Prices cannot fall, unless supply exceeds demand.
You've never heard the term "price fixing?"
Who is fixing the price and how are they doing it?

Sure I have, but it's not possible to do that with a market as big, and with as many moving parts as the oil business. There are way too many large players involved, and some of them are even governments. Wars get started over stuff like this.
No, the price has fallen because of increased supply - nothing more. Now, you can call that 'price fixing' on the part of the players involved, and perhaps it is, just not in the common understanding of the term.
