Privately issued money can benefit consumers in many ways, particularly in the areas of value stability and product variety. Decentralized currency production can benefit consumers by reducing inflation and increasing economic stability. Unlike a central bank, competing private banks must attract customers by providing innovative products, restricting the quantity of notes issued, and limiting the riskiness of their investing activities. Although the Federal Reserve currently has a de facto monopoly on the provision of currency in the United States, this was not always the case. Throughout most of U.S. history, private banks issued their own banknotes as currency. This practice continues today in a few countries and could be reinstituted in the United States with minimal changes to the banking system.
