President Donald Trump’s expanding tariff campaign may backfire on American families, with new research by Yale University’s Budget Lab warning that the newly imposed and proposed duties could saddle U.S. households with up to $2,400 in additional costs in 2025 alone.
The analysis, released Wednesday, paints a stark picture of the cumulative effects of Trump’s trade policies—suggesting they could trigger a significant inflation spike, slower economic growth, job losses, and tighter consumer margins.
If all announced tariffs remain in place, the U.S. would face an 18% effective tariff rate—the highest seen in nearly a century, dating back to the protectionist Smoot-Hawley Act of 1930.
Tariffs Surge, Prices Follow
The study factors in new tariffs on a wide swath of imports, including Trump’s planned 50% duty on copper—a vital component for construction, electronics, vehicles, and national defense—as well as sweeping new rates targeting Brazil, Japan, South Korea, and potentially the pharmaceutical sector.
Already, copper prices surged 10%, reaching a historic high just hours after Trump confirmed the move. Analysts say this increase signals broader inflationary risks across industries dependent on copper.
“If this is the case, American businesses will pay a lot more than 10% extra to buy copper, raising prices for all products that use copper,” said Peter Schiff, Chief Economist at Euro Pacific Asset Management.
Schiff, a long-time critic of protectionist trade measures, warned the tariffs would ignite a consumer cost crisis.
“As I warned, Trump just imposed an additional 25% tariffs on imports from South Korea and Japan… Consumers need to brace for much higher prices and get used to higher interest rates.”
What Will Get More Expensive?
According to Yale’s model, clothing, shoes, electronics, metals, leather goods, and cars will bear the brunt. In the short term, clothing prices are expected to rise 37%, shoes by 39%, and electrical equipment by 26%. Long term, prices may stabilize—but not before settling 18% higher on average.
Even everyday essentials like coffee, fruits, vegetables, and orange juice—especially those imported from Brazil—are projected to become more expensive. Groceries may see more moderate increases, but they still compound the cost-of-living burden for low-income households.
GDP Loss, Jobs at Risk
The tariff blow won’t just be at the checkout counter. Yale projects a 0.7% drop in U.S. GDP in 2025 and a 0.4% increase in the unemployment rate, as businesses cut jobs or delay hiring to manage rising costs. The damage could be more permanent too: with tariffs in place long term, GDP would remain 0.4% smaller every year, amounting to an annual loss of $110 billion.
Sectors like construction, agriculture, retail, and auto manufacturing are expected to be disproportionately affected. Yale researchers did note a possible 2% increase in U.S. manufacturing, but they cautioned that this boost comes at the cost of broader economic stability.
Massive Revenue or Massive Burden?
On paper, Trump’s trade strategy could generate $2.6 trillion in revenue between 2026 and 2035, with $2.2 trillion in net gains after accounting for losses. That projection is what the Trump administration points to in defending the tariffs as a vital revenue source and a measure to “level the playing field.”
However, economists warn this windfall is heavily regressive, coming at the expense of consumers and small businesses. Most of the revenue would be collected through higher prices on imports—paid indirectly by the public—not foreign exporters.
Businesses Brace for the Blow
A KPMG survey of 300 U.S. business executives found that 83% expect to raise prices in the next six months, and more than half say tariffs have already started to squeeze their profit margins.
“The full impact on consumers is likely still to come,” said Brian Higgins, Advisory Partner at KPMG US. “Many companies are holding off price increases until August 1.”
Despite the sweeping impact, the full extent of Trump’s tariff program remains uncertain. The president has frequently shifted positions on trade policy, earning the nickname “TACO Trump”—‘Trump Always Chickens Out’—due to delays and reversals.
After global markets plunged earlier this year following the announcement of Trump’s “Liberation Day” tariffs, the White House paused implementation for 90 days. That pause expires August 1, and most of the tariffs are now slated to kick in immediately thereafter. While some countries—like China, Vietnam, and the U.K.—have reached partial agreements, Trump continues to send letters to foreign governments saying rates could still change depending on the “relationship with your Country.”
Notably, Yale’s $2,400 cost estimate does not account for potential Federal Reserve responses, such as interest rate adjustments, that could further impact household budgets. Should inflation accelerate, the Fed could be forced to hike rates again—raising borrowing costs and mortgage payments for millions.
While the Trump administration insists the tariffs are strategic and patriotic, the mounting data tells a more sobering story.
