Chinese yuan set to replace dollar

In practice, China is trying to make its currency convertible and give it a role as a reserve currency. The first experiment is limited to transactions between Hong Kong and the neighboring provinces. It is also proposed that the yuan renminbi be used in 8 neighboring countries, including Russia. With these countries, agreements have already been signed for the settlement of contracts in the Chinese currency. Perhaps it is no coincidence that the news was released on Christmas Day, when Western markets are closed, reducing the impact on the dollar. In addition, the first weeks of January are usually fairly quiet. This means that although for now the trial is limited, China is preparing to establish full convertibility of its currency to all other currencies.

If, after a trial period, China makes its currency convertible, the consequence is that importing countries must have reserves of yuan renminbi. To get them, central banks around the world will have to divest themselves of U.S. assets and Treasury bonds.
