Do exchange rates drive the size of trade surpluses?
Core argument: Asia's trade surplus of $1.5 trillion is larger as a share of world GDP than at any point since 1945, and it is the only large surplus in the global economy.
At $1.5 trillion, Asia’s trade surplus is far larger as a share of world GDP than at any point since 1945. It is also the only large surplus in the global economy. Currency moves were central to the development of the trade imbalances that preceded the 2008 global financial crisis. From 2002 to 2005, for instance, the renminbi was tightly linked to a depreciating dollar even as Beijing’s entry to the World Trade Organization turbocharged Chinese exports. The resulting depreciation is a key reason why China’s surplus reached ten percent or so of its GDP—the first China shock. Conversely, the 40 percent real appreciation in the renminbi from 2005 to 2014 was a big reason why China’s surplus fell back to under two percent of its GDP. Exchange rates still matter, and they have a meaningful impact on the balance of trade.
