The Financial Post reports in its Wednesday edition that for weeks, the talk on Wall Street was how markets have been unusually subdued, even calm. A Bloomberg dispatch to the Post says that in Bank of America's latest survey, investors were the most bullish since July, 2021, and reported record low cash levels. Now, however, with a clash over Greenland throwing the European and American alliance into disarray and Japanese bonds plunging, the calm is breaking. As stock markets opened on Tuesday, the "Sell America" trade came back in full force. The S&P 500, Treasuries, the dollar and bitcoin all posted losses. The VIX index, a measure of expected stock-market swings also called the "fear index," is at its highest since November. The scale of the moves shows that investors' willingness to shrug off earlier shocks -- including the White House's capture of Venezuela's leader and its renewed attacks on the Federal Reserve -- is beginning to erode. The chaotic style of the White House, such as President Donald Trump adding French champagne to his list of tariff threats, is putting a chill on market confidence. One way to defuse tensions is if Greenland to keep sovereignty, but grants the U.S. more military access.
