    Fed Rate-Hike Odds Reach 90% Following 3.4% August CPI Print

    Question

    Fed Rate-Hike Odds Reach 90% Following 3.4% August CPI Print

    Direct answer

    Persistent inflation data has forced a reassessment of short-term borrowing costs. August headline CPI registered at 3.4% year-over-year while core consumer prices expanded 0.3% month-over-month, supported by energy sector cost pressure linked to Middle East tensions. Front-end yields face upward pressure as interest rate traders assign a 90% probability to a quarter-point rate hike. The shift increases funding friction for leveraged capital expenditures, housing credit, and long-duration equity valuation multiples.
