The Denationalisation of Money is a 1976 book by Friedrich Hayek, in which the author advocated the establishment of competitively issued private moneys. In 1978 Hayek published a revised and enlarged edition entitled Denationalisation of Money: The Argument Refined, where he speculated that rather than entertaining an unmanageable number of currencies, markets would converge on one or only a limited number of monetary standards, on which institutions would base the issue of their notes.
