The problem isn’t so much the supply of cheap oil, its the refining process that has reached a deadlock. No one acutally knows how much oil is left, but at the moment the refining industry is working flat-out. No one appears to be investing in new refineries or improved oil technology at the moment.
Which means that, no matter how much of it is left in the ground, until the oil can be processed into gas, aviation fuel etc…we will have a percieved ‘shortage’.
I know almost nothing about the stock market, but it would seem that refined oil products, as opposed to Crude, will go up due to limited supply. Just my 2 cents worth..
