Greenback is not just America's currency. It's the world's!

Why the Dollar's Reign Is Near an End

Excerpts:

Consider this: When a South Korean wine wholesaler wants to import Chilean cabernet, the Korean importer buys U.S. dollars, not pesos, with which to pay the Chilean exporter. Indeed, the dollar is virtually the exclusive vehicle for foreign-exchange transactions between Chile and Korea, despite the fact that less than 20% of the merchandise trade of both countries is with the U.S.

Chile and Korea are hardly an anomaly: Fully 85% of foreign-exchange transactions world-wide are trades of other currencies for dollars. What's more, what is true of foreign-exchange transactions is true of other international business. The Organization of Petroleum Exporting Countries sets the price of oil in dollars. The dollar is the currency of denomination of half of all international debt securities. More than 60% of the foreign reserves of central banks and governments are in dollars.

The greenback, in other words, is not just America's currency. It's the world's.

...

The dollar is about to have real rivals in the international sphere for the first time in 50 years. There will soon be two viable alternatives, in the form of the euro and China's yuan.

...

Foreign investors—private and official alike—hold dollars not simply because they are liquid but because they are secure. The U.S. government has a history of honoring its obligations, and it has always had the fiscal capacity to do so.

But now, mainly as a result of the financial crisis, federal debt is approaching 75% of U.S. gross domestic product. Trillion-dollar deficits stretch as far as the eye can see. And as the burden of debt service grows heavier, questions will be asked about whether the U.S. intends to maintain the value of its debts or might resort to inflating them away. Foreign investors will be reluctant to put all their eggs in the dollar basket. At a minimum, the dollar will have to share its safe-haven status with other currencies.

Comment: A very good article on currency exchange. (Which I find to be a complicated subject).
