President-elect Donald Trump criticized BRICS nations on Truth Social, warning of “100% tariffs” and exclusion from the U.S. economy if they seek alternatives to the U.S. dollar. His comments come as BRICS—comprising Brazil, Russia, India, China, and South Africa—explores reducing dollar reliance in global trade and possibly creating a shared currency. Trump emphasized that the U.S. would not tolerate these efforts and demanded that BRICS commit to not supporting any currency that could replace the dollar, threatening sanctions for non-compliance.
