Saudis to cave first because oil funds their social welfare programs. Saudi barrels already being turned aside. Russians supply mainly to Europe so less concerned about stranded barrels. Permian small players, wildcatters etc have started to shut in because price is below their cost to produce. The small will get extinguished while those larger have financial resources to tough out demand destruction caused by COVID-19. Ultimately OPEC & Russia will balance it out in thr $50 per barrel area but not until lots of permanent damage to many economies. After all, they have to wait another month or 2 in order to save face.
