Has Russia Just Pulled Itself Out Of The Petrodollar? The graph above shows a classic speculative bubble. The futures in the derivatives oil markets which is like the Chicago farm futures market, is prone to speculative bubbles. When these happen and consumer prices shoot upwards, we have an inevitable crash. All speculative bubbles pop. They have done this for the last 400 years. Each cycle of bubble/collapse leads to vain attempts at preventing bubbles that collapse after while. That is, people are burned by bubbles and then do it all over again once the memory of the pain fades. But if governments intervene to prevent speculator pain, they go merrily from one bubble to the next with no hesitation expecting to be bailed out over and over again, faster and faster.
