ICBC has no restrictions on the number or amount of transactions for investors to buy and sell crude oil in their personal accounts in RMB. Affected by regulatory policies, ICBC has set upper and lower limits on the total net transaction amount of all investors buying and selling crude oil in RMB.

Total net transaction refers to the difference between the total amount of crude oil bought by all investors in RMB accounts and the total amount of crude oil sold in RMB accounts. When the net amount reaches the set upper or lower limit, ICBC has the right to restrict all investors from opening new positions, and the liquidation of crude oil in existing accounts will not be affected.

The crude oil in ICBC's account is an investment transaction product provided by ICBC for individual customers. The crude oil share is traded in RMB or USD, and only the share is counted and the physical crude oil is not extracted.
