Recent forecasts for the September 2026 CPI MoM reading center on energy-driven headline gains, with RBC Economics projecting +0.6% and TD Securities +0.54%, fueled by an anticipated near-8% gasoline increase and firmer food prices. This follows August’s +0.4% print and aligns with the market’s tight clustering around 0.5% (37.0%) and 0.6% (33.5%), where rounding effects and volatility in energy components create the primary uncertainty. Core measures are expected to moderate toward +0.2%, potentially limiting upside, though persistent supercore pressures and tariff-related goods costs introduce downside risks to the lower outcomes. The October 14 BLS release remains the key near-term catalyst shaping trader positioning ahead of resolution.
