The US treasury might still have the gold somewhere, but creditors may already have a lien on it. I wouldn’t be surprised if the US has multiple liens on individual units oh gold at this point.
The house of cards will come down, but it will take a crisis to do it.
Creditors?
How much gold of any type is owned by the US population at large?
The reason I ask this is because if there is an international call for all Gold owned by non US countries to be returned to those said countries...and that gold is found missing, would not a desperate US government attempt to shake down the domestic populace for the gold (right down to wedding rings and heirloom jewelry)?
