US manufacturing activity reaches four-year high driven by AI

United States manufacturing activity reached its highest level in over four years in July, according to data from the Institute for Supply Management. The Manufacturing Purchasing Managers' Index (PMI) rose to 55.6, surpassing the June figure of 53.3 and exceeding economist projections of 54.

Growth was observed across fifteen manufacturing industries, including machinery, transportation equipment, primary metals, and electrical equipment. A significant driver of this expansion is the artificial intelligence buildout, specifically the surging demand for power equipment and infrastructure required for AI data centers.

Major corporations are pivoting to capitalize on this trend. Caterpillar has identified its power-generation business as a highly profitable segment, investing $725 million to expand generator production in Indiana and repurposing a Kansas facility for turbine engines. Similarly, Ford Motor is establishing a Ford Energy subsidiary, with plans to spend $2 billion redirecting battery capacity toward electricity storage for data centers and industrial users. Other companies, including Cummins, Eaton, and Vertiv, are also adjusting operations to meet this demand.

Despite the strong activity, some survey respondents expressed concerns regarding price volatility and geopolitical tensions. Additionally, some economists suggest that the robust growth could influence the Federal Reserve's decisions regarding interest rates.
