Its relaxed attitude about inflation reflects its focus on the longer-term past, with PCE inflation at just 1.5% for the 12 months to August of this year, the same as the “core” PCE inflation rate, which excludes food and energy. But PCE inflation has also been rising, with the most recent quarterly value at 2.3% year on year in the April-June period.
美联储更喜欢用个人消费支出（PCE）物价指数衡量通胀。其对通胀的轻松态度反映了其对长期历史的关注，今年8月，12个月PCE通胀只有 1.5%，与剔除食品和能源的PCE“核心”通胀率相同。但PCE通胀一直在上升，4月—6月的最新季度值同比上涨2.3%。
