The torrent of Americans filing for unemployment insurance skyrocketed last week as more than 6.6 million new claims were filed, the Labor Department reported Thursday. That brings to 10 million the total Americans who filed over the past two weeks. Economists surveyed by Dow Jones had expected 3.1 million for last week, one week after 3.3 million filings in the first wave of what has been a record-shattering swelling of the jobless ranks. The previous week's total was revised higher by 24,000. Stock market futures gave up most of their previous gains in the morning but still pointed to a slightly higher open on Wall Street.

On an unadjusted basis, the total was 5.8 million, a number that some economists consider more relevant because seasonal adjustments are less relevant due to the unusual impact the coronavirus-induced shutdown has had on the economy. "Sadly, this probably still underestimates the actual numbers because of the overload in the systems and not every call getting through," said Liz Ann Sonders, chief investment strategist at Charles Schwab. "Even if we're accurately calculating the numbers, we still likely have worse to come."

The four-week moving average, which smooths fluctuations, was 2.054 million, up 327,250 from a week ago and the highest since Jan. 14, 2017. Before the coronavirus shut down major parts of the economy, the highest week for claims was 695,000 in 1982. The Great Recession high was 665,000 in March 2009. However, the sudden shutdown from social distancing policies caused a cascade of joblessness unlike anything the nation has ever seen. "Not only was the number worse than expected, but with lockdowns becoming stricter and being extended, we should anticipate further surges in jobless claims over the coming weeks," said Seema Shah, chief strategist at Principal Global Investors.

Those at the lower end of the wage scale have been especially hard hit during a crisis that has seen businesses either cut staff outright or at best freeze any new hiring until there's more visibility about how efforts to contain the coronavirus will work. "We've lived through the recession and 9/11. What we're seeing with this decline is actually worse than both of those events," said Irina Novoselsky, CEO of online jobs marketplace CareerBuilder. Every state reported an increase in claims for the week ending March 21. The biggest in terms of total filings were Pennsylvania (362,012), Ohio (189,263) and Massachusetts (141,003). The smallest gains came in South Dakota (1,571), West Virginia (2,671) and Vermont (3,125).
