U.S. dollar down? Just wait awhile

In economics and in financial data analysis, superlatives are generally avoided. (Certain financial news shows on cable TV are the exception, of course.) Specificity and moderation are the rules -- after all, we're talking about business and money.

Still, given the forces that have affected the currency markets in the early 21st century, one can safely say that there has never been a currency quite like the U.S. dollar.
