The United States economy demonstrated a more robust performance than anticipated in the third quarter, expanding at an annualized rate of 3.4% between July and September, according to a government report released Thursday. This represents a significant acceleration from the 2.2% annualized GDP growth recorded in the second quarter and outpaced the 2.5% rate seen in the first three months of the year.

Despite concerns over rising prices and their impact on consumer finances, the economy has shown resilience. Hiring has continued to grow, albeit at a slower pace, while the unemployment rate remains historically low. A notable contributor to this growth has been increased spending on artificial intelligence, with many major companies investing heavily in the necessary AI infrastructure such as chips and data centers.

Federal Reserve Chair Kevin Warsh acknowledged the positive economic momentum, stating that "Economic activity is expanding at a strong pace. While uncertainty remains, owing in part to geopolitical developments, domestic spending has been resilient." However, he also noted the ongoing challenge of elevated inflation.

Inflationary pressures have prompted action from the Federal Reserve, which raised interest rates by a quarter of a percentage point last month in an effort to curb rising prices. This marked the first rate increase in three years. On Wednesday, the central bank opted to hold rates steady as they assess further economic data. Inflation stood at 3.7% in September compared to the previous year, exceeding the Fed's target of 2%.

Market sentiment, as indicated by CME Group's FedWatch Tool, suggests an approximately 85% probability of another quarter-point rate hike at the Fed's December meeting. Such an increase would signal a more aggressive stance by the central bank to combat inflation, potentially leading to slower economic growth and a further cooling of the job market. Warsh reiterated the Fed's commitment to reducing inflation, stating, "It's our responsibility to get inflation down."
