Your hours got cut by a quarter. Your fund covered it.
The story so far Business at the bike shop has been great for two years, and you earn $2,400 a month. Then the economy slows down. People stop buying new bikes, and the owner cuts everyone's hours by a quarter. Your pay drops to $1,800, a gap of $600 a month. The slowdown lasts 6 months. Your $3,600 emergency fund from Lesson 3.2 covers it exactly. Then people start fixing old bikes, sales come back, and so do your hours. You just lived through one turn of the business cycle. This lesson shows why it happens, how to tell where we are, and how to come through it fine.
The business cycle is the economy's pattern of growing (a boom) and shrinking (a recession), over and over, at an uneven pace.
Recessions bring layoffs, falling stocks and lower rates. Knowing the pattern helps you prepare instead of panic.
Watch a few signals, keep an emergency fund in good times, and keep investing in bad ones.
Economists at banks and the Fed forecast the cycle. A committee at the National Bureau of Economic Research (NBER) officially dates recessions. Portfolio managers adjust investments for it.
What you're looking at: a sketch of the business cycle. The wavy line is the economy's output over time; the dashed line is its long-run trend, which rises. The economy grows (expansion), tops out (peak), shrinks (contraction) and bottoms out (trough), then grows again.
The cycle, phase by phase.
Over decades the US economy grows, but never in a straight line. It speeds up, overheats, slows down, shrinks, and recovers. Each phase changes your job, your loan rates and your investments.
Four phases
The business cycle has four phases. Expansion: GDP grows, businesses hire, unemployment falls. Peak: the top, when growth is hottest and prices often rise fast. Contraction: GDP shrinks, businesses cut back, layoffs spread. Trough: the bottom, before growth returns. The cycle isn't on a schedule: some booms last over a decade, some recessions just a few months.
- The bike shop
- Two good years were the expansion. Hours cut by a quarter: $2,400 × 0.75 = $1,800, during the contraction. Hours coming back meant the trough had passed.
What you're looking at: a made-up business cycle, not real data. Slide through time and the dot moves along the economy's path. The panel shows what usually happens in each phase, and what to do with your money.
What makes it a recession
A recession is the contraction phase when it's big, broad and lasts more than a few months. A common rule of thumb is two quarters in a row of shrinking real GDP (Lesson 9.1). Officially, a committee at the NBER decides, often months after it started. Since 1945, the average US expansion has lasted about 5 years and the average recession about 10 months.
- The Great Recession
- December 2007 to June 2009: 18 months. Unemployment peaked at 10% in October 2009.
- The 2020 recession
- February to April 2020: just 2 months, the shortest on record, but unemployment hit 14.8%.
Reading the signs
Economists sort data by timing. Leading indicators tend to turn first: stock prices, building permits for new homes, new claims for unemployment benefits. GDP moves with the economy. Lagging indicators turn last: the unemployment rate often keeps rising for months after a recession is over.
- Leading
- Fewer customers walking in to buy new bikes, before any hours were cut.
- Lagging
- The owner waited until sales were clearly back before restoring hours.
Who steps in
In a recession, the Fed usually cuts interest rates (Lesson 9.2) so borrowing gets cheaper and people and businesses spend again. When the economy runs too hot and prices rise fast, it raises rates to cool it down. Congress and the President can also cut taxes or spend more. Some help kicks in on its own, like unemployment benefits for people who lose their jobs.
- 2020
- The Fed cut its main rate to near 0% in March 2020, and the government sent relief payments to most households.
Your money through the cycle
You can't control the cycle, but you can be ready for it. In good times: build your emergency fund, invest steadily, and don't let spending rise with every raise. In bad times: lean on the fund, keep investing if your job is safe (stocks often recover before the economy does, as you saw in Unit 5), and keep building skills that make you harder to lay off.
- The gap
- $2,400 − $1,800 = $600 a month.
- How long the fund lasts
- $3,600$600 a month = 6 months, exactly as long as the slowdown.

Name the phase.
Eight made-up news headlines. Read each one and decide where the economy is in the cycle. One try each.
What you're looking at: made-up headlines written like real ones. Each describes the economy at one moment.
The logic, step by step.
Three questions place the economy on the cycle.
Step 1: Is output growing or shrinking?
- The bike shop
- Sales falling for months: the shop's own contraction.
Step 2: Is it speeding up or slowing down?
- Before the slowdown
- The shop couldn't keep bikes in stock: a sign of the peak.
Step 3: Are the leading signs turning?
- The turn
- Repair orders picked up before new-bike sales did.
Worked example: your own recession plan
- Size the risk. If your hours are cut by a quarter: $2,400 × 0.25 = $600 less a month.
- Check the fund. $3,600$600 = 6 months of cover.
- Stretch it. Trim $200 of wants and the gap is $400: $3,600$400 = 9 months, close to the average 10-month recession.
- Keep investing if you can. Stocks often bottom out before the economy does.
- Refill in the boom. When hours come back, rebuild the fund first.
The hare and lynx boom and bust.
In Canada's northern forests, snowshoe hare numbers rise and crash about every 8 to 11 years. When there's plenty of food, hares multiply. Lynx, which hunt them, multiply too. Then food runs short, hare numbers crash, and lynx numbers fall a year or two later. The forest recovers, and it starts again.
What you're looking at: an illustration of the pattern, not exact data. The solid line is hare numbers, the dotted line is lynx numbers. Both rise and crash, with the lynx a step behind.
Why this sticks. Booms plant the seeds of busts, and busts clear the way for the next boom. The hares that make it through are the ones with a safe burrow. Your emergency fund is that burrow.
The page you'd copy down.
- Business cycle: expansion → peak → contraction → trough → expansion. Not on a fixed schedule.
- Recession: a big, broad drop lasting more than a few months. Rule of thumb: two quarters in a row of shrinking real GDP. The NBER makes it official.
- Since 1945: expansions average about 5 years, recessions about 10 months. 2007–09: 18 months, 10% unemployment. 2020: 2 months.
- Leading indicators turn first (stocks, building permits, jobless claims). Lagging turn last (unemployment rate).
- Recession: the Fed cuts rates; government may cut taxes or spend. Overheating: the Fed raises rates.
- You: emergency fund in good times; in bad times, use it and keep investing if you can. $3,600$600 = 6 months of cover.

On the job: you're a bank economist
Your bank's managers want your read on the economy. Here's this month's data:
- Real GDP grew 3% last year, but shrank slightly last quarter.
- New claims for unemployment benefits have risen for 3 months in a row.
- Building permits for new homes are down 15% from a year ago.
- The unemployment rate is still low at 4%.
Your task: which phase is the economy likely in or heading to, which signs tell you, and what might the Fed do?
See a model answer
Where we are: likely just past the peak, heading into a contraction.
Why: two leading indicators are turning down: jobless claims rising for 3 months and building permits down 15%. GDP shrank last quarter; one more quarter like that would meet the rule of thumb for a recession.
Why low unemployment doesn't change it: the unemployment rate is a lagging indicator. It often stays low until a slowdown is well underway.
The Fed: if the slowdown deepens, it will likely cut interest rates to make borrowing cheaper and support spending.
