Rate Odds Tilt to September Hold as Warsh Eyes Inflation

Markets now price a 65% probability the Federal Reserve holds interest rates in September, a sharp reversal from near coin-flip odds just weeks ago, with Fed Chair Kevin Warsh's Jackson Hole speech looming.

Lead

The rate odds chart has moved decisively in the past three weeks. As of August 19, CME Group's FedWatch tool puts the probability of a September rate hold at 65.4%, with a 25-basis-point hike to 3.75%-4.00% priced at roughly 35%. That is a notable shift from the near-even split traders were pricing after the July 29 Federal Open Market Committee meeting, when the committee voted 9-3 to hold the federal funds rate at its current 3.50%-3.75% target range. The recalibration reflects a softer-than-feared July inflation print, but the story is far from settled: Fed Chair Kevin Warsh takes the podium at Jackson Hole on August 28 for his first major policy speech, and markets are watching closely for any reset of expectations.

Why Did Rate-Hold Odds Rise So Sharply?

The shift traces directly to July's consumer price index release. Headline CPI rose just 0.1% in July on a seasonally adjusted basis, bringing the year-over-year rate to 3.4%. Core CPI, which strips out food and energy, climbed 0.2% for the month and 2.5% year-over-year - a figure close enough to the Fed's 2% target to ease the urgency for immediate tightening. With the next CPI report not due until September 11, five days before the FOMC convenes, markets have had little fresh data to justify repricing back toward a hike.

The July hold decision itself also played a role. Even with three dissenters - Cleveland's Beth Hammack, Minneapolis's Neel Kashkari, and Dallas's Lorie Logan - all favoring an immediate 25-basis-point increase, the majority's preference for patience gave rate futures a temporary anchor. Bond traders interpreted the 9-3 split as evidence that the committee's center of gravity still leans toward caution, not acceleration.

What Does Kevin Warsh Signal for Interest Rates?

Warsh, confirmed as Fed Chair on May 13 in a 54-45 Senate vote, has delivered a consistent message since taking office: the Fed will not declare victory on inflation prematurely. His two-word formulation - "no tolerance" - set the tone in congressional testimony in July, and he followed it with a statement that the Fed is "not constrained by market prices," a phrase Bloomberg characterized as hawkish and likely to reprice rate expectations higher over time.

That framing keeps the 35% hike probability from collapsing further. Warsh has also launched five internal policy task forces, signaling he intends structural changes to how the Fed communicates and operates, including a retreat from the forward guidance framework his predecessors relied on. That deliberate opacity raises the stakes for August 28, when his Jackson Hole address will be parsed word by word for clues on the September outcome.

The September 16 meeting carries additional weight because it includes an updated Summary of Economic Projections and the quarterly dot plot. FOMC participants currently project year-end rates between 3.6% and 4.1%, a wide band that reflects genuine internal disagreement. Markets are pricing in two 25-basis-point hikes in total for 2026, with no further movement through 2027.

How Does Persistent Inflation Risk Complicate the Hold Case?

Energy prices remain the principal wild card. Elevated crude costs tied to continued Middle East tension have filtered into headline inflation and kept supply-side price pressure elevated even as demand-side indicators cool. The Fed's own PCE inflation forecast for 2026 sits at 2.2%, a figure that implies the committee believes the current rate level is broadly appropriate - but that projection was set before the latest energy spike, and it may require revision in the September dot plot.

GDP growth projections have actually moved up, with FOMC participants now forecasting 2.2% expansion for 2026, compared with earlier estimates. Job gains have remained steady enough to absorb workforce growth without generating fresh wage-push inflation. That combination - solid growth, cooling core inflation, elevated energy risk - is precisely the environment that argues for holding rather than hiking, but it leaves no margin for error if energy costs remain elevated through September.

Warsh's task forces may also be evaluating the Fed's inflation-averaging framework, introduced under previous leadership. Any signal at Jackson Hole that the committee is moving away from average inflation targeting could be read as more hawkish, regardless of what the September decision ultimately is.

Outlook

With the rate odds chart now settled around a 65%-35% hold-hike split, the September 16 meeting is consequential but not yet a foregone conclusion. The next pivotal inputs arrive in sequence: Warsh's Jackson Hole address on August 28 will set the interpretive frame; the September 11 CPI report will provide the last major data point before the decision. If core inflation prints at 0.2% or below for a second consecutive month, the hold case solidifies and market odds could approach 75%-25% by the time the committee convenes. A hotter print, or hawkish rhetoric from Warsh in Wyoming, would rapidly narrow that gap. For now, the balance of evidence - cooling core prices, a divided but hold-leaning committee, and an incumbent Fed Chair who has not yet signaled a September shift - keeps a hold as the base case, though the margin for surprise remains real.
