Zones are dollar-centric groups controlled by the United States.
The dollar zone was formed during the Second World War and its members are mainly the United States and its territories.
The US Dollar zone was established in 1939. In the US dollar zone, countries maintain a fixed price ratio with the US dollar and use US dollars and gold as the preparation for issuing currencies and storing them in the United States.
Foreign trade shall be settled in US dollars and shall not be implemented.
The difference between the dollar zone, the Zone and the Franc Zone is that it has no legal recognition or fixed legal form and is a loose informal organization.
Since the Bretton Woods Conference in 1944 identified the US dollar as the most important international currency, a capitalist monetary system centered on the US dollar was formed, and the US dollar was recognized as the world’s main reserve currency and settlement tool. The new US dollar area basically replaced the original US dollar area.
