The U.S dollar is shrinking as a percentage of the world's currency supply, raising concerns that the greenback is about to see its long run as the world's premier denomination come to an end.
When compared to its peers, the dollar has drifted to a 15-year low, according to the International Monetary Fund, indicating that more countries are willing to use other currencies to do business.
While the American currency still reigns supreme -- it constitutes $3.72 trillion, or 62 percent, of the $6 trillion in allocated foreign exchange holdings by the world's central banks -- the Japanese yen, Swiss franc and what the IMF classifies as "other currencies" such as the Chinese yuan are gaining.
