Recent hotter-than-expected October CPI data, with headline prices rising 0.4% and core at 0.3%, has tightened the contest between no change (52.5% implied probability) and a 25 basis point hike (47.5%) at the January 2027 FOMC meeting. Persistent shelter and food costs, combined with a solid labor market showing 4.1% unemployment and steady job gains, support trader views that the Fed may extend tightening beyond the widely anticipated December move. Divergent signals from officials—such as Governor Waller's openness to larger hikes versus President Williams' caution on further 2027 action—underscore the data-dependent path ahead. The December FOMC and subsequent inflation releases remain key swing factors for January pricing.
