GLOBAL IMBALANCES AND DESTABILIZING SPECULATION 1 HEINER FLASSBECK 2 MASSIMILIANO LA MARCA 3 ABSTRACT Global imbalances have become a major source of systemic risk to the global economy. They can be amplified by short term speculation such as the currency “carry trade”, which may prevent the real exchange rate to perform its adjusting role. The paper examines past and recent patterns of destabilizing short term speculative flows that have led to financial fragility and real costs for a number of developed and emerging market economies. Domestic policies aimed at preventing speculation should be coupled with the reestablishment of a cooperative global monetary system. Keywords: foreign exchange speculation, interest rate parity, global imbalances, carry trade.
