NEW YORK — Much of America's dominance in world finance comes from the dollar's status as international money. America's commitment to free capital markets, the rule of law, and price stability confer credibility on the dollar as a store of value. But American spending habits have undermined the dollar's reputation, with the excess supply of dollars on world markets depressing its price.

This spring, the euro's exchange rate against the dollar reached an all-time high, and central banks have increased the euro share of their international reserves. Is the dollar about to lose the crown of world finance to the euro?

History suggests otherwise, despite a vulnerable dollar.
