US core CPI rose 0.3% mom in October for a third consecutive month, exceeding expectations of 0.2% and underscoring persistent underlying inflation pressures. Headline CPI moderated from 0.6% mom to 0.4%, but also exceeded the 0.3% consensus. The divergence reflects a sharp slowdown in energy inflation that helped contain the overall index, while price pressures across several services categories continued to resist moderation. The failure of core CPI to ease suggests that underlying disinflation has yet to regain convincing momentum, despite the improvement in headline inflation.
Within the core index, services inflation outside housing remained a notable source of pressure. Services excluding rent of shelter accelerated from 0.3% to 0.5%, even as shelter inflation slowed from 0.4% to 0.3%. Transportation services inflation increased from 0.6% to 0.8%, including a rise in motor vehicle insurance from 0.1% to 0.7%. Recreation prices accelerated from 0.5% to 0.8%, while medical care inflation rose from 0.1% to 0.3%, with hospital services increasing 0.8%. Goods prices provided some offsetting relief, as core commodities inflation eased from 0.3% to 0.2%, helped by used-car prices falling 1.2% after rising 0.7% in September. However, improvements in shelter and goods were insufficient to reduce overall core inflation.
Headline inflation slowed primarily as energy price increases moderated sharply. The energy index rose 0.7% in October after surging 5.2% in September, while gasoline inflation eased from 9.1% to 1.0%. Electricity prices increased 0.9%, although natural gas prices declined 0.8%. Meanwhile, food inflation accelerated from 0.0% to 0.5%, partly offsetting the energy relief. Grocery prices rose 0.4%, while food away from home increased 0.5%, including a 0.7% rise in full-service restaurant meals. Shelter also contributed more than 30% of the monthly headline CPI increase despite its slower rate of growth. The composition indicates that the headline moderation was concentrated in energy, rather than reflecting a broad-based easing in consumer prices.
October’s figures leave the underlying inflation outlook uncertain. Three consecutive monthly core readings of 0.3% suggest that price pressures are proving more persistent than markets anticipated, particularly across non-housing services. Earlier on Tuesday, Federal Reserve Governor Christopher Waller warned that a 50bps December rate hike should be considered if core CPI remained around 0.3% mom or higher, although his remarks preceded the release and do not establish the Fed’s eventual response. The Bureau of Labor Statistics was also unable to publish most October year-on-year CPI changes because October 2025 index data were unavailable following the government funding lapse. For now, the monthly figures provide a clear distinction: headline inflation is cooling as energy pressures ease, but core inflation has not yet demonstrated a sustained improvement.

Key Takeaways
- US core CPI held at 0.3% mom for a third consecutive month, exceeding expectations of 0.2%, while headline inflation slowed from 0.6% to 0.4% but also beat forecasts.
- Non-housing services inflation remained persistent, with services excluding rent of shelter accelerating from 0.3% to 0.5%, offsetting easing shelter and core goods prices.
- Energy inflation slowed sharply from 5.2% to 0.7%, helping headline CPI moderate, but food inflation accelerated from 0.0% to 0.5%, leaving underlying disinflation unconvincing.
