A record 3.28 million Americans filed for unemployment benefits last week as the coronavirus pandemic shut down much of the country. The Labor Department's report for the week ended March 21 was one of the first official indicators of how many people have suddenly been forced out of work nationally.

In the prior report, for the week ended March 14, initial claims totaled 282,000.

"This marks the highest level of seasonally adjusted initial claims in the history of the seasonally adjusted series," the department said of the latest figure. "The previous high was 695,000 in October of 1982." The Labor Department's records go back to 1967.

Federal Reserve Chairman Jerome Powell, appearing on NBC's Today Show, said what businesses and analysts already know: "We may well be in a recession."

"This is a unique situation," Powell added. "People are being asked to close their business, to stay home from work, and to not engage in certain economic activity, and so they are pulling back. At a certain point, we will get the virus under control and confidence will return."

The staggering jobless claims figure was well above the levels seen during the darkest days of the Great Recession, and the worst isn't over yet, economic forecasters say.

The crisis has cut a giant swath through the energy, travel, transportation, hotel and restaurant sectors, with large and small companies suddenly forced to furlough employees.

States that depend heavily on tourism, such as Nevada and Florida, as well as oil-and-gas towns like Midland, Texas, will be especially hard hit, but the damage will be felt almost everywhere, according to a Brookings Institution report.

The hotel industry alone has lost as many as 1 million jobs this month, the American Hotel and Lodging Association says.

"It is a huge shock and we are trying to cope with it and keep it under control," says James Bullard, president of the Federal Reserve Bank of St. Louis. Earlier this week, he said unemployment would hit 30%. But he tempered those remarks Wednesday, saying he expected the number to fall again quickly.

New claims filed last week were nearly five times the number recorded during the peak of the Great Recession. In the week that ended March 28, 2009, about 665,000 new claims were filed. That was second only to the week that ended Oct. 2, 1982, when 695,000 first-time claims were filed.

"Most historical comparisons of this scale are inadequate," said Daniel Zhao, an economist with Glassdoor. "The coronavirus outbreak is economically akin to a major hurricane occurring in every state around the country for weeks on end."

The loss of that many jobs is expected to push unemployment to 5.5% — a level it last reached in 2o15 — but it's likely to climb even further. Goldman Sachs has predicted that the jobless rate could approach 13% during the next few months.

"If the number of new claims is as high as predicted and if it remains high in coming weeks, unemployment will skyrocket," the Joint Economic Committee of Congress said in a report ahead of Thursday's data.
