Recent September ISM Manufacturing PMI data at 54.5, just below consensus, underscores steady expansion for a ninth straight month amid firmer new orders and employment but softer production and sharply higher input prices at 77.9. Persistent tariffs on steel, aluminum, and imports, alongside Middle East-related petroleum costs, have elevated the Prices Index and tempered respondent sentiment, with negative comments citing policy uncertainty and supply-chain strains. Low customer inventories and rising backlogs support potential October resilience, though trade frictions and geopolitical risks remain key swing factors. The November 2 release will clarify whether momentum holds near the mid-50s range or shifts amid these pressures, with market-implied odds reflecting balanced trader views on the outcome.
