Federal Reserve Chairman Kevin Warsh used his first Jackson Hole keynote to declare the Fed's 2% inflation target non-negotiable, pointing to headline PCE inflation of 3.7%. Markets responded immediately, pushing up the odds of a September rate hike.
Kevin Warsh delivered the speech markets had been waiting for. In his first Jackson Hole keynote as Federal Reserve Chairman, Warsh put inflation front and center, citing a headline PCE rate of 3.7% year-over-year for July and making clear the Fed's 2% target isn't a suggestion.
Markets heard the message. The probability of a rate hike at the upcoming September FOMC meeting jumped to roughly 50-60% after the speech, a sharp increase from where odds had been sitting before Warsh took the stage.
The numbers behind the hawkish tone
The Personal Consumption Expenditures price index, the Fed's preferred inflation gauge, came in at 3.7% year-over-year for July, nearly double the central bank's target. But the six-month annualized change paints an even less comfortable picture at 4.1%, suggesting price pressures may actually be accelerating rather than cooling.
Over 54% of PCE components increased at an annualized rate above 3% over the past year, the most striking data point in the release. According to Crypto Briefing: "The 2% PCE target is a 'firm, fixed target.'" He acknowledged that some recent readings have shown modest easing trends, but he distinguished between directional improvement and actual progress toward price stability.
A different playbook from his predecessor
Warsh succeeded Jerome Powell as Fed Chairman in late May 2026, and his Jackson Hole appearance on August 28 marks the clearest articulation yet of how his leadership will differ from Powell's. Under Powell, the Fed leaned heavily on telegraphing its intentions to markets, sometimes months in advance.
He instead argues that explicit forward guidance should be reserved for crisis situations, not deployed as a routine tool during normal policy operations. The speech also corrects course from Warsh's July press conference, which had left market participants unsure of his true policy leanings.
What the September decision hinges on
The surge in rate hike expectations reflects a real shift in how markets price the near-term policy path. Before the speech, there was a credible case that the Fed could hold steady through the fall while waiting for more data.
Whether 3.7% PCE inflation marks a plateau or a waypoint remains the open question. If the 4.1% six-month annualized rate proves the more accurate signal, Warsh's remarks suggest he is prepared to do more than a single rate hike to bring prices back toward target.
