US Inflation Accelerates to 3.6% in September as Household Savings Rate Falls

US inflation accelerated in September 2026, according to figures released on Thursday by the Bureau of Economic Analysis, adding to pressure on households and complicating the Federal Reserve's next interest-rate decision. The Personal Consumption Expenditures price index rose 0.5% from August and 3.6% from September 2025, compared with a 3.4% annual increase in August.

The core PCE index, which excludes the more volatile food and energy components, rose 0.3% for the month and 3.1% from a year earlier. Both the headline and core annual rates remained above the Federal Reserve's 2% inflation objective. Higher energy costs contributed to the overall increase, according to contemporaneous economic reporting.

The same release showed that personal income increased 0.2% during September, while nominal personal consumption expenditures rose 0.5%. In dollar terms, spending increased by $113.1 billion. Inflation-adjusted consumer spending changed by less than 0.1%, a reminder that an increase in the cash value of purchases does not necessarily mean households bought substantially more goods and services.

Disposable personal income also rose 0.2% in nominal terms, but real disposable income fell 0.3% during the month. The personal saving rate declined to 3.8%, indicating that households saved a smaller share of disposable income. The statistical release does not establish whether the change will persist.

The data arrived one day after the Federal Reserve held its benchmark policy rate unchanged. Policymakers face an economy with elevated inflation but continued expansion in activity. The latest PCE figures describe price and spending developments already recorded in September; they are not a forecast of future inflation or a decision about December interest rates.

The next monthly personal income and outlays release is scheduled for 25 November 2026. Subsequent data, including employment and inflation figures, will help determine whether September's increase in price pressures is sustained.
