Brent crude jumps 2 percent on Saudi December supply cut

SINGAPORE (Reuters) - Brent crude oil prices jumped by 2 percent on Monday after top exporter Saudi Arabia announced a supply cut in December, a measure likely aimed at halting a market slump that has seen crude decline by 20 percent since early October. Front-month Brent crude futures , a benchmark for global oil prices, were at $71.59 per barrel at 0644 GMT, up by 2 percent from their last close. U.S. West Texas Intermediate (WTI) crude futures rose 1.5 percent to $61.08 per barrel.Saudi..
