The European Currency Unit (₠ or ECU, French pronunciation: [eky]) was a basket of the currencies of the European Community member states, used as the unit of account of the European Community before being replaced by the euro on 1 January 1999, at parity. The ECU itself replaced the European Unit of Account, also at parity, on 13 March 1979. The European Exchange Rate Mechanism attempted to minimize fluctuations between member state currencies and   the ECU. The ECU was also used in some international financial   transactions, where its advantage was that securities denominated in   ECUs provided investors with the opportunity for foreign diversification   without reliance on the currency of a single country.
