Pá minussiden mente folk, at afskaffelse af de nationale valutaer til fordel for ecuen ville være risikabel (57%) og bekostelig for virksomhederne (55%), at det ville være for omstændeligt at omregne priser til ecu (47%), og at deres land ville miste en del af sin suverænitet (46% anså dette for "vigtigt", 44% ikke).
On the negative side, people thought replacing their national currencies by the ECU would be risky (57%); costly for business (55%); mental calculations would have to be made to convert prices into ECU (47%); and that their country would lose part of its sovereignty (46% "important" versus 44% "not important").
