Frequently Asked Questions
What is a recession?
A recession is a significant decline in economic activity spread across the economy, lasting more than a few months. The common shorthand is two consecutive quarters of negative GDP growth, but the National Bureau of Economic Research (NBER) uses a broader set of indicators including employment, personal income (excluding transfers), industrial production, and consumer spending. The decline must be broad, deep, and persistent to qualify as an official recession.
What causes a recession?
Recessions typically arise from a combination of factors rather than a single cause. Common catalysts include high interest rates that reduce borrowing and spending, the bursting of asset bubbles (housing, stocks), external shocks (oil price spikes, pandemics, geopolitical conflicts), loss of consumer and business confidence, financial crises that freeze credit markets, and excessive debt burdens that force widespread deleveraging. Often, multiple factors interact to create a self-reinforcing downturn.
How long do recessions last?
According to NBER data, the average U.S. recession since World War II lasts about 10 months. The shortest was the COVID-19 recession of 2020 at just 2 months. The longest since WWII was the 2007-2009 Great Recession at 18 months. By contrast, the average economic expansion lasts approximately 64 months — more than five years. This asymmetry means that while recessions are painful, expansions tend to be much longer-lived.
How can you predict a recession?
The most reliable recession predictors include: an inverted yield curve (the 10Y-2Y Treasury spread has preceded every U.S. recession since 1960 with no false signals when measured by a 3-month average), the Sahm Rule (100% accuracy since 1970), declining Leading Economic Index (LEI) readings, rising credit spreads on high-yield bonds, falling ISM Manufacturing PMI, and rapidly rising initial unemployment claims. When several of these indicators align, recession probability increases significantly. Track these indicators on the Recession Today dashboard.
What happens to stocks during a recession?
Stock markets typically decline 20-40% from peak to trough during recessions. The S&P 500 has fallen an average of 33% during post-war recessions. However, markets are forward-looking and usually begin recovering 4 to 6 months before the recession officially ends, as investors anticipate the recovery. Defensive sectors such as utilities, healthcare, and consumer staples tend to hold up better, while cyclical sectors including financials, industrials, and energy typically underperform.

What is the yield curve and why does it predict recessions?
The yield curve plots interest rates of government bonds with different maturity dates, from 1 month to 30 years. Under normal conditions, longer-term bonds have higher yields to compensate for the risk of holding them longer. When short-term yields exceed long-term yields, the curve becomes 'inverted.' This inversion signals that bond markets — the most sophisticated investors in the world — expect the central bank to cut rates in the future due to anticipated economic weakness. An inverted yield curve has preceded every U.S. recession since the 1960s, making it the single most reliable leading indicator. See the current reading: Inverted Yield Curve Guide.
What is the difference between a recession and a depression?
A depression is a more severe and prolonged economic downturn. While recessions last months, depressions can last years. The key differences are in magnitude: GDP decline in a depression typically exceeds 10% (versus 2-5% in a recession), unemployment can reach 15-25% (versus 5-10% in a recession), price deflation is more common and severe, and the recovery takes significantly longer. The last depression in the United States was the 1930s Great Depression, which lasted over a decade. No post-war recession has met the criteria for a depression.
