On November 13, Chicago Fed President Goolsbee said in an interview with Yahoo Finance that he had initially expected U.S. inflation to cool markedly as the effects of tariffs faded and oil prices fell, but those expectations have yet to materialize. October CPI rose more than expected, marking a second consecutive month of acceleration. Goolsbee warned that the United States has reached a "dangerous moment" for inflation and that policymakers must remain prudent to prevent further deterioration. He noted that persistent price pressures remain in CPI categories such as services and health care—areas unrelated to tariffs and oil prices—and that the United States is gradually entering a phase in which central banks historically find it difficult to contain inflation. Goolsbee said the Fed is trying to distinguish between two types of factors driving persistently high inflation: first, supply-side shocks such as tariffs and elevated oil prices lasting longer than expected; and second, demand-side overheating caused by large-scale data center construction. He noted that AI-related inflation has not yet spread to the broader economy and is currently concentrated mainly in AI, technology, and related industries, but the Fed is closely monitoring whether it spills over into other areas. If demand overheating triggered by data center construction begins to affect the broader economy, it will become a problem, he said. He also mentioned that recently elected Democratic governors have proposed pausing data center construction—a development that currently has no direct connection to the Fed's inflation work.
