The Financial Post reports in its Friday edition that President Trump's use of economic pressure on allies raises the possibility of targeted nations uniting to implement a co-ordinated "sell America" strategy involving U.S. Treasuries. The Post's Barbara Shecter writes that American stock markets briefly sold off this week after Mr. Trump announced plans for steep tariffs on EU nations and hinted at possible military action over Greenland. The idea of dumping U.S. holdings to retaliate against pressure from the United States has gained traction. University of Toronto's Munk School's Mark Manger says: "In principle, 'selling America' would be incredibly powerful because of the U.S. current account deficit. If the 'middle powers' really did that, U.S. interest rates would blow up and the dollar would fall, almost surely tipping the U.S. into a massive recession." A Denmark pension official said this week the fund planned to sell its $100-million worth of U.S. Treasuries. On Wednesday, U.S. Treasury Secretary Scott Bessent brushed off the pension fund's plan, calling the planned Treasuries dump "irrelevant" and saying that all of Denmark holds less than $10-billion of the $30.8-trillion U.S. Treasury market.
