The Globe and Mail reports in its Saturday, April 12, edition that U.S. stocks surged on Friday amid ongoing volatility, reflecting fears about President Donald Trump's trade war with China. An Associated Press dispatch to The Globe reports that the S&P 500 rose 1.8 per cent after fluctuating throughout the day, while the Dow gained 619 points (1.6 per cent) and the Nasdaq jumped 2.1 per cent. Stocks rose as pressure from the U.S. bond market eased. The yield on the 10-year Treasury reached 4.58 per cent in the morning, up from 4.01 per cent a week ago, marking a significant increase in a typically stable market. Such jumps can drive up rates for mortgages and other loans going to U.S. households and businesses, which would slow the economy, and they can indicate stress in the financial system. Treasury yields, however, eased back as the afternoon progressed, and the 10-year yield regressed to 4.48 per cent. That is still higher than the day before, but not by as eye-wateringly much. Federal Reserve Bank of Boston president Susan Collins said the Fed "would absolutely be prepared" if markets become disorderly and "does have tools to address concerns about market functioning or liquidity should they arise."
