The buying price of cash refers to the price at which banks buy foreign currency cash from customers.

These two prices are used when customers convert foreign currency cash and cash into RMB (settlement) respectively.

The selling price is the exchange rate at which a bank sells its quasi-currency. Refers to the price of foreign currency sold by banks to customers, which customers use when purchasing foreign exchange.

The benchmark price, also called the middle price, is set by the bank according to the trading situation of various currencies in the international financial market. In China, the SAFE will release the benchmark prices of some currencies, such as US dollars and euros, and other currencies will be calculated by the banks themselves. If you want to change RMB into euros, you should use the selling price.

The conversion price of BOC is used internally by BOC and has no influence on ordinary customers.
