Fed Rate Hike Expectations Rise as AI Sector Splits

Markets brace for a Federal Reserve rate hike as oil prices climb and AI stocks diverge sharply.

U.S. equity futures traded mixed late Monday as investors priced in a 92.4% probability of a quarter-point interest rate hike at the upcoming Federal Reserve meeting. This significant shift in expectations, driven by persistent inflation concerns and rising energy costs, contrasts with the 59.4% likelihood recorded just one week prior. The market reaction reflects a growing consensus that the central bank will tighten monetary policy to counteract economic pressures.

Simultaneously, the technology sector experienced a pronounced divergence between chipmakers and software providers. Leading semiconductor stocks posted steep declines, while enterprise software firms surged, marking the largest relative performance gap between these two groups in 25 years. This rotation was triggered by industry leaders publicly debating the pace and safety of artificial intelligence development.

AI Industry Split Drives Sector Rotation

Disagreement among top executives regarding AI safety and development speed reshaped investor sentiment. Anthropic CEO Dario Amodei proposed slowing the pace of AI advancement, a stance supported by OpenAI CEO Sam Altman and SpaceX CEO Elon Musk. Conversely, Microsoft and Meta Platforms leadership opposed any deceleration. This split caused immediate reallocation of capital away from hardware manufacturers and toward software companies perceived as less exposed to rapid hardware obsolescence.

Nvidia Corp. shares dropped more than 3%, while Micron Technologies fell over 5% on Monday. The iShares Semiconductor ETF (SOXX) lost more than 5% of its value. In contrast, Salesforce Inc. gained over 4%, and security-focused firms Palo Alto Networks Inc. and CrowdStrike Holdings Inc. each rose more than 13%. The iShares Expanded Tech-Software Sector ETF (IGV) climbed approximately 5%, indicating a strong shift toward established software businesses.

Oil Prices And Bond Yields Climb

Rising crude oil prices exacerbated inflationary pressures, supporting the case for aggressive monetary tightening. Brent crude futures for November delivery rose more than 1% to $106.95 per barrel, while WTI crude futures for October increased 1.30% to $102.71 per barrel. These increases are attributed to ongoing geopolitical tensions in the Middle East, which continue to disrupt supply chains and keep energy costs elevated.

Long-term bond yields also increased despite the U.S. Treasury's announcement last week that it would triple its debt buyback plan to $6 billion. The 10-year Treasury yield traded at 4.998%, briefly surpassing the 5% mark during the session, while the 30-year yield reached 5.359%. Higher yields increase borrowing costs for corporations and consumers, creating a challenging macroeconomic backdrop for equity valuations.

Market Closes Reflect Broad Caution

At the close of Monday's trading, all three major U.S. benchmarks finished lower. The Nasdaq Composite led the decline, dropping more than 146 points to close 0.56% lower at 26,186.41. The S&P 500 lost 0.48% to end at 7,619.98, while the Dow Jones Industrial Average slipped 0.29% to 52,421.20. According to GN stocks/sp500 data, this performance underscores investor caution ahead of the Federal Reserve's decision and amid uncertainty in the AI sector.
