In July 2017, the National Financial Work Conference again proposed to steadily push forward the internationalization of RMB and achieve capital account convertibility. Therefore, using Thimann's global status indicators, the global status changes of 22 countries or regions currencies between 2006 and 2015 were calculated. The global position of the developed economies is 73.36%, which is down 5.62% compared with the 2006's. The top three global positions of currencies still belong to the United States, the Euro zone and the United Kingdom. The proportion of emerging economies in global status increases compared with the 2006's. Among them, the rise of RMB is the most significant, which is from 2.69% to 6.58%.The conclusion made by the Blundell-Bond's system GMM model shows that the increase of 1% of RMB global status will increase 0.43% of the cross-border holding of Chinese financial assets in consideration of the economic scale, bilateral exchange rate fluctuations, bilateral interest rate differences and prices.
