FX.co ★ U.S. CPI Accelerates in September, Raising Fresh Inflation Concerns

U.S. consumer prices picked up pace in September 2026, with the Consumer Price Index (CPI), not seasonally adjusted, rising 0.59% month-over-month. This marks a notable acceleration from August 2026, when prices increased by 0.32% compared with July.

The latest data, updated on 14 October 2026, underscores a strengthening inflation pulse on a month-over-month basis. The September reading shows that price pressures are building rather than easing, as each “Actual” figure reflects how much prices have changed from the previous month, while the “Previous” value captures the month-on-month change recorded in August. Investors and policymakers will be closely monitoring whether this upward momentum in CPI continues, as it could influence expectations for future interest rate moves and broader financial market sentiment.
