Investing.com - Gold hovered close to its lowest level in nearly six years on Friday, on track for a sixth straight weekly decline, weakened by the strength in the dollar and expectations of a U.S. interest rate hike next month. The Federal Reserve is widely expected to hike U.S. rates for the first time in nearly a decade when it meets next in December. Investors believe higher rates could dent demand for non-yielding bullion, while boosting the dollar.
