March was a turbulent month for the markets, with both Canadian and US stocks experiencing sharp swings. The S&P 500 (S&P) and the Nasdaq Composite (Nasdaq) had their worst month since December 2022, tumbling 5.8% and 8.2%, respectively. The Dow Jones Industrial Average (DJIA) didn’t fare much better, dropping 4.2%, while the Toronto Stock Exchange Composite Index (TSX) was the best of a bad lot, falling ‘only’ 1.9%. The main culprit? President Donald Trump rolled out a wave of new tariffs, reigniting fears of a global trade war that could stifle economic growth and drive inflation higher.
