The development process can quickly unravel when a herd of speculative investors steers into a country. Brazil boldly attempted to regulate such speculation in 2010 and 2011. Their efforts were a modest success, but developing countries can’t bear the full burden of regulating cross-border capital flows.

“Hot money” in the form of short-term debt, currency trading, stock market, real estate speculation, all stampeded into emerging market developing countries in 2010 and 2011. Low interest rates in the developed world and higher rates in emerging markets triggered such financial flows. The fact that developing countries were growing faster than crisis-plagued industrial nations played a role as well. Via the carry trade, investors borrow dollars and buy Brazilian real. Then they short the dollar and go long on the real. Depend on the leverage factor an investor can make, well, a killing.
