New economic data suggests the US economy may be expanding more rapidly than Federal Reserve Chairman Kevin Warsh has acknowledged. While the central bank recently opted to hold interest rates steady, rising price pressures and surging business investment are creating a complex environment for policymakers.

What does the recent growth data show?

The US Commerce Department reported that third-quarter gross domestic product grew at a 3.4% annualized rate between July and September. This growth exceeded previous expectations and was driven by several key factors:

  • Consumer spending increased by 3.8%.
  • Business equipment investment surged by 20.9%.
  • Growth has been bolstered by significant investments in artificial intelligence.

Despite this momentum, some analysts worry about sustainability. Consumer spending is currently outpacing income growth, a trend that economists suggest may not be permanent.

Is inflation becoming more widespread?

Recent figures for the Personal Consumption Expenditures (PCE) Price Index, the primary gauge used by the Fed to track its 2% inflation target, indicate persistent price increases. In September, the index rose 3.6%, up from 3.4% the previous month.

Data shows that between 50% and 60% of items in the PCE index saw annual price hikes exceeding 3% in September. This breadth of inflation is significantly higher than pre-pandemic norms. Diane Swonk, chief economist at KPMG, noted that inflation appears broadly persistent, particularly within the service industries.

Why does this matter for interest rates?

Chairman Warsh has expressed a desire not "to throw sand in the gears" of the current economic expansion. However, the combination of strong demand and broad-based inflation may eventually force the Federal Reserve to reconsider its stance on monetary policy. While the Fed has remained patient to avoid triggering a recession, the disconnect between rapid growth and inflation targets remains a primary concern for the stability of the US economy over the long term.
