European Monetary System
A system established in 1979 whereby most member states of the European Economic Community linked their currencies to each other in anticipation of monetary integration. The first stage of the EMS was the European currency unit, then the ERM I, and, finally, the introduction of the euro and the ERM II. The European Monetary System also called for greater extension of credit between European countries. Among the methods the EMS used included the relative synchronization of national interest rates.
