The 2008 recession: how long it lasted and how deep it went

How long did the 2008 recession last?

The 2008 recession lasted 18 months, from December 2007 to June 2009, according to Federal Reserve History (The Great Recession and its aftermath). The National Bureau of Economic Research recognises December 2007 as the start. Wikipedia counts the same span as 18 months in one place and 19 months in another, which shows how the end-month convention changes the arithmetic by 1 month.

Under the technical definition the US recession ended in June or July 2009 (Wikipedia, Great Recession). A reader who needs one figure can state 18 months and name the source. The length of a recession is a dating convention for output and income, so it describes the contraction and leaves the hardship that followed to other measures.

How do the 2008 recession dates compare with the crash dates?

The S&P 500 closed at its peak on 9 October 2007, about 2 months before the recession began in December 2007. It reached its low on 9 March 2009, about 3 months before the recession ended in June 2009 (Wikipedia, United States bear market of 2007 to 2009). Share prices moved ahead of output at both turning points.

Unemployment peaked in October 2009, 7 months after the stock market bottom and 4 months after the recession ended. Three clocks therefore run in order: prices turn first, output turns second, and jobs turn last. Placing the 3 dates side by side helps a reader decide which clock matters for a given decision.

How deep was the 2008 recession in terms of output?

US real GDP fell $650 billion, or 4.3%, from peak to trough, and the Federal Reserve describes the downturn as the deepest recession since World War II. Peak-to-trough is the standard depth measure for output: it compares the highest level before the recession with the lowest level during it, and it sets aside how long the contraction took.

A depth figure of 4.3% hides the speed of the fall. Across the G20 zone, seasonally adjusted and weighted by purchasing power, real GDP declined in each of the 3 quarters from the third quarter of 2008 to the first quarter of 2009 (Wikipedia, Great Recession). The contraction was concentrated in a short window inside the 18 months.

How long did output take to return after the 2008 recession?

Real GDP regained its roughly $15 trillion pre-recession level in the third quarter of 2011, about 2 years after the recession ended in June 2009 and about 3 years and 9 months after it began. The official end date marked the bottom of the contraction, and the return to the old output level took more than 2 further years.

Household net worth followed, recovering by the fourth quarter of 2012 after a fall of nearly $13 trillion, or 20%, from its second-quarter 2007 peak (Wikipedia, Subprime mortgage crisis). In December 2012 the Federal Reserve tied low rates to an unemployment threshold of 6.5%, a sign that policy makers treated the recovery as unfinished long after the recession ended.

How deep was the 2008 recession for jobs and unemployment?

Non-farm payrolls fell by 8.6 million, or 6.2%, from a pre-recession level of 138.3 million (Wikipedia, Great Recession). The unemployment rate rose from under 5% to a peak of 10.0% in October 2009. Both are depth measures for the labour market, and they say more about household experience than GDP does.

Payrolls returned to 138.3 million in May 2014, and the unemployment rate returned to its pre-recession level of 4.7% in May 2016. The labour recovery took almost 5 years after the recession ended for payrolls and almost 7 years for the unemployment rate, against about 2 years for output. A reader who judges the recession by output alone sees a shorter episode than a worker did.

How far did the 2008 recession spread across the world?

Under the IMF definition the world economy was in a global recession only in calendar year 2009. In the first quarter of 2009, 59 of 71 countries with quarterly data were in recession at once, and trade fell sharply, unemployment rose, and commodity prices slumped (Wikipedia, Great Recession).

The spread was uneven. Poland was the only EU member to avoid a GDP recession, while China, India, and Indonesia grew substantially. For Asian readers this split matters, because it shows that exposure to the shock depended on trade and financial links as much as on distance from the United States.

How can the 2008 recession measures guide risk work today?

Three measures travel well: months of contraction, peak-to-trough output, and the year in which output and jobs regain their old levels. Applied to the 2008 recession they read 18 months, 4.3%, and 2011 for output with 2014 for jobs. As of October 2026, a stress case built on these 3 measures gives a board something concrete to test.
