The Economy Moves in Waves
Economies don't grow in a straight line. They expand, reach a peak, contract, hit a trough, and then recover — a pattern repeated across history known as the business cycle or economic cycle. No two cycles are identical in length or severity, but the underlying pattern is consistent enough to be useful.
Understanding where you are in the cycle doesn't let you predict the future with precision. But it does give you a framework for interpreting economic conditions and making better-informed financial decisions.
The Four Phases
Expansion. The economy is growing. GDP rises, employment increases, consumer confidence is high, and businesses invest. Credit is accessible, asset prices tend to rise, and wages grow. This is the longest phase of most cycles.
Peak. The economy reaches its maximum output. Growth begins to slow. Inflation may be running high, prompting central bank rate rises. Asset prices are often at their most elevated, and risks are building beneath the surface.
Contraction (Recession). Growth turns negative. Businesses cut costs, unemployment rises, consumer spending falls, and credit tightens. Asset prices often fall sharply. Confidence deteriorates. Two consecutive quarters of negative GDP growth is the common technical definition of a recession.
Trough. The economy hits its low point. Growth is at its weakest, unemployment is typically at its highest, and confidence is depressed. But this is also where the conditions for recovery begin to form — rates are cut, stimulus is deployed, and the cycle begins again.
Why Cycles Happen
Business cycles arise from the interaction of many forces: credit expansion and contraction, shifts in investment and confidence, supply shocks, technological changes, and policy responses. No single cause explains every cycle.
Using the Cycle
The cycle is most useful not for predicting the future but for calibrating risk. During expansions, risk appetite increases and assets appreciate — a useful tailwind, but also a time when overconfidence builds. During contractions, opportunities emerge for patient investors. Recognising where you are in the cycle helps you avoid both excessive optimism at the top and excessive fear at the bottom.
