Lagging Indicators

What Are Lagging Indicators?

Lagging indicators are economic data series that change direction after the overall economy has already shifted. They confirm that a business cycle turning point has occurred, providing validation rather than prediction. The Conference Board publishes a Lagging Economic Index comprising seven components that typically peak after expansions have ended and trough after recessions are already underway.

The "lag" can range from several months to over a year. The unemployment rate, for example, often continues rising for months after a recession has officially ended, as businesses are slow to rehire after cutting staff.

Why It Matters for Markets

While lagging indicators may seem less useful than leading ones, they play a vital role in the analytical framework. Confirmation is valuable in a world where leading indicators frequently generate false signals. When lagging indicators confirm the direction signaled by leading indicators, confidence in the economic outlook increases.

The ratio of the Conference Board's Coincident Economic Index to the Lagging Economic Index is itself a useful leading indicator. When coincident indicators outpace lagging indicators, it suggests the economy is building momentum. When lagging indicators outpace coincident ones, it may signal that the expansion is mature and vulnerable to a downturn. This ratio effectively measures whether the economy's current performance is outrunning or falling behind its confirmed trend.

For monetary policy analysis, lagging indicators help assess whether Fed policy is having its intended effect. Inflation (a lagging indicator) may continue rising after the Fed begins tightening, requiring patience. The unemployment rate may continue falling after the economy has peaked, masking underlying weakness.

The Complete Picture

The business cycle framework uses all three indicator types together. Leading indicators (stock prices, yield curve, building permits) signal approaching changes. Coincident indicators (employment, output, income) confirm the current state. Lagging indicators (unemployment rate, CPI, bank lending) validate that the shift was genuine and not a false signal.

Effective macro analysis involves monitoring all three categories simultaneously. Divergences between them, such as leading indicators weakening while lagging indicators remain strong, create the analytical challenges and trading opportunities that define macro investing.
