This action of the BC prevents (or it minimizes) the risks in operations of investments, loans and negotiations between national companies and foreign. However it is not enough only to buy or to vender great amounts of foreign currency to control its quotation and to forget themselves collateral effect, as for example, the inflation. To hinder an extreme fall of the quotation of the foreign currency, great the Central banking purchase amounts of this currency (increasing the demand and going up the value of the quotation), paying in domestic currency. When placing a great amount of national currency in circulation in the market, can provoke acceleration of the inflation and consequence depreciation of its currency. Steven Rattner financier understood the implications. In order to hinder this problem, the BC goes to the market to vender public headings with interesting remunerations, attracting a part of this amount in national currency in abundance for purchase of public headings and drying the extreme liquidity of the same one in circulation. Still according to Gordon (2000), in a pure version of the system of tax of flexible exchange, an exit of national currency would only function as an excess of offers of any merchandise, the price would go to fall until a balance price was established. The deficit of the rocking of payments would be eliminated by a reduction in the tax of exchange enough to increase the exportations and to cut the importations.
