European Exchange Rate Mechanism - Wikipedia, the free encyclopedia |
 | | Before the introduction of the Euro, exchange rates were based on the ECU, the European unit of account, whose value was determined as a weighted average of the participating currencies. |
 | | A grid (known as the Parity Grid) of bilateral rates was calculated on the basis of these central rates expressed in ECUs, and currency fluctuations had to be contained within a margin of 2.25% either side of the bilateral rates (with the exception of the Italian lira, which was allowed a margin of 6%). |
 | | On December 31, 1998, the ECU exchanges rates of the Eurozone countries were frozen and the value of the Euro, which then superseded the ECU on a 1:1 basis, was thus established. |
