US weekly jobless claims drop; revisions suggest labor market looser

By Lucia Mutikani

WASHINGTON (Reuters) - The number of Americans filing new claims for unemployment benefits fell last week, but annual revisions to the data showed applications were higher this year than initially thought, further evidence that the labor market was slowing.

With Thursday's weekly jobless claims report, the Labor Department updated the methodology used to seasonally adjust the initial claims and the so-called continued claims data. Prior to the COVID-19 pandemic, the unemployment insurance claims series used multiplicative factors to seasonally adjust the data.

Beginning in March 2020 that was changed to additive factors, before switching back to multiplicative models as the large effects of the pandemic on the claims series lessened.

"For consistency, the published seasonal factors are presented as multiplicative with additive factors converted to implicit multiplicative factors and will not be subject to revision," the department said in a statement. "Now that the pandemic impacts on the UI claims series are clearer, modifications have been made to the outlier sets in the seasonal adjustment models for both of the claims series."

It said this approach had resulted in larger-than-usual revisions for many weeks over the last five years.

Initial claims for state unemployment benefits dropped 18,000 to a seasonally adjusted 228,000 for the week ended April 1. Data for the prior week was revised to show 48,000 more applications received than previously reported.

Economists polled by Reuters had forecast 200,000 claims for the latest week. The government revised the claims series from 2018. These revisions mostly showed claims increasing from mid-February of this year, aligning them with other indicators that have shown the labor market fraying around the edges.

"Our initial gut instinct is that the new seasonals may overstate the upward trend to some extent, but that they capture the direction of claims better than the old seasonals," said Lou Crandall, chief economist at Wrightson ICAP. "Our early guess is that the 18,000 decline in the level for April 1 is a one-week fluke and that next week's number will move back in the direction of the prior week's level of 246,000."

The government updated seasonal factors for 2023 and revised factors for 2018 through 2022. But it added that "the most volatile economic period of the pandemic, including the period running from March 2020 to June 2021, was not revised and will continue to be based on additive adjustments."
