What is a business cycle
A business cycle is the repeating rise and fall of overall economic activity, moving through expansion, peak, contraction and trough.
"Economic activity" usually means real GDP (output adjusted for inflation), together with jobs, incomes, industrial production and retail sales.

Business cycle phases
| Phase | What happens | Typical signs |
|---|---|---|
| Expansion | Output and employment grow | Rising sales, hiring, credit growth |
| Peak | Growth tops out | Tight labour market, price pressure, often higher interest rates |
| Contraction | Activity falls across the economy | Falling output, job losses, weaker demand |
| Trough | The low point before recovery | Activity stops falling, inventories run down |
The cycle then starts again with a new expansion, often called the recovery.
A worked example (hypothetical)
Imagine a country where factories add shifts, shops report higher sales and banks lend more each quarter. That is expansion.
Demand then outruns supply and prices rise faster. The central bank raises its policy rate, and borrowing becomes more expensive. Growth slows and then stops. That is the peak.
Firms cut orders, unemployment rises and real GDP falls for several quarters in a row. That is contraction. If it is deep and broad, it is called a recession.
Eventually prices cool, the central bank lowers rates, and the decline flattens out. That is the trough. When output starts rising again, a new expansion begins.
Formal definition and edge cases
Economists usually define a recession as a significant decline in activity that spreads across the economy and lasts more than a few months. Peaks and troughs are the turning points. A full cycle is measured from one peak to the next, or from one trough to the next.
Details experienced readers should know:
- Technical recession. Falling real GDP over consecutive quarters is a common rule of thumb. It is not an official definition. Official dating bodies, such as a committee of the National Bureau of Economic Research in the US, look at many indicators.
- Dating lag. Turning points are usually confirmed months after they happen, using revised data.
- Irregular length. Cycles have no fixed duration. "Cycle" describes a pattern, not a timetable.
- Growth recession. The economy keeps growing, but too slowly to stop unemployment rising.
- Double dip. A short recovery is followed by a second contraction.
- Stagflation. Weak growth comes together with high inflation, so the usual phase signs get mixed.
- Markets lead. Stock prices often turn before the economy does. A bear market can start near a peak, and a bull market can start before the trough.
Where the term appears
- Central bank statements. Monetary policy statements discuss where the economy stands in the cycle. One example is the latest State Bank of Pakistan decision recorded on our site: SBP policy rate raised by 50 bps to 12% with effect from 27.10.2026 (MPC). Rate changes are often quoted in basis points.
- Economic calendars. MetaTrader 5 and many news sites list GDP, jobs and PMI releases. Traders use these to judge the phase of the cycle as part of fundamental analysis.
- News and reports. Headlines about "late-cycle", "soft landing" or "recession risk" all refer to business cycle phases.
Reading the cycle does not tell you what any price will do next. Leveraged forex and CFD trading can lose money fast, even when the economic picture looks clear. See risk management.

Frequent questions
What is the business cycle meaning in simple words?
It is the economy's pattern of growing, topping out, shrinking and bottoming out, then growing again.
What are the four business cycle phases?
Expansion, peak, contraction and trough.
Is every contraction a recession?
No. A recession is a contraction that is significant, broad and lasting. A mild or short slowdown may not qualify.
Can you predict the next phase?
Not reliably. Turning points are often confirmed only after the fact, and data gets revised.
Why do traders care about the business cycle?
Interest rates, currencies and stock indices often react to news about growth and inflation. The cycle gives context for those reactions, but it does not give signals.
