Persistent inflation remains the dominant driver of trader sentiment on the timing of any Fed rate cut. The September 2026 CPI report, released October 14, showed a 0.6% monthly rise and 3.7% year-over-year increase—above expectations—with core CPI at 2.6% and energy prices surging 5.2% amid ongoing geopolitical pressures. This followed the Fed’s September quarter-point hike to the 3.75-4.00% target range and reinforced FOMC projections for at least one additional hike by year-end. Market pricing now assigns high probability to a hold at the October 27-28 meeting and a potential December increase, pushing back expectations for easing. Traders monitor upcoming labor data and the December FOMC for any shift in the rate path.
