Following Federal Reserve Chair Kevin Warsh‘s hawkish Jackson Hole address, Wall Street analysts are sharply divided on the likelihood of a September rate hike. Veteran investor Louis Navellier advises market watchers to relax, while LPL Financial Chief Economist Jeffrey Roach argues that resilient economic data and sticky prices justify further tightening.

Navellier’s Call for Calm

The founder of Navellier & Associates is aggressively pushing back against the prospect of an immediate rate hike. Navellier exclusively told Benzinga that the central bank’s preferred inflation gauge, the Personal Consumption Expenditures (PCE) index, is “irrelevant” because the Fed cannot control inelastic food and energy inflation.

Furthermore, Navellier emphasized that Warsh is restructuring the central bank through five new task forces. Because these task forces have not yet completed their reports, Navellier stated he would be “shocked” if the Fed hiked key interest rates in September.

“Fed watchers should take a ‘chill pill’ and let Warsh continue to remake the Fed from the bottom up,” he noted.

Roach Warns of Sticky Prices

Conversely, Roach sees a strong case for continued hawkishness unless upcoming labor data takes a decidedly weaker turn.

Also in an exclusive comment to Benzinga, Roach cautioned that “the economic data are currently quite healthy while services inflation is stubbornly elevated and that combination warrants further tightening.”

He also noted that while AI capital expenditures are booming, the consumer still makes up roughly 70% of the economy, meaning the Fed must remain highly focused on persistent consumer price pressures.

The Broadening Inflation Trail

Roach’s concerns echo the exact data points Warsh highlighted at Jackson Hole. During his speech, Warsh explicitly pointed out that over the past 12 months, 54% of goods and services in the PCE basket showed price increases above 3%.

This broadening inflation was also flagged by Ryan Detrick, who noted in a post on X that 54% of core PCE components rose above 3% year-over-year in July 2026, up from 47% in July 2025.

Hike Expectations and Market Performance

The CME Group’s FedWatch tool projections show markets pricing in a 66.4% likelihood of the Federal Reserve hiking interest rates at its September meeting. Meanwhile, traders on Polymarket pushed the odds of a September 2026 rate hike to 55%.

The S&P 500 index has advanced 12.07%% YTD. Similarly, the Nasdaq Composite index was up 13.49%, and the Dow Jones gained 9.93% YTD.

On Monday, the SPDR S&P 500 ETF Trust (NYSE:SPY) and Invesco QQQ Trust ETF (NASDAQ:QQQ), which track the S&P 500 and Nasdaq-100, respectively, closed mixed. The SPY was down 0.30% to $767.05, while the QQQ advanced by 0.046% to $716.76. Meanwhile, the Dow tracker, State Street SPDR Dow Jones Industrial Average ETF Trust (NYSE:DIA), ended 0.65% lower at $531.57.
