U.S. stocks reversed earlier gains on Wednesday and moved lower after Federal Reserve Chair Kevin Warsh warned that inflation remains too high.
The market had initially reacted positively to the Federal Reserve’s first interest rate hike since 2023. However, sentiment changed during Warsh’s press conference as investors focused on the possibility of further tightening.
The S&P 500 fell 0.7% to 7,532.29 points after rising as much as 0.5% earlier in the session. The Nasdaq Composite slipped 0.2% to 25,909.27 after gaining as much as 0.9%.
Meanwhile, the Dow Jones Industrial Average dropped 1.5% to 51,292.18 points. Earlier in the day, the index had been up as much as 0.2%.
Warsh Warns That Inflation Remains Too High
The Federal Open Market Committee unanimously voted to raise the federal funds rate to a range of 3.75%-4.00%, up from 3.50%-3.75%.
At the same time, the Federal Reserve’s latest Summary of Economic Projections showed a median federal funds rate of 4.1% at the end of 2026. That implies policymakers currently expect at least one additional rate hike.
Expectations for tighter monetary policy had already been increasing ahead of Wednesday’s decision.
Recent U.S. economic data pointed to resilient growth, a strong labor market, and persistent inflation pressure.
The personal consumption expenditures price index, the Fed’s preferred inflation gauge, increased 3.7% year over year. That remains well above the central bank’s long-term 2% target.
PCE inflation has now remained above the 2% level for 65 consecutive months.
“The plain fact is that inflation is too high and has been for too long,” Warsh told reporters following the decision.
Fed Signals That More Rate Hikes Could Follow
Warsh said the latest policy move reflected a strengthening U.S. economy, stubborn inflation during the summer, and geopolitical risks.
He also said Federal Reserve officials agreed that broader financial conditions were not restrictive enough.
However, Warsh again avoided giving clear forward guidance on the future path of interest rates. He also did not provide his own projection in the Fed’s updated dot plot.
Peter Tuz, president of Chase Investment Counsel, said markets received the widely expected 25-basis-point increase but also heard a clear message that additional hikes could follow.
Tuz added that Warsh appeared determined to bring inflation back toward the Fed’s 2% target and viewed current inflation levels as damaging to consumers.
Fed Dot Plot Turns More Hawkish
Investors also focused on the more hawkish signals contained in the Federal Reserve’s updated economic projections.
At least 12 FOMC participants now expect one more rate hike this year. Four officials projected two additional hikes, while two expect no further increases.
Another notable change was the Fed’s inflation outlook.
The median forecast for core PCE inflation to return to the 2% target was pushed back to 2029 from 2028.
Tuz said the change was somewhat surprising because it suggested the current tightening cycle could last longer than many investors had previously expected.
Treasury Yields Rise as Bond Sell-Off Resumes
The U.S. bond market has also played a major role in shaping expectations for higher interest rates.
Longer-term Treasury bonds have faced heavy selling pressure since around the Fed’s July meeting. That has pushed yields to their highest levels in years.
The sell-off began after three regional Fed presidents opposed the July decision to keep rates unchanged and instead supported a rate increase.
Selling pressure then intensified in August amid higher oil prices, concerns over massive spending on artificial intelligence infrastructure, and rising U.S. government debt.
On Tuesday, the U.S. 10-year Treasury yield reached its highest level since April 2007.
The 30-year Treasury yield also climbed to its highest level in more than 24 years.
Bonds initially rebounded on Wednesday ahead of the Federal Reserve decision. However, that rally later faded, sending yields higher once again.
The 10-year Treasury yield rose about 1.6 basis points to 5.012%.
Oil Prices Pull Back After Recent Surge
Oil prices declined on Wednesday after a strong run earlier in the week.
Brent crude futures fell 3.2% to around $105.26 per barrel, while U.S. West Texas Intermediate crude dropped 3.7% to approximately $101.89.
The decline followed signs that concerns over near-term supply disruptions may be easing.
Reuters reported that Saudi Arabia was offering additional crude shipments to Asian refiners through ship-to-ship transfers near Oman’s Sohar port.
Oil prices also faced pressure after the American Petroleum Institute reported an unexpected increase in U.S. crude inventories.
Investors were awaiting official inventory data later in the day.
Middle East Conflict Keeps Energy Markets Volatile
Oil supply risks remain a major concern as tensions across the Middle East continue to affect energy markets.
Saudi Arabia’s East-West Pipeline was damaged by drone attacks from Iran-backed Houthis last week.
The attacks came as tensions between Saudi Arabia and the Houthis intensified, raising concerns over important shipping routes in the region.
The Bab el-Mandeb Strait remains particularly important because it is a major route for global energy shipments.
Bloomberg reported on Wednesday that Saudi Arabia was seeking to restart the damaged pipeline at roughly half capacity within days.
Oil prices had surged on Tuesday following reports that Saudi Arabia suspended loadings at its Yanbu port.
Separate reports that Libya had halted production at three oilfields added further pressure to global supply expectations.
Intel Rises on Potential SK Hynix Partnership
Among individual U.S. stocks, Intel rose about 3.3% after Reuters reported that SK Hynix was discussing the possibility of producing chips with Intel in the United States.
However, SK Hynix later said that no final plans had been confirmed.
The broader technology sector remains under scrutiny amid growing debate over artificial intelligence safety and the pace of AI development.
AI Safety Debate Puts Tech Stocks in Focus
Concerns surrounding artificial intelligence intensified after Anthropic researcher Jacob Coxon resigned and criticized the industry’s approach to AI safety.
Anthropic scientist Evan Hubinger later expressed support for some of Coxon’s concerns.
Anthropic CEO Dario Amodei also called for a slower pace of AI development in a lengthy blog post.
He cited concerns surrounding increasingly capable AI systems and recent cases involving autonomous cybersecurity activity.
Other prominent technology executives, including Sam Altman, Elon Musk, and Demis Hassabis, have also participated in the wider debate over AI safety and regulation.
The issue matters for Wall Street because enthusiasm around artificial intelligence has been one of the main drivers of U.S. equity valuations since late 2022.
Major technology companies have gained trillions of dollars in market value as investors priced in rapid AI adoption and future earnings growth.
Any meaningful slowdown in AI development could therefore become an important risk factor for the technology sector and the broader stock market.
J.B. Hunt Falls on Weaker Earnings Outlook
Elsewhere, J.B. Hunt Transport Services dropped around 12.8%, making it one of the biggest percentage losers in the S&P 500.
The company’s finance chief said at an industry conference that current-quarter earnings could decline between 5% and 10% sequentially.
Higher diesel fuel costs were cited as one of the main reasons for the weaker outlook.
The decline added to broader pressure on Wall Street as investors assessed higher interest rates, persistent inflation, rising Treasury yields, volatile oil prices, and uncertainty surrounding the technology sector.
