The essentials
Rate-hike odds shift sharply lower after August PCE inflation disappoints on the downside.
Market probability of an October Federal Reserve rate hike dropped from 51% to 37% following the release of cooler-than-expected inflation data in the August Personal Consumption Expenditures report. The probability of the Fed holding rates steady in October increased to 60.7%, reflecting investor reassessment of monetary policy timing.
August's PCE inflation came in at 3.4% year-over-year, falling below economist expectations of 3.7%. Core PCE inflation held steady at 3% annually, also undershooting the forecast of 3.3%. These figures signal meaningful deceleration in headline inflation even amid ongoing geopolitical pressures affecting energy markets.
U.S. Treasury yields rose despite the cooler-than-expected inflation data, indicating market complexity in interpreting policy implications. The Fed had raised interest rates by 0.25% on September 16, 2026, marking action amid elevated inflation concerns. The shift in October rate-hike probabilities reflects how markets are now pricing the inflation trajectory in light of recent PCE results and their implications for Federal Reserve Chair Kevin Warsh's policy deliberations.

Inflation easing reshapes expectations for near-term Fed action
The August PCE report triggered a significant repricing of Fed rate-hike probabilities. Market odds of an October hike collapsed from 51% to 37%, while probability of a rate hold jumped to 60.7%. This swift recalibration reflects how markets interpret inflation cooling as reducing the urgency for additional rate increases in the near term.
Softer inflation provides Warsh with additional flexibility on timing
August PCE inflation at 3.4% undershoots 3.7% expectations, while core PCE at 3% beats 3.3% forecast, signaling the inflation trajectory that Fed Chair Warsh is monitoring. These results provide breathing room on rate decisions, though treasury yields still rose, reflecting ongoing market complexity in assessing policy paths amid geopolitical headwinds.
