Possible culmination of market forces challenging the validity of US tariffs
In a surprising turn of events, the US economy has shown resilience despite the turbulence caused by President Donald Trump's tariff policies. The stock market has rebounded, inflation is under control, and fears of a recession have receded. However, an in-depth analysis reveals that these tariffs have had significant short-term and potentially lasting consequences for both the US economy and the global trading system.
The tariffs imposed and scheduled under Trump have increased federal tax revenues by $171.1 billion in 2025, equating to 0.56% of the GDP. This revenue gain, however, comes with economic costs. The tariffs have contributed to about a 0.8 percentage point reduction in US real GDP growth over 2025, with a long-run persistent reduction in the size of the US economy by approximately 0.4%.
Inflationary pressures have increased, with tariff-related measures expected to raise Personal Consumption Expenditures (PCE) prices by 1–1.5% in 2025, driving consumer price inflation higher by 0.2-0.3 percentage points. This leads to reduced real disposable income and poses a risk of contraction in real consumer spending in certain quarters.
Specifically, 25% tariffs on auto imports are expected to raise US light vehicle prices by up to 11.4% if automakers pass on costs to consumers, pressuring growth and inflation. Companies warn that maintaining a tariff floor of 15% will continue to drive up consumer prices beyond the initial shock.
Retaliatory tariffs from China, Canada, and the EU have targeted about $330 billion of US exports, dampening export growth and complicating trade relations. The tariffs affect a wide array of sectors, including critical raw materials and agricultural products, disrupting global supply chains and trade flows.
The partial and threatened tariff increases, such as the recent hike on goods under the “fentanyl” tariff from 25% to 30%, create uncertainty, which tends to deter investment and trade.
In the long-term, the US economy is expected to remain about 0.4% smaller persistently due to the cumulative adverse effects of tariffs and retaliations. Higher consumer prices and costs for manufacturers could become entrenched, lowering US competitiveness globally. Trade relations with major partners remain tense, risking a prolonged period of trade disputes and fragmented global trade regimes.
If tariff policies become permanent or expand, they could crystallize a shift toward more protectionism, damaging the rules-based trading system and prompting further retaliation or a move toward regional trade blocs.
Despite these challenges, many countries have entered negotiations with the US, offering concessions they had long resisted. Investors, however, may exhibit complacency, which could lead to a lack of effectiveness in checking potentially harmful policies. The absence of immediate costs from the Trump administration's strategy is not evidence of its long-term viability.
Announcements of new or increased duties have repeatedly triggered stock market declines, but quick rebounds have followed due to exemptions, delays, and renegotiations. Pinelopi Koujianou Goldberg, a former World Bank Group chief economist and editor-in-chief of the American Economic Review, is professor of economics at Yale University.
The shift toward bilateralism is less an endorsement of Trump's approach than a pragmatic response to confronting the US directly being costly. For instance, Vietnam desires to strengthen ties with the US rather than deepen its reliance on China. Investors no longer believe the administration would follow through on its tariff threats, seeing them as part of a familiar cycle.
In conclusion, Trump's tariff policies have raised federal revenues but at the cost of slower US economic growth, higher inflation, increased consumer prices, and strained global trade relations, with long-term consequences likely including persistent economic drag and a more fractured international trade environment.
The tariff increases imposed by President Donald Trump have led to an unexpected 0.8 percentage point reduction in US real GDP growth over 2025, with a long-term persistent reduction in the size of the US economy by approximately 0.4%. This revenue gain from tariffs comes with economic costs, as inflationary pressures have increased, with tariff-related measures expected to raise Personal Consumption Expenditures (PCE) prices by 1–1.5% in 2025, driving consumer price inflation higher by 0.2-0.3 percentage points.
