The Consumer Price Index advanced 0.4% in August after a 0.1% increase in July (unrevised) and a 0.4% decline in June (unrevised), according to the Bureau of Labor Statistics. The August rise matched the forecast in the Action Economics Forecast Survey. The y/y rate held steady at an elevated 3.4% in August (2.9% in August 2025). The CPI excluding food & energy rose a slightly more-than-expected 0.3% in August after a 0.2% rise in July and no change in June. A 0.2% increase had been expected. The y/y rate eased to 2.4%, the lowest since March 2021, from July’s 2.5%. The three-month rate for the headline CPI eased to 0.2% annualized in August from 0.5% in July, while the three-month rate for the core CPI accelerated to 2.0% from July’s 1.6%.
Combined with the stronger-than-expected employment report released on September 4 and the PPI data released yesterday (0.4% m/m; 5.4% y/y for the headline August PPI), today’s CPI report reinforces expectations of a 25bps Fed rate increase at the September 15-16 FOMC meeting. The fed funds futures market is currently pricing in an 86.5% probability of a 25bps rate hike versus 69.4% just before the CPI release.
Energy prices jumped 2.1% in August, the first m/m rise in three months, reversing a 1.5% decline in July. The y/y rate accelerated to 16.3%, the highest since May, from July’s 14.7%. The m/m increase reflected price rebounds of 10.1% (52.0% y/y) in fuel oil and 3.9% (27.4% y/y) in gasoline. In contrast, natural gas prices fell 1.1% (+4.4% y/y) in August following two successive m/m gains, and electricity costs slipped 0.2% (+3.8% y/y), the second m/m decrease in three months.
Food prices edged up 0.1% (2.7% y/y) in August, the fifth straight m/m increase, after a 0.1% uptick in July. Food-at-home prices were essentially unchanged (+2.2% y/y) following a 0.1% July dip. Within this category, prices of dairy & related products (+0.3%; -0.3% y/y), nonalcoholic beverages & beverage materials (+0.2%; +3.7% y/y), meats, poultry, fish & eggs (+0.1%; +1.1% y/y), and other food at home (+0.1%; +2.4% y/y) increased m/m in August, while prices of fruits & vegetables slid 0.4% (+3.2% y/y), the third consecutive m/m slide, and cereals and bakery products held steady (+2.6% y/y) following a 0.2% July rise. Meanwhile, food-away-from-home prices rose 0.3% (3.4% y/y) in August after rising at the same rate in July.
Goods prices less food & energy inched up 0.1% (0.7% y/y) in August after a 0.2% rebound in July. The m/m increase reflected price gains of 0.6% (6.3% y/y) in tobacco & smoking products, 0.4% (-2.3% y/y) in used cars & trucks, 0.3% (0.6% y/y) in new vehicles, and 0.1% (1.6% y/y) in alcoholic beverages. Prices of medical care commodities, however, fell 0.2% in August (-2.7% y/y), the sixth straight m/m fall; apparel prices held steady (+3.6% y/y).
Services prices less energy rose 0.3% in August on top of a 0.2% rise in July, with the y/y rate steady at 3.0%. Shelter prices grew 0.3% (3.0% y/y) in August after a 0.1% increase (3.2% y/y) in July, reflecting price gains of 2.4% (3.2% y/y) in lodging away from home, 0.2% (2.7% y/y) in rent of primary residence, and 0.2% (3.1% y/y) in owners' equivalent rent of residences.
