Republican presidential nominee Donald Trump announced a new strategy to defend the US dollar's global dominance by threatening a 100% tariff on goods from countries that move away from using the dollar in international trade. This proposal, revealed during a rally in Wisconsin, is part of a broader tariff platform aimed at countering de-dollarization efforts by countries like China, India, Brazil, Russia, and South Africa. Trump emphasized that the dollar has been 'under major siege' for the past eight years and reaffirmed his commitment to maintaining it as the world’s reserve currency. This stance is meant to appeal to working-class voters in key battleground states like Wisconsin, where a recent poll shows Democratic rival Kamala Harris leading Trump by 8 percentage points. The rally in Wisconsin concluded a campaign swing that included stops in Pennsylvania, North Carolina, and New York City. Harris, meanwhile, spent her time preparing for an upcoming debate with Trump.
