Much of the debate over global rebalancing has focused on the U.S.-China trade imbalance. But that’s missing the bigger picture. With the growth of cross-border supply chains—a signature feature of Asia’s trade in recent decades—it would be misleading to focus on bilateral imbalances and exchange rates. Instead of specializing in producing certain types of final goods, Asian exporters increasingly have specialized in certain stages of production and become vertically integrated with each other. So, as Asia’s economies strive to rebalance their growth models, we need to understand better how the regional supply chain affects the way exchange rates and shifts in global demand work.
