The unity of the human race, as envisaged by Bahá’u’lláh, implies the establishment of a world commonwealth in which all nations, races, creeds and classes are closely and permanently united, and in which the autonomy of its state members and the personal freedom and initiative of the individuals that compose them are definitely and completely safeguarded. This commonwealth must, as far as we can visualize it, consist of a world legislature, whose members will, as the trustees of the whole of mankind, ultimately control the entire resources of all the component nations, and will enact such laws as shall be required to regulate the life, satisfy the needs and adjust the relationships of all races and peoples...A world script, a world literature, a uniform and universal system of currency, of weights and measures, will simplify and facilitate intercourse and understanding among the nations and races of mankind.

Shoghi Effendi, World Order of Bahá’u’lláh, p. 203

It would be difficult to exaggerate the psychological and social impact of the anticipated replacement of the jumble of existing monetary systems - for many, the ultimate fortress of nationalist pride - by a single world currency operating largely through electronic impulses.

The need to promote the adoption of a global currency as a vital element in the integration of the global economy is self-evident. Among other benefits, economists believe that a single currency will curb unproductive speculation and unpredictable market swings, promote a leveling of incomes and prices worldwide, and thereby result in significant savings. The possibility of savings will not lead to action unless there is an overwhelming body of evidence addressing the relevant concerns and doubts of skeptics, accompanied by a credible implementation plan. We propose the appointment of a Commission consisting of the most accomplished government leaders, academics and professionals to begin immediate exploration into the economic benefits and the political costs of a single currency and to hypothesize about an effective implementation approach.
