Recession vs depression: what's the real difference?
Everyone hears "recession" on the news. Fewer people know who decides it, or why the word "depression" is saved for something much worse.
The short answer
A Recession is a broad drop in economic activity that lasts more than a few months. Jobs, spending, income and output all fall.
A depression is a very deep, very long recession. There's no official line for it. It's a word used for rare, severe slumps like the 1930s.
Side by side
| Recession | Depression | |
|---|---|---|
| What it is | A broad fall in economic activity | An extreme, long-lasting recession |
| Official US definition? | Yes, dated by the NBER | No |
| Usual length | Months to about a year and a half | Years |
| Jobs | Unemployment rises | Unemployment rises very sharply |
| How often | Several times in modern US history | Very rare |
| Best-known US example | Dec 2007 to June 2009 (the Great Recession) | 1929 to 1933 contraction (the Great Depression) |
Who decides a US recession?
Not the government. A group of economists at the National Bureau of Economic Research (NBER), called the Business Cycle Dating Committee, dates US recessions.
They look at many numbers: jobs, income, spending, factory output and more. They often announce the start date many months after it happened.
The two-quarter myth. Many people say a recession is "two quarters in a row of falling GDP". That's a rule of thumb, not the official test. See GDP and the GDP report explained.
Three US examples
- The Great Depression. The NBER dates the contraction from August 1929 to March 1933. Unemployment reached about 25% in 1933. Prices fell too, which made debts harder to pay.
- The Great Recession. December 2007 to June 2009, 18 months. Unemployment peaked at 10% in October 2009, after the recession had officially ended.
- The 2020 recession. February to April 2020. At two months, it's the shortest US recession on record, but job losses were huge.
Notice the 2020 one: very sharp, very short. That's why depth and length both matter.
Recession: what traders notice
- Rates. The Central bank often cuts interest rates to support the economy. See how interest rates affect stocks.
- Data days get bigger. The jobs report and Unemployment rate can move markets hard.
- Stocks often fall before it's announced. Markets look ahead, and the official call comes late.
Depression: what it changes
- It lasts long enough to change habits. People who lived through the 1930s often stayed careful with money for life.
- Policy changes. Many US rules and institutions, like the SEC (1934) and FDIC deposit insurance (1933), came out of that era.
- It's rare. Nothing since the 1930s has been called a depression in the US.
Markets and the economy are not the same thing. Stock prices sometimes start rising while the economy is still shrinking, because markets trade on what people expect next. That's why "the economy is bad, so stocks must fall" can mislead.
Which fits you?
You don't pick a recession. You plan for news days:
- Know the calendar. Jobs, CPI and GDP release at set times. See how to read an economic calendar.
- Expect bigger moves. Size down or stand aside around big releases.
- Keep your rules the same. The trend on the bigger chart and a stop on every trade still apply.
Common mistakes
- Trading the headline. "Recession fears" stories don't tell you which way price moves next.
- Waiting for the official call. By the time the NBER dates it, markets have usually moved.
- Assuming stocks must fall. They often do, but not always, and not on schedule.
- Calling every slowdown a depression. The word is for rare, extreme cases.
Questions
What is the difference between a recession and a depression?
A recession is a broad drop in economic activity lasting more than a few months. A depression is a much deeper and longer recession. There's an official dating process for US recessions, but none for depressions.
Is a recession two quarters of negative GDP?
That's a popular rule of thumb, not the official US definition. The NBER looks at many measures, including jobs, income, spending and output, before dating a recession.
How long do recessions usually last?
Modern US recessions have often lasted under a year and a half. The 2020 recession lasted two months. The Great Recession lasted 18 months.
What caused the Great Depression?
Economists still debate it, but the 1929 stock crash, thousands of bank failures, falling prices and policy mistakes are all part of the story.
