Settlement of foreign exchange means that the exporter sells the foreign exchange collected to the national foreign exchange bank at the bank quotation. The methods of foreign exchange settlement provided by Chinese banks are: (1) foreign exchange collection and settlement, also known as collection and payment. It refers to the settlement practice that the negotiating bank of the letter of credit sends the export documents of the export enterprise to the foreign paying bank for payment after examination. (2) Negotiation, also known as bill settlement. It means that the negotiating bank discounts the beneficiary's draft according to the terms of the letter of credit or buys the freight documents under the letter of credit at a certain discount, and deducts the interest from the negotiation date to the expected date of receipt of the bill from the par value, and the balance is converted into RMB according to the foreign exchange quotation on the negotiation date and distributed to the export enterprises. (3) Regular settlement of foreign exchange. It means that the negotiating bank determines a fixed settlement period in advance according to the time required to claim from the foreign paying bank, and agrees with the export enterprise that after the expiration of this period, regardless of whether it receives the payment from the foreign paying bank, it will actively convert the ticket amount into RMB and distribute it to the export enterprise.
