Wall Street Week Ahead-Investors brace for possible rate hike at uncertain Fed meeting

As investors prepare for the upcoming Federal Reserve meeting, they are anticipating a potential interest rate hike, which could impact a stock market already showing signs of vulnerability due to rising bond yields. Inflation has consistently remained above the Fed's 2% annual target, leading to interest rate increases as the primary tool to control prices. Following last month's hawkish remarks by new Fed Chair Kevin Warsh, bets have grown that the Fed will raise rates on Wednesday during the meeting.

Data released on Friday showed a hotter-than-expected increase in consumer inflation for August, with the core measure of the Consumer Price Index rising by 0.3%. Chief investment officer at BNY Wealth, Alicia Levine, expects a quarter percentage point hike from the Fed. Higher interest rates could negatively affect stock performance by raising borrowing costs for consumers and companies, as well as creating more competition for investments from bonds.

The S&P 500 has gained nearly 12% so far in 2026, driven by strong corporate earnings growth fueled by significant spending on AI infrastructure. However, the index has recently pulled back and is now around 2% below its mid-August high. Bond market selling has pushed U.S. Treasury yields to multiyear highs, nearing a 5% level that could cause further troubles for stocks. Tensions between the U.S. and Iran have also spooked investors, pushing oil prices above $100 a barrel.

Market odds currently lean towards a quarter-point hike. Recent Fed funds futures indicated an over 80% chance of a rate increase by the Fed, which has fluctuated in recent weeks as traders reacted to economic data and Fed officials' comments. Strong job gains in the latest employment report have bolstered the likelihood of a rate hike, while the latest core Personal Consumption Expenditures Price Index reading showed inflation at 3.3% on an annual basis.

If the Fed hikes rates on Wednesday, investors will closely monitor signs of whether it will be an isolated move or the beginning of a series. If it signals a cycle, it may not be favorable for the market. Some investors believe the Fed decision will serve as a test of Warsh's credibility in fighting inflation, which came under scrutiny after his press conference in July.

Citi Wealth's head of portfolio strategy, JP Coviello, noted that the market remains concerned about Fed independence. While rate hikes and higher yields could impact bond yields and equities, the strong earnings performance of companies may outweigh the rise in real yields from an equity investment perspective.
