German institute study shows U.S. tariffs fail to cut trade deficit
A German economic study indicates that President Donald Trump's agenda supports solid growth and investment while falling short on its trade rebalancing goal. The findings point to shifts in the origins of the U.S. trade gap, even as overall import tariffs have not reduced the deficit.
Highlights
- Despite broad tariffs, the U.S. goods trade deficit rose to $130 billion in August 2024, surpassing levels from two years prior.
- Foreign direct investment inflows fell 8.2% to $248 billion in 2025, standing 18% below the 2015-2024 average, indicating weak manufacturing revival.
- The U.S.-Israeli war against Iran is increasing public debt—now $40 trillion—and raising interest rates as creditors voice sustainability concerns.
Study findings on growth, trade and investment
As reported by Reuters, a study by the German Economic Institute IW says Trump's tax cuts, tariffs and push to revive domestic manufacturing are producing mixed results. Gross domestic product growth remains solid and AI-related investment is buoyant, but job creation lags the prior administration and inflation remains above the Federal Reserve's 2% target.The report says the U.S. goods trade deficit reaches $130 billion in August, exceeding its level two years earlier despite broad import tariffs. At the same time, trade patterns shift, with the European Union's share of the deficit falling to 7% from 20% in August 2024, while China's share declines to 14% from 29%.
Efforts to bring manufacturing back also fall short in the study's assessment. Foreign direct investment inflows fall 8.2% to $248 billion in 2025, leaving them 18% below the 2015-2024 average.
Debt pressures and wider policy implications
The study also links geopolitical conflict to rising fiscal strain in the U.S. It says the U.S.-Israeli war against Iran is increasing already high public debt and pushing up interest rates, while creditors question whether the U.S. can sustain its outstanding debt of $40 trillion.Taken together, the findings suggest that tariffs are changing where the U.S. trade imbalance comes from rather than shrinking it overall. For investors and manufacturers, the report points to an economy that is still drawing AI-linked spending but remains exposed to inflation, weaker investment inflows and mounting borrowing costs.
Our earlier article on rising long-term Treasury yields explained how higher rates are tightening financial conditions across the U.S. economy, lifting mortgage costs and increasing federal interest expenses as annual deficits near $2 trillion. It also noted that geopolitical risks and heavy borrowing needs—alongside strong demand for capital to fund AI infrastructure—are adding to funding pressure, while political gridlock makes near-term deficit reduction less likely despite total U.S. debt around $40 trillion.
