The outlook for the global economy in 2012 is clear, but it isn’t pretty: recession in Europe, anemic growth at best in the United States, and a sharp slowdown in China and in most emerging-market economies.
……Adjustment of relative prices via currency movements is stalled, because surplus countries are resisting exchange-rate appreciation in favor of imposing recessionary deflation on deficit countries. The ensuing currency battles are being fought on several fronts: foreign-exchange intervention, quantitative easing, and capital controls on inflows. And, with global growth weakening further in 2012, those battles could escalate into trade wars.
