Hedge in the forward market
Banks would often provide their clients with guaranteed exchange rates for the future exchange of currencies (forward rates). These contracts specified a date, an amount to be exchanged, and a rate. Any bank fee would be built into the rate. By securing a forward rate for the date of a foreign-currency-denominated cash flow, a firm could eliminate any risk due to currency fluctuations. In this case, the anticipated future inflow of real from the sale to Novo could be converted at a rate that would be known today.
