On Public Discourse, Acton Research Director Samuel Gregg looks at fiat money and how today it “represents the end of a long process of development whereby governments have used their power of legal tender to use money to pursue various policy goals.”

This brief excursion into economic history hints at some of the deeper economic—not to mention moral—problems associated with fiat money. One is, as noted, the greater ease with which it permits governments to devalue currencies, thereby reducing the wealth of those with assets denominated in that currency. This surely constitutes an injustice to those individuals and businesses that have saved and behaved in a fiscally responsible manner while simultaneously letting the fiscally imprudent off the proverbial hook.

This underscores the second problem associated with fiat money: its facilitation of systemic moral hazard throughout entire economies. Moral hazard describes those situations whereby people are encouraged to take excessive risks because of the implied assurance that someone (usually the state) will bail them out if the enterprise or investment fails. From this standpoint, fiat money’s very existence arguably encourages the development of moral hazard throughout every sector of the economy. The high level of the U.S. federal government’s public deficit, for example, is at least partly premised on the unspoken supposition that the Fed (which is, after all, a government institution that operates within legal parameters set by Congress and whose members are nominated by the President) can simply print more money in paper or electronic form if creditors e worried that the U.S. government’s borrowings cannot be covered by anticipated taxation revenues, foreign borrowings, and its existing resources. This in turn encourages more people and governments to buy U.S. government debt in the form of bonds, which permits more deficit-spending, thereby encouraging a cycle of ever-spiraling public debt.
