Global Markets Fall as Investors Weigh Prospects of Global Trade War

Global stocks tumbled on Tuesday as investors’ concerns over the future health of the economy mounted after President Trump’s broad tariffs against Canada, Mexico and China went into effect.

The S&P 500 fell 0.7 percent at the start of trading on Tuesday, adding to the 1.8 percent loss on Monday that was its sharpest decline this year. Investors appeared to rush into the safety of government debt, helping to lower the yield — yields move inversely to prices — on the 10-year Treasury note to its lowest since October.

The drop in yields, however, also signaled mounting concerns about the ability of the economy to withstand incoming tariffs for too long. That concern was also evident in a shift in expectations for the number of times the Federal Reserve will cut interest rates. Investors now expect the central bank to cut rates as many as three times this year, a sudden change that reflects worries that the Fed will be pushed into lowering rates quickly to prop up an ailing economy.

“While a trade war might have short-term reflationary implications,” said Ian Lyngen, an interest rate strategist at BMO Capital Market, “it also carries with it significant risks to global growth.”

European stocks had earlier slumped as investors weighed the prospects of a global trade war after China and Canada quickly imposed tariffs of their own.

The Euro Stoxx 50 index, which comprises the eurozone’s largest companies, fell as much as 2.4 percent, its worst performance in about four months. Germany’s benchmark index, the DAX, dropped as much as 2.7 percent, erasing nearly all of its gains from the previous day when it hit a record on the promises for more European military spending.
