In a notable shift, U.S. President Donald Trump has raised the new global tariff from 10% to 15% following a Supreme Court ruling that declared the high tariffs imposed on countries by Trump as illegal. Trump, invoking a legal provision, announced this change immediately after the court's decision, which he criticized as poorly articulated and particularly detrimental to American interests. He emphasized that the new maximum tariff is effective for up to 150 days unless Congress votes for an extension. This move is seen as both a defensive strategy to counteract the unfavorable ruling and a means to reinforce his administration's position on trade with foreign nations.

The reaction from various stakeholders, including businesses and state governments, has been one of confusion and caution. Many are grappling with the implications of these sudden changes to tariff policies and how best to adapt in this evolving environment. Although leaders publicly expressed support for the tariffs post-ruling, the complexity and potential consequences of such a policy shift have resulted in a guarded response across the board. The intricate nature of international trade relationships is highlighted by the necessity for businesses to navigate these new realities carefully.

In the wake of this announcement, the European Union (EU) has stated that it is closely monitoring the developments and maintaining open lines of communication with the U.S. This sentiment is echoed by officials in Mexico, indicating that this tariff hike is likely to spark significant discussions on trade relations not only between the U.S. and individual countries but also within broader international frameworks.
