Monetary system

From Wikipedia, the free encyclopedia

A monetary system secures the proper functioning of money by regulating economic agents, transaction types, and money supply.

Monetary systems are traditionally formed by the policy decisions of individual governments and administrated as a domestic economic issue. The current trend, however, is to use international trade and investment to alter the policy and legislation of individual governments. The best recent example of this policy is the European Union's creation of the euro as a common currency for many of its individual states. Another example is China's intentional devaulation of the Renminbi against other currencies.

Apart from monetary systems based on money, there do also exist systems based on "favours". One example of this is the LETS system. LETS, or Local Exchange Trading Systems, are local community trading groups where members exchange their goods and services with each other.
