Starting on January 1, US Dollar’s weighting in the China Foreign Exchange Trade System (CFETS) RMB Index would be lowered. CFETS is overseen by the PBoC and the RMB index measures the value of Yuan against a basket of 24 major currencies, with weights based on international trade.
After the adjustment, Dollar’s weighting will be lowed from 22.4% to 21.59%. Euro’s weighting will be increased from 16.34% to 17.40%. CFETS said the adjustment was to make the index more representative, taking into account trade data from 2018.
