Domestic trade volume

The term domestic trade volume describes the sum of the value of all goods that are traded within a country or an economic area. A high volume of domestic trade strengthens a country's self-sufficiency , but weakens exports and thus the country's foreign exchange reserves. World wars and world economic crises lead to an increase in domestic trade . Since 1948, with few exceptions, the volume of domestic trade in the individual countries or economic areas has fallen in relation to the volume of world trade .
