When OPEC and Russia shook on increasing crude oil production by a million barrels daily to stop the oil price climb that had begun getting uncomfortable for consumers from Asia to the United States, there was no sign of what was to come just two months later: slowing demand in Asia, ample supply, and a brewing price war between Saudi Arabia and Iran. 

Saudi Arabia, Iran’s arch-rival in the Middle East, has been a passionate supporter of President Trump’s intention to pull out of the nuclear deal with Iran and reimpose sanctions. This support is not simply on ideological or religious grounds, it also has a purely economic motive: the less Iran crude there is for sale, the more consumers will buy from Saudi Arabia. 

Iran, however, is not giving up so easily. It has more to lose, after all, with the harshest sanctions yet coming into effect in the coming months. The first shots in this war were already fired: Saudi Arabia cut its selling price for oil shipped to all its clients except the United States, S&P Global Platts in a recent analysis of OPEC. Iran did the same and has indicated that it is prepared to do a lot more if any other producer threatens its market share. In fact, statements from senior government and military officials suggest that Iran is ready to go all the way to closing off the Strait of Hormuz. 

While analysts argue whether Iran’s threats have any teeth, oil demand news from Asia is giving OPEC another cause for worry. Slowing economic growth is dampening oil demand growth and both the Chinese yuan and the Indian rupee are falling against the dollar as a result of the economic developments in both Asia and the United States, whose economy is growing so fast that some are beginning to worry that it will soon run out of steam. 

So, OPEC’s internal fractures are deepening and likely to deepen further because Saudi Arabia and Iran are highly unlikely to put down their arms, even if it means cutting prices to uncomfortably low levels. Saudi Arabia could boost its production. According to Platts, it has the biggest portion of OPEC’s combined spare capacity. Iran is not really in a position to do so, what with exports already falling and expected to fall further as the November 4 start of the sanctions approaches. Yet Iran has made clear that it will not stop exporting oil and China, for one, has made clear it will not stop buying it.
