FX.co ★ U.S. Core CPI Inches Higher in September, Signaling Persistent Inflation Pressures

The U.S. Core Consumer Price Index (Core CPI) continued its upward trajectory in September 2026, underscoring ongoing inflationary pressures in the world’s largest economy. According to the latest data, updated on 14 October 2026, the Core CPI index rose to 338.90, up from 337.77 in August 2026.

The increase in the Core CPI – which excludes volatile food and energy components and is closely watched as a gauge of underlying price trends – suggests that inflationary forces remain embedded in the U.S. economy. While the month‑to‑month rise appears moderate, the new reading reinforces the view that price growth is not yet cooling decisively.

Investors and policymakers will be parsing the September Core CPI print for clues about the future path of interest rates and broader monetary policy, as persistent core inflation can influence central bank decisions and financial market expectations in the months ahead.
