The influential report “One market, one money,” issued in 1990 under the leadership of the former French Finance Minister Jacques Delors, called for the creation of a single currency, relying on the specious argument that the single market could not function well otherwise. More realistically, advocates of a single currency reasoned that it would cause people to identify as Europeans, and that the shift to a single European Central Bank would herald a shift of power away from national governments.
而这便是1992年《马斯特里赫特条约》的目的，欧盟便诞生于马约中。1990年，在前法国财政部长德洛尔的领导下，著名报告《一个市场，一种货币》（One market, one money）发布了。该报告呼吁创造一种单一货币，其立论基础似是而非：没有单一货币，单一市场就无法良好运行。其支持者所提出的更现实的理由包括这会激起人们对欧洲身份的认同感、成立单一欧洲央行可以作为各国政府移交权力的先声等。
