Opec is expected to stick with its strategy of not cutting oil production when its ministers meet in Vienna on Friday, with the cartel split over who should take responsibility for reducing supply to support prices. Delegates and Opec ministers say it is highly likely they will either rollover its 30m-barrel-a-day output target or increase it to accommodate the readmittance of Indonesia to the group, even though prices have slumped close to six-year lows. However, Saudi Arabia, the group’s de facto leader and largest producer, has opened a dialogue about potential production cuts in the future. In recent weeks the kingdom has shifted its tone for the first time since letting prices plunge last year to pressure high-cost rivals. “The reasons for the strategic decision to not cut production last November are still in place,” said Jamie Webster, oil analyst at IHS Energy. “Despite Opec nations suffering a lot more pain than any of them expected, everything still holds.”
