This paper addresses the question of which role the currencies of the three
major economies in the world might play in global trade after European eco
nomic and monetary union. Based on historical data about trade flows and in
voicing practices as well as "G-3" economies' inflation records, it is argu
ed that, most likely, the U.S. dollar will maintain its dominant role in tr
ade denomination far quite an extended period of time after the European ch
angeover. From the data discussed, the euro will immediately take an the ro
le of the second most important trade vehicle currency, well in advance of
the Japanese yen. Due to network effects, the euro is likely to gradually e
xpand its share in global trade invoicing thereafter, primarily at the expe
nse of the dollar in Central and Eastern Europe, the Mediterranean, and, pe
rhaps, also in Asia. (C) 1998 Academic Press.
