Congressional Report Warns Trump Tariffs Could Stymie US Manufacturing for 'Years to Come'

US President Donald Trump's tariff whiplash has already harmed domestic manufacturing and could continue to do so through at least the end of this decade to the tune of nearly half a trillion dollars, a report published Monday by congressional Democrats on a key economic committee warned.

The Joint Economic Committee (JEC)-Minority said that recent data belied Trump's claim that his global trade war would boost domestic manufacturing, pointing to the 37,000 manufacturing jobs lost since the president announced his so-called "Liberation Day" tariffs in April.

"Hiring in the manufacturing sector has dropped to its lowest level in nearly a decade," the Democrats on the committee wrote. "In addition, many experts have noted that in and of itself, the uncertainty created by the administration so far could significantly damage the broader economy long-term."

"Based on both US business investment projections and economic analyses of the UK in the aftermath of Brexit, the Joint Economic Committee-Minority calculates that a similarly prolonged period of uncertainty in the US could result in an average of 13% less manufacturing investment per year, amounting to approximately $490 billion in foregone investment by 2029," the report states.

"The uncertainty created by the administration so far could significantly damage the broader economy long-term."

"Although businesses have received additional clarity on reciprocal tariff rates in recent days, uncertainty over outstanding negotiations is likely to continue to delay long-term investments and pricing decisions," the publication adds. "Furthermore, even if the uncertainty about the US economy were to end tomorrow, evidence suggests that the uncertainty that businesses have already faced in recent months would still have long-term consequences for the manufacturing sector."

According to the JEC Democrats, the Trump administration has made nearly 100 different tariff policy decisions since April—"including threats, delays, and reversals"—creating uncertainty and insecurity in markets and economies around the world. It's not just manufacturing and markets—economic data released last week by the Bureau of Labor Statistics showed that businesses in some sectors are passing the costs of Trump's tariffs on to consumers.

As the new JEC minority report notes:

As independent research has shown, businesses are less likely to make long-term investments when they face high uncertainty about future policies and economic conditions. For manufacturers, decisions to expand production—which often entail major, irreversible investments in equipment and new facilities that typically take years to complete—require an especially high degree of confidence that these expenses will pay off. This barrier, along with other factors, makes manufacturing the sector most likely to see its growth affected by trade policy uncertainty, as noted recently by analysts at Goldman Sachs.

"Strengthening American manufacturing is critical to the future of our economy and our national security," Joint Economic Committee Ranking Member Maggie Hassan (D-N.H.) said in a statement Monday. "While President Trump promised that he would expand our manufacturing sector, this report shows that, instead, the chaos and uncertainty created by his tariffs has placed a burden on American manufacturers that could weigh our country down for years to come."
