Federal Reserve Chair Kevin Warsh delivered his first Jackson Hole keynote on Friday morning, and the rates complex had repriced before the speech was over. The symposium theme was financial innovation and payments. The chair spent his time on inflation.

The substance was blunt. The 12-month change in the PCE price index stands at 3.7%, Warsh said, and the six-month change at 4.1%. Disaggregating the 199 components of that basket, 54% posted price increases above 3% over the past year, against roughly 32% in the two decades before the pandemic. Summer’s softer CPI and PCE prints, he said, do not tell him that underlying trends have meaningfully improved. His stated standard is that the Fed must be confident inflation is moving to target clearly and at sufficient speed, and that otherwise there is work to do.

The passage equity holders should read twice

It was not about prices. Warsh said he would be hard pressed to describe broad financial conditions as restrictive, and listed the evidence: credit spreads on corporate bonds and leveraged loans near the low end of their historical ranges, commercial and industrial lending standards on the easy side, low equity volatility, S&P 500 profits up more than 20% over the past year, and margins elevated against history.

That inverts the usual reflex. Strong markets are normally read as a reason for policy to stay put. A chair who reads buoyant asset prices as evidence that policy is not yet tight has turned the equity market’s own strength into part of the argument for a higher funds rate. On the other side of the mandate he offered no relief: unemployment at 4.1%, claims near their lowest in decades, and a labour market he called consistent with full employment. Nothing there asks the Fed to cut.

Rates traders took the point. The two-year Treasury yield jumped 13 basis points to 4.352%, the 10-year rose about five to 4.724%, and the 30-year added under two to 5.209%. CME FedWatch put the probability of a quarter-point hike at the 15-16 September meeting at 57.5%, up from 35.4% on Thursday. Barclays changed its call outright, moving to quarter-point increases in September and December.

The number nobody traded

Chicago PMI landed at 47.1 for August, against a 57.8 forecast and 57.6 in July. A 10.5-point drop is a violent move for a diffusion index, and it puts the barometer below the 50 line for the first time in four months. On any ordinary Friday that print pushes yields lower.

Yields rose instead. Part of the reason is what a diffusion index measures: breadth, not magnitude. It records how many firms in one region reported worse conditions, not how far output fell. The larger reason is that Warsh had spent several minutes of the same morning arguing that policy should not be set off isolated data points, and that trends matter most. The market applied the principle immediately, to the one number available to test it on.

For the innovation theme itself, the keynote produced little of direct equity consequence. Warsh’s technology section was about artificial intelligence rather than payments, and he framed it as an open question set for a Fed task force whose conclusions, he said, have no bearing on current policy.

Friday’s tape

The S&P 500 closed at 7,711.76, down 0.25%. The Nasdaq Composite fell 0.52% to 26,402.42, and the Dow was effectively flat at 53,559.99. All three still finished the week higher. Attribution should stay honest here: the two largest single-stock moves had nothing to do with either the speech or the survey, with PayPal down 12.7% after reports that a buyout consortium walked away, and Marvell down 10.3% on a good quarter that was not good enough. Nvidia gave back 4.6% of Thursday’s gain. What the macro genuinely did on Friday shows up in the two-year yield, not the index.
