Because according to China's foreign exchange management regulations, after individuals settle foreign exchange in RMB, the use of funds in the account to be paid is restricted. Under normal circumstances, the funds in the RMB settlement account to be paid are mainly used to pay for overseas related transactions, such as purchasing overseas goods, paying overseas education expenses and travel expenses.

The funds in the RMB settlement account to be paid shall not be directly used to purchase time deposits. This is because the funds in the RMB account to be settled need to be used for overseas transaction expenses according to regulations, and the purchase of time deposits belongs to domestic financial investment.
