The Economist Warns about the 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. Policymakers now seem to be talking the dollar down. Yet this is a dangerous game. Why would anybody want to invest in a currency that will almost certainly depreciate?

The dollar's loss of reserve-currency status would lead America's creditors to start cashing those cheques—and what an awful lot of cheques there are to cash. As that process gathered pace, the dollar could tumble further and further. American bond yields (long-term interest rates) would soar, quite likely causing a deep recession. Americans who favour a weak dollar should be careful what they wish for. Cutting the budget deficit looks cheap at the price.
