The Globe and Mail reports in its Tuesday edition that U.S. and Canadian stocks fell on Monday as oil prices and Treasury yields rose, with investors weighing uncertainty over the prospects for an Iran war peace deal and the impact on the Federal Reserve's rate path. A Reuters dispatch to The Globe says crude prices had jumped after President Donald Trump rejected a peace deal from Iran but pared gains on expectations that Qatari mediators would hold talks with the two countries. After retreating from highs at the start of the month, oil prices have accelerated higher in recent days as hopes that a peace deal may be on the horizon have diminished. The rising prices of crude and diesel fuel have fanned inflation worries and pushed Treasury yields higher, along with comments from Fed officials indicating that more rate hikes might be needed if price pressures fail to moderate after it raised interest rates by 25 basis points earlier this month. Early in the day, yields on 30-year Treasury bonds hit their highest levels since May, 2004, while 10-year Treasury yields touched their highest since June, 2007. The S&P/TSX Composite Index ended down 311.03 points at 35,489.86, its lowest closing level since July 31.
