Abstract
The International Monetary System' is an expression indicating all the rules elaborated by the countries to ensure, thanks to currency, a stabilization of the exchanges, and indicating the whole of the institutions charged to control and organize the monetary exchanges between the countries. An international monetary collaboration is necessary, because of the nature of the international trade, which constitutes a richness for the nations, but also a potential source of monetary imbalances. Most of the countries opened on the world have some deficits or surpluses which cause variations of currency on the foreign exchange market, the value of their currency expressed in other currencies not only changes according to the commercial results, but also according to the phenomena of speculation. The bad aspect of the absence of rules, making it possible to organize the trade on a stable basis of rate of exchanges was never as obvious as during the time of discord between the nations. Against this danger, and with the need for supporting the exchanges of goods and services, the countries sought, in relation to the development of the international trade, to create a system of international payments guaranteeing the safety of the transactions.
