U.S. producer prices rose 5.4% year-over-year in August, versus the 5.3% rate economists expected and accelerating from July's 4.8% reading, according to Labor Department data released Thursday.
On a monthly basis, the headline producer price index (PPI) accelerated from July's 0.1% to 0.4%, against a 0.3% consensus.
Core PPI, which strips out food and energy, rose 0.2% on the month against 0.3% expected, lifting the annual rate to 4.6% from 4.3%.
PPI excluding food, energy and trade services came in at 0.3% month-over-month and 4.7% year-over-year, from 0.4% and 4.7% previously.
Prior to the PPI report, Fed futures had priced a 62% chance of a rate hike at the Fed's next week meeting.
Diesel Prices Skyrocketed
Final demand goods prices advanced 1.1% in August after two consecutive declines, and more than three-quarters of that broad-based rise traced to final demand energy, which jumped 4.2%.
Over a third of the entire goods increase came from a single line item: diesel fuel, up 24.1% on the month.
Final demand services edged up just 0.1%, and the composition matters. Transportation and warehousing prices rose 2.3%, itself a fuel-cost story, with truck freight up 2.0%, while trade services margins fell 0.2%.
The cleanest read on underlying services inflation - final demand services less trade, transportation and warehousing - was unchanged in August. Portfolio management prices, which feed directly into the Fed's preferred PCE gauge, moved lower.
