Acomplementary currency is acurrency ormedium of exchange that is not necessarily a national currency, but that is thought of as supplementing or complementing national currencies.[2]: 3 [3]: 2 Complementary currencies are usually notlegal tender and their use is based on agreement between the parties exchanging the currency. According to Jérôme Blanc of Laboratoire d'Économie de la Firme et des Institutions, complementary currencies aim to protect, stimulate or orientate the economy.[4]: 7 They may also be used to advance particular social, environmental, or political goals.[5]: 4
When speaking about complementary currencies, a number of overlapping and often interchangeable terms are in use:local or community currencies are complementary currencies used within a locality or other form of community (such as business-based or online communities); regional currencies are similar to local currencies, but are used within a larger geographical region; andsectoral currencies are complementary currencies used within a single economic sector, such as education or health care. Manyprivate currencies are complementary currencies issued by private businesses or organizations. Other terms includealternative currency, auxiliary currency, and microcurrency.Mutual credit is a form of alternative currency, and thus any form of lending that does not go through the banking system can be considered a form of alternative currency.Local Exchange Trading Systems are a special form ofbarter that trades points for items. One point stands for one worker-hour of work, and is thus atime-based currency.
Current complementary currencies have often been designed intentionally to address specific issues, for example to increase financial stability.[6] Most complementary currencies have multiple purposes and/or are intended to address multiple issues. They can be useful for communities that do not have access to financial capital, and for adjusting peoples' spending behavior.[7] The 2006 Annual Report of the Worldwide Database of Complementary Currency Systems presented a survey of 150 complementary currency systems in which 94 respondents said that "all reasons" were selected, among cooperation, micro/small/medium enterprise development, activating the local market, reducing the need for national currency, and community development.[8]
Aims may include:
Alternative currencies increase in activity if the local economy slows down, and decrease in activity if the local economy goes up.[9][dubious –discuss] They are most successful if the currency circulates within the users, in cycles or loops, as shown in an analysis of the use of Sardex by 1,477 entities in Sardinia in 2013 and 2014.[10]
According to professor Nikolaus Läufer's theory, the use of local currencies such asFreigeld can only increase economic activity temporarily. Lengthy use of a local currency will ultimately result in a decline in economic activity and lead to a destabilization of the economy. This is due to the increased circulation velocity of the money as the amount in circulation decreases (as currencies as Freigeld reduce in value rapidly).[11][clarification needed]
There are some complementary currencies that are regional or global, such as theCommunity Exchange System,WIR and Friendly Favors, Tibex in theLazio region in Italy or the proposed global currencyterra.[12]
Acommunity currency is a type of complementary currency that has the explicit aim to support and build more equal, connected and sustainable societies. A community currency is designed to be used by a specific group.[13]
