The United States Core Consumer Price Index (Core CPI) rose 0.3% month-over-month in October 2026, matching the revised 0.3% increase recorded in September 2026. According to data updated on 10 November 2026, the underlying inflation gauge—excluding volatile food and energy components—showed no acceleration or deceleration in price pressures compared with the prior month.
On a month-over-month basis, the October reading confirms a continuation of the same pace of core inflation as seen in September. The comparison framework indicates that the current figure reflects the change in prices from September to October, while the previous figure represented the change from August to September, both settling at 0.3%. This consistency suggests that, at least over the last two months, underlying price growth has remained stable rather than moving decisively higher or lower.
Market participants and policymakers are likely to view the steady Core CPI reading as a sign that there has been no fresh upward shock to underlying inflation in October. However, with core inflation still positive on a monthly basis, the data will remain an important input into assessments of the broader inflation trajectory and the outlook for future monetary policy decisions in the United States.
