The Globe and Mail reports in its Friday edition that North American stocks ended down on Thursday after U.S. producer price data for August and surging oil prices stoked worries the Federal Reserve will hike interest rates next week, while climbing Treasury yields made stocks less attractive. A Reuters dispatch to The Globe says the S&P/TSX Composition Index lost 400.28 points to close at 35,506.28. With supply routes through both the Strait of Hormuz and the Red Sea disrupted by the U.S.-Israeli war on Iran, Brent crude jumped 6 per cent to $107 (U.S.) a barrel, adding to inflation worries and fuelling expectations the Fed will raise interest rates at its policy meeting next Wednesday. Yields on 10-year U.S. Treasury notes rose to their highest in nearly three years, while 30-year Treasury yields hit their highest in over 19 years and two-year Treasury yields reached their highest in more than two years. Data on Thursday showed the U.S. producer price index increased in line with expectations in August on a monthly basis amid a rebound in the cost of energy products. Traders now see a 70-per-cent chance the Fed will raise interest rates by at least 25 basis points, up from 64 per cent before Thursday's report.
