Wall Street dropped with the price of oil after reports from OPEC and the International Energy Association showed that the global glut won't abate any time soon.
Global oil demand growth is slowing at a faster pace than initially predicted, the IEA said in its latest oil market review.
"Our forecast in this month's report suggests that this supply-demand dynamic may not change significantly in the coming months. As a result, supply will continue to outpace demand at least through the first half of next year," the IEA said, according to Reuters.
"With our more pessimistic outlook for the second half of 2016 refining activity and revisions to crude supply, the expected draws in the third quarter of 2016 are now lower, while the build in the fourth quarter of 2016 is higher," the IEA noted.
Meanwhile, OPEC now predicts that production from outside the group will rise in 2017, compared with a previous estimate for a decline, mainly due to new production from Kashagan, it said in its monthly report.
