Fed Rate Hike Path Traced to Warsh's Hawkish Jackson Hole Speech

From a quiet week ahead to a policy turn

Late August previews of the week ahead for currency and bond markets put two U.S. events above everything else: Federal Reserve Chairman Kevin Warsh's first Jackson Hole keynote and the July personal consumption expenditures (PCE) inflation report, the Fed's preferred gauge.11 The question for investors was whether U.S. rates would rise, and if so, when. At that point money markets were close to fully pricing a 25 basis-point increase by December.11 Six weeks later, the answer is clear. The Fed raised rates on Sept. 16, and the Jackson Hole week is where that move took shape.31

The setup going into the week mattered. Long-dated Treasury yields had climbed to multiyear highs, and the Treasury responded by doubling the size of its long-end buyback operations to at least $4 billion each, which steadied the market.11 Ten- and 30-year yields had recently reached their highest levels since 2007. CNBC linked the selloff partly to doubts about the Fed's commitment to its inflation target and partly to worries about debt and deficits.21 Marc Chandler took the buyback expansion as a sign that the administration was worried about the Treasury market. He also noted that the step did nothing to address a budget deficit running at about 6% of GDP.18

The previews did not agree on how much Warsh would say. TD Securities strategists expected him to stick with his refusal to give guidance, while adding that markets wanted hints about his reaction function and a restatement of the Fed's inflation-fighting record.11 Chandler expected a broad, high-level speech about central banking and said it was unrealistic to think Warsh would discuss current policy settings.18 The previews also disagreed on timing. Chandler's preview said the speech would come on a Wednesday, but Warsh actually spoke on Friday, Aug. 28.121

The PCE print: sticky, with a disputed surprise

The July PCE data came out on Wednesday, Aug. 26. Headline prices rose 0.2% for the month and 3.7% from a year earlier, both 0.1 percentage point above the Dow Jones consensus.21 Core PCE, which leaves out food and energy, rose 0.2% for the month and 3.3% from a year earlier.21

Outlets disagreed on whether the core number was a surprise. CNBC and FXStreet said it matched forecasts.2123 CBS News and Morningstar, working from FactSet surveys that expected 3.2%, called it hotter than expected.2227 The gap reflects different consensus surveys, not different data, but it shaped the tone of the coverage. Both readings were unchanged from June.22 Heather Long of Navy Federal Credit Union said the U.S. "still has an inflation problem" and pointed to $4 gasoline and $5.60 diesel as signs that the Iran war was still feeding into prices.22

The report on its own did little to change policy expectations. Markets still saw only about a one-in-three chance of a September hike and considered December the likelier date.21 FXStreet had expected a muted reaction because Jackson Hole was the main event.23 That proved right.

Jackson Hole: hawkish without forward guidance

Warsh held to his position on communication. He told the symposium he was "committed to a discipline, not to a decision," said forward guidance "has overstayed its welcome," and argued that markets should not look mainly to the Fed "for their next trade."1 He also declined to set out an explicit reaction function, saying the Fed's knowledge "just doesn't extend that far—at least not yet."7

The content of the speech was hawkish all the same. Warsh said the summer's better inflation readings did not show that "underlying trends have meaningfully improved," and that the Fed had "work to do" unless it could be confident inflation was falling to target quickly enough.1 He said the Fed's "predominant focus right now should be on prices."2 He called the labor market consistent with full employment.5 He also suggested rates were not currently restraining activity, citing strong AI investment and consumer spending.4

CNBC's analysis read the speech as a reply to criticism of his unclear July 29 press conference. In it, Warsh restated the 2% PCE target as a "firm, fixed target," called short-term rates the Fed's "predominant tool," and played down AI and balance-sheet questions as factors in near-term policy.13 That point is important. Earlier, Warsh had suggested AI gains or a smaller balance sheet could justify lower rates, a view that matched President Trump's calls for cuts. Dropping those arguments put him at odds with the White House.13

The market reaction was immediate. The two-year Treasury yield rose about 8 basis points, to roughly 4.30%–4.31%, while longer yields were mostly flat or lower, a bear flattener.142 Futures-implied odds of a September hike rose to about 55%, from about one-third.154 StoneX described a dollar short squeeze that pushed gold, silver and bitcoin lower.8

Not everyone thought the speech said much. Paul Krugman called it "utterly conventional."15 Michael Strain of the American Enterprise Institute noted that Warsh had talked tough before without acting. He also said Warsh's description of the economy pointed to "a standard policy response, which is to raise interest rates."45 Strain's second point was the more useful one. The speech was a statement of conditions, and the conditions it described already called for a hike.

September: the hike arrives

On Sept. 16 the Federal Open Market Committee voted 12-0 to raise the federal funds rate by a quarter point to 3.75%–4%. It was the first increase since July 2023.31 Warsh opened his press conference by repeating the Jackson Hole test word for word and saying the committee had found it "has not been satisfied."32 He called the move a "sober decision" and repeated that he is "not in the forward guidance business."36

The new projections went further than the chairman would. CNBC reported that 12 officials expected one more hike this year, four expected two, and two wanted no change, putting the median year-end rate at 4.1%.36 Warsh again did not submit his own rate forecast.36 The result is a two-track communication system. The committee's dot plot shows a path while the chairman refuses to describe one. Markets will have to decide which signal to rely on.

Warsh also rejected the suggestion that markets had pushed the Fed into the move. Futures had priced about a 90% chance of a hike, and he said "today was our decision."39 The White House called the decision "rather unfortunate" and said it lacked a strong economic case.36 The New York Times noted that Trump did not attack Warsh personally and instead blamed other governors.33 The unanimous vote stood out after a period that included four governors dissenting in April, the most since 1992.

Since then: the data has softened

The inflation picture has eased since then. The August PCE release on Sept. 30 showed core inflation at 3.0% year over year, below the 3.3% consensus. July's core reading was also revised down to 3.0% from the 3.3% first reported.2829 So the July figure that framed the Jackson Hole week was weaker than markets thought at the time.

Minutes released Oct. 7 showed that all participants supported a higher rate range in September, with almost all seeing upside risks to inflation.35 Yahoo Finance noted, however, that economic signals have changed since the meeting.35 Warsh's next public appearance is a conversation with the IMF's Kristalina Georgieva in the coming week, alongside remarks from Governors Waller and Bowman.20

The reading

A calendar preview treated Jackson Hole and the PCE report as two separate events for traders to watch. Taken together, they changed Fed policy. The July data was steady enough to support Warsh's claim that inflation's underlying trend had not improved. He then used his speech to set a test for action without committing to a date, and three weeks later the committee met that test.

The bigger issue now is whether Warsh's approach holds up when the data turns. He has said he responds to trends, not single prints.38 The downward revision to July core PCE means one of the readings behind the hike was weaker than first reported. With the dot plot pointing to another increase and the chairman declining to give guidance, October and December will show whether the "discipline" Warsh described in Wyoming can also justify a pause.
