Brent crude oil prices fell on Friday, ending a run of rallies earlier in the week, after OPEC said that its output surged in March, adding to a global glut. The Organization of the Petroleum Exporting Countries (OPEC) said that its March production jumped 810,000 barrels per day (bpd), to 30.79 million bpd which is equivalent to a third of global supply. “It seems Saudi Arabia has not had enough of low oil prices,” Singapore-based Phillip Futures said. Front-month Brent crude futures (LCOc1) were down half a dollar at $63.48 a barrel at 12.52 a.m.
