The Globe and Mail reports in its Tuesday edition that Canada's main stock index rose on Monday as energy shares rallied, but the market was still trading near its lowest level in four weeks as investors worried about interest rates being kept at elevated levels for longer than previously expected. A Reuters dispatch to The Globe says that the Canadian 10-year bond yield climbed above the 4-per-cent threshold to its highest in nearly 16 years. "It feels like summer is over and, very typical for this time of year, the storm clouds are gathering -- mainly in the form of higher [bond] yields," said Elvis Picardo at Luft Financial, iA Private Wealth. "Investors have been caught off guard by how resolute the Fed seems to be in terms of keeping rates high to stamp out inflation." Last week, the U.S. Federal Reserve projected that monetary policy would be kept significantly tighter through 2024 than previously expected. The S&P/TSX Composite Index ended up 20.64 to 19,800.61, its first gain after five straight days of declines. Energy rose 1.9 per cent even as oil settled 0.4 per cent lower at $89.68 (U.S.) a barrel. The Canadian five-year bond yield also rose to a 16-year high on Monday, reaching 4.33 per cent.
