Is Euro Ready To Replace US Dollar As Reserve Currency?
When the 20th century began, the U.S. was already the world's biggest economy, but the British pound still accounted for nearly two-thirds of official foreign-exchange reserves held by the world's central banks. The dollar didn't become the dominant currency until after World War II. Even then, some commodities still traded in pounds: The London sugar market didn't jettison sterling for a dollar-denominated trading contract until around 1980. The history lesson here is that, while the reserve and trade currencies can and do change, it takes a significant re-architecture of the world economy and trade and significant amount of time for it to happen. Nearly two-thirds of the world's central-bank reserves remain denominated in dollars, according to data from the International Monetary Fund, despite widespread fears of a mass exodus from the currency. The euro accounts for about a quarter -- up from 18% when it was introduced in 1999, but less than its predecessor currencies' share in 1995. Because the U.S. is such a huge trading partner for so many countries, the reserve buildup isn't easily unwound.
According to the Wall Street Journal, the dollar is also deeply entrenched in world trade. Businesses lower their transaction costs by dealing in a common currency. More than 80% of exports from Indonesia, Thailand and Pakistan are invoiced in dollars, for instance, according to the latest figures available in research by the European Central Bank, although less than a quarter of their exports go to the U.S.
While many nations want to change at least part of their reserve holdings from US dollars to euros, they know if they sell a significant share of their dollar reserves, it would weaken the dollar's value. That would potentially hurt their own trade competitiveness, and push down the value of their remaining dollar reserves. If they keep the dollars, a buildup of unwanted assets would only mount.
"There is no alternative to the dollar as a trading currency in Asia," Andy Xie, a Hong Kong-based economist told the Wall Street Journal. "Eventually, the renminbi [yuan] will replace the dollar in Asia, perhaps in our lifetime. But it will take at least 30 to 40 years."
