RE:RE:OPEC may cancel output increase if Biden meddles I believe there already is a crude delivery problem in the making . Not of all crudes for which there are still adequate supplies but of sweet (low sulphur content) crudes Due to the high cost of natural gas outside North America, the cost of desulphurizing sour crudes in order to meet low sulphur product specs (distillates and jet fuels } has risen dramatically. The production of sweet crudes has already topped out, extra Opec+ crude production will be sour.
As winter progresses and demand for distillates increases (also jet fuel) The lack of sweet crude supply will become increasingly apparent.
I believe that is the fundamental reason for the SPR releases. The question in my mind is what will they release sweet or sour crude?
