With the crude market under turbulence, oil prices went on to slide down further on Friday and hit their lowest since the 2014 decline. The supply in the global market hiked and is more than the demand at the present. Brent fell down, at $61.89 a barrel while WTI dipped, at $53.23 a barrel. OPEC has planned a meeting on December 6, after which it is expected to halt the output.
