The grumps over at The Economist say the dollar, and the U.S. economy, is in for a royal screwing if the budget deficit isn't hacked, and pronto. Excerpt:
If America keeps on spending and borrowing at its present pace, the dollar will eventually lose its mighty status in international finance. And that would hurt: the privilege of being able to print the world's reserve currency, a privilege which is now at risk, allows America to borrow cheaply, and thus to spend much more than it earns, on far better terms than are available to others. Imagine you could write cheques that were accepted as payment but never cashed. That is what it amounts to. If you had been granted that ability, you might take care to hang on to it. America is taking no such care, and may come to regret it. […]
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. […]
America's challenge is not just to reduce its current-account deficit to a level which foreigners are happy to finance by buying more dollar assets, but also to persuade existing foreign creditors to hang on to their vast stock of dollar assets, estimated at almost $11 trillion. A fall in the dollar sufficient to close the current-account deficit might destroy its safe-haven status. If the dollar falls by another 30%, as some predict, it would amount to the biggest default in history: not a conventional default on debt service, but default by stealth, wiping trillions off the value of foreigners' dollar assets.
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.
