Overview of remittance: remittance means that the remitter delivers his own currency to the local bank, and the bank issues a payment power of attorney, which is sent to foreign branches or correspondent banks by airmail to handle foreign exchange payment business. Through telegraphic transfer, banks have the opportunity to use funds because it takes longer than telegraphic transfer, so the exchange rate of telegraphic transfer is lower than that of telegraphic transfer, and the difference is equivalent to Yu Xinhui's interest. In the import and export trade contract, if it is stipulated that the commercial bill should be paid at sight, the prepayment bank will send the commercial bill and various documents to foreign countries for collection by letter. After seeing the draft, the importer's bank will transfer the foreign exchange to the negotiating bank by mail transfer (air), which is the application of mail transfer in import and export settlement. Sometimes, in order to delay the payment of loans, importers often add bills and remit payment terms to domestic letters of credit. In this way, we can not only avoid the backlog of our own funds, but also pay after inspection in China to ensure the quality of imported goods. The remittance voucher is a remittance payment power of attorney, and its content is the same as that of the telegram power of attorney, except that the remittance bank did not add a password to the remittance power of attorney, but the person in charge signed it on behalf of it. When handling remittance, the remitting bank will issue a bank remittance power of attorney issued by the authorized signatory of the bank, and then send it to the remitting bank by letter, and the remitting bank will handle the remittance procedures accordingly. However, remittance is rarely used in actual business for the following reasons: (1) The United States refused to accept remittance power of attorney from the 1990s; (2) With the improvement of communication tools, most banks have been equipped with SWIFT, telex and other equipment, the local area network and remote network of banks have been widely used, the communication cost has been greatly reduced, and telegraphic transfer is no longer an expensive remittance method; (3) There are some shortcomings such as long collection period, weak security, inconvenient inquiry, etc. In recent years, it is rare for overseas correspondent banks to send money in this way, which is a settlement method in which remittance units entrust banks to send money to foreign payee. Remittance can be divided into two types according to the different transfer methods and transmission methods, which are chosen by the remitter himself. Remittance is a remittance settlement method in which the remitter applies to the bank and deposits a certain amount and handling fee, and the remitting bank sends the remittance power of attorney to the remitting bank and authorizes the remitting bank to remit a certain amount to the payee. Remittance exchange rate is the remittance method to inform the transfer payee of the bank where the payment is made by letter after the bank sells foreign exchange. Because the postal journey takes a long time, banks can use customers' funds during the postal journey, so the exchange rate of letter transfer is lower than that of wire transfer. T/T is a remittance method, that is, the remittance bank deposits a certain amount of money into the remittance bank, which sends it to the destination branch or correspondent bank (remittance bank) by telegram or telex, instructing the remittance bank to pay a certain amount of money to the payee. Of the two remittance settlement methods, the remittance fee is lower, but the speed is relatively slow, while the wire transfer has the advantage of high speed, but the sender has to bear a higher telex fee, so it is usually only applicable in an emergency or when the amount is large. In addition, in order to ensure the authenticity of the telegram, the remittance bank adds the password agreed by both parties to the telegram; Mail transfer does not need to be encrypted, just sign it. Settlement of foreign exchange has the characteristics of wide application, simple procedures, flexibility and convenience, and is a widely used settlement method at present. First, remittance settlement, whether remittance or wire transfer, has no limit on the starting point of the amount, and can be used regardless of the type of funds. Second, remittance settlement belongs to a settlement method in which the sender takes the initiative to pay in different places. It is very convenient for the transfer of funds, the clearing of old debts and the settlement of current accounts between superior and subordinate units in different places. Remittance before delivery is also widely used in transaction settlement. If the sales unit lacks understanding of the credit status of the purchasing unit, or the goods are in short supply, the purchasing unit can remit money first, and then deliver the goods after receiving the payment, so as to avoid non-payment. Of course, when the purchasing unit adopts the transaction mode of remittance first and then delivery, it should know the credit status and supply capacity of the sales unit in detail to avoid blindly remitting money and not receiving goods. If you don't know the information and supply capacity of the sales unit, you can remit the money to the purchasing place, open a temporary deposit account at the purchasing place, and send someone to supervise the payment. Third, the exchange settlement method is not only applicable to the transfer of funds between units, but also applicable to the payment of relevant funds by units to individuals in different places, such as retirement wages, medical expenses, various labor fees and remuneration. It is also applicable for individuals to pay related money to units in different places, such as mail-order goods, books and periodicals, etc. Fourth, remittance settlement procedures are simple and convenient for units or individuals to handle. Bill exchange rate refers to the exchange rate used to exchange various payment bills. According to the maturity of bills, bills are divided into spot bill exchange rate and forward bill exchange rate. The exchange rate of remittance is also lower than that of wire transfer.
