The U.S. Consumer Price Index (CPI), not seasonally adjusted, swung back into positive territory in August 2026, posting a 0.32% month-over-month increase. This follows a marginal 0.01% decline recorded in July 2026, highlighting a notable shift in monthly price dynamics.
On a month-over-month comparison basis, the latest data show that price pressures strengthened in August compared with the previous month, when consumer prices had effectively stalled. The “actual” figure for August measures the change against July 2026, while the “previous” figure for July was calculated against June 2026, underscoring an acceleration in price growth heading into late summer.
The updated data, released on 11 September 2026, suggest that after a brief pause in July, consumer prices in the United States resumed their upward trajectory, potentially signaling renewed inflationary momentum as the third quarter progresses.
