In economics, a local currency is a currency that can be spent in a particular geographical locality at participating organisations. A regional currency is a form of local currency encompassing a larger geographical area. A local currency acts as a complementary currency to a national currency, rather than replacing it,  and aims to encourage spending within a local community, especially with locally owned businesses. The currency may not be backed by a national government or be legal tender. About 300 complementary currencies, including local currencies, are listed in the Complementary Currency Resource Center worldwide database.
- Complementary currency - is used as a complement to a national currency, as a medium of exchange, which is usually not legal tender.:2
- Community currency - a complementary currency used by a group with a common bond, such as residents of a locality, association, or members of a business or online community.
- Local currency - a complementary currency used in a locality.
- Regional currency - a local currency where the locality is a larger region.
- Auxiliary currency, microcurrency, Eco-Money - less common synonyms for community or local currency. (see for example Douthwaite & Wagman 1999)
- Private currency - a currency issued by an individual, business or non-governmental organization. Complementary currencies are a type of private currency.
- Sectoral currency - a complementary currency used within one economic sector, such as education or health care.
- Alternative currency - generally, a synonym for complementary currency, referring to a currency designed to work in conjunction with the national currency; less often refers to a type of private currency which attempts to supplant or circumvent the national currency.
1. Local currencies with negative interest rate or demurrage tend to circulate much more rapidly than national currencies. The same amount of currency in circulation is employed more times and results in far greater overall economic activity. It produces greater benefit per unit. The higher velocity of money is a result of the negative interest rate which encourages people to spend the money more quickly.
2. Local currencies enable the community to more fully utilize its existing productive resources, especially unemployed labor, which has a catalytic effect on the rest of the local economy. They are based on the premise that the community is not fully utilizing its productive capacities, because of a lack of local purchasing power. The alternative currency is utilized to increase demand, resulting in a greater exploitation of productive resources. So long as the local economy is functioning at less than full capacity, the introduction of local currency need not be inflationary, even when it results in a significant increase in total money supply and total economic activity.
3. Since local currencies are only accepted within the community, their usage encourages the purchase of locally produced and locally-available goods and services. Thus, for any level of economic activity, more of the benefit accrues to the local community and less drains out to other parts of the country or the world. For instance, construction work undertaken with local currencies employs local labor and utilizes as far as possible local materials. The enhanced local effect becomes an incentive for the local population to accept and utilize the scrips.
4. Some forms of complementary currency can promote fuller utilization of resources over a much wider geographic area and help bridge the barriers imposed by distance. The Fureai kippu system in Japan issues credits in exchange for assistance to senior citizens. Family members living far from their parents can earn credits by offering assistance to the elderly in their local community. The credits can then be transferred to their parents and redeemed by them for local assistance. Airline frequent flyer miles are a form of complementary currency that promotes customer-loyalty in exchange for free travel. The airlines offer most of the coupons for seats on less heavily sold flights where some seats normally go empty, thus providing a benefit to customers at relatively low cost to the airline.
5. While most of these currencies are restricted to a small geographic area or a country, through the Internet electronic forms of complementary currency can be used to stimulate transactions on a global basis. In China, Tencent's QQ coins are a virtual form of currency that has gained wide circulation. QQ coins can be bought for Renminbi and used to buy virtual products and services such as ringtones and on-line video game time. They can also be obtained through on-line exchange for goods and services at about twice the Renminbi price, by which additional 'money' is being directly created. Though virtual currencies are not 'local' in the tradition sense, they do cater to the specific needs of a particular community, a virtual community. Once in circulation, they add to the total effective purchasing power of the on-line population as in the case of local currencies. The Chinese government has begun to tax the coins as they are exchanged from virtual currency to actual hard currency.
Difficulties and criticisms
Local currencies and the Transition Towns movement in the UK have been criticized for failing to address the needs of the wider population, especially lower socio-economic groups. Such local currency initiatives have been more widely criticized as having limited success in stimulating spending in local economies, and as an unrealistic strategy to reduce carbon emissions.
Modern local currencies
Modern local currencies can be classified into the following distinct types:
1. Transition currency based on the local currencies used by the Transition Towns movement in the UK. They include Brixton Pound and Bristol Pound in the UK, BerkShares in the USA, and Salt Spring Dollars in Canada.
Transition currencies are payment voucher-based systems that are exchangeable with the national currency. Between 2002-2014 many experiments in local currency took this form. Such currencies aim to raise the resilience of local economies by encouraging re-localisation of buying and food production. The drive for this change has arisen from a range of community-based initiatives and social movements. The Transition Towns movement originating in the UK has utilised local currencies for re-localisation in the face of energy descent from peak oil and climate change. Other drives include movements against Clone town and Big-box trends.
2. Rewards currency based on the frequent flyer model. Consumer spends cash with participating businesses who issue rewards points in a local currency. These rewards points can be used to offset cash prices in future purchases. An example is Oakland Grown in Oakland, CA.
3. Mutual Credit currency based on the mutual credit system. This can be further sub-divided into two:
a. Time-based currency also known as Time Banks that use time as a measure of value. An example is Dane County Time Bank.
b. Trade exchanges and LETS (local exchange trading system) that use price as a measure of value. An example of local currency implemented as a trade exchange is Bay Bucks in the Bay Area of California, USA. LETS were originally started in Vancouver, Canada, there are presently more than 30 LETS systems operating in Canada and over 400 in the United Kingdom. Australia, France, New Zealand, and Switzerland have similar systems.
