Data on Currency Composition of Official Foreign Reserves (COFER) are now available in IMF eLibrary Data.
The data cover monetary authorities' claims on nonresidents denominated in U.S. dollars, euros, pounds sterling, Japanese yen, Swiss francs, and other currencies. Before the 1999 introduction of the euro, the European currencies identified separately were the ECU, Deutsche mark, French franc, and Netherlands guilder. COFER data for individual countries are strictly confidential. The data are disseminated in aggregate form for each currency for three groupings: World, Advanced economies, and Emerging and developing economies. At the present, 33 advanced economies and 105 emerging and developing economies report COFER data to the IMF.
Frequency and Updates
COFER data are reported and updated at quarterly frequency.
The definition of foreign exchange reserves and the classification of countries in COFER (as advanced economies or emerging and developing economies) follow those currently used in the IMF’s International Financial Statistics (IFS).
