The joint agreement by OPEC and other oil-producing allies to raise output demonstrates the strength of the Saudi-Russian energy alliance, which will help stabilize the market for many years to come, the head of Russia’s sovereign wealth fund said on Monday. The Organization of the Petroleum Exporting Countries (OPEC) and other top crude producers agreed to raise output from July by about 1 million barrels per day (bpd). Ahead of OPEC’s Vienna meeting, Saudi Arabia and Russia, the world’s top oil producers, said they had a general consensus that the OPEC+ format should be “institutionalized” and extended until 2019 and beyond to monitor the market and change output if needed. “A long-term partnership between Russia and Saudi Arabia related to the coordination of efforts between oil producers and the future creation of a new organization based on OPEC+ will help overcome disagreements between the producers and work out a united action strategy on the global markets,” Kirill Dmitriev, the head of the Russian Direct Investment Fund (RDIF) told Reuters. Dmitriev said that long-term Russia-Saudi cooperation “will ensure pricing stability on global markets and increase investments in the energy sector.”
