On Saturday evening, U.S. President Donald Trump took to social media to announce the introduction of a 15 percent global tariff, just a day after he had introduced a 10 percent tariff. This decision comes in light of a recent Supreme Court ruling that deemed his previous import tariffs illegal. Trump, advocating his new tariff, claimed it was supported by a more robust legal foundation than the previous plan, which faced judicial overturn.

This latest move is seen as part of Trump’s ongoing trade strategy, which has consistently relied on tariffs as a means of protecting American industries and exerting pressure on foreign governments. The Supreme Court’s recent ruling, which was decided by a conservative majority, highlighted the complex intersection of trade policy and judicial oversight, demonstrating the tensions that can arise between executive action and legal frameworks.

Moreover, Trump's tariffs have raised concerns among economists and trade experts, who warn that such measures could lead to retaliatory actions from other countries and escalate trade tensions further. The announcement has implications not just for U.S. trading partners, but also for domestic markets and consumers, as tariffs can lead to increased prices on imported goods.
