Saudi Energy Minister Khaled al-Falih said on Tuesday that there was flexibility and options were open on an OPEC-led supply cut agreement. Mohammed Falih, who holds the rotating presidency of OPEC, said monitoring was underway on the compliance level but he was satisfied and focused on everyone working together. Speaking to Reuters on the sidelines of a major investment conference in the capital Riyadh, Falih said there was a determination to do whatever it takes to bring oil inventories down to the five-year average but that some work remained to be done.
