**Trader consensus for the September 2026 Core CPI month-over-month print centers on a 0.2% increase, reflecting expectations of moderation after August’s hotter-than-expected 0.3% rise.** Forecasts from major banks cluster around 0.19–0.21%, citing normalization in wireless telephone services that boosted the prior month and continued easing in shelter components. Energy-driven headline pressures are anticipated to lift the overall CPI, yet core goods and services ex-shelter trends are projected to remain contained. With the BLS release due October 14 at 8:30 a.m. ET, market-implied odds embed this base case while assigning meaningful probability to a 0.3% upside surprise that could sustain tighter policy expectations. Recent labor-market and commodity data have reinforced the view that underlying disinflation is resuming after the August bump.
