Warsh's 60% Hike Odds: Why Jackson Hole Repaired Fed Credibility Before It Changed Rates

John Grey — Macro & cross-asset desk

The Federal Reserve got something it has not had much of this summer: a bond market willing to believe its chairman. After Kevin Warsh used his first Jackson Hole keynote to say inflation was still too high and the Fed might have “work to do,” traders lifted the probability of a September rate increase to roughly 60%, from about 40% before the speech. The contrarian read is that this was not a rate-hike announcement. It was a credibility repair operation, and the repair may matter more than the meeting at which the Fed eventually moves.

Warsh gave investors a firmer inflation anchor without giving them the detailed reaction function they had demanded. That combination sounds contradictory, but it is the defining feature of the new Fed regime. The chair is trying to make the institution predictable about its objective while keeping its decisions discretionary about timing. Markets can price a higher chance of a hike when the policy target is clearer, even if the path to the next meeting remains deliberately opaque.

In his Aug. 28 speech, “In Our Time,” Warsh described a U.S. economy that was stronger than the market's recent anxiety suggested. Real consumer spending had increased by more than 2% over the past four quarters, private domestic final purchases were running near a 3% pace for the year, and the jobless rate was 4.1%. Credit spreads on corporate bonds and leveraged loans were near the low ends of their historical ranges, while banks reported commercial and industrial lending standards at the easier end of their historical range.

That is not the backdrop for an emergency cut. It is also not the backdrop for a central bank to declare victory on prices. Warsh put the 12-month PCE inflation rate at 3.7% and the six-month rate at 4.1%. Of the 199 individual components in the PCE basket, 54% had risen at an annual rate above 3% over the past year, while 49% were above that threshold on a six-month annualized basis. The readings were well below the post-pandemic peak, but still too broad to make a short burst of softer monthly data decisive.

Warsh's language was intentionally conditional, but it was not soft. The Fed chair said, “We must be confident that underlying inflation is moving to our objective, clearly and at sufficient speed. Otherwise, we have work to do. That's our job, our mandate and our charge to keep.” That sentence did two things at once. It made the inflation standard explicit, and it moved responsibility for the next step back onto the central bank rather than onto Treasury yields, financial conditions or market expectations.

The market had been waiting for exactly that ownership. In the weeks before Jackson Hole, Warsh's insistence that higher bond yields could do some of the Fed's tightening had left investors unsure whether the central bank was prepared to act or merely willing to let the market act for it. Bloomberg reported on Aug. 28 that Warsh's speech eased some of the bond market's concerns about his inflation credibility, while Gregory Daco, chief economist at EY-Parthenon, told the Wall Street Journal the long end now had “a bit more of a firmer anchor” because part of the earlier rise in long-term yields reflected questions around Fed credibility.

The repricing was concentrated where it should have been. Reuters reported that the two-year Treasury yield rose 12.79 basis points to 4.36% on Aug. 28, while the 10-year rose 5.6 basis points to 4.728% and the 30-year rose 2.19 basis points to 5.2129%. The curve's front end did the shouting; the long end barely raised its voice. That is a market saying it believes the Fed may raise rates to address inflation, but it is less worried that the speech itself has created a new long-duration credibility shock.

Chris Gunster, head of fixed income at Fidelis Capital, captured the immediate reaction in Reuters on Aug. 28: “Warsh was more hawkish than expected from the marketplace.” The phrase is more useful than the headline description of the speech as hawkish. It tells us the surprise was not that Warsh cared about inflation. Investors already knew that. The surprise was that he made the inflation commitment legible enough for the rates market to translate it into a higher near-term probability.

A quieter Fed, a louder market

Warsh's communication experiment is the other half of the trade. He argued that forward guidance, which became routine during the Global Financial Crisis, has “overstayed its welcome.” He also warned against a regime in which market participants look primarily to the Fed for their next trade, saying the central bank needs market signals that are as unfiltered as possible. The implication is that investors should track prices, credit availability, commodities and the dollar, then form their own view rather than wait for a policy sentence to do the work.

This is not the same as silence. It is a different kind of information hierarchy. Warsh wants markets to know the 2% target is firm, that short-term rates are the predominant tool and that financial conditions do not currently look restrictive. He does not want them to know a formula that mechanically maps one inflation print into one policy action. The speech therefore reduced uncertainty about the destination while preserving uncertainty about the route.

Phil Blancato, chief market strategist at Osaic, made that distinction in Reuters on Aug. 28: “Warsh was certainly clearer than he was in July,” he said, while adding that the speech gave relatively little guidance on what mix of inflation and labor data would make the Fed act. That is the credibility repair in one sentence. Clarity about the mandate can stabilize the long end even when the reaction function remains incomplete.

Cyrus Amini, chief investment officer at Hyphen Wealth Management, put the bond-market benefit more directly in the same Reuters report: “This should quell some of the bond market anxiety as he gave a clear picture of the Fed's stance on inflation and the need to push it down to target at sufficient speed.” Yet Amini also noted that the speech lacked a credible plan to fight inflation. Investors should take both halves seriously. A central bank can restore its inflation language before it restores its policy credibility. The latter requires data, votes and eventually action.

The dollar and equities offered a similar split verdict. Reuters said the dollar index rose 0.61% to 99.71, while the dollar strengthened 0.45% against the yen to 160.11 and the euro fell 0.61% to $1.158. The S&P 500 initially rose after the speech before ending down 0.2%, according to the Wall Street Journal, while gold fell 3.2%. Those moves suggest the market did not hear a recessionary Fed. It heard a higher discount rate for risk assets, a less urgent need for alternative stores of value and a more conventional reason to own dollars.

But the September hike is not yet a done deal. Reuters' account put the odds near 60%, and CNBC reported a 55.7% probability after the speech, but both figures are market pricing, not a commitment from the FOMC. Only one inflation report was expected before the Sept. 15-16 meeting. A single soft print could still preserve the hold, while a firm report would give Warsh the data he says he needs. The market has priced the option; it has not exercised it.

The distinction matters because Warsh's framework is designed to keep the Fed from being trapped by its own language. If the next inflation report is hot, the chair has already said the central bank has work to do. If it is soft, he can argue that the underlying trend has not yet moved clearly and quickly enough, or he can wait without contradicting the speech. That flexibility may be frustrating for traders, but it is precisely what a quieter Fed is trying to preserve.

Our view is that the most important output from Jackson Hole was not the 60% hike probability. It was the front-end and long-end split. The market now sees a credible chance of a policy move without treating the speech as proof that long-term inflation expectations are unanchored. That is a healthier repricing than the earlier across-the-curve selloff, but it is also a warning that the Fed's credibility remains conditional on follow-through.

Investors should watch the breadth of the next inflation print, not just the headline. A further fall in the share of PCE components above 3% would validate Warsh's emphasis on underlying trend and speed. A renewed rise would turn his carefully worded discipline into a policy test. Until then, the trade is not “Warsh means hike.” It is that Warsh has bought the Fed one more meeting in which the data, rather than the chair's next sentence, can decide.
