Leading vs Lagging Indicators
PMI leads, unemployment lags — and why it matters for trading
- Classify common indicators as leading, coincident, or lagging
- Explain why CBs pay extra attention to leading indicators
- Avoid trading on lagging data alone
Unemployment is the lagging indicator everyone watches. By the time it rises meaningfully, the recession is already deep. Meanwhile, PMI was screaming for months. Leading-vs-lagging is the single most overlooked filter on data — and the difference between trading early or trading last.
The three categories
Leading: changes before the economy does. PMI, building permits, new orders, yield curve shape, equity market. Coincident: changes with the economy. GDP, industrial production, retail sales. Lagging: changes after the economy does. Unemployment, core inflation, wage growth.
PMI, ISM new orders, yield curve, equities, building permits, business sentiment. Move first, predict the next 3-6 months.
Unemployment, core CPI, wages, capacity utilisation. By the time they turn, the cycle is already well into the next phase.
Why CBs care
A CB that waits for lagging confirmation will always be late. The best CBs (and traders) act on leading signals. Fed 2022's mistake: waited for lagging data (core CPI, wages) before hiking aggressively. Leading data (PMI, surprise indices) had been screaming inflation since mid-2021. Lesson: leading data is your edge over lagging-data followers.
PMI dropped below 50 for 2 months. Unemployment still at multi-year lows. Best read for the rate path?
- Leading: PMI, new orders, yield curve — change first
- Coincident: GDP, retail sales, IP — change with cycle
- Lagging: unemployment, core inflation, wages — change last
- Trade on leading; don't wait for lagging to confirm
