Investors brace for possible rate hike at uncertain Fed meeting

Market participants anticipate the Federal Reserve could raise interest rates during their upcoming meeting, a prospect that may challenge the existing U.S. stock market rally. Inflation has remained stubbornly high, exceeding the Fed's 2% target, and rate hikes are typically employed to curb price growth. Following Kevin Warsh's recent hawkish speech, speculation has intensified that the Fed will hike rates by a quarter percentage point on Wednesday, marking the conclusion of their two-day meeting.

Some investors remain skeptical, however, and data revealed in August that consumer inflation surged by 0.3%, which helped to tip the scales in favor of a rate increase.

Higher interest rates could adversely affect stocks in several ways, such as increasing borrowing costs for consumers and companies while simultaneously pressuring equity valuations through more competition from bonds. The S&P 500 has risen nearly 12% this year, propelled by strong corporate earnings growth driven by significant investments in AI infrastructure.

Despite the rally, the index has recently declined and is now nearly 2% below its mid-August peak. Additionally, escalating tensions between the U.S. and Iran have driven oil prices above $100 a barrel, further adding to market uncertainty.

Fed funds futures indicate a more than 80% likelihood that the central bank will raise rates by a quarter percentage point, with odds fluctuating over time in response to economic data and Fed officials' statements. Strong job growth reported in the latest employment report bolsters the chances of a rate hike, as does the core Personal Consumption Expenditures Price Index, which came in at 3.3% on an annual basis last month.

Despite persistent inflation and a low unemployment rate, the Fed's decision to hike rates could still be viewed as either a one-off move or the beginning of a series. If the Fed hikes, investors will scrutinize whether it signals a broader cycle of rate hikes or a stand-alone decision.
