The article examines how carry trade positions and commodity price shocks impact exchange rates, interest rates, and the economy. Carry trades are influenced by market risk and exchange rates, not just interest differentials. Commodity price shocks significantly affect inflation and economic fluctuations. The Fed's response to commodity price increases can lead to price stability but also economic downturns. The Balassa-Samuelson hypothesis, which links productivity to exchange rates, is not supported by the data. Instead, there is a strong negative relationship between tradable sector productivity and real exchange rates.
