US PCE inflation firms in September 2026 as real spending barely rises

US headline PCE prices rose 0.49% in September 2026 from August and 3.65% from a year earlier, according to calculations from BEA price indexes. Core PCE inflation, excluding food and energy, was 0.32% monthly and 3.12% annually. Both annual rates firmed, while personal income and nominal spending growth slowed.

Annual headline inflation increased from 3.44% in August, and core inflation rose from 3.03%. Both measures had also risen between July and August. September therefore extended the recent firming, although both annual rates remained below their May readings. The positive monthly changes reinforced the evidence of continuing price pressure, rather than a decline in price levels.

Personal income increased 0.20% in September, down from 0.30% in August, while nominal personal consumption expenditures grew 0.51%, compared with 0.87%. Spending growth thus continued to outpace income growth despite slowing. BEA's September release reported that disposable personal income increased 0.2% and that the personal saving rate stood at 3.8%.

Higher spending largely reflected prices

BEA attributed the income increase primarily to compensation and government social benefits, with private wages and salaries leading compensation gains and Medicare leading the benefits increase. Its release reported increases in current-dollar spending on both goods and services, with the larger dollar increase in services. These are spending changes, not measures of each category's contribution to inflation.

The clearest household-demand signal was the contrast between nominal spending growth and BEA's reported increase of less than 0.1% in real PCE. Higher outlays largely reflected higher prices rather than a substantial increase in consumption volume. With income growth also slowing, the figures suggest limited additional room for households to expand purchases without adjusting saving or other financial resources.

Inflation's persistence matters for purchasing power: positive price growth continues to erode what a given dollar of income buys. For the Federal Reserve, firmer annual headline and core readings could complicate an assessment of easing inflation pressure, while nearly flat real consumption offers a softer demand signal. That tension does not establish the next policy decision.

The September release reported annual headline inflation of 3.6% and core inflation of 3.1%. The index-based figures above reflect the stored-series vintage; the release-specific spending and income explanations are attributed to that release rather than treated as revised estimates.
