摘要：The paper analyses the official use of international currencies as reserve currency(store of value) and anchor currency (unit of account). Examining the role as a reserve currencywe note that the US dollar is the main reserve currency even if it recorded a decline given thedecrease of the value of the US dollar reserve holdings and the gradual diversification of thecurrencies used. Since 2010, the euro's share decreased continuously may be due to theEurozone crisis and the euro's depreciation against the US dollar. Then we show that the USdollar dominates as an anchor currency, though it was temporary abandoned during crisis time,having more than a regional dimension. At the same time, the use of the euro in exchange ratearrangements appears mainly in the regions that have close links with the euro area. Over thelast few years, we have witnessed a gentle orientation towards a multimonetary world, especiallyregarding the use of the international currencies as reserve currency given the diversification ofthe currencies in which central banks understand to hold international reserves and theincreasing share of the nontraditional currencies in total foreign exchange reserves.
