Manipulation is the right word. A lot of stakeholders just do the manipulation when they want to show they are still in control.

For this, selling oil isn't as easy as it looks. First storing oil is a very vital thing as it is highly flammable even in its raw form. It smells really bad when stored and also it is almost impossible to sell a few barrels of oil. You need to have in thousands of barrels before it can be marketable. The bad part about oil is that unlike Amazon that charges you delivery fee, you have to transport the oil to the buyer yourself.
