Oil watchers are focused on the Organization of Petroleum Exporting Countries (OPEC) this week as it convenes for its end-of-year gathering. While the question regarding whether OPEC will make a small additional group cutback for 2020 or just roll over its current OPEC plus production pact with Russia and other key non-OPEC producers might be headline grabbing for a few days, the end result might turn out to be moot. The question next year might not be what the oil cartel intends to produce, but its worsening reduction in operational flexibility. Various OPEC national oil companies are finding new risks to their ability to manage how much oil leaves their shores.
