Oil prices fell for a seventh straight session on Monday, coming close to their 11-year lows, on growing fears that the global oil glut would worsen in the months to come in a pricing war between key producers. Brent crude (LCOc1) fell by 3.4 percent to below $37 a barrel for the first time since December 2008 and U.S. West Texas Intermediate (WTI) (CLc1) sank 2.5 percent below $35 a barrel. Brent traded less than 50 cents above the lows last seen during the 2008 financial crisis of $36.20 a barrel.
