What is the economic cycle?
The economic cycle (also called the business cycle) is the pattern of rising and falling economic activity as an economy moves from expansion to peak to contraction and back to a trough and recovery. While the stages are predictable in kind, their timing and length are not. Analysts track measures such as gross domestic product (GDP), employment, consumer spending, inflation, interest rates, and corporate profits to assess which stage an economy is in and to make planning or investment decisions accordingly.

Key takeaways
– The business cycle has four stages: expansion, peak, contraction, trough.
– Common indicators used to locate the cycle stage include real GDP, unemployment, inflation, consumer spending, business investment, and interest rates.
– Economists disagree about causes: explanations include money/credit cycles (monetarism), shifts in aggregate demand (Keynesian), and exogenous shocks.
– Governments and central banks use fiscal and monetary policy to moderate cycles; investors and businesses adjust strategy by stage.
– The National Bureau of Economic Research (NBER) dates U.S. cycles and relies heavily on GDP and other monthly indicators. (Source: NBER; Investopedia)
Stages of the economic cycle — what happens, indicators to watch, and practical steps
1) Expansion
What happens
– Economic output (real GDP) grows, often for two or more consecutive quarters.
– Employment rises, wages typically increase, and consumer/business confidence strengthens.
– Credit is available, borrowing costs are often low, and corporate profits generally improve.
– Money supply growth can fuel rising prices (inflation) if demand outpaces supply.
Key indicators to watch
– Rising real GDP and industrial production
– Falling unemployment rate and rising payrolls
– Rising retail sales and consumer confidence
– Upward trend in business investment and durable goods orders
– Stable or slowly rising inflation (CPI, PCE)
Practical steps
– Businesses: invest in capacity and productivity while monitoring margins; avoid excessive fixed-cost expansion without stress tests; lock in favorable financing if borrowing for durable projects.
– Investors: overweight cyclical sectors (e.g., technology, capital goods, energy) but trim positions as valuations rise; consider growth and small-cap exposure.
– Households: lock in mortgages or long‑term loans if rates are low; build an emergency cash reserve of 3–6 months of expenses (or more if income is volatile).
– Policymakers: monitor overheating indicators; be ready to tighten monetary policy or cool fiscal stimulus if inflation accelerates.
2) Peak
What happens
– Growth reaches its maximum. Output and employment are near cyclical highs.
– Some imbalances (overinvestment, asset bubbles, stretched credit) often appear.
– Inflationary pressures may accelerate and interest rates can rise.
Key indicators to watch
– GDP growth slows even if still positive
– Yield curve flattening or inversion (short rates ≥ long rates)
– Rising inflation measures and tightening credit conditions
– Slowing order backlogs and weakening business sentiment surveys (e.g., ISM)
Practical steps
– Businesses: slow discretionary expansion; run stress tests on debt-servicing capacity; conserve cash and reduce high-cost inventory accumulation.
– Investors: take profits on overextended positions; increase allocation to cash and high‑quality bonds; begin rotating to defensive sectors.
– Households: avoid taking on large variable-rate debt; accelerate savings for expected tighter conditions.
3) Contraction (including recession)
What happens
– Economic activity declines; unemployment rises, spending and investment fall.
– Prices may stagnate or decline; credit can tighten as lenders become risk‑averse.
– A sustained contraction that is deep/widespread is called a recession (or, rarely, a depression).
Key indicators to watch
– Consecutive quarterly declines in real GDP
– Rising unemployment and falling payrolls
– Declining industrial production, retail sales, and business investment
– Falling or negative inflation (disinflation/deflation) in severe contractions
Practical steps
– Businesses: focus on cost control, preserve liquidity (cash on hand), renegotiate supplier terms, delay noncritical capital projects, and shift product mix to essentials if applicable.
– Investors: favor defensive sectors (utilities, consumer staples, healthcare), increase allocation to high‑quality bonds or bond ladders, consider cash reserves, and use dollar-cost averaging for long-term investments.
– Households: prioritize debt reduction (especially high-interest), maintain or increase emergency savings, avoid forced asset sales; consider refinancing if it lowers fixed payments.
4) Trough and recovery
What happens
– Economic activity bottoms; excess supply and unemployment begin to decline as demand recovers.
– Low interest rates and policy stimulus often remain in place to support recovery.
– The trough is an opportunity to restructure finances and position for the next expansion.
Key indicators to watch
– Stabilization and then growth in GDP
– Falling unemployment or an inflection in jobless claims
– Improving PMI/business sentiment and rising consumer confidence
– Credit conditions begin to ease
Practical steps
– Businesses: invest selectively in efficiency and marketing to gain share; replenish inventories prudently; review and adapt business models for the new cycle.
– Investors: gradually increase exposure to cyclical assets and equities, use staged re-entry (laddered buys), and evaluate companies with improving earnings prospects.
– Households: consider long-term investment opportunities (retirement accounts), reassess risk tolerance, and consolidate high-cost debt where possible.
Measuring economic cycles — who dates them and what metrics matter
– The National Bureau of Economic Research (NBER) is the standard U.S. arbiter for dating recessions and expansions. NBER defines turning points by considering a range of monthly indicators (real GDP, employment, industrial production, real income, wholesale/retail sales) and often announces peaks and troughs months after they occur. (Source: NBER)
– Commonly used metrics: real GDP (quarterly), payroll and unemployment data (monthly), consumer spending and retail sales, industrial production, business investment, CPI/PCE inflation, yield curve, PMI surveys, and corporate earnings.
What causes economic cycles?
No single definitive cause; competing explanations include:
– Monetarism / credit cycle: changes in money supply and credit availability (often driven by central bank policy or financial-sector behavior) alter borrowing costs and spending, causing expansions and contractions.
– Keynesian / demand shocks: fluctuations in aggregate demand—especially investment demand—can produce self-reinforcing cycles (falling demand → layoffs → lower spending → more layoffs).
– Financial and credit shocks: banking crises, rapid credit expansions and contractions, or asset bubbles that burst can precipitate deep recessions.
– External shocks: oil price shocks, pandemics, wars, or supply‑chain disruptions can temporarily halt activity and produce cycles.
– Structural and productivity changes: long-term shifts (technology, demographics) can alter cycle amplitude and duration.
Managing economic cycles — tools and strategies
For policymakers
– Monetary policy: lower interest rates, quantitative easing, or lending facilities during downturns; raise rates or reduce accommodation during overheating to control inflation.
– Fiscal policy: stimulus (tax cuts, spending) in recessions to boost demand; fiscal restraint in overheating periods if inflation or asset bubbles threaten stability.
– Macroprudential measures: tighter lending standards, countercyclical capital buffers for banks, and regulation to dampen excessive credit growth.
For businesses
– Adopt scenario planning (best/worst/base-case) tied to leading indicators (PMI, yield curve, credit spreads).
– Maintain flexible cost structure where possible (outsourcing, variable labor contracts).
– Preserve liquidity: cash buffers, committed credit lines, staggered debt maturities.
– Monitor customer mix and product pricing power; diversify revenue streams.
For investors
– Use asset allocation and rebalancing to control risk across cycles.
– Rotate sector exposure based on cycle stage (cyclical during expansion; defensive during contraction).
– Shift duration exposure depending on interest-rate outlook; use inflation-protected securities (TIPS) when inflation risk is rising.
– Keep a cash allocation to exploit buying opportunities at cycle troughs.
For households
– Maintain emergency savings (3–12 months based on job stability).
– Avoid excessive leverage and choose fixed-rate debt when rates are low and a contraction is possible.
– Continue disciplined retirement investing (stick to long-term plans; dollar-cost average).
Practical indicator checklist to follow regularly
– GDP growth rate (quarterly)
– Unemployment rate and weekly jobless claims (monthly/weekly)
– Manufacturing and services PMI (monthly)
– Retail sales and consumer confidence (monthly)
– Inflation: CPI and PCE (monthly)
– Yield curve (10y–3m or 10y–2y spreads) and credit spreads (corporate bonds)
– Bank lending standards and money supply trends
Important caveats
– Timing is difficult: while stage characteristics are familiar, predicting exact turning points is notoriously hard.
– Cycles vary: length and severity depend on many forces (policy responses, shocks, structural shifts).
– Diversified, flexible planning is generally more robust than attempting precise cycle timing.
The bottom line
The economic cycle is a recurring pattern of expansion and contraction driven by interactions among consumer demand, business investment, credit availability, and policy choices. While the four-stage framework (expansion → peak → contraction → trough) is useful for understanding typical dynamics, real-world cycles vary greatly. Businesses, investors, households, and policymakers can reduce risk and seize opportunities by monitoring key indicators, preserving liquidity, and adjusting strategies to the likely stage of the cycle.
