Post-WWII US Recessions: Every NBER-Dated Cycle Since 1945

The National Bureau of Economic Research Business Cycle Dating Committee has identified twelve US recessions since the end of the Second World War. Together they have averaged 10.3 months in duration and a 2.4 percent contraction in real Gross Domestic Product, peak to trough. Pre-WWII recessions, by contrast, averaged closer to 18 months. The post-WWII shortening of the average business cycle reflects the institutional infrastructure built after 1933 to dampen downturns: deposit insurance, unemployment compensation, social security, and a Federal Reserve willing to act as lender of last resort.

This page summarises every NBER-dated post-WWII US recession with start date, end date, duration, peak-to-trough real GDP change, peak unemployment rate, and primary causal factors. Each row links through to a dedicated deep-dive page where one is available.

The Twelve Post-WWII Recessions

NBER officially dates business cycles by examining six monthly indicators: real GDP, real personal income less transfer payments, nonfarm payroll employment, household-survey employment, real manufacturing and trade sales, and industrial production. The Committee declares the start (peak) and end (trough) of each cycle retrospectively, typically 6 to 18 months after the turning point, to allow data revisions to settle.

The twelve cycles since 1945, in chronological order:

The 1948-49 recession was the first true post-war business cycle, an 11-month inventory correction as the economy completed its transition from wartime to peacetime production. Real GDP fell 1.7 percent and unemployment peaked at 7.9 percent. The 1953-54 recession followed the end of the Korean War, with sharp defence spending cuts driving a 10-month, 2.7 percent contraction. The 1957-58 Eisenhower recession was sharp and short at eight months, contracting GDP by 3.7 percent as the Federal Reserve tightened to slow inflation while postwar autos demand exhausted. The 1960-61 recession, also 10 months, was driven by Federal Reserve tightening into the 1960 presidential election cycle.

The 1969-70 recession opened the troubled 1970s with an 11-month, 0.6 percent GDP contraction. The 1973-75 recession was the most severe of the postwar period until that point, lasting 16 months and contracting GDP by 3.2 percent. Its causes included the OPEC oil embargo (oil prices rose roughly four-fold between October 1973 and January 1974), the August 1971 collapse of the Bretton Woods gold-dollar system, and the Nixon-era wage and price controls that had distorted the supply side of the economy. The 1980 recession was the shortest of the century at six months, but it bookended with the 16-month 1981-82 recession (driven by Federal Reserve Chairman Paul Volcker pushing the federal funds rate to a peak of 19 percent to break embedded inflation expectations) to form what historians often describe as a double-dip.

The 1990-91 recession ran eight months and contracted GDP by 1.4 percent. Its proximate cause was the Iraqi invasion of Kuwait (which doubled oil prices in three months) combined with the legacy stress of the savings and loan crisis. It was also the first post-WWII recession to be followed by what economists came to call a jobless recovery, where output rebounded quickly but employment took years to follow. The 2001 recession, eight months at the mildest GDP contraction (-0.3 percent), was triggered by the dot-com bubble bursting and amplified by the September 11 attacks.

The 2007-09 Great Recession is by far the most severe post-WWII downturn. It lasted 18 months, contracted real GDP by 4.3 percent peak to trough, and pushed unemployment to a peak of 10.0 percent in October 2009. Its cause was a financial crisis: subprime mortgages, opaque securitisation, the September 2008 collapse of Lehman Brothers, and the cascading freeze of credit markets globally. The policy response included the Troubled Asset Relief Program, the first round of Federal Reserve quantitative easing, and the American Recovery and Reinvestment Act. Without these, most economists believe the contraction would have been deeper and longer.

The 2020 COVID recession is the strangest cycle in the NBER series. It lasted just two months (February to April 2020), making it the shortest post-WWII recession by a wide margin. But it was also the deepest, with real GDP contracting 9.1 percent and unemployment spiking to 14.7 percent in April 2020. The cause was unprecedented: a public-health-driven shutdown of broad swathes of the economy, accompanied by an equally unprecedented fiscal and monetary response (the CARES Act, multiple rounds of stimulus payments, and emergency Federal Reserve facilities) that pulled the economy out of contraction within months.

Decade-by-Decade Analysis

The 1950s and 1960s were the era of routine, mild business cycles. Three recessions fell in those two decades, each contracting GDP between 1.6 and 3.7 percent and lasting between eight and ten months. Recovery was rapid in each case. This was the period when Keynesian-influenced fiscal management was at its most confident, and the experience of these decades cemented the assumption that the modern policy state could prevent depressions.

The 1970s broke that confidence. The 1973-75 recession combined supply-side inflation (oil shock), a productivity slowdown, and the abandonment of the Bretton Woods exchange-rate system. It produced stagflation, a phenomenon previously thought theoretically impossible: rising inflation alongside rising unemployment. The 1980s opened with the Volcker double-dip recessions of 1980 and 1981-82, which together pushed unemployment to a peak of 10.8 percent in November 1982 (the highest postwar reading at that point), but successfully broke the inflation expectations that had become entrenched in the 1970s. The 1990s and the early 2000s were comparatively quiet, with two relatively mild eight-month recessions (1990-91 and 2001) bracketing the longest US economic expansion in history at the time.

The 2010s contained zero NBER-dated recessions, the only such decade in the post-WWII period. The expansion that began in June 2009 ran for 128 months until February 2020, breaking the previous duration record. The 2020s opened with the two-month COVID anomaly, after which the expansion that began in May 2020 has continued through 2026 (subject to the live indicator dashboard on the homepage).

Are Post-WWII Recessions Getting Shorter?

The simple answer is yes, on average. The first six postwar recessions (1948-49 through 1980) averaged 10.7 months. The most recent six (1981-82 through 2020) averaged 9.8 months. The compression is even more striking if the COVID two-month outlier is excluded: the median post-1980 recession is closer to ten months, in line with the postwar norm.

The structural reasons for shorter cycles include deposit insurance preventing bank runs from compounding contractions, automatic fiscal stabilisers (unemployment insurance and means-tested transfers) providing demand support without legislative delay, and a Federal Reserve that since the 1980s has been willing to cut rates aggressively at the first sign of stress. Pre-WWII contractions sometimes lasted three or four years because none of these mechanisms existed: the Federal Reserve in 1931-33 tightened into the contraction, deposit runs wiped out household savings, and there was no unemployment insurance to provide income support to displaced workers.

The 18-month duration of the 2007-09 Great Recession is the conspicuous exception to the shortening trend. Its length reflected the depth of the financial-system damage and the time required to recapitalise banks and unfreeze credit markets. Even with TARP and emergency lending, the housing market did not bottom until 2012 and the labour market took until late 2015 to return to pre-recession unemployment.

Are Post-WWII Recessions Getting Deeper?

The picture on depth is more mixed. The deepest ordinary postwar recession was 1973-75 at -3.2 percent GDP contraction, surpassed by the Great Recession at -4.3 percent and then by COVID at -9.1 percent. Excluding the COVID public-health anomaly, the average GDP contraction has shifted from approximately -2.0 percent in the first six cycles to approximately -2.5 percent in the most recent five, modestly deeper but not dramatically so.

What has changed more is the post-recession recovery shape. The 1948-49, 1953-54, 1957-58 and 1960-61 cycles all featured V-shaped recoveries: rapid drops, equally rapid rebounds, with both output and employment back to pre-recession trend within 12 to 18 months. The 1990-91, 2001 and 2007-09 recessions all featured jobless recoveries, where output recovered relatively quickly but employment took years to follow. The 2020 cycle, despite its depth, recovered with V-shape characteristics on aggregate output but the labour market sectorally diverged into what some economists called a K-shape, with high-income remote-capable workers recovering quickly and low-wage in-person workers facing extended displacement.

Comparison with Pre-WWII Recessions

The NBER chronology runs back to 1854, with 34 dated US recessions in the 172-year period to 2026. The pre-WWII average duration was approximately 18 months and the average depth was substantially worse. Pre-WWII contractions sometimes contracted output by 8 to 10 percent or more (as in 1907-08, 1920-21, and most catastrophically 1929-33). Pre-WWII recoveries were also slower, often punctuated by intermediate panics that triggered double-dip dynamics.

The post-1945 institutional architecture changed the cyclical dynamics in three measurable ways. First, the absolute frequency of recessions has fallen modestly: 22 recessions in the 91 pre-WWII years, 12 in the 81 post-WWII years, a decline from one every four years to one every seven. Second, average duration roughly halved (18 months to 10 months). Third, the most catastrophic outcomes (8 to 10 percent GDP contractions, 20 percent or higher unemployment) have been avoided in the post-WWII period (with the COVID flash crash an unrepresentative outlier).
