Commerce is the primary responsible on the inflow of foreign exchange, as his main objective is to generate foreign exchange earnings. The export promotion is the main weapon that nations have to generate foreign exchange entries, this way the country gets fresh funds in exchange for manufactured goods or raw materials that they generate.
The Latin American countries are nations that have comparative advantages and they use them to export their raw materials abroad. Based on this mechanism and exploiting the advantages that nature has provide them, provoke the inflow of foreign currencies, more precisely dollars.
In Argentina the exchange rate that was established after the departure of convertibility caused that exports increased and so the foreign exchange entry. The Banco Central, responsible for maintaining the exchange rate, intervene daily the foreign exchange market and purchase the excess of dollars for the price not to come down.
In Switzerland the inflow of currencies was regulated through two measures that were prevailing since 1978. The first prohibited to foreigners, the acquisition of Swiss titles and the second one, limited imports of notes from foreign banks to a value of 20,000 Swiss francs per quarter per person. The reality proved, with the relentless rise of the Swiss franc over the year 1978, that these measures were practically null, and only other resolutions, combined with the program announced on November 1 by President Carter, have allowed some stability of the Swiss franc over the dollar.
