WASHINGTON (Reuters) -Forecasts for tepid U.S. job growth in August and a rise in unemployment to 4.3%, if accurate, would confirm a softening labor market and seal the case for an interest rate cut from the Federal Reserve this month.

The Labor Department’s closely watched employment report on Friday will follow this week’s news of more unemployed people than vacancies in July for the first time since the COVID-19 pandemic. Job growth has shifted into stall-speed, with economists blaming President Donald Trump‘s sweeping import tariffs and an immigration crackdown that has reduced the labor pool. Softness in the labor market is mostly coming from the hiring side.

Trump’s levies, which have boosted the average U.S. tariff rate to the highest level since 1934, stoked fears of inflation and prompted the U.S. central bank to pause its interest cutting cycle. Just as some of the uncertainty over trade policy was starting to lift with most tariffs now in place, a U.S. appeals court ruled last Friday that most of the duties were illegal, keeping businesses in a state of flux.

“Uncertainty is the killer of the labor market,” said Ron Hetrick, a senior labor economist at Lightcast. “We have a lot of companies and such that are pausing because of tariffs, pausing because of uncertain Fed action.”

A Reuters survey of economists expected the Labor Department’s Bureau of Labor Statistics (BLS) would report that nonfarm payrolls increased by 75,000 jobs last month after rising by 73,000 in July.

Economists said job growth around these levels was more realistic given the reduction in labor supply.

Estimates ranged from no jobs added to 144,000 positions created. The initial August job count has tended to exhibit a weak bias, with revisions subsequently showing strength.

Revisions to June and July payroll counts will be under scrutiny. Sharp downgrades to May and June employment totaling 258,000 jobs raised the ire of Trump last month. Trump fired BLS Commissioner Erika McEntarfer, accusing her, without evidence, of faking the employment data.

Economists have defended McEntarfer and attributed the revisions to the ‘birth-and-death” model, a method the BLS uses to try to estimate how many jobs were gained or lost because of companies opening or closing in a given month.

“We are in a low churn labor market, with not a lot of hiring or firing happening. So that means the job growth that we do see in the economy is mainly driven by the net birth of new firms,” said Ernie Tedeschi, director of economics at the Budget Lab at Yale University.
