Major U.S. stock-indexes fell more than 1.5% on Tuesday morning amid a decline in commodity prices and continuing uncertainty about when the Federal Reserve will raise interest rates. Copper prices hit a three-week low, while oil was down more than 2 percent on persistent worries about demand, especially in China. The Fed last week kept rates at near-zero levels, citing the turbulence in a tightly linked global economy, including slowing growth in China. But, Atlanta Fed President Dennis Lockhart said on Monday a rate hike later this year was still possible.
