• Trump announces a 15% tariff following a Supreme Court ruling invalidating his previous tariffs.
• Uncertainty surrounds trade agreements as countries reassess commitments under the new tariff regime.
• Experts predict economic instability as businesses navigate shifting tariff rates.

The recent ruling by the U.S. Supreme Court has significant implications for President Donald Trump’s tariff policies, leading to the imposition of a 15% global tariff under Section 122 of the Trade Act of 1974. This decision came after the court struck down the use of the International Emergency Economic Powers Act (IEEPA), which Trump previously relied upon to impose broad tariffs, raising concerns among U.S. trading partners about the future of trade agreements made over the past year, according to SCMP and CBS News.

Trump's response, which included increasing the tariff rate from an initial 10% to 15% within days, has left many nations questioning the legitimacy of the trade deals they negotiated, particularly those that involved prior tariff rates higher than the new blanket rate. Economists and trade experts argue that this sudden shift creates "huge uncertainty" for businesses and countries alike, as they navigate through a politically charged and fluctuating environment, according to LA Times and Al Jazeera.

Following the Supreme Court's decision, trade representatives from various countries, including India and members of the European Union, are hesitating to finalize deals that could be adversely affected by the new tariffs. For instance, India has postponed a planned trade delegation to Washington set to finalize an interim agreement that included tariff considerations that are now outdated, as reported by BBC News and CBS News.

Market reactions also indicate heightened anxiety, with stock futures dropping and commodities such as gold seeing increased interest as a safe haven amid the turmoil. Economists warn that the erratic tariff landscape can deter investment and hinder economic growth, leading to long-term detrimental effects for both the U.S. economy and its trading partners, as highlighted by Al Jazeera and LA Times.

Furthermore, Trump's assertion that he can independently impose tariffs without needing further congressional authorization has been met with skepticism, as experts indicate that the current economic conditions do not reflect a balance-of-payments crisis, undermining the justification for such aggressive tariff measures. This stance leads to speculation about potential legal challenges and further litigation that could arise from the hastily applied tariffs, according to LA Times and CBS News.

The future of international trade relationships remains uncertain, with analysts predicting that negotiations may stall until a clearer understanding of the legal landscape and procedural processes around these tariffs emerges. Policymakers and economists continue to call for stability as they navigate the potentially adverse consequences of Trump's new tariff regime, as detailed by SCMP and Al Jazeera.
