美国9月交通消费价格同比上涨7.9% 汽油对整体通胀贡献达29.5%
美国交通部交通统计局（BTS）10月14日发布的交通消费者价格指数（Transportation CPI）多式联运专题报告显示，2026年9月美国交通消费品和服务价格同比上涨7.9%，对当月整体消费价格3.7%的同比涨幅贡献了35.4%，在八大消费类别中贡献居首。BTS表示，这是该机构合成指数的最新一次测算。这份报告是劳工统计局同日发布的9月整体消费者价格指数（本站已发布，CPI同比上涨3.7%）中交通部分的专门拆解。
分项看，汽油价格是最大推手：9月汽油价格同比上涨34.2%，单独贡献了整体通胀涨幅的29.5%。其余交通分项中，同比涨幅较大的依次为航空票价（上涨5.4%）和机动车维修与保养（上涨1.6%）；同期下降的分项有汽车保险费（下降3.7%）、二手车和二手卡车（下降0.9%）和"其他城际交通"（下降0.1%）。
BTS的这份交通消费价格专题以劳工统计局的消费者价格指数为基础，单独追踪交通相关价格对美国居民生活成本和整体通胀的影响。另据劳工统计局同日数据，9月消费者价格指数环比上涨0.7%，经季节性调整后的同比涨幅为3.7%，高于8月的3.3%。
Transportation Prices Rose 7.9% in September as Gasoline Drove Inflation, BTS Reports
The U.S. Department of Transportation's Bureau of Transportation Statistics (BTS) reported on October 14, in its latest Multimodal Consumer Price Index (CPI) release focused on transportation, that prices for transportation goods and services rose 7.9% from September 2025 to September 2026 — the highest increase among the eight spending categories — and accounted for 35.4% of the 3.7% year-over-year increase in prices for all goods and services. According to BTS, this is its latest estimate of the synthetic index. The report breaks down the transportation component of the overall Consumer Price Index that the Bureau of Labor Statistics (BLS) released the same day, which rose 3.7% from a year earlier.
By component, gasoline prices were the biggest single driver: gasoline rose 34.2% over the year and alone accounted for 29.5% of the increase in overall prices. Building on that, the largest transportation price increases after gasoline were in airline fares, up 5.4%, followed by motor vehicle maintenance and repair, up 1.6%. Over the same period, transportation prices fell for motor vehicle insurance, down 3.7%, for used cars and trucks, down 0.9%, and for other intercity transportation, down 0.1%.
BTS's transportation-focused index is built on the BLS Consumer Price Index and tracks how transportation prices affect Americans' cost of living and overall inflation. Separately, the BLS reported the same day that its Consumer Price Index rose 0.7% in September on a seasonally adjusted basis and was up 3.7% from a year earlier, compared with a 3.3% annual increase in August.
