Recent energy price volatility and tariff pass-through effects on goods represent the dominant drivers behind the dispersed market-implied odds for the September 2026 U.S. PPI YoY release. August final demand prices rose 0.4% month-over-month and 5.4% year-over-year, led by a 4.2% energy surge amid geopolitical tensions, with core goods also firming. Traders appear to price in continued upstream pressures from elevated oil and diesel costs alongside mixed services margins, producing a wide distribution peaking at 5.9%+ yet with meaningful probability mass below 5.5%. Key swing factors include the extent of commodity stabilization ahead of the October 15 release and any revisions to prior data, which could shift implied probabilities ahead of the next FOMC meeting.
