Recent August core CPI data printed at 2.4% year-over-year following a 0.3% month-over-month rise, hotter than consensus and prompting analysts to forecast a moderation to roughly 0.2% MoM for September. This trajectory, driven by mean-reversion in services and supercore components after August’s telephone-services surge, supports the tight contest between 2.5% and 2.4% year-over-year outcomes. Energy pass-through effects and shelter cooling remain key swing factors that could shift the annual rate by a tenth, while the October 14 BLS release will resolve the market amid ongoing focus on the Fed’s preferred inflation path. Trader positioning reflects uncertainty over whether the recent monthly firmness persists or eases toward the 2% target range.
