The U.S. Core Consumer Price Index (Core CPI) inched higher in August 2026, underscoring ongoing underlying inflation pressures in the world’s largest economy. The index rose to 337.77 in August from 336.79 in July 2026, according to data updated on 11 September 2026.

While the move represents a modest month-on-month increase in the core gauge, which excludes volatile food and energy components, it reinforces the picture of inflation that remains elevated rather than easing decisively. The rise from July’s level suggests that price growth in key categories of consumer spending continues to advance rather than plateau.

Investors and policymakers are likely to scrutinize the August Core CPI reading for signals on the trajectory of inflation into the latter part of the year, with the latest figures providing another data point for assessing the balance between growth and price stability in the U.S. economy.
