The United States Core PCE Price Index, the Federal Reserve’s preferred gauge of underlying inflation, rose 0.3% month-over-month in September 2026, matching the revised 0.3% increase recorded in August 2026. The data, updated on 29 October 2026, indicate that underlying price pressures remain steady rather than easing, as Core PCE excludes the often-volatile food and energy components.
On a month-over-month basis, the latest reading confirms that price growth in September advanced at the same pace as in August, underscoring a continuation rather than an acceleration or cooling of core inflation trends. The comparison framework shows “Actual” as the change in September versus August, while the “Previous” figure reflects August’s change relative to July, both landing at 0.3%.
The back-to-back 0.3% monthly gains will likely be closely watched by markets and policymakers as they assess the persistence of inflation in the U.S. economy. While the data do not show a renewed flare-up in price increases, they also offer little sign of a decisive slowdown in core inflation momentum.
