Methodology revisions and energy shocks shape August PCE inflation report

Key points

• August headline PCE inflation rose 3.4% year-over-year, and core PCE (excluding food and energy) rose 3.0%, both lower than the 3.7% and 3.3% forecasts, respectively.
• The Bureau of Economic Analysis revised its methodology for legal services, software, and portfolio management, which lowered the core July PCE level by 0.36 percentage points.
• Energy costs, particularly gasoline (up 4.4%) and transportation services (up 1.4%), drove the monthly increase, reflecting the impact of the war in Iran.
• Consumer spending rose 0.9% in August, stronger than expected, but the personal saving rate dropped to 4.1%, a near four-year low, as households drew down reserves.
• Second-quarter GDP was revised sharply higher to 2.2% annualized, up from 1.5%, driven by consumer and government spending.
• Markets priced in a lower probability of a Federal Reserve rate hike in October, shifting expectations to December, following comments from New York Fed President John Williams.

Background

In July 2026, US inflation held at 3.7% year-over-year, with core PCE at 3.3%, above the Fed's 2% target. In early September, August CPI data showed core inflation rising 0.3% to 2.4% year-over-year, fueling bets on a Fed rate hike. The current PCE report follows these trends, with methodological revisions and energy shocks influencing the final numbers.

How outlets are covering it

CNBC emphasizes the lower-than-expected PCE figures and the impact of BEA methodology revisions, noting that these changes lowered the core July PCE level by 0.36 percentage points. CNN highlights the stubborn nature of inflation, attributing the monthly increase to the war in Iran and rising energy prices, while also noting the drop in the personal saving rate to 4.1%. Both outlets agree that the Fed is likely to hold rates in October, with a potential hike delayed until December, but CNN places more emphasis on the consumer squeeze and the unsustainable pace of spending relative to income growth.

Why it matters

The August PCE report provides critical data for the Federal Reserve's interest rate decisions. Lower-than-expected inflation figures, driven by methodology revisions, may reduce pressure for immediate rate hikes, but persistent energy costs and strong consumer spending suggest that inflation remains a concern. The drop in the personal saving rate indicates that households are under financial stress, which could impact future consumer spending and economic growth. The revised GDP figures suggest a stronger economy, which may influence the Fed's approach to monetary policy in the coming months.

What to watch

The Federal Reserve is expected to hold rates in October, with a potential hike delayed until December. The next monthly jobs report is due out Friday, with economists expecting the US economy added 94,000 jobs in September, with a jobless rate staying low at 4.1%. Further PCE data and consumer spending trends will be closely watched to assess the impact of energy prices and methodology revisions on inflation.
