gold, Silver, Copper, etc... All went up also. You just don't notice those as much because you don't fill your tank every other day or so with those commodities.

These are temporary market blips (unless war breaks out and then the maket will be said to have predicted the future).

No conspiracy. Just a market at work.

(Also keep in mind that when the price goes up those who were short the market are losing money...Commodity markets are incredible in that for every $ gained by one trader, there is a $ lost by another... Its a zero sum game for everybody accept the producer and even the producers hedge their positions so as to limit their risk.)
