An article published in the Financial Times Wednesday discusses a forecast by GFMS, a consultancy, which believes that the world’s central banks will purchase 15 tonnes of gold on a net basis this year, the first net purchase since 1988, according to GFMS. Central banks for a number of years have been liquidating their gold stockpiles in favor of holding paper currencies such as the U.S. dollar.

Now, the tide may be turning, the article posits. If so, it would fit the idea that central banks wish to decrease their holdings of the U.S. dollar as a percentage of their so-called reserve assets, which totaled roughly $8.6 trillion at the end of August, according to data from the International Monetary Fund. China holds around $2.5 trillion of that total, mostly in U.S. dollars, which were built up from the very large trade surplus that China has with the United States.
