Now the commodity bubble is expected to implode, world oil prices will fall, while world economic growth will accelerate, Sharma says. This process will last about twenty years, and then usher in a new decade of expensive oil. “The mania for oil bore striking similarities to the dotcom mania of the late 1990s," Sharma says. "At the height of the dotcom bubble, tech stocks comprised 25 per cent of global markets. After the bust, commodity stocks – energy and materials – rose to replace tech stocks and, by the end of the last decade, accounted for 25 per cent of global markets too.”
The commodity mania gave rise to a new industry of investment funds that allow even ordinary people to trade in commodities. The total sum invested in commodity funds has more than doubled over the past five years to more than $400bn in 2011. (RIA Novosti)
