Japan's Ministry of Finance will auction 700 billion yen of 20-year government bonds on Sept. 15.

据高测算，标普500成分股过去六个月的实现相关性已降至11，近25年仅2007年2月和2018年1月出现过相近水平。低相关性意味着个股围绕AI、盈利与行业逻辑各自波动、彼此抵消，使指数实际波动持续受到压制。一旦宏观冲击令个股重新同涨同跌，分散化效应减弱，指数波动可能以更快速度放大。Cboe也指出，相关性跃升通常伴随系统性风险与尾部波动上升；2026年3月，一月期隐含相关性就曾由约15升至40，令分散交易快速承压。
