Recent U.S. CPI data show headline inflation holding at 3.4% year-over-year through August 2026, with the seasonally adjusted monthly gain at 0.4%, driven by energy and shelter components while core measures eased slightly to 2.4%. The Federal Reserve’s September Summary of Economic Projections raised the median 2026 PCE inflation forecast to 3.7% and core PCE to 3.4%, alongside expectations for additional federal funds rate hikes this year. Traders are monitoring the September CPI release scheduled for October 14 for signs of further persistence or moderation. Elevated readings reflect ongoing pressures from services and commodities, with market-implied odds pricing a low probability of peaks exceeding 4.5% in any 2026 reading.
