FX.co ★ U.S. Core CPI Edges Higher in May, Underscoring Stubborn Inflation Pressures

The U.S. Core Consumer Price Index (CPI) inched up in May 2026, signaling that underlying inflationary pressures remain present in the world’s largest economy. According to the latest data, updated on 10 June 2026, the Core CPI index rose to 336.12 in May from 335.42 in April 2026.

While the move represents a modest month-on-month increase, it underscores that core inflation — which excludes volatile food and energy components — is still drifting higher rather than stabilizing. The May reading will be closely watched by investors and policymakers as they assess the trajectory of price pressures and their potential implications for interest rate expectations and broader financial markets.
