The National Bureau of Economic Research, the arbiter of the start and end dates of a recession, determined that the recession that began in December 2007 ended in June 2009.

The business-cycle dating committee met by phone on Sunday and came to the determination. “In determining that a trough occurred in June 2009, the committee did not conclude that economic conditions since that month have been favorable or that the economy has returned to operating at normal capacity. Rather, the committee determined only that the recession ended and a recovery began in that month,” the committee said in a statement. The 2007-2009 recession is the longest in the post-WWII period.

The decision by the NBER means that any future downturn in the economy would be considered a new recession and not a continuation of the recession that began in 2007.

“The committee waited to make its decision until revisions in the National Income and Product Accounts, released on July 30 and August 27, 2010, clarified the 2009 time path of the two broadest measures of economic activity, real Gross Domestic Product (real GDP) and real Gross Domestic Income (real GDI). The committee noted that in the most recent data, for the second quarter of 2010, the average of real GDP and real GDI was 3.1 percent above its low in the second quarter of 2009 but remained 1.3 percent below the previous peak which was reached in the fourth quarter of 2007,” the committee said.
