Investing.com - Oil prices regained ground on Tuesday, but held near multi-year lows amid ongoing concerns over a global supply glut.
Internationally traded Brent futures were up 0.33% to $36.47 a barrel at 9.52 GMT. The global benchmark fell to $36.04 on Monday, a level not seen since July 2004.
U.S. crude futures were up 0.63% at $36.02 a barrel after falling to a 7-year low of $34.29 last week.
Both benchmarks have lost at least 35% since the beginning of the year.
Meanwhile, the spread between the Brent and the WTI crude contracts collapsed to the lowest level since 2010, on signs that the U.S. oil market is likely to grow tighter following Congress' decision to lift a 40-year old ban on domestic oil exports, while a global glut gets worse in 2016 due to soaring production in Saudi Arabia and Russia.
