USA TODAYPublished 4:05 PM EDT Jun 8, 2020It’s official: The United States is in a recession.The National Bureau of Economic Research said Monday the U.S. economy peaked in February, ending the longest expansion in U.S. history at 128 months, or about 10½ years.In truth, The announcement codifies the painfully obvious. States began shutting down nonessential businesses in mid-March to contain the spread of the coronavirus, halting about 30% of economic activity and putting tens of millions of Americans out of work.The NBER called the recession about three months after it began, the fastest such determination since the recession in 1980 and far shorter than the typical nine months to a year, says Gregory Daco, chief U.S. economist of Oxford Economics.NBER is a nonprofit organization that conducts research on a wide range of economic issues. It’s best known for its Business Cycle Dating Committee, which calls the beginnings and ends of recessions.The expansion began in June 2009, ending the Great Recession that started in December 2007.The economy’s quarterly peak occurred in the fourth quarter of last year, NBER said.Typically, an economy’s monthly and quarterly peaks coincide. This time, they happened in different periods because of “the unusual nature of this recession,” NBER said. “The economy contracted so sharply in March” that several economic measures “were significantly below their levels” in the fourth quarter.A recession is defined as a decline in economic activity that lasts more than a few months, NBER noted. That may not hold true in this case. Employers shed an unprecedented 1.4 million jobs in March and 20.7 million in April, but the Labor Department unexpectedly reported 2.5 million job gains in May as states began allowing businesses to reopen in phases. Millions more jobs are likely to be added in June as more restaurants, shops, beauty salons and other businesses start up again.The economy contracted at a 5% annual rate in the first quarter and is expected to shrink at up to a record 40% rate in the current quarter before mustering a strong rebound in the third quarter.Yet the downturn, abruptly engineered by the government to curtail the virus, has been so severe that it meets the criteria for a recession, NBER said.“In deciding whether to identify a recession, the committee weighs the depth of the contraction, its duration, and whether economic activity declines broadly across the economy,” the agency said.NBER “concluded that the unprecedented magnitude of the decline in employment and production, and its broad reach across the entire economy, warranted designation of this episode as a recession, even if it turns out to be briefer than earlier contractions.”A recession informally has been defined as a decline in economic output that lasts at least two quarters. Officially, NBER also assesses inflation-adjusted income, employment, industrial production and wholesale-retail sales.Employment peaked in February, according to Labor’s surveys of businesses and households, NBER said. Since those surveys are conducted during the week that includes the 12th of the month, ”they understate the collapse of employment during the second half of March, as indicated by unprecedented levels of new claims for unemployment insurance.”More than 42 million Americans have filed jobless claims, a reliable gauge of layoffs, since mid-March. Gross domestic product, gross domestic income and inflation-adjusted income and spending also all peaked in February, NBER said.Although economists expect a strong recovery in the second half of the year, many businesses have shut down permanently and consumers are likely to return to restaurants, stores and other gathering spots in large numbers only after a vaccine is available, perhaps by mid-2021. As a result, damage from the pandemic is likely to last years.Unemployment rose from a 50-year low of 3.5% in February to 14.7% in April before dipping to 13.3% in May. It’s expected to remain elevated at about 10% by December and 8% by the end of 2021, according to Moody’s Analytics.
