A federal court in New York blocked the global tariffs imposed by President Donald Trump, in a ruling announced on May 28, 2025, that disrupted the Republican administration’s trade policies. The decision, issued by the US Court of International Trade, found that Trump exceeded his authority by using the International Emergency Economic Powers Act (IEEPA) to apply tariffs ranging from 10% to 50% on imports from over 180 countries. The ruling, which affects the so-called “Liberation Day” tariff plan, was delivered by a three-judge panel following lawsuits claiming the measures were unconstitutional. The White House immediately appealed, arguing the court lacks jurisdiction to interfere with national emergencies. The suspension of the tariffs, enacted on April 2, 2025, brought relief to global financial markets but set the stage for a legal battle that could reach the Supreme Court.
The court’s decision comes amid heightened economic volatility, with stock markets worldwide reacting to Trump’s protectionist policies. The tariffs, justified by the president as a response to the US trade deficit, had sparked fears of recession and trade retaliations from nations like China, Canada, and Mexico.
- Immediate effects: Asian and European markets surged after the ruling.
- Global reactions: Leaders of affected nations signal negotiations to avoid new tariffs.
- Next steps: The legal dispute is expected to escalate, potentially to the Supreme Court.
Court ruling details
The US Court of International Trade, composed of judges appointed by presidents from different parties, including Ronald Reagan, Barack Obama, and Trump himself, ruled that the IEEPA does not grant the president authority to impose tariffs without Congressional approval. The court emphasized that the US Constitution assigns Congress the sole power to regulate international trade. The unanimous decision invalidated the presidential decrees that established the global tariffs, effective since April 2025.
The White House, represented by deputy press secretary Kush Desai, argued that the tariffs were necessary to address the trade deficit, labeled by Trump as a “national emergency.” The administration cited precedents, such as emergency tariffs imposed by Richard Nixon in 1971, to defend the measure’s legality. However, the judges rejected the comparison, stating the current context does not meet the “unusual and extraordinary threat” required by the law.
- Legal basis: The IEEPA allows emergency actions but not broad tariff imposition.
- Unanimous ruling: The three-judge panel categorically struck down the decrees.
- Immediate appeal: The White House filed an appeal minutes after the verdict.
Tariff background
Trump’s tariffs, announced on April 2, 2025, ranged from 10% for Latin American countries, like Brazil, to 30% for Asian nations, with reciprocal rates reaching 125% against China. The strategy aimed to reduce the US trade deficit, exceeding $1 trillion annually, and boost American reindustrialization. Industries such as steel, aluminum, automobiles, and even film production faced specific tariffs, while products like smartphones and computers were exempted in April, easing pressures on tech giants like Apple and Dell.
The tariffs triggered turbulence in financial markets, with significant declines in Asian and European stock exchanges. Japan’s Nikkei index hit an 18-month low, and Taiwan’s markets recorded their largest single-day drop ever. Economists from Goldman Sachs and JPMorgan revised forecasts, warning of a potential US recession, with an estimated GDP contraction of 0.3%.
Global responses
Affected countries responded in varied ways. Canada and Mexico, hit with 25% tariffs, announced retaliatory measures, while China challenged the tariffs at the World Trade Organization (WTO) and imposed 84% duties on US goods. The European Union, facing 20% tariffs, paused countermeasures after the court ruling, signaling temporary relief.
Global leaders, including Japan’s Prime Minister Shigeru Ishiba and Taiwan’s President Lai Ching-te, expressed willingness to negotiate with the US. Taiwan offered zero-tariff agreements as a basis for trade deals. In Latin America, Brazil, which exports $3.2 billion in steel and aluminum to the US, is considering WTO action against specific tariffs, like those on metals under Section 232, which remain unaffected by the ruling.
- China: Raised tariffs on US goods and seeks to diversify markets.
- Canada and Mexico: Plan retaliations but await judicial outcomes.
- European Union: Halts countermeasures and focuses on bilateral talks.
- Brazil: Explores WTO options to protect metal exports.
Financial market impacts
The tariff suspension provided immediate relief to markets. US indices, like the S&P 500, posted significant gains, while Asian and European exchanges recovered some losses accumulated since April. The ruling eased pressure on US government bond yields, which had spiked amid trade uncertainty.
However, analysts caution that volatility may persist due to the threat of new tariffs. Trump warned of 50% tariffs on European goods starting June 1 but delayed the measure for 30 days to allow negotiations. Uncertainty also affects sectors like automotive, with companies like Volkswagen monitoring developments to adjust trade strategies.
Affected industries
Trump’s tariffs impacted various sectors, particularly manufacturing. The Brazilian National Confederation of Industry (CNI) noted that the US is the primary destination for Brazil’s tech exports, such as Embraer aircraft, which faced higher costs due to 10% tariffs. In Asia, semiconductor production, critical for electronics, was hit by 30% tariffs, driving up chip and equipment prices.
The film industry faced a 100% tariff on foreign productions, announced on May 4. Countries like Australia and New Zealand, hubs for Hollywood films, protested to protect their audiovisual sectors. The exemption of smartphones and computers from tariffs, however, benefited tech firms, reducing import costs for components from Taiwan and India.
- Manufacturing: Higher costs for steel, aluminum, and automobiles.
- Technology: Electronics exemptions aid companies like Apple and Dell.
- Film industry: 100% tariffs disrupt international productions.
- Agriculture: US farmers face retaliations from trading partners.
Legal and political debate
The court ruling reignited discussions about the limits of presidential power in the US. Lawsuits led by states like California, under Governor Gavin Newsom, argued that Trump violated the Constitution by imposing tariffs without Congressional approval. California, a major industrial hub, had challenged the tariffs in April, citing harm to its trade ties with Mexico, Canada, and China.
The Trump administration insists the trade deficit justifies emergency measures. Treasury Secretary Scott Bessent claimed over 50 countries began trade talks with the US since the tariffs were announced, suggesting the strategy opened doors for bilateral deals. Commerce Secretary Howard Lutnick emphasized that the tariffs aim to reposition the US in the global trade order.
Global trade repercussions
The tariff suspension altered international trade dynamics. China, which reduced its reliance on the US market from 19.2% in 2018 to 14.7% in 2024, strengthened ties with emerging markets, including Brazil. The People’s Daily, a Chinese state newspaper, highlighted the country’s economic resilience in facing trade pressures. In Europe, the tariff suspension averted escalating tensions, but the threat of new duties keeps leaders on edge.
Brics nations, like Brazil, face additional challenges. Trump warned that group members could face 100% tariffs if they pursue alternatives to the US dollar in trade. Brazil, which maintains a trade surplus with the US, seeks to avoid retaliations, but sectors like steel remain vulnerable to specific tariffs on metals.
- China: Bolsters ties with emerging markets.
- Europe: Negotiates to prevent new tariffs.
- Brics: Faces threats of high tariffs over currency issues.
- Brazil: Seeks dialogue to safeguard exports.
Ongoing negotiations
Several countries launched talks with the US to avoid tariff reinstatement. Japan, a close US ally, pursues a bilateral deal, while India signaled openness to dialogue without immediate retaliations. Vietnam, hit with 30% tariffs, also initiated discussions with the Trump administration.
The White House maintains a firm stance. Trump suggested tariffs could be used as leverage for trade concessions. The exemption of smartphones and computers, announced on April 12, was seen as a gesture to ease pressures on US firms but did little to reduce tensions with Asian partners.
Tariff timeline
Trump’s tariffs followed a path marked by announcements, suspensions, and legal challenges.
- April 2, 2025: Trump announces global tariffs, ranging from 10% to 50%.
- April 9, 2025: Most tariffs are suspended amid market volatility.
- April 12, 2025: Smartphones and computers are exempted from tariffs.
- May 5, 2025: 100% tariff imposed on foreign films.
- May 28, 2025: Court blocks most tariffs.
Strategic sectors at stake
The tariff suspension eased pressures on key sectors, but uncertainty lingers. The semiconductor industry, vital to the global economy, faces challenges due to a shortage of skilled labor in the US, limiting Trump’s reindustrialization goals. Chip production, concentrated in Taiwan and China, remains exposed to trade tensions.
In agriculture, US farmers, who backed Trump in elections, face retaliations from countries like Canada and Mexico, which raised tariffs on grains and dairy. The exemption of tech products ensured stable global supply chains, benefiting US consumers.
Business leaders’ reactions
Business leaders voiced mixed perspectives. Hedge fund manager Bill Ackman, a Trump supporter, urged tariff suspension to avoid an “economic nuclear winter.” Tech executives, like those at Apple, welcomed the electronics exemption, while automakers, represented by Volkswagen, monitor risks of new European tariffs.
In Brazil, the CNI stressed the need for bilateral talks to protect exports. Embraer, reliant on the US market, faces higher costs from steel and aluminum tariffs still in place.
Future judicial outlook
The legal battle is expected to continue, with the White House appealing to the Court of Appeals and possibly the Supreme Court. The Court of International Trade’s ruling sets a significant precedent, curbing the use of emergency powers for trade policies. States like California, which led lawsuits against the tariffs, plan to sustain legal pressure.
The Trump administration is preparing additional arguments, claiming Congress granted sufficient authority to the Executive to address trade crises. The case’s resolution could redefine the balance of power between the president and Congress in the US.
