The delivery date is the date when the currency should be delivered when buying or selling foreign exchange. Buyers of foreign exchange should deliver their own currency, and sellers of foreign exchange should deliver the sold foreign currency. The qualified delivery date must be the business day of the country where the currency is delivered. Even if both parties to the transaction are holidays, as long as the country issuing the delivery currency is a business day, it is still a qualified delivery day. Delivery date can be divided into: (1) cash delivery date, which usually refers to two business days after the trading day; (2) The delivery date of the futures exchange usually refers to the delivery date of the spot exchange plus the delivery date calculated by several months. If this delivery date is unqualified, it will be postponed. If it is postponed until next month, it is not a routine postponement, but the other way around. Example:1988165438+1October 27th (Sunday), and the cash delivery date is165438+1October 29th (Tuesday); The one-month settlement date is 65438+February 29th (Thursday); The two-month settlement date is198965438+1October 30th (Monday); The three-month settlement date is February 28th.
