The Japanese yen, the Eurozone euro, and the British pound have appreciated 16%, 14%, and 9%, against the USD, respectively, since their 2010 lows. Some say that the “US wins” since the Fed’s quantitative easing (QE2) will drive export growth via a weaker dollar. (Note that the Fed has not actually announced QE2, this is all just speculation.)
I’m not suggesting that the stated Fed policy will be to drive down the dollar. What I do know, however, is that the United States production model is not structurally positioned to enjoy the economic panacea that is a persistent debasement of the dollar, neither in the near- nor medium- term.
The bottom chart illustrates the export share in overall economic GDP, as forecasted by the European Commission (you can download this data at the Eurostat website). Notice that the US share of exports, expected to be just 12.3% in 2010, is minuscule compared to the export markets in Europe. So what I gather from a chart like this is that the weak dollar will hurt Europe much more than it will “help” the United States.
We need domestic policy to support full employment and the expansion of our export sector that will eventually arise. See Marshall Auerback’s post this week at Credit Writedowns for a discussion on austerity, currency wars, and exchange rates.
