The professor of São Paulo School of Economics (FGV/EESP), Samy Dana, presents, in his column Caro Dinheiro, for the Folha de São Paulo newspaper, an alternative barely known by Brazilians with planned expenses in foreign currency that need to protect themselves from exchange rate changes: the exchange rate mini contract, also called Dólar Mini (Mini Dollar).

According to Samy, this term refers to the size of the contract, since the mini trades lots of US$ 5,000 - equivalent to 10% of the standard contract of BM&FBovespa. The modality consists of dollar purchase and selling agreements with future terms and fixed prices. The investor chooses the term he/she wants and executes the operation according to his/her needs. The idea is that between the day of purchase and maturity, one has the financial flow that compensates the exchange rate changes, explains the professor.

The professor also says that dealers can monitor their investments through personal electronic platforms offered by brokers, whose operating costs are lower than the rates of fund management. This is a good alternative for those who are worried about the dollar increase because of long trips abroad, exchange programs and housing outside the country, for example, concluded Samy.
