Community Exchange System

CES "is a new money system that attempts to link diverse complementary currency systems into a global network that will one day challenge and, hopefully, replace the unhealthy global money system."



Thomas Greco, citing Tim Jenkin:

Tim Jenkin describes the development and operation of the Community Exchange System (CES) which he founded in 2002. Beginning as a single local credit clearing exchange, CES has evolved into a global network of more than 340 local exchanges distributed over 34 countries.

- “The CES web site is just a tool for managing exchange groups, for keeping accounts and for advertising. Each group administers itself and has its own rules and conditions of use. This keeps the overall system democratic and provides the basis for a multitude of separate but interacting local economies. Some groups base their unit of value on the national currency while others use time (e.g hours or minutes)… The long-term vision of CES is to democratise the entire network. ... The CES has been operating for nearly nine years now and, though it is still minuscule compared to the global financial system, has demonstrated that it is as versatile as the conventional money system, and indeed more efficient in many ways. It caters to fairly large volumes of trade, permits international trade, provides an extremely efficient means of tax collection through an optional transaction levy, handles multiple conversion rates seamlessly and clears accounts instantaneously.”

While the CES prototype needs some refinement, it provides an operational “proof of concept” for the creation of a locally controlled, yet globally useful system of exchange that transcends the dysfunctional interest-based, debt-money system that is driving the world to destruction. I fully agree with Tim’s conclusions that:

- “In the new era of declining energy and other natural resources, the global economy is inevitably going to have to contract. The debt-based money system looks increasingly unstable in the current low-growth environment and definitely cannot operate in a Steady State Economy or Degrowth environment. A new exchange system that operates something like CES will be needed. Such an exchange system simply reflects the economic situation, it does not drive it. When interest is removed as a factor in exchange, the growth imperative is removed along with the debt bondage that most of us live under. Extraction mechanisms such as speculation, derivatives, securitisation, hedging and other casino-like activities that allow a parasitic class to skim off the wealth of a society are also excluded. The decentralisation of control and lack of opportunities to hijack the exchange system for private gain will return the money power to ordinary people. No longer will those who currently control the financial system be the ones who decide where society puts it efforts and how it allocates its resources. The realisation that money is information and not real stuff is hugely liberating because it means that a local community can create its own exchange system and not be dependent on the dysfunctional global one that is driving humanity to the brink of disaster. This has all been made possible by our ability to share information on the internet. Local communities should jump at the opportunity to be able to define and control their own destinies instead of allowing financial institutions and governments to do it.” (
