Investing.com - Oil prices sank to a seven-month low on Tuesday, as concerns over a glut in the market continued to weigh on sentiment.
U.S. crude was at $43.59 at 05:00 ET, down 84 cents, or 1.89%, after falling to $43.45 earlier, a level not seen since November 14.
Brent lost 89 cents, or 1.9%, to $46.03, also the weakest level since mid-November.
Oil prices lost around 1% on Monday as concerns over a steady increase in U.S. production added to fears over a glut in the market.
The increase in U.S. drilling activity and shale production has mostly offset efforts by OPEC and other producers to cut output in a move to prop up the market.
Investors looked ahead to weekly data from the U.S. on stockpiles of crude and refined products. Industry group the American Petroleum Institute is due to release its weekly report later on Tuesday, while official data from the Energy Information Administration will be released Wednesday.
