Recession FAQ
30 questions covering definitions, leading indicators, US recession history, personal finance strategy, and the 2026 economic outlook. Last updated April 2026.
Definitions
What is the official definition of a recession?
In the United States, a recession is officially defined by the NBER Business Cycle Dating Committee as a significant decline in economic activity that is spread across the economy and lasts more than a few months. There is no fixed rule about two consecutive quarters of negative GDP -- NBER weighs depth, diffusion across sectors, and duration across six primary monthly indicators: real personal income less transfers, non-farm payrolls, household employment, real personal consumption, real wholesale-retail sales, and industrial production.
Is the two-quarter rule for recessions accurate?
No. The two consecutive quarters of negative GDP rule is a common shorthand used by some international bodies and financial media, but it is not the US definition. The most compelling counterexample is 2022: GDP declined in both Q1 (-1.6%) and Q2 (-0.6%), yet NBER declined to declare a recession because payrolls grew by 2.7 million, consumer spending remained positive, and income held up. NBER has never stated that two negative GDP quarters are either necessary or sufficient.
Who officially declares a US recession?
The NBER Business Cycle Dating Committee -- eight senior economists appointed by the NBER Board -- officially dates US recessions. They identify the peak (last good month before the decline) and trough (last bad month before recovery) retrospectively. The announcement typically comes 6 to 21 months after the fact. For the 2007-09 recession, the peak (December 2007) was announced in December 2008, and the trough (June 2009) was announced in September 2010.
What is the difference between a recession and a depression?
There is no official definition of a depression, no committee that declares one, and no precise threshold. Economists informally define a depression as a recession with GDP declining more than 10% that lasts at least two to three years. The Great Depression (1929-1933) saw US GDP fall roughly 27% and unemployment reach 25%. By comparison, the Great Recession (2007-2009) saw a -4.3% peak-to-trough GDP decline and 10.0% unemployment -- severe by modern standards but far short of depression territory.
What is a technical recession?
A technical recession refers specifically to the two-consecutive-negative-GDP-quarters definition, which is used by the UK Office for National Statistics and the eurozone but not by the US NBER. It is called 'technical' because it is a mechanical, rule-based definition rather than a holistic economic assessment. The UK declared a 'technical recession' in late 2023 based on two small negative GDP quarters despite low unemployment.
Indicators
What is the Sahm Rule?
The Sahm Rule is a recession-detection trigger created by former Federal Reserve economist Claudia Sahm. It fires when the three-month moving average of the national unemployment rate rises 0.5 percentage points or more above its low from the prior 12 months. It has triggered at the start of every US recession since 1970 with no false positives. The current reading is 0.47, just below the 0.50 threshold. Data sourced from FRED, verified April 2026.
What does an inverted yield curve mean?
An inverted yield curve occurs when short-term US Treasury yields are higher than long-term yields -- the opposite of the normal upward-sloping curve. The most-watched gauge is the 10-year minus 2-year (10Y-2Y) spread. Inversion has preceded every US recession since 1955. Investors are effectively betting on lower future growth and future Fed rate cuts. The US yield curve was inverted for most of 2022-2025; as of April 2026 the 10Y-2Y spread has turned slightly positive at +0.21%.
What does ISM PMI tell us about recession risk?
The ISM Manufacturing Purchasing Managers' Index (PMI) is a monthly survey of supply-chain executives. Readings above 50 indicate expansion; below 50 indicate contraction. PMI is a leading indicator -- it captures new orders, production, and employment intentions before GDP data are available. Sustained sub-50 readings (roughly six months or more) have historically correlated with recession. The April 2026 reading is 48.3, signalling mild contraction but not deep recession territory.
Are initial jobless claims a good recession predictor?
Initial jobless claims (weekly unemployment insurance filings) are the most timely US labour market indicator, published with just a one-week lag. They are useful for confirming deterioration but are noisy week-to-week. The 52-week moving average is a more reliable signal. Sustained weekly readings above 300,000-350,000 historically signal recession risk. Claims have historically turned up 3-8 weeks before a recession's official start date.
What are the six NBER recession indicators?
NBER uses six monthly indicators: (1) real personal income less government transfers, (2) non-farm payroll employment, (3) employment as measured by the household survey, (4) real personal consumption expenditure, (5) real manufacturing and trade sales (wholesale-retail), and (6) industrial production. All six typically decline in a genuine recession. A significant drop in most of them that persists for more than a few months meets NBER's threshold.
History
How many recessions has the US had?
NBER has identified 34 US recession cycles dating back to 1857. Between 1857 and 1945 there were 22 recessions, averaging roughly 21 months in duration. Since 1945 there have been 12 recessions averaging 10.3 months. The shortest post-WWII recession was the 2020 COVID-19 recession at just 2 months (March to April 2020). The longest was the 2007-2009 Great Recession at 18 months.
What caused the Great Recession of 2008-2009?
The Great Recession was triggered by the collapse of a housing bubble inflated by subprime mortgage lending, lax regulation, and securitisation that spread risk opaquely through the financial system. When home prices fell from their 2006 peak, mortgage-backed securities lost value, threatening the solvency of large financial institutions. The Lehman Brothers bankruptcy (September 2008) froze credit markets globally. The recession lasted 18 months (December 2007 to June 2009), with GDP declining 4.3% and unemployment peaking at 10.0%.
Why was the 2020 recession so short?
The COVID-19 recession (March to April 2020) was the sharpest but shortest US recession on record at just 2 months. GDP fell 31.4% annualised in Q2 2020 -- the steepest single-quarter decline since records began -- but recovered quickly because: (1) the cause was an external shock (lockdowns), not structural imbalance; (2) the Federal Reserve acted within days to cut rates and launch QE; (3) Congress passed over $5 trillion in fiscal support (CARES Act, Consolidated Appropriations Act, ARP). Demand rebounded as restrictions lifted.
Were there recessions before 1945?
Yes, and they were far more common and severe. Between 1857 and 1945 the US experienced 22 recessions averaging about 21 months in duration and 35% time spent in contraction. Major pre-WWII recessions include the Long Depression (1873-79), the Panic of 1907, the Depression of 1920-21 (which lasted 18 months), and of course the Great Depression (1929-1933). The post-WWII period has been significantly more stable thanks to deposit insurance, automatic stabilisers, and active monetary policy.
What is the longest recession in US history?
Among NBER-dated recessions, the Great Depression cycle (August 1929 to March 1933) lasted 43 months. Before that, the Long Depression starting in October 1873 lasted 65 months. In the post-WWII era, the Great Recession (December 2007 to June 2009) at 18 months was the longest, followed by the 1973-1975 recession at 16 months (triggered by the OPEC oil embargo).
Personal Finance
How should I prepare my finances for a recession?
The five highest-priority actions are: (1) build an emergency fund of 6-9 months of expenses in a high-yield savings account, (2) eliminate high-interest debt (credit cards) before a potential layoff reduces your ability to service it, (3) review your job market position -- recession-resistant sectors include healthcare, utilities, and government, (4) avoid making large speculative investments at cycle peaks, and (5) review your insurance coverage. Our detailed checklist with priority ratings is at /recession-proofing-finances.
Should I invest during a recession?
Historical evidence strongly supports continuing to invest through recessions. The S&P 500 has delivered a positive 12-month return after every post-WWII recession trough except 2001 (briefly). Average one-year post-trough return: +28%. Dollar-cost averaging (investing a fixed amount on a regular schedule) outperforms attempts to time the exact trough in most historical simulations. The biggest risk is selling at the bottom and missing the recovery. See our full analysis at /recession-investing.
Which jobs are most recession-proof?
BLS occupational data and recession history suggest the most resilient sectors are: healthcare (hospitals, pharmacies, home health aides), utilities and essential services, government and public administration, grocery retail, and mental health services. The most vulnerable are: hospitality, travel, retail discretionary, residential construction, and finance (investment banking, mortgage origination). See the full 20-occupation table at /job-search-in-recession.
How long do recessions typically last?
Post-WWII US recessions have lasted an average of 10.3 months. The shortest was 2 months (COVID-19, 2020). The longest was 18 months (Great Recession, 2007-2009). Mild recessions -- like 1990-91 and 2001 -- lasted 8-9 months. More severe recessions triggered by financial crises or supply shocks tend to last longer. Recovery to peak employment typically takes considerably longer than the recession itself: 7 years after the Great Recession.
What happens to house prices in a recession?
House prices do not always fall in recessions. They fell sharply in the Great Recession (median -22% nationally, some markets -50%) because housing was the cause of that recession. In recessions caused by external shocks or manufacturing downturns, house prices have sometimes held steady or risen. During the 2020 recession, home prices actually accelerated upward due to low mortgage rates and supply shortages. The key factors are whether credit is tightening and whether unemployment is rising rapidly.
2026 Outlook
Are we in a recession in 2026?
As of April 2026, NBER has not declared a recession. The Sahm Rule reading is 0.47 (below the 0.50 trigger). The yield curve has turned slightly positive (+0.21% 10Y-2Y). Bloomberg's model puts 12-month recession probability at 35%, Goldman Sachs at 25%, the NY Fed at 28%. Key risks are tariff-driven supply shocks, sticky services inflation forcing the Fed to keep rates elevated, and weakening consumer sentiment. The economy is slowing but has not crossed the threshold of a declared contraction.
What would trigger a recession in 2026?
The most plausible 2026 recession triggers are: (1) a consumer spending retrenchment if credit card delinquency rates continue rising and households exhaust post-COVID savings buffers; (2) a credit market shock if commercial real estate losses cascade through regional banks; (3) an external demand shock from a global slowdown; or (4) a trade-war escalation that raises input costs faster than wages. A resilience factor: US labour market remains tight, with initial claims near 224,000 per week as of April 2026.
Will the Federal Reserve cut rates in 2026?
As of April 2026, market expectations (derived from fed funds futures) imply 1-2 rate cuts of 25 basis points in 2026. The Fed's primary constraint is services inflation remaining above 3%. If unemployment rises toward 4.5% or above, the Fed has historically prioritised the employment mandate and cut aggressively. A formal recession declaration would almost certainly trigger a multi-meeting cutting cycle similar to 2007-08 and 2019-20.
What is the recession probability in 2026?
Major institutions assign the following 12-month recession probabilities as of April 2026: NY Fed model 28%, Cleveland Fed model 22%, Bloomberg Economics 35%, Goldman Sachs Research 25%. The wide range reflects genuine uncertainty. Models built on yield curve inputs tend to read lower (curve has normalised); models incorporating credit spreads and PMI read higher. We update this data monthly at /current-probability-2026.
How does tariff policy affect recession risk?
Tariffs operate as a supply shock: they raise the price of imported goods, compressing consumer purchasing power and squeezing manufacturer profit margins. Unlike demand shocks, supply shocks are harder for monetary policy to offset (cutting rates stimulates demand but cannot fix supply disruptions). The 2022 experience showed that supply-side inflation can coexist with a strong labour market for 12-18 months before one breaks. Sustained broad tariffs would be stagflationary -- raising inflation while slowing growth.
