The Warsh Jackson Hole rate hike probability story is simpler than the markets want it to be: a Fed chairman told the world he is not satisfied with inflation progress, and traders listened. According to CNBC, the CME Group‘s FedWatch tool showed traders raising the probability of a September rate hike to 55.7%, roughly 20 percentage points higher than the day before. A separate reading of the same market put the figure at 59.5%, up from 35.5% the prior session. The direction is unambiguous, whatever the precise figure.
What Warsh Actually Said at Jackson Hole
Kevin Warsh’s debut address at the Kansas City Fed’s annual symposium in Wyoming was, by his own framing, a data-driven assessment rather than a policy commitment. But the language carried weight. ‘We must be confident that underlying inflation is moving to our objective, clearly and at sufficient speed. Otherwise, we have work to do,’ he said in what The Wall Street Journal reported as his first speech as Fed chairman.
He described credit and loan markets showing few signs of policy restraint, and said he would ‘be hard-pressed to describe broad financial conditions as restrictive’ despite some strain in housing and agriculture. Business investment, he noted, is growing at its fastest pace since 2021. Credit spreads are near the low end of their historical range. The prevailing read of these comments (that Warsh is tilting hawkish) is probably correct. The question worth asking is whether the market is now pricing in too much certainty, too fast.
Warsh also set aside one of the more persuasive arguments for holding rates steady. Moderate wage growth has traditionally been read, in the Fed’s own models, as a signal that inflation should moderate over time. Warsh dismissed that signal directly: wage growth ‘has not proven a reliable indicator of future inflation for a very long time,’ he said. Removing that buffer from the dovish case narrows the intellectual room for patience considerably.
The PCE Data the Consensus Glossed Over
The Warsh Jackson Hole narrative arrived alongside a Personal Consumption Expenditures (PCE) reading that did not help the patience case. The Bureau of Economic Analysis reported monthly PCE at 0.2%, against a consensus estimate of 0.1%. That miss came despite the BEA reporting a 2.7% decline in gasoline prices that consumers did not actually see at the pump, which means the underlying core pressure was, if anything, understated by the headline.
Year-over-year PCE inflation has now run above the Fed’s 2.0% target for 65 consecutive months since March 2021. About half the items in the Fed’s preferred inflation basket are rising faster than 3%. The popular counter-argument, that core CPI is running at a still-elevated 2.5% and moving in the right direction, leans on a measure the Fed itself does not treat as primary. The consensus read of this summer’s data as ‘better than expected’ is Warsh’s own phrasing, but he was careful to add that they ‘do not tell me that underlying trends have meaningfully improved.’ That qualification is doing a lot of work, and the market is only now beginning to price it.
The bull case for no hike rested on three assumptions: that financial conditions were already restrictive enough, that wage growth would contain future price pressure, and that the summer’s softer readings signalled a genuine trend. Warsh has now publicly discarded all three. That is not a hawkish lean. That is a chairman telling anyone willing to read carefully that the bar for staying put has risen.
There is a separate question the September hike probability does not resolve, and it is the one that will matter more over the next year. Warsh himself acknowledged that the economy ‘appears to have strengthened’ and has ‘held up to shocks.’ Credit spreads at the low end of their range and accelerating business investment are not the signature of an economy straining under a 3.6% policy rate. They are the signature of an economy that has absorbed that rate without blinking, and in which a meaningful portion of what looks like growth may be credit-fuelled capital spending concentrated in a single sector. Warsh did not name that sector. The market probably does not want him to.
The September meeting is the immediate test. A 20-percentage-point swing in hike odds in a single session, triggered by one speech, tells you the market had been substantially underpricing the hawkish scenario. The recalibration is ongoing.
