The buying price of cash refers to the price at which banks buy foreign currency cash and customers sell it. Example: You take $65,438+0,000 to the bank and then change it into RMB, which is the conversion ratio calculated according to the cash purchase price.

For example, spot purchase price: someone did not take $65,438+0,000 to the bank, but remitted $65,438+0,000 to your account. This $65,438+0,000 is not in cash, but recorded in your account. You change dollars into RMB in your account, which does not involve cash, but only two currencies in your account. At this time, it is calculated according to the spot purchase price.
