- Surging energy costs drive headline inflation higher
- Core inflation accelerates as services pressures persist
- Analysts flag renewed price pressures
- Fed faces tougher policy choice ahead of midterms

US inflation accelerated in September, adding to the pressure on Federal Reserve policymakers ahead of next month’s midterm elections, although the prospect of another interest rate hike remains uncertain.
Data from the Bureau of Labor Statistics showed headline CPI rose 0.6% m/m, matching expectations and accelerating from 0.4% in August. Annual inflation increased to 3.7% from 3.4%, exceeding forecasts of 3.6%.
Gasoline prices jumped 9.1% on the month, accounting for more than half of the increase in headline CPI. Energy prices overall climbed 5.2%, following a 2.1% rise in August.
Shelter costs increased 0.4% m/m, up from 0.3%, while food prices were unchanged. Food away from home rose 0.2%, partially offset by a 0.1% decline in food at home.
Core CPI, which excludes food and energy, rose 0.3% m/m (0.335% unrounded), above the 0.2% forecast but matching August’s rounded increase. Annual core inflation accelerated to 2.6%, exceeding expectations of 2.5% and the previous reading of 2.4%.
Recreation, used vehicles, education, airline fares, medical care and apparel contributed to the increase, while communication prices provided a partial offset.
More concerning for policymakers was the acceleration in underlying services inflation. Supercore CPI, which excludes shelter from core services, rose 0.422% m/m, potentially reviving debate over an October rate hike.
Within shelter, owners’ equivalent rent (OER) increased 0.35% m/m, up from 0.19% in August, while rent of primary residence rose 0.2%. Lodging away from home increased 2.0%, easing from 2.4% previously.
Barclays economist Pooja Sriram suggested the OER acceleration resembled previous March–September seasonal cohort distortions. “Historically, OER has settled lower in subsequent months,” she noted.
Core goods prices rose 0.25%, led by new and used vehicles. Sriram said that while tariff pass-through was largely complete, renewed price pressures could reflect higher freight and transportation costs being passed on to consumers.
Ahead of Wednesday’s inflation data, another Fed rate hike before the midterms appeared unlikely, despite persistent price pressures.
Dr Thomas Gitzel, chief economist at VP Bank, argued that the slightly stronger annual core inflation reading offered little evidence of broader second-round effects.
“This is precisely why the US Federal Reserve will remain cautious regarding its future interest rate policy,” he said.
Barclays’ Sriram struck a more cautious note, warning that the figures offered policymakers little comfort.
“Risks we have flagged for some time, including energy pass-through into core prices, resilient consumer spending, and AI-related price pressures, increasingly appear to be showing up in the inflation data.”
Nevertheless, the bar for further tightening ahead of November’s vote remains high.
Attention now turns to Thursday’s PPI report for evidence of pipeline inflation pressures, particularly whether rising diesel and transportation costs are feeding through to producer prices.
