Percent of foreign reserves: 2.2 percent
In the summer of 2015, the People’s Bank of China began sharing its gold purchasing activity on a monthly basis for the first time since 2009. In December, the renminbi joined the dollar, euro, yen and pound as one of the International Monetary Fund’s reserve currencies, an expected move that required the Asian country to beef up its gold holdings. (The precious metal represents only 2.2 percent of its foreign reserves, so it’s probably safe to expect more heavy buying going forward.) And in April, China, the world’s largest gold producer, introduced a new renminbi-denominated gold fix in its quest for greater pricing power.
