JEDDAH/VIENNA — THE global oil market should be more balanced next year as China and the developing world increase oil consumption while supply of shale oil from North America and other regions grows more slowly, the Organization of Petroleum Exporting Countries (OPEC) said on Monday. In its monthly report, OPEC said it expected world oil demand to increase by 1.34 million barrels per day (bpd) in 2016, up from growth of 1.28 million bpd this year. World oil demand growth should outpace any increase in oil supply from non-OPEC sources and ultra-light oils such as condensate, increasing consumption of OPEC crude oil, it said. US crude for July was down 99 cents at $59.46. Oil falls to $63, ample supplies and Greece weigh Saudi Arabia's oil output had been 10.31 million barrels a day in April. Last month it reached 10.33 million barrels a day, according to numbers submitted by Riyadh to OPEC. Saudi Arabia increases oil production to new level in May. “This would imply an improvement towards a more balanced market,” OPEC's in-house economists said in the report. OPEC said it expected demand for its own crude oil to rise by 860,000 bpd in 2016 to 30.07 million bpd. But it cut its estimate of demand for its crude this year by 100,000 bpd to 29.21 million bpd. Oil prices are now around half their levels of a year ago with global crude oil benchmark Brent trading at around $58.50 a barrel on Monday, down from a peak above $115 in June 2014. Lower prices have squeezed high-cost oil producers and brought a sharp fall in the number of oil exploration rigs in operation, particularly across North America. OPEC said supply of oil from non-OPEC producers was expected to grow by only 300,000 bpd in 2016, down sharply from growth of 860,000 bpd this year. US oil output, which has seen rapid increases over the last five years thanks to the development of huge shale resources by “fracking”, is expected to log much more modest supply growth in 2016. “Total US liquids production is expected to grow by 330,000 bpd, just one third of the growth of 930,000 bpd expected this year,” it said. World oil supply has grown much faster than demand this year, led by OPEC as its core members in the Middle East Gulf attempt to build market share, leading to higher inventories. OPEC estimated, based on figures from secondary sources, that its own group crude oil output rose 283,000 bpd to 31.38 million bpd in June, led by Iraq, Saudi Arabia and Nigeria. It said Saudi Arabia had told it that it pumped 10.56 million bpd last month, up 231,000 bpd from May. — SG/Reuters
