What Is the Economic Cycle?
An economic cycle, also known as abusiness cycle, refers to economic fluctuations between periods of expansion and contraction. Factors such asgross domestic product (GDP),interest rates, total employment, and consumer spending can help determine the current economic cycle stage.
Understanding the economic period can help investors and businesses determine when to make investments and when to pull their money out, as each cycle impacts stocks and bonds as well as profits and corporate earnings.
Key Takeaways
- An economic cycle is the overall state of the economy as it goes through four stages in a cyclical pattern: expansion, peak, contraction, and trough.
- Factors such as GDP, interest rates, total employment, and consumer spending can help determine the current stage of the economic cycle.

Stages of the Economic Cycle
An economic cycle is the circular movement of an economy as it moves from expansion tocontractionand back again. Economic expansion is characterized by growth and contraction, including recession, a decline in economic activity that can last several months. Four stages characterize the economic cycle or business cycle.
Expansion
During expansion, the economy experiences relatively rapid growth,interest rates tend to be low, and production increases. The economic indicators associated with growth, such as employment and wages, corporate profits and output, aggregate demand, and the supply of goods and services, tend to show sustained uptrends through the expansionary stage. The flow of money through the economy remains healthy and the cost of money is cheap. However, the increase in the money supply may spur inflation during the economic growth phase.
Peak
The peak of a cycle is when growth hits its maximum rate. Prices and economic indicators may stabilize for a short period before reversing to the downside. Peak growth typically creates some imbalances in the economy that need to be corrected. As a result, businesses may start to reevaluate their budgets and spending when they believe that the economic cycle has reached its peak.
Contraction
Acorrectionoccurs when growth slows, employment falls, and prices stagnate. As demand decreases, businesses may not immediately adjust production levels, leading to oversaturated markets with surplus supply and a downward movement in prices. If the contraction continues, the recessionary environment may spiral into a depression.
Trough
The trough of the cycle is reached when the economy hits a low point, with supply and demand hitting bottom before recovery. The low point in the cycle represents a painful moment for the economy, with a widespread negative impact from stagnating spending and income. The low point provides an opportunity for individuals and businesses to reconfigure their finances in anticipation of a recovery.
Measuring Economic Cycles
Keymetricsdetermine where the economy is and where it's headed. TheNational Bureau of Economic Research (NBER)is the definitive source for marking the official dates for U.S. economic cycles. Relying primarily on changes in GDP, NBER measures the length of economic cycles from trough to trough or peak to peak.
Since the 1950s, a U.S. economic cycle, on average, lasted about five and a half years. However, there is wide variation in the length of cycles, ranging from just 18 months during the peak-to-peak cycle in 1981 to 1982 up to the expansion that began in 2009. According to the NBER, two peaks occurred between 2019 and 2020. The first was in the fourth quarter of 2019, a peak in quarterly economic activity. The monthly peak happened in a different quarter, which was noted as taking place in February 2020.
This wide variation in cycle length dispels the myth that economic cycles are a regular natural activity akin to physical waves or swings of a pendulum. But there is debate as to what factors contribute to the length of an economic cycle and what causes them to exist in the first place.
Businesses and investors need to manage their strategy over economic cycles—not so much to control them but to survive them and perhaps profit from them.
Managing Economic Cycles
Governments, financial institutions, and investors manage the course and effects of economic cycles differently. During a recession, a government may use expansionaryfiscal policy and rapiddeficit spending. It can also try contractionary fiscal policy by taxing and running abudget surplusto reduce aggregate spending to prevent the economy from overheating during expansion.
Central banks may usemonetary policy. When the cycle hits a downturn, a central bank can lower interest rates or implement expansionary monetary policy to boost spending and investment. During expansion, it can employ contractionary monetary policy by raising interest rates and slowing the flow of credit into the economy.
During expansion, investors often find opportunities in the technology, capital goods, and energy sectors. When the economy contracts, investors may purchase companies thatthrive during recessions,such as utilities, consumer staples, and healthcare.
Businesses that track the relationship between their performance and business cycles can plan strategically to protect themselves from approaching downturns and position themselves to take maximum advantage of economic expansions. For example, if your business follows the rest of the economy, warning signs of an impending recession may suggest you shouldn't expand. You may be better off building up yourcash reserves.
Economic Theory
Monetarismsuggests that government can achieve economic stability through theirmoney supply'sgrowth rate.It ties the economic cycle to thecredit cycle, where changes in interest rates reduce or induce economic activity by making borrowing by households, businesses, and the government more or less expensive.
TheKeynesianapproach argues that changes in aggregate demand, spurred by inherent instability andvolatilityin investment demand, are responsible for generating cycles. When business sentiment turns gloomy and investment slows, a self-fulfilling loop of economic malaise can result. Less spending means less demand, which induces businesses to lay off workers. According to Keynesians, unemployment means less consumer spending, and the whole economy sours, with no clear solution other than government intervention andeconomic stimulus.
What Are the Stages of an Economic Cycle?
An economic cycle, or business cycle, has four stages: expansion, peak, contraction, and trough. The average economic cycle in the U.S. has lasted roughly five and a half years since 1950, although these cycles can vary in length. Factors to indicate the stages include gross domestic product, consumer spending, interest rates, and inflation. The National Bureau of Economic Research (NBER) is a leading source for indicating the length of a cycle.
What Happens in Each Phase of the Economic Cycle?
In the expansionary phase, the economy experiences growth over two or more consecutive quarters. Interest rates are typically lower, employment rates rise, and consumer confidence strengthens. The peak phase occurs when the economy reaches its maximum productive output, signaling the end of the expansion. After that point, employment numbers and housing starts to decline, leading to a contractionary phase. The lowest point in the business cycle is a trough, which is characterized by higher unemployment, lower availability of credit, and falling prices.
What Causes an Economic Cycle?
The causes of an economic cycle are widely debated among different economic schools of thought. Monetarists, for example, link the economic cycle to the credit cycle. Here, interest rates, which intimately affect the price of debt, influence consumer spending and economic activity. On the other hand, a Keynesian approach suggests that the economic cycle is caused by volatility or investment demand, which in turn affects spending and employment.
The Bottom Line
The economic or business cycle refers to the cyclical pattern experienced by the economy. The economy remains in an expansion phase until it reaches its peak, reversing to the downside and entering a contraction before a trough, and begins to expand once again. GDP, interest rates, employment levels, and consumer spending can help define the economic cycle. Although there are different economic theories to explain what drives the economic cycle, the conditions associated with each stage can impact business and investment decisions.
As an enthusiast and expert in economics, I can confidently delve into the intricacies of the economic cycle discussed in the article. My deep understanding of economic concepts, coupled with my ability to analyze and synthesize information, positions me to elucidate the various facets of the economic cycle.
The economic cycle, also known as the business cycle, encapsulates the fluctuations an economy undergoes, oscillating between periods of expansion and contraction. The article rightly identifies key determinants of the economic cycle, such as gross domestic product (GDP), interest rates, total employment, and consumer spending. These factors collectively contribute to shaping the overall state of the economy as it moves through four distinct stages: expansion, peak, contraction, and trough.
During the expansion phase, characterized by robust economic growth, interest rates are low, and production increases. Indicators like employment, wages, corporate profits, and aggregate demand all show positive trends. However, this phase may also introduce the risk of inflation due to the surge in the money supply.
The peak signifies the pinnacle of growth, where economic indicators stabilize before descending. This phase often brings about imbalances in the economy, prompting businesses to reassess their budgets and spending strategies.
Contraction, the subsequent stage, involves slowing growth, falling employment, and stagnant prices. Oversupply in the market can lead to a recessionary environment, and if unchecked, it may escalate into a depression.
The trough, the low point of the cycle, marks the economy's recovery phase. This period offers an opportunity for individuals and businesses to reconfigure their finances in anticipation of the impending upturn.
Measuring economic cycles involves key metrics, with the National Bureau of Economic Research (NBER) serving as the authoritative source for official cycle dates in the United States. The length of economic cycles can vary widely, dispelling the misconception that they follow a regular, predictable pattern.
Managing economic cycles requires diverse strategies from governments, financial institutions, and investors. Fiscal policies like deficit spending during recessions or budget surpluses during expansions, along with monetary policies such as interest rate adjustments, are tools used to navigate these cycles.
The article touches upon economic theories, highlighting the Monetarist view tying the economic cycle to the credit cycle, and the Keynesian perspective, attributing cycles to changes in aggregate demand driven by inherent instability and volatility in investment demand.
In conclusion, the economic cycle is a dynamic and complex phenomenon. Understanding its stages, measuring its metrics, and employing appropriate strategies are crucial for businesses and investors to navigate and potentially capitalize on the cyclical nature of economies.
