What It Measures

Capacity Utilization measures what percentage of the economy's total productive capacity is currently being used. It is calculated as:

Capacity Utilization = (Actual Output / Potential Output) × 100
    The measure covers the same sectors as Industrial Production:
  • Manufacturing (factories)
  • Mining (oil, gas, minerals)
  • Electric and gas utilities

A reading of 80% means the industrial sector is operating at 80% of its maximum sustainable output.

Why It Matters

Inflation Predictor: High capacity utilization (above 80%) suggests potential inflationary pressure as businesses have less room to expand and may raise prices.Investment Signal: Low utilization discourages new capital investment; high utilization encourages it.Fed Watch: The Federal Reserve monitors capacity utilization as an indicator of economic slack and potential inflation.Recession Indicator: Sharp declines in utilization often accompany or precede recessions.

How to Interpret

Above 80%: Economy running hot, potential inflation pressure, capacity constraints 75-80%: Healthy utilization, room for growth without inflation 70-75%: Moderate slack in the economy Below 70%: Significant excess capacity, deflationary pressure, recession risk

Watch for sustained trends rather than single-month readings, as the data can be volatile.

Key Levels to Watch

LevelInterpretation
Above 82%Potential inflation pressure, capacity constraints
78-82%Healthy utilization with room for growth
75-78%Some slack in the economy
70-75%Significant unused capacity
Below 70%Severe recession levels, major excess capacity

Historical Context

Capacity utilization averaged around 80% from the 1970s through 2000s. It plunged to 66.7% during the 2009 recession and 64.2% during the COVID-19 pandemic (April 2020), both representing severe underutilization of productive capacity.

Limitations

    Capacity utilization has some limitations:
  • "Capacity" is estimated and can be revised
  • Does not capture service sector utilization
  • May lag actual economic conditions
  • Technological changes can affect potential capacity estimates
