Only the Weak Survive

TOKYO – The risk of global currency and trade wars is rising, with most economies now engaged in competitive devaluations. All are playing a game that some must lose.

Today’s tensions are rooted in paralysis on global rebalancing. Over-spending countries – such as the United States and other “Anglo-Saxon” economies – that were over-leveraged and running current-account deficits now must save more and spend less on domestic demand. To maintain growth, they need a nominal and real depreciation of their currency to reduce their trade deficits. But over-saving countries – such as China, Japan, and Germany – that were running current-account surpluses are resisting their currencies’ nominal appreciation. A higher exchange rate would reduce their current-account surpluses, because they are unable or unwilling to reduce their savings and sustain growth through higher spending on domestic consumption.
