Gulf nations including Saudi Arabia, Kuwait and the United Arab Emirates plan to oppose any cut to OPEC’s oil-production ceiling at next month’s meeting despite the continuing tumble in global oil prices, according to several people familiar with the situation. Members of the Organization of the Petroleum Exporting Countries have been reducing prices for weeks, often undercutting each other in a bid to boost or defend their market share. They’ve also signaled little willingness to cut output. But next month’s regularly scheduled OPEC meeting in Vienna offered an opportunity for the cartel to show a more unified voice and cut output to help support prices. Abdalla Salem el-Badri, OPEC’s secretary-general held out the possibility last month that the 12-nation group could agree to reduce the limit on its daily production by 500,000 to 29.5 million barrels a day when it gathers on Nov. 27. Continued opposition by Saudi Arabia, Kuwait and the U.A.E., however, now makes any cut highly unlikely. Gulf nations worry any reduction in the limit on OPEC production would lead to them losing share in global oil markets, the people familiar with the matter said, even if that means oil prices keep dropping.
