Understanding Business Cycles for CFA Level I
A business cycle is the recurring pattern of expansion, peak, contraction and trough in economic activity. For CFA Level I, you must identify each phase from data, know how firms and households behave in it, compare cycle theories, classify indicators as leading, coincident or lagging, and interpret unemployment and inflation measures.
What this chapter covers
This chapter is part of the Economics topic. It explains why economic activity moves in waves rather than in a straight line. You learn the four phases of the cycle, how output, jobs, inventories, credit and prices behave in each, and how economists explain the swings.
The chapter then moves to measurement. Indicators are grouped by timing: leading indicators turn before the economy, coincident ones move with it, and lagging ones turn after. You finish with unemployment and inflation, the two numbers most often used to judge where an economy stands. Know the definitions of the labor force, the unemployment rate and the main price indexes, including how headline and core inflation differ.
The ideas link to other parts of the paper. Cycle phase affects company earnings in Equities and Financial Statement Analysis, interest rates and credit spreads in Fixed Income, and central bank policy elsewhere in Economics. Questions here are usually conceptual, so clear definitions earn marks quickly.
Economics carries a modest share of the exam, but this chapter is mostly definitions, cause-and-effect and classification, so it is quick to learn and reliable to score on. The three-option format rewards candidates who know precise terms such as cyclical unemployment, frictional unemployment or leading indicator, because the wrong options are often close cousins of the right one. The cycle logic also helps you reason through questions in equities, fixed income and portfolio construction, so the time you spend here pays back across other topics. Remember there is no penalty for wrong answers, so always answer.
Understanding Business Cycles: topics in the order to study them
- 1Phases of the Business CycleStart here because every other topic refers to expansion, peak, contraction and trough.
- 2Resource Use and Economic Activity Across the CycleNext, see how employment, inventories, spending, credit and prices behave in each phase, which makes the phases concrete.
- 3Unemployment and Inflation MeasuresLearn these definitions before the indicators, since unemployment and inflation are the main data you use to read the cycle.
- 4Economic Indicators: Leading, Coincident and LaggingWith the phases and the core data clear, you can classify indicators by their timing against the cycle.
- 5Theories of the Business CycleFinish with the competing explanations, which are easier to compare once you know what the cycle looks like and how it is measured.
How to prepare Understanding Business Cycles
Plan for short, repeated sessions. This chapter is concept-heavy and light on calculation, so it suits phone study and commute time.
- Draw the cycle from memory: expansion, peak, contraction, trough. Label what output, jobs and inflation tend to do at each point.
- Make a one-page table of how inventories, hiring, capital spending, credit and prices behave in each phase. Test yourself by covering columns.
- Write exact definitions of the labor force, unemployed, the unemployment rate and the participation rate, then practise the arithmetic with small made-up numbers.
- Learn the types of unemployment (frictional, structural, cyclical) and the differences between headline inflation, core inflation and deflation, disinflation and hyperinflation.
- Sort indicators into leading, coincident and lagging lists, and attach a reason to each so you are not memorising blindly.
- Summarise each cycle theory in one line with its main cause, then compare them side by side.
- Finish with timed practice of three-option questions. For each miss, write down which wrong option fooled you and why.
Common mistakes in Understanding Business Cycles
Confusing the peak and trough with the expansion and contraction.
Fix: Remember the peak and trough are turning points; expansion and contraction are the stretches between them.
Counting everyone without a job as unemployed.
Fix: Count only people who are available and actively looking for work. Those not looking are outside the labor force.
Mixing up leading and lagging indicators.
Fix: Ask whether the item reflects future plans or past results. Orders and expectations lead; unemployment duration and outstanding loans lag.
Mixing up the types of unemployment.
Fix: Frictional is normal job search time, structural is a mismatch of skills or location, and cyclical comes from weak demand.
Treating headline and core inflation as interchangeable.
Fix: Headline covers all items. Core removes food and energy because they are volatile. Read which one a question uses.
Mixing up disinflation with deflation.
Fix: In disinflation prices still rise, only more slowly. In deflation the price level actually falls.
Last-day revision: Understanding Business Cycles
- The cycle has four phases: expansion, peak, contraction, trough.
- Cycles recur but vary in length and size; they are not regular or predictable.
- Early in an expansion, firms often meet demand by using existing capacity and inventories before hiring heavily.
- Near a peak, inflation pressure tends to build, and interest rates and credit costs tend to rise.
- Labor force = employed + unemployed; the unemployment rate = unemployed ÷ labor force.
- Discouraged workers leave the labor force and so do not count as unemployed.
- Unemployment types: frictional (job search), structural (skills or location mismatch), cyclical (weak demand).
- Headline inflation includes all items; core inflation excludes food and energy.
- Deflation is falling price level; disinflation is falling inflation rate that stays positive.
- Leading indicators turn before the economy; coincident move with it; lagging turn after.
- Lagging indicators help confirm a turn that has already happened.
- For each theory, ask what the main driver is: demand, supply, money, expectations or real shocks.

Understanding Business Cycles: frequently asked questions
How hard is the business cycles chapter in CFA Level I?
It is one of the easier parts of Economics. It is mostly definitions and classification with very little calculation. The difficulty comes from similar-looking terms, so precise wording matters.
Do I need a calculator for this chapter?
Rarely. You may compute an unemployment rate or a percentage change in a price index, which is simple arithmetic. Your TI BA II Plus or HP 12C is not essential here.
How should I remember leading, coincident and lagging indicators?
Link each one to the logic of timing. Indicators based on plans, orders and expectations lead. Output and employment measures move with the economy. Indicators based on past decisions or slow adjustment lag.
How does this chapter help with other topics?
Knowing the phase of the cycle helps you reason about earnings, interest rates, credit spreads and asset returns. Many questions in equities, fixed income and portfolio construction assume this background.
