Recent hotter-than-expected October 2026 CPI data, with headline inflation rising 0.4% month-over-month and core measures advancing 0.3%, have reinforced trader expectations for additional Federal Reserve tightening at the December FOMC meeting. Solid October employment gains of 165,000 jobs and a stable 4.1% unemployment rate underscore resilient labor conditions that limit room for policy easing. Market-implied odds heavily favor a 25-basis-point hike, reflecting the current 3.75%-4% federal funds target range after the September increase and hawkish signals from Chair Kevin Warsh. Upcoming December data releases and the policy statement will likely serve as the final catalysts before resolution.
