Federal Reserve Chair Kevin Warsh is set to deliver his inaugural keynote address at the global central bank symposium in Jackson Hole, Wyoming, on August 28th. This is far more than a routine speech at an annual policy gathering—Wall Street views it as the pivotal moment for Warsh to re-establish the Fed's credibility.

Since taking office in May, Warsh has championed a "quieter Fed" philosophy, deliberately avoiding forward guidance, shortening policy statements, and remaining vague during two press conferences. Markets have interpreted this as a lack of resolve to combat inflation, sending long-term Treasury yields soaring to two-decade highs. With 30-year yields briefly touching 5.34%—the highest since 2007—the national debt surpassing $40 trillion, and inflation exceeding the 2% target for five consecutive years, Warsh's silence is becoming an expensive noise.

As the world's largest AI chip maker Nvidia prepares to report earnings this Wednesday, Wall Street is sounding an alarming note: the Jackson Hole risk is greater than Nvidia's earnings report. Ann Milletti, an executive at Allspring Global Investments, bluntly states that Nvidia's results represent a "single earnings anchor," while Warsh's speech is a "systemic pricing anchor" that could simultaneously alter rate expectations, term premiums, dollar liquidity, and discount rates for global risk assets.

Warsh's "Silence Philosophy": Markets Penalizing Uncertainty with Higher Yields

Warsh's communication strategy since taking office has been described by former St. Louis Fed President Bullard as the Fed's "most significant shift in decades." He has abandoned the forward guidance tradition that lasted over a decade, arguing it "reduces policy flexibility and disrupts market signals." However, markets are not buying it.

Following the July FOMC meeting, Warsh neither delved into economic conditions nor hinted at the rate path. Investors interpreted this as a lack of determination to bring inflation back to target, pushing long-term bond yields to two-decade highs. Former Philadelphia Fed President Plosser directly stated: "Warsh must confront the elephant in the room—inflation. He must say more than 'we are working on it.' That kind of statement is no longer sufficient; markets will be deeply disappointed."

Bullard's warning is even sharper: "The Fed's credibility is at risk—markets are beginning to believe the committee doesn't truly care about bringing inflation down to 2%." He specifically noted that Warsh has yet to clearly signal willingness to raise rates to achieve the 2% inflation goal, and this silence itself has become a source of market doubt.

Goldman Sachs Chief Economist Hatzius warns from a market volatility perspective: Warsh's ambiguous communication style will make "market fluctuations around the Fed's future rate decisions more volatile," and such volatility "will not have any constructive effect on the economy." Goldman calculates that enhanced communication could reduce rate volatility by about 10% over the next year—Warsh is moving in the opposite direction.

TD Securities US rate strategist Molly Brooks warns of a clear "asymmetric risk" at Jackson Hole—if Warsh provides too little information, markets are likely to be disappointed, and even if he offers some explanation of his reaction function, the upside is limited because markets don't expect sufficient detail from him.

Bond Market "Out of Control": 2007 Levels Revisited

On August 18th, the US 30-year Treasury yield briefly touched 5.334% during trading, the highest level since June 2007—just before the global financial crisis. The 10-year yield simultaneously rose to 4.75%, the highest since January 2025. This is not unique to the US—Germany's 10-year yield surged to 3.261%, the highest since 2011, and France's 10-year yield broke above 4% for the first time since 2009.

Behind this global bond selloff are three structural forces converging: US-Iran conflicts repeatedly fueling inflation concerns, the flood of AI corporate bonds competing with government debt for investors, and the US fiscal deficit surpassing $1.8 trillion. Treasury Department data from August 19th shows the cumulative fiscal deficit for the first ten months of FY2026 has reached $1.799 trillion, already exceeding the full-year FY2025 total with two months remaining in the fiscal year.

Kathy Bostjancic, Chief Economist at Nationwide Mutual Insurance Company, says the pressures on markets persist, including fiscal concerns, inflation, and uncertainty about how the Fed will respond. "The fundamental causes of rising long-term rates remain," she says.

Facing the emergency of 30-year yields breaking above 5.33%, Treasury Secretary Bessent intervened on August 19th, raising the single-operation cap for liquidity support repurchases of 10- to 30-year long-term bonds from $2 billion to at least $4 billion. However, this "fever reducer" lasted less than 24 hours—on August 20th, the 30-year yield rose another 5.7 basis points to 5.251%. The outstanding stock of 20-year and 30-year Treasuries is approximately $5.5 trillion, and the additional $2 billion per operation is a drop in the bucket relative to the tens of trillions total.

PCE Data: The "Preliminary Skirmish" Before Jackson Hole

Before Warsh's speech, markets will receive the Fed's preferred inflation gauge on Wednesday, August 26th—the July Personal Consumption Expenditures (PCE) price index. Economists expect headline PCE to rise 3.6% year-over-year in July, a slight moderation from June's 3.7%, with core PCE expected to remain around 3.3%—still well above the Fed's 2% target.

Bloomberg Economics notes that despite signs of cooling inflation, oil prices have risen again this month, with the ongoing Iran conflict pushing energy costs higher. If PCE data comes in above expectations, it would further strengthen the case for a September rate hike—CME FedWatch currently shows a September hike probability of about 41%, with one hike expected by year-end. If data comes in below expectations, it could provide more room for Warsh's "wait-and-see" strategy. But regardless of the outcome, the fact that inflation has exceeded target for five consecutive years has put the Fed's credibility under unprecedented scrutiny.

Former St. Louis Fed President Bullard stated directly: "The Fed's credibility is at risk—markets are beginning to believe the committee doesn't truly care about bringing inflation down to 2%."

Three Possible Scenarios for Jackson Hole

Warsh has not yet decided whether to discuss the macroeconomic "big picture" or directly provide guidance on the September-to-December policy path. Bloomberg Economics expects Warsh is more likely to choose the latter—"doubling down on his reform agenda to reduce forward guidance"—focusing on describing the "intellectual framework" of Fed reform rather than giving specific policy signals.

Dhiraj Narula, rates strategist at HSBC, says this provides Warsh with an opportunity to reassure investors by clarifying his outlook. Narula states: "We believe Chairman Warsh's views on underlying inflationary pressures may already provide some justification for reducing the uncertainty-related term premium."

However, TD Securities expects Warsh "will not change his usual approach to discussing the economic outlook," and markets will be "looking for clues about his policy reaction mechanism and whether he will reconfirm the Fed's determination to fight inflation." Evercore ISI senior economist Casiraghi warns that merely repeating the highly committed language about "restoring price stability" from the June and July press conferences "may no longer be sufficient."

Three Scenarios and Their Potential Directions

Scenario One: The Ambiguous Path (highest probability). Warsh reaffirms his commitment to price stability but refuses to give a specific path. Markets will treat the three dissenting votes at the September FOMC as the "only actionable signal." The 30-year Treasury yield could break above 5.4%, the dollar faces pressure, and gold continues to rise.

Scenario Two: Hawkish Signal. Warsh clearly indicates willingness to raise rates to combat inflation, and September hike probability rebounds significantly from the current ~32%. Long-term bond yields briefly pull back (as markets regain confidence in the Fed's resolve), but the dollar strengthens and risk assets come under pressure.

Scenario Three: Dovish Turn. Warsh hints that the threshold for rate hikes is very high, and markets price in no further hikes this year. Long-term yields fall on expectations of a "Warsh put option," the dollar weakens, and risk assets rebound—but this would further deplete his anti-inflation credibility.
