United States Stock Markets Rally as Court Ruling Threatens to Scrap Trump's Tariffs

Global stock markets experienced a surge this morning following a ruling by the United States Court of International Trade (CIT) that could potentially invalidate the tariffs imposed by former President Donald Trump.

The ruling, issued on May 29, 2025, stated that the legal basis under which Trump imposed tariffs on a wide range of imports was unlawful. The CIT found that the International Emergency Economic Powers Act (IEEPA), which Trump utilized to justify the tariffs, was not originally intended for this purpose and exceeded executive authority.

"Today's decision underscores the importance of adhering to our legal framework, and underscores that trade decisions cannot be made on a whim," remarked Oregon Attorney General Dan Rayfield in response to the ruling.

Should Trump's administration fail in an expected appeal, the tariffs, which have been impacting businesses since April 5, would be unwound. Refunds, including interest, would be issued to businesses that had paid tariffs under the regime. Tariffs were as high as 145% on imports from China, while imports from other nations faced tariffs exceeding 30%.

Although temporary tariff reductions have lessened the impact on imports from most countries, the ruling may hamper Trump's ability to reinstate the tariffs after the suspensions expire without negotiating comprehensive trade deals with the affected nations.

Derren Nathan, head of equity research at Hargreaves Lansdown, commented, "In this ever-changing landscape, today's development may not mark the last twist in the story. The world will closely monitor as the United States legal system seeks to hold its highest office accountable."

The ruling provided a boon to investor sentiment, with global stocks and U.S. futures rising this morning. The FTSE 100 started the day 0.6% higher, although it lost most of those gains by around 10 a.m.

Critics within the White House lambasted the ruling, with White House deputy press secretary Kush Desai arguing, "It is not for unelected judges to decide how to properly address a national emergency."

If the appeal fails, other options are available to the administration, such as expanding the use of Section 232 tariffs on national security grounds, an approach unaffected by the court ruling thus far.

The potential reversal of the tariffs had a favorable impact on the U.S. economy, with the pound experiencing a minor decline, while the FTSE 100 displayed strong initial gains before pulling back in response to the court ruling. Asian stocks also responded positively, with the Shanghai Stock Exchange gaining 0.7%, the Nikkei 1.88%, and the Hang Seng Index rising 1.35%.

Oil prices reported a boost, with Brent crude trading 1.17% higher shortly after 10 a.m., as concerns over a global economic downturn and potential U.S. recession had previously depressed prices. Gold prices, however, declined over 0.6% this morning, as the metal is often viewed as a safe-haven asset.

Historically, the IEEPA has been employed to regulate financial transactions, impose economic sanctions, and respond to declared emergencies. Since its enactment in 1977, it had never been used to impose tariffs prior to Trump's tenure.

  1. The ruling will potentially result in financial compensation for businesses that had paid tariffs under Trump's regime, as refunds, including interest, would be issued if the administration's appeal fails.
  2. The removal of the tariffs could have a positive impact on global business, as imports from various nations, including China, would no longer face high tariffs exceeding 30%.
  3. The potential repeal of the tariffs has implications for politics and finance, potentially hampering Trump's ability to reinstate the tariffs without negotiating comprehensive trade deals, and could affect the value of gold, often considered a safe-haven asset.
