Kosovo and the euro
Before the establishment of UNMIK, Kosovo (as part of Serbia) was bound to Yugoslav monetary policy, and the Yugoslav dinar. However, war-time inflation and tensions with the Federal Republic of Yugoslavia had severely discredited the Yugoslav dinar. As a result, many preferred to use and hoard foreign currencies instead of relying on the dinar. The most frequently used foreign currency was the German mark, although the U.S. dollar and Swiss franc were also widely used.
