FX.co ★ U.S. Inflation Accelerates in September as Monthly CPI Rises to 0.6%

U.S. consumer price growth picked up pace in September 2026, with the Consumer Price Index (CPI) rising 0.6% month-over-month, up from a 0.4% increase in August 2026. The latest data, updated on 14 October 2026, signal a reacceleration in price pressures after a more moderate reading in the previous month.

On a month-over-month comparison basis, the “actual” figure reflects the change in prices in September versus August, while the “previous” figure measures August’s change versus July. The move from 0.4% to 0.6% indicates that inflationary momentum strengthened as the third quarter closed, a development likely to draw close attention from investors and policymakers monitoring the trajectory of U.S. price growth.
