This is more than a diplomatic row among GCC members. Perhaps emboldened by President Trump’s visit, Saudi Arabia and its allies have declared if you are with Iran (or specific radical Sunni groups), you are against us. This effort to delineate sides in the region cannot be easily reversed without substantial outside pressure. Expect a geopolitical premium to creep into energy prices as this dispute continues.
Notwithstanding the pageantry of the U.S. President visiting Saudi Arabia and the enthusiasm of young Iranians hailing their moderate President’s reelection, little changed in terms of the region’s political stability, the battle with ISIS or oil policy this weekend. The clearest signal from the weekend was the public and forceful assertion that the U.S. has allied itself with the Saudis versus Iran, which can only have stoked the age-old rivalry. This should not impact OPEC dealings this week as Iran’s production is near a top, but it is likely to have repercussions down the road when (and if) Iran’s productive capacity rises.
