Parties that don't pay the people they have to pay to get oil "allocation contracts" often never get a drop of oil. "Allocation Holders" are typically not title holders no matter how loudly they protest. To market real refined products in this world you have to have title to product.
Magiister Operis™ understands that an allocation holder may not own product but can indeed deliver the product. If that is the case…then the ball is in the allocation holder’s court to prove what makes their supplier real, ready, etc. before asking for the buyer to prove being real, ready, etc.
