The document, which limits the type of exchange transactions authorized for the sector, states that the entities covered must carry out the activity "in a partial manner, limited to the purchase of foreign currency from their clients".
The foreign currency acquired "must be used exclusively in the exercise of the activity developed by the acquiring entity", and "the sale of the foreign currency acquired is prohibited".
The regulation also requires that operators obtain formal authorization from the central bank to carry out exchange activities.
Exchange rates may be freely negotiated with clients, as long as they are published publicly, according to the notice.
Each transaction must be accompanied by a receipt with the client's identification, amount, currency, rate applied and date of the transaction, and operators are also required to send statistical data on transactions to the BNA on a monthly basis.
The new notice comes into effect immediately and revokes the previous one.
