US inflation rises to 3.7% in September; AI infrastructure stocks decline

United States consumer prices increased in September, marking the final inflation report before the midterm elections. The Consumer Price Index (CPI) report released by the Labor Department’s Bureau of Labor Statistics (BLS) on Wednesday showed that annual inflation accelerated to 3.7 percent, up from 3.4 percent in August. On a monthly basis, prices rose by 0.6 percent.

Inflation Drivers and Market Reaction

Petrol prices were the primary driver of the monthly increase, rising 9.1 percent in September. According to the BLS, this accounted for more than half of the CPI monthly increase. Petrol prices were up 34.2 percent from the same time a year ago. Kyle Moore, chief economist at The Century Foundation, stated, “The directionless war in Iran continues to disrupt global supply chains, driving up the prices of food and fuel.”

Following the release of the data, US markets trended downward. The Nasdaq fell 0.8 percent and the S&P 500 dropped 0.6 percent, while the Dow Jones Industrial Average was roughly flat in midday trading. Separately, CNBC reported that AI infrastructure stocks tumbled, though the provided excerpt did not explicitly detail the specific reaction of these stocks to the CPI data or confirm the inflation report as the sole trigger for their decline.

AI Infrastructure Costs

The inflation report highlighted significant price increases in sectors related to artificial intelligence. Amid heavy investment in AI infrastructure, prices for computer software and accessories jumped 28 percent from the same time last year. Rami Cassis, principal of Parabellum Investment, noted the impact of this sector on inflation. “The AI boom is playing a huge part, and we have all read about the hundreds of billions being poured into data centers, AI firms, and models,” Cassis said in comments provided to Al Jazeera.

Federal Reserve Outlook

The inflation data comes days before the US Federal Reserve’s interest rate decision later this month. Last month, the central bank raised rates by 25 basis points, bringing the target range to 3.75–4.00 percent, the first hike in three years. Economists remain divided on the next move. According to CME FedWatch, there is a 52.9 percent chance that rates will remain in the 3.75–4.00 percent range, while there is a 47.1 percent chance of a quarter of a percentage point hike that would bring them to 4.00–4.25 percent.

Why it matters

The rise in inflation to 3.7 percent complicates the Federal Reserve's decision on interest rates just weeks before the midterm elections. While general market indices declined, the specific performance of AI infrastructure stocks remains a point of interest for investors, particularly given the 28 percent year-over-year increase in software and accessory prices linked to AI investment. The uncertainty surrounding future rate hikes continues to influence market volatility.
