Recent strength in energy prices, particularly gasoline amid ongoing Middle East geopolitical tensions and elevated oil levels near $90 per barrel, has positioned the 0.6% monthly headline CPI outcome as the market-implied favorite at 46% probability for September 2026. August’s 0.4% month-over-month print, driven by a 3.9% gasoline increase and firm services components, has informed trader expectations for further sequential pressure, with forecasts from firms like TD Securities highlighting an approximate 8% gasoline surge and firmer food prices supporting a 0.54% headline gain. Core measures are projected to moderate toward 0.2%, tempering upside risks. The September CPI release on October 14 will resolve the market, with outcomes clustered around 0.5–0.7% reflecting uncertainty over energy pass-through versus cooling shelter and goods trends.
