The U.S. economy ended its longest expansion in history in February and entered recession as a result of the coronavirus pandemic, the private economics research group that acts as the arbiter for determining U.S. business cycles said Monday.

The Business Cycle Dating Committee of the National Bureau of Economic Research said in a statement its members "concluded that the unprecedented magnitude of the decline in employment and production, and its broad reach across the entire economy, warrants the designation of this episode as a recession, even if it turns out to be briefer than earlier contractions."

The designation was expected, but notable for its speed, coming a mere four months after the recession began. The committee has typically waited longer before making a recession call in order to be sure. When the economy started declining in late 2007, for example, the group did not pinpoint the start of the recession until a year later.
