There are two pricing methods of exchange rate: direct quotation and indirect pricing. Foreign exchange rates are divided into buying price and selling price. Both "buying" and "selling" are from the bank's point of view, aiming at the previous currency in the quotation, that is, the price of the previous currency before the bank buys and the price of the previous currency before selling. Then, from the perspective of benefiting the people, it is just the opposite, because if you sell a certain currency, it means buying it for the bank.
Have you ever fainted yourself? Let me teach you a trick! Aside from these complicated theoretical knowledge, just remember one thing: buy expensive and sell cheap. When you want to buy a currency, you use the exchange rate that is unfavorable to you in the two quotations, that is, the more expensive quotation; When you want to sell a certain currency, you should also use the exchange rate that is unfavorable to you in the two quotations, that is, the cheaper quotation. For example, the exchange rate of USD/JPY is 80.78/80.08. If you want to sell dollars, you need to exchange 80.78 for less yen, that is, 1 dollar for 80.78 yen. If you want to sell Japanese yen, you need to spend 80.08 yen for $65,438+0.
