Historical data reveals that, barring a major policy pivot, the Jackson Hole symposium rarely serves as a powerful catalyst for US equities. Options pricing currently implies an expected move of just 0.6% in the index on the day of Warsh's speech. Such market calm, however, is precisely a reason for caution.
Wall Street is gearing up for Federal Reserve Chair Kevin Warsh's inaugural address at the Jackson Hole Economic Symposium on Friday, but history suggests this closely watched speech may not trigger dramatic swings in US stocks. According to data compiled by Bloomberg, since 2000, the S&P 500 has averaged a gain of only 0.4% in the week following the Jackson Hole meeting. Unless the Fed Chair's remarks coincide with a major impending shift in monetary policy, this annual central bank gathering typically is not a significant catalyst for the equity market.
The options market is likewise not pricing in a big move. Daniel Kirsch, head of options at Piper Sandler, noted that current market pricing implies the S&P 500 will fluctuate by only about 0.6% on the day of Warsh's speech. However, Warsh differs from his predecessors in that he has consistently avoided providing clear forward guidance on the path of future interest rates, which could paradoxically increase the scope for the market to interpret his remarks on its own.
Kevin Flanagan, head of investment and fixed income strategy at WisdomTree, stated that the market currently does not expect Warsh to suddenly change his policy stance, so the "threshold" for triggering volatility is low. Yet, the lack of forward guidance also means Wall Street could misread his intentions.
The crux: Will Warsh reveal his policy logic?
Warsh is scheduled to speak at 10:00 PM Beijing time on Friday. With two key economic data releases still ahead before the Fed's September meeting—the September 4th jobs report and the September 11th consumer price data—he may not be in a hurry to discuss the timing of a September rate hike. Economists led by Jan Hatzius at Goldman Sachs anticipate that Warsh will acknowledge recent improvements in inflation data but will refrain from offering specific policy guidance. Goldman Sachs forecasts the Fed will hold rates steady at its September meeting and for the remainder of the year, with the better inflation prints from June and July strengthening the case for the majority, especially voting members, to remain on hold.
Currently, swaps market pricing indicates only about a one-third probability of a rate hike in September. Therefore, if Warsh unexpectedly signals a more hawkish stance, the market could still see volatility. Flanagan believes Warsh's first Jackson Hole speech is itself a learning process. What the market truly wants to know is: how does he currently, and will he in the future, view the US economy and inflation?
This kind of uncertainty is not without precedent. In 2022, then-Fed Chair Jerome Powell delivered a hawkish speech at Jackson Hole, explicitly warning that combating inflation would bring "pain" to households and businesses. On that day, the S&P 500 plunged 3.4%, the US 10-year Treasury yield swung by 8 basis points intraday, and markets continued to raise their expectations for Fed rate hikes in the weeks that followed.
The calmer US stocks are, the more one should be wary of surprises.
The current market is clearly not trading along the 2022 script. After rebounding from earlier global growth concerns and the shock of conflict with Iran, the S&P 500's market capitalization has recovered by nearly $12 trillion, with large-cap tech stocks once again becoming the core of capital flows. As of now, the S&P 500 sits less than 1% below its record closing high and has not experienced a single-day decline of 1% for 21 consecutive trading days. Meanwhile, the Cboe Volatility Index (VIX) has dropped below 15, roughly 20% lower than its average over the past year, indicating that investors are not worried about policy shocks emanating from Jackson Hole.
Jed Ellerbroek, portfolio manager at Argent Capital Management, believes that Warsh's core stance is to avoid forward-looking commentary on future monetary policy, so he will likely not deviate from that approach in his speech. With the impact of tariffs on inflation fading and oil price pressures from the Middle East conflict easing somewhat, Warsh's remarks may offer only limited reference value for traders.
However, strategists led by Michael Hartnett at Bank of America present an alternative scenario: if Warsh can simultaneously reinforce his anti-inflation credibility and signal support for Treasury Secretary Scott Bessent's efforts to control long-term financing costs, it could flatten the US yield curve and boost risk appetite and the dollar. Conversely, if Warsh's comments are perceived by the market as a "policy misstep," long-term Treasury yields could rise back to levels seen before Bessent announced the expanded long-dated Treasury buyback program, pressuring the dollar and prompting capital to rotate into defensive stocks rather than cyclical names sensitive to long-term rates.
For US equities at current elevated levels, this means the real issue is not necessarily how much of a market move Warsh will trigger, but whether he might unexpectedly alter the market's assessment of inflation, interest rates, and long-term Treasuries at a time when investor vigilance is generally low and volatility remains subdued. BofA also noted that in the week ending August 26, US equity funds saw outflows of $4.4 billion, the first net outflow after five consecutive weeks of inflows; during the same period, funds rotated toward Japanese stocks, while investment-grade bonds saw inflows for the 21st consecutive week.
