Fed Rate-Hike Odds Top 85% After Core Inflation Accelerates

Key Facts

1September rate-hike odds exceeded 85% after standing near 72% before the inflation data.
2Core CPI rose 0.3% month over month in August versus a 0.2% forecast.
3The Fed held rates at 3.50%-3.75% in July, with 3 members preferring a 25-basis-point increase.
4The next meeting is scheduled for September 15-16, 2026.

Market-implied odds of a September Federal Reserve rate increase moved above 85% after the inflation release, from about 72% beforehand. The repricing followed a 0.3% rise in core CPI in August, above the market forecast of 0.2%.

Headline CPI increased 0.4% in August and 3.4% from a year earlier, while annual core inflation was 2.4%. CPI should not be compared mechanically with the Fed's 2% target, which is defined using the personal consumption expenditures index, but it provides a timely signal on the direction of price pressures.

The University of Michigan survey added another cautionary signal: consumers' year-ahead inflation expectation jumped from 4.0% in August to 4.6% in September's preliminary reading. This is a measure of household expectations, not realized inflation, but policymakers watch it because persistent expectations can influence wage, spending and pricing decisions.

Energy remained an additional risk. Brent settled at $104.61 a barrel after nearing $110 intraday, while the August CPI report showed the energy index rising 2.1% for the month and gasoline increasing 3.9%. Persistently high energy costs can slow disinflation even when parts of the core basket are calmer.

The Fed held its target range at 3.50%-3.75% in July on a 9-3 vote, with 3 members preferring a 25-basis-point increase. The economy subsequently added 162,000 jobs in August, while unemployment held at 4.1%, leaving the labor market firm ahead of the next decision.

The next FOMC meeting is scheduled for September 15-16, 2026, not September 18. The decision is due on September 16 alongside updated economic projections, which may help markets judge whether any increase would be a one-off move or the start of a longer tightening path.

A rate increase would tighten short-term financial conditions and could feed into household and business borrowing costs, while a hold would surprise markets relative to current pricing. Market probabilities are not guarantees: they move with futures prices and incoming data and do not represent a Fed commitment.
