I believe these “shadow sales” are indeed taking place in fairly large numbers, and that some investigative work needs to be done.
There are many powerful interests who want to see the banks made solvent. It’s obvious that the massive interventions we’ve seen so far were intended to buy some extra time, not solve the problem. It would be perfectly logical if the govt/banks were working to off-load much of this inventory at a higher price — currently caused by the massive supply/demand distortions of the credits, low rates, withholding of inventory, etc.
