The record surge in suddenly unemployed Americans likely grew by another 4 million last week to push the total to 25 million or more since the coronavirus pandemic shut down large parts of the U.S. economy a month and a half ago.

Initial jobless claims in the seven days running from April 12 to April 18 probably grew by at least 4 million, with estimates ranging as high as 5.25 million, according to the latest MarketWatch survey of economists.

The U.S. Labor Department report is published Thursday morning at 8:30 a.m. Eastern time.

In the prior four weeks, new jobless claims soared by 5.25 million, 6.6 million, 6.9 million and 3.3 million respectively, using figures adjusted for seasonality. The actual amount of applications was a bit lower but still breath-taking.

Just two month ago, new claims were in the low 200,000s per week and sat near a half-century low.

Economists estimate the unemployment rate has leaped above 15% unofficially and is still going up. In February, the jobless rate had matched a 50-year low of 3.5%.

The torrent of new claims has overwhelmed many states. Some have had great trouble processing all the applications and others are already running out of money. While Congress has stepped in to help with billions in extra benefits, states are expected to seek more aid.

Another hiccup has been inability of states to process the claims of people previously not eligible but who now quality under loosened federal rules. They include self-employed people such as authors and Uber UBER, -1.69% drivers. Eventually those claims will be processed correctly and added to the totals.
