Explain more of how OPEC is fucking itself? (Layman's terms of course!)
Well, historically, OPEC has openly price fixed total production to make it profitable for all of it's members. Some members have bigger bills for oil production than others. But because there was such a huge "gap" between the price of oil, and the price (And demand for*) of the "next best" energy source (Whatever it is), they could freely shift this supply to affect the price per barrel and get it into a "sweet zone" that they all compromised on (So they could all make an "acceptable" profit.)...They did this so they wouldn't have to compete on an actual open market (Which would be better for us as consumers, vs better for them.)
And this happened for decades, until this last decade. Recently, because of speculators, it's been difficult to foresee how supply will effect price. Oil speculation is very risky because of this, and so is tinkering with supply. ALSO, because of new technologies (Fracking/Green ect), there is a "soft" ceiling now where if that price goes up to high, demand will DROP, rather than prices increasing. If it stays up to high, those drops could become systemic (For example--investors might feel it's time to build networks of alternative fuel stations--because now their sure they can make money, because the price of oil stabilized above X point.)...And because of how speculation is working, this means changes in supply are....very risky.
OPEC has tried to drop the supply a few times recently, and Saudi Arabia has given them the finger and increased supply. Because it really wants to avoid that "shift" over to new sources of supply. Some other nations (As I understand it) are hurt by this, because they are less flexible in their production (So require a higher price to maintain that acceptable profit.)
*The ubiquity of oil use is also an important factor. Certain fuels are significantly cheaper, but only because there is far less demand, because of how infrastructure puts a big initial price on lots of other substances that oil does have, thanks to it's age of use. When discussing price, that "initial" infrastructure cost comes into play along with the cost for developing/producing the material itself. So like fuel X might cost 1/3 as much as oil to produce, but if you can't make plastic out of it, and there are no fueling stations for cars to use and not enough production facilities match demand if those things existed? Then those costs would need to be added to find the true market cost of using fuel X or Y. Unless the government foots the bill!
