As a senior central bank executive in Belgium, he was closely involved in the design and implementation of the mechanism that led to the European single currency (Euro). He was subsequently identified by Business Week as the world's top currency trader, while general manager of the most successful off-shore currency fund. He was a professional consultant for more than a dozen years to multi-national corporations on four continents; and moved to the other end of the spectrum by advising Japan and developing countries in Latin America on how to optimize hard currency earnings.

Lietaer also served as a professor of International Finance and president of the most comprehensive and cost-effective electronic payment system in the world. His book The Future of Money, and its sequel, The Mystery of Money, are the basis of an international television series now being planned.

"I propose," Lietaer says, "that we choose to develop money systems that will enable us to attain sustainability and community healing on a local and global scale. These objectives are in our grasp within less than one generation's time. Whether we materialize them or not will depend on our capacity to cooperate with each other to consciously reinvent our money.
