周五，10年期美国国债收益率徘徊在4.21%附近，接近四个月低点，因为投资者正在等待美联储首选的通胀指标个人消费支出价格指数，以获得新的政策信号。预计7月份核心个人消费支出将呈现2.9%的年增长率，为五个月来最快增速。周四公布的修订数据还显示，在商业投资和贸易强劲的支撑下，美国经济在第二季度增长略快。与此同时，美联储理事克里斯托弗·沃勒周四晚间表示，他赞成下个月开始降息，并“完全预计”随后将进一步降息，以使政策更接近中性立场。随着交易员加大对美联储宽松政策的押注，8月份基准收益率下降了近20个基点，市场目前认为9月份降息25个基点的可能性为86%。

The yield on the 10-year US Treasury note hovered near 4.21% on Friday, holding close to four-month lows as investors awaited the PCE price index, the Federal Reserve’s preferred inflation gauge, for fresh policy signals. Core PCE is expected to show a 2.9% annual increase in July, the fastest pace in five months. Revised figures released Thursday also indicated the US economy grew slightly faster in Q2, supported by stronger business investment and trade. Meanwhile, Fed Governor Christopher Waller said late Thursday he favors beginning rate cuts next month and “fully expects” additional reductions to follow in order to bring policy closer to a neutral stance. The benchmark yield has dropped nearly 20 basis points in August as traders ramped up bets on Fed easing, with markets now assigning an 86% probability of a 25 basis-point cut in September.
