What Is the Coincident Economic Index?

The Coincident Economic Index, or CEI, is a composite measure designed to move with the current state of the economy. The Conference Board publishes a U.S. CEI as part of its business-cycle indicator system.

Unlike a leading index, which is meant to turn before the economy, a coincident index is meant to track activity as it is happening. It helps readers judge whether the economy is expanding or contracting now.

Key Takeaways

  • The CEI is designed to move with current economic activity.
  • It is a composite index, not a single data point.
  • The U.S. CEI includes indicators tied to employment, income, production, and sales.
  • It is often read alongside leading and lagging indexes.
  • The CEI can help confirm the current business-cycle backdrop.

What the CEI Measures

The U.S. CEI is built from indicators that tend to rise and fall with aggregate economic activity. These include measures such as payroll employment, real personal income less transfer payments, industrial production, and real manufacturing and trade sales.

Each component captures a different part of the economy. Employment reflects labor demand. Income reflects household earning power. Industrial production reflects output. Sales reflect demand flowing through manufacturing and trade channels.

CEI Compared With Other Timing Indicators

Index type

Timing role

Leading index

Designed to signal future turning points.

Coincident index

Designed to track current economic conditions.

Lagging index

Designed to confirm changes after they occur.

Single indicator

Shows one slice of the economy rather than a composite view.

Current-Cycle Context

The CEI is useful because no single economic release captures the whole economy. Payrolls can look strong while production softens. Sales can weaken before employment responds. Income can be distorted by inflation or transfer payments. A composite coincident index pulls several current indicators into one view.

The limitation is timing. A coincident index is not built to forecast the next turn. It is better for confirming the current backdrop and comparing it with leading indicators that may be signaling a future shift.

The CEI can also help separate a current slowdown from a future warning. If leading indicators are falling but the CEI is still rising, the economy may be slowing ahead rather than contracting now. If the CEI begins falling too, the weakness has moved into current activity.

The Bottom Line

The Coincident Economic Index is a current-conditions gauge. It helps readers understand whether the economy is broadly expanding or weakening now, especially when individual data releases send mixed signals.
