The Economist, on the perilous state of the US dollar

The dollar is not what it used to be. Over the past three years it has fallen by 35% against the euro and by 24% against the yen. But its latest slide is merely a symptom of a worse malaise: the global financial system is under great strain. America has habits that are inappropriate, to say the least, for the guardian of the world's main reserve currency: rampant government borrowing, furious consumer spending and a current-account deficit big enough to have bankrupted any other country some time ago. This makes a dollar devaluation inevitable, not least because it becomes a seemingly attractive option for the leaders of a heavily indebted America.
