美债收益率维持在5%以上高位，美元指数突破101，零息贵金属持有成本大幅攀升，全球交易台触发大规模平仓。与此同时，芝加哥商品交易所上调白银期货合约保证金比例，迫使资金紧张的杠杆多头被动清仓，进一步放大跌势。白银矿业板块同步承压，Global X白银矿业ETF下跌4.7%。
该ETF追踪标的为现货白银价格（伦敦银），波动方向与现货白银价格波动方向相同，一倍做多。
