US Import Prices (Sep YY) 8.1% (Prev. 6.7%)

Import price data sit in the second tier of US inflation releases, and year-on-year readings in this series are heavily conditioned by the base effects in energy and by the dollar's trade-weighted path, since imported goods are invoiced and then translated. An acceleration of this size is, on past form, more often a fuel and currency story than evidence of broad pipeline pressure, so the composition, the split between fuel and non-fuel, matters more than the headline; non-fuel import prices have historically been the cleaner read on pass-through into core goods. The transmission channel into policy runs through the goods component of the consumption deflator rather than through CPI directly, and single prints in this series have rarely moved the rate path on their own, tending instead to matter when they corroborate or contradict the trend in producer prices and the surveys' price-paid components. The follow-ons worth noting are the month-on-month rate, any revisions to the prior month, and whether the move survives once petroleum is stripped out. Absent an expectation line in the headline, there is no beat or miss to anchor on, so the read is directional only.
