TL;DR
- A recession is a broad drop in economic activity that lasts more than a few months. Two quarters of falling GDP is a rule of thumb, not the official test.
- In the US, a committee of economists at the NBER dates recessions, usually many months after they start.
- By the usual signs, the US isn’t in one now: GDP grew 2.5% and 2.2% in the first two quarters of 2026, and unemployment is 4.2%.

“Recession” is one of the most searched words in economics, and one of the most misused. Here’s what it means, how it’s measured, and why markets care so much about it.
What is a recession?
A recession is a period when the economy shrinks: people spend less, companies produce less, and jobs are lost. In the US, the official judge is the National Bureau of Economic Research (NBER), a private nonprofit whose Business Cycle Dating Committee defines a recession as “a significant decline in economic activity that is spread across the economy and lasts more than a few months.”
The committee looks at three things: how deep the drop is, how widespread it is, and how long it lasts. It watches monthly data, not just GDP: jobs, real personal income, real consumer spending, industrial production and real sales.
Is a recession two quarters of negative GDP?
That’s the popular shortcut, and it’s often right, but it isn’t the rule. In 2022, the first estimates showed US GDP falling for two quarters in a row, yet employers were adding hundreds of thousands of jobs a month, and the NBER never declared a recession. The 2020 recession, on the other hand, lasted only two months, February to April, far less than two quarters.
Recent US recessions
| Recession | Dates (NBER) | Length |
|---|---|---|
| COVID-19 | February to April 2020 | 2 months |
| Great Recession | December 2007 to June 2009 | 18 months |
| Dot-com bust | March to November 2001 | 8 months |
| Gulf War | July 1990 to March 1991 | 8 months |
Since World War II, US recessions have lasted about 10 months on average; the expansions between them have lasted years.
The warning signs economists watch
- The Sahm rule: when the three-month average jobless rate rises half a point above its low of the past year, a recession has usually begun. See the live unemployment and jobs report page.
- An inverted yield curve: when short-term Treasury yields rise above long-term ones, as on the 2-year Treasury yield page, it has come before most US recessions, often by a year or more.
- Falling payrolls and rising jobless claims: job losses are usually the clearest sign once a recession is under way.
- Weak spending and factory output: consumer spending is about two-thirds of the US economy.
Is the US in a recession now?
Not by the usual measures, as of October 2026:
| Sign | Latest | Recession signal? |
|---|---|---|
| Real GDP growthannualized | +2.5% (Q1), +2.2% (Q2) | No |
| Unemployment rateSeptember | 4.2% | No |
| Sahm rulea recession signal at 0.50 | 0.00 | No |
| Payroll jobsSeptember | +29,000 | Slow, not falling |
The risks are inflation at 3.7% and a Fed that raised rates in September. For the full checklist, updated as data comes out, see is America in a recession?
What happens to markets in a recession
- Stocks usually fall before and during a recession, and often bottom before it ends, when the news is still bad.
- Treasury yields usually fall as investors buy safe bonds and the Fed cuts rates. See the 10-year Treasury yield.
- Gold has a mixed record: it rose through the 2001 and 2020 recessions and fell in the panic of late 2008 before rallying. See why gold goes up.
- Oil usually falls as demand drops. See the oil price.
The next reports to watch
The first estimate of third-quarter GDP is due on October 29 at 8:30 AM ET, the day after the Fed’s October 28 decision, and the October jobs report on November 6. All of them are on the economic calendar.
