The international use of the euro by private operators can primarily occur within the framework of transactions or for investment and financing operations. At the beginning of the 90s one estimated that about 50% of the exports of goods and services was invoiced in dollars, one third in one of the currencies that participate in the euro and only 5% in yen.
Although the part of the euro area in world exports is greater than that of the US, the euro will only assert itself progressively as a payment currency in international transactions.
