China Construction Bank crude oil "monthly contract" is a contract method published by stages with reference to the month of the corresponding variety of the relevant crude oil exchange; All kinds of "account goods" of CCB will be released to customers in the form of contracts with reference to the practices of relevant exchanges. Under normal circumstances, each variety will provide two monthly contracts with different terms for customers to trade at the same time. When the contract transactions in recent months are closed, new contracts will be added in the order of regular time. At present, the tradable contracts are subject to the actual supply of China Construction Bank.

After the monthly contract of account goods expires, the processing methods include extension and automatic settlement. If the customer holds the contract until it expires and an automatic extension is set, CCB will close the contract in the near month and close the contract in the far month according to the customer's setting. If the customer holds the contract until it expires, and there is no automatic extension, then the Bank will close the customer's due position according to the settlement price of the corresponding variety in the international market on the expiration date.

CCB upgraded the account commodity business and added the real-time leveling function. At the same time, some products will be rescheduled according to market conditions. When the international commodity market price approaches zero or the reasonable expected price is negative, CCB will suspend all or part of the account commodity business transactions, and adjust the contract expiration processing time and processing rules.
