The Commodity Roller Coaster

The details may change, but the global commodity super-cycle follows a familiar pattern. The question now is: Has the ongoing commodity-price downturn run its course, or will the recent break soon be giving way to another drop?

CAMBRIDGE – The global commodity super-cycle is hardly a new phenomenon. Though the details vary, primary commodity exporters tend to act out the same story, and economic outcomes tend to follow recognizable patterns. But the element of predictability in the path of the commodity-price cycle, like that in the course of a roller coaster, does not make its twists and turns any easier to stomach.
