Crude oil fell 3.7 percent to $45.29 a barrel, extending its losses throughout the morning, after the International Energy Agency said a global glut continued to build and U.S. oil production showed no signs of slowing.

The S&P energy index fell 1.3 percent, among the biggest decliners of the 10 primary S&P 500 sectors. Chevron Corp fell 1.4 percent to $101.03 while Noble Corp sank 6.5 percent to $13.28.
