The Globe and Mail reports in its Saturday edition that many of us thought the prospect of a falling stock market would deter the U.S. President from doing anything really, really dumb. The Globe's Ian McGugan writes that Wall Street analysts, political pundits and market columnists have spent the past few months reassuring the world that Donald Trump's blather is, at least in part, an artful negotiating ploy. No, Mad King Donald is not just putting on an act. He is not just trying to win a few concessions from his trading partners. Instead, the aged monarch is getting more bizarre by the minute. Mr. Trump's Rose Garden performance underlined the President's growing distance from reality. He mangled statistics. He told lies. He threw around accusations. And he kept repeating his favourite fable -- the one in which the United States, the richest, most powerful economy in the world, is somehow a poor victim of the global trading system. The market is scrambling to assess just how bad this all is, and the consensus is somewhere between "ugly" and "disastrous." Economists have slapped a "moron risk premium" on U.S. assets, just as they did on British assets in 2022 after the hapless budget of then-Prime Minister Liz Truss.
