September PPI YoY data, due October 15, shows a dispersed distribution of trader probabilities centered on 5.4–5.9% outcomes, reflecting uncertainty over energy-driven goods prices and tariff pass-through effects. The August print rose 5.4% year-over-year on a 0.4% monthly gain, led by a 4.2% surge in final-demand energy (including a 24.1% jump in diesel) and 1.1% goods advance, while services added just 0.1%. Analysts project roughly 0.5% monthly headline growth for September, with core at 0.3%, amid Middle East supply risks and persistent input-cost pressures that could lift upstream readings before feeding into consumer inflation. This release precedes key Fed deliberations and will clarify whether elevated wholesale trends persist or moderate.
