What is a recession? The economic concept explained. What causes and happens during one.

Inflation has slowed significantly and growth of the nation's gross domestic product has remained solid, but some economists still expect a mild recession this year.

How could a modest downturn happen? The past two recessions were sparked by shocks to the economy – a housing crisis and a pandemic. A downshift could be triggered by the delayed effects of the Fed's 5.5 percentage points in interest rate hikes since early 2022, a campaign aimed at taming soaring inflation.

Many economists are expecting growth to slow to less than 2% next year, so it wouldn't take all that much to nudge the economy into a mild slump. If a recession does happen, how will it unfold, and what does it mean for everyday life?

What is a recession?

In simple terms, a recession is "a contraction in economic activity" or "when the economy shrinks," said Sameer Samana, senior global market strategist for the Wells Fargo Investment Institute.

To be more specific, a recession is "a significant decline in economic activity that spreads across the economy and lasts more than a few months," said Michael Pugliese, an economist with Wells Fargo.

In determining whether a recession has occurred, the nonprofit National Bureau of Economic Research doesn't just look at GDP but rather at a variety of indicators such as employment, consumer spending, retail sales and industrial production.

When it comes to defining a recession, it could be a technical recession or a true recession, said Samana.

"The biggest distinction is the severity," he explained. "A technical recession is more of a mathematical downshift. A true recession is a more meaningful contraction across a broader range of categories."

Will there be a recession in 2024?

Though economists have been forecasting a recession for a while, we almost certainly aren't in one now. And while growth is expected to slow significantly next year, inflation's recent pullback and Fed forecasts of 2024 rate cuts have lowered the odds of a slide. Keep in mind not even the best economists can predict with certainty when the next recession will begin.

But for now, the unemployment rate is still historically low at 3.7%. The job market is still solid despite a recent slowdown.

As for recession odds, some believe we can expect a recession to begin later in 2024 than they initially predicted. Economists say there's a 47% chance of a downturn in 2024, much lower than the 60% odds they gave earlier this year, according to forecasters surveyed by Wolters Kluwer Blue Chip Economic Indicators.
