Let's start in 2011. The world is in a three-speed recovery, with Europe at the bottom, the U.S. in the middle, and Asia growing between 6 and 10 percent. If you're an investment bank looking for high returns, where do you look? The fastest gains are in the hottest markets, and the hottest markets are in the developing world. In particular, commodities investments (gold, silver, platinum, rare earth metals, oil) have soaked up lots of excess global money supply and central banks have dropped their interest rates. Commodities-rich economies like Russia, Brazil and the rest of Latin America have been key beneficiaries.
