Oil slipped below $65 a barrel on Monday as signs that U.S. shale oil production was recovering after a recent price rally renewed concerns of a growing global supply glut. China’s latest move to bolster its economy offset some of the losses as it raised hopes that the world’s top energy consumer would help absorb supplies. Brent crude for June was down 44 cents at $64.95 (£42.08) a barrel by 1015 London time after dropping 1.6 percent last week.
