Looking at this chart makes one think that what goes up must come down. Is it possible that the super spike in oil prices has come to an end due to greater fuel efficient driven by CAFE standards and technological breakthroughs like horizontal drilling and fracking? Are we going to undergo a long period of moderate to sharply declining crude prices? Look at the Case-Shiller Home Price Indices during the same period. There is some correlation but crude went up a far greater percentage. Is this all emerging market demand and supply issues? Is there more speculation than meets the eye?
