China as Number One: How about the Renminbi?

Using simulations projecting Chinese economic growth into the future, this paper first examines when China will overtake the USA to become the largest economy. Demographic changes that affect economic growth are taken into consideration in these projections. China is expected to become number one sometime in the mid‐2020s, unless its growth rate of gross domestic product per worker declines dramatically, à la the lost decade of Japan. Next, the paper examines whether China becoming the number one economy will mean its currency, the renminbi (RMB), will become the international key currency. According to the basket currency regressions during the period that Chinese currency was gradually appreciating against the US dollar from July 2005 to August 2008, it is shown that the RMB has already acquired a strong influence on the Asian currencies. This shows that the RMB is fast gaining the status of a regional anchor currency for a possible regional joint float. As the Chinese government proceeds with internationalization of its currency, the RMB is expected to gain in the ranking of other aspects of international currency, such as the store of value and the medium of exchange.
