Recent September ISM Manufacturing PMI data at 54.5, slightly below the 55.0 consensus, underscore resilient manufacturing expansion for a ninth straight month, with new orders rising to 55.3 and employment advancing to 52.7 while production moderated to 56.7. Surging input costs, with the prices index jumping to 77.9 amid steel and aluminum tariffs plus petroleum pressures tied to Middle East developments, alongside trade policy uncertainty, temper the outlook and support the market-implied clustering around 53–56 for October. Low customer inventories and growing backlogs point to potential production support, yet geopolitical and cost headwinds create competitive dynamics across the closely matched probability bands. The October release, due early November, will clarify momentum against these factors.
