Back in the summer of 2008, when crude seemed poised to take out $150, Goldman decided to declare the start of a commodity supercycle and boosted its oil price forecast to $200. Shortly thereafter crude cratered, plunging to the low double digits, and causing many to scratch their heads whether Goldman was merely taking advantage of the pre-Lehman panic to sell into the euphoria. The same questions, but inverted, will likely follow today’s just as seminal note, one which this time calls for the end of a supercycle, this time of iron, with “The end of the Iron Age.”
