The Globe and Mail reports in its Wednesday edition that President Donald Trump is rattling global markets. A Reuters dispatch to The Globe reports that investors are finding it hard to price the fundamental changes in the world's geopolitical dynamics. In 2026, the Trump administration ousted Venezuela's leader and controls the country. A violent crackdown on protests in Iran could lead to the United States responding. As well, Mr. Trump is aggressively pursuing the acquisition of Greenland. The European alliance, and indeed the very rules-based global order, appear to be in jeopardy. The economic landscape is precarious. Mr. Trump has issued interventionist decrees affecting credit-card rates and mortgage-backed securities, while also pressuring U.S. oil executives to invest in Venezuela. Additionally, his Justice Department continues to threaten an indictment of Federal Reserve chair Jerome Powell. Until now, though, this "Trumpian assault" on the U.S. and global rules-based order seemed at odds with the relative calm across markets. Tensions between Mr. Trump and key European allies are causing a sell-off in stocks, bonds and the dollar. Safe-haven gold has continued to climb, busting through $4,700 an ounce.
