Fiat money refers to currency designated as legal tender through government regulation, possessing no inherent value but deriving its worth from public confidence and institutional support. Scholars such as Frank A. Fetter highlighted its dependence on governmental authority, arguing that paper money acquires value through its status as legal tender. Anna M. Fitch observed that all forms of money, even those made of metal, operate as fiat within legal systems.
Carl Schurz criticized the risks of its decline in value, while Andrew Dickson White examined historical attempts at inflationary monetary policies. These viewpoints emphasize fiat money’s dual character: a mechanism for economic governance influenced by legal directives and societal trust, illustrating the transition from systems tied to physical commodities to contemporary monetary structures.
