ICBC suddenly deducted my overdraft interest.

If you receive an interest deduction prompt, it is generally because the credit card you hold has overdraft cash withdrawal, overdraft transfer, urgent need of money, or failure to repay in full and on time, resulting in overdraft interest.

Interest is calculated until the amount payable is paid. If you have paid off, the interest will stop and will not continue to increase. Interest will not be deducted in advance, and the actual interest will be recorded on the bookkeeping date.

Credit card, also called debit card, is a credit certificate issued by a commercial bank or credit card company to eligible consumers. It is a card with name, expiration date, number and cardholder's name printed on the front, and a magnetic stripe and signature strip on the back. Consumers with credit cards can go to specialized commercial service departments for shopping or spending, and then the bank will settle accounts with merchants and cardholders, and cardholders can overdraw within the prescribed limits.

Credit card consumption is a non-cash transaction payment method, and there is no need to pay cash when spending, and repayment is made on the billing day.

Credit cards are divided into credit cards and quasi-credit cards. Credit card refers to a credit card in which the cardholder has a certain credit limit and can spend first and then repay. Quasi-credit card refers to a quasi-credit card in which the cardholder deposits a certain amount of reserve fund according to the regulations, and when the balance of the reserve fund account is insufficient to pay, it can be overdrawn within the prescribed credit limit. Credit cards generally refer to credit cards.

Credit card interest rules:

1. overdraft cash withdrawal transfer: interest-free repayment period is not enjoyed, and overdraft interest is paid at the rate of 0.5 ‰ per day from the bank bookkeeping date to the repayment date.

2. Consumption: the interest-free repayment period is from the bank bookkeeping date to the due repayment date (inclusive), and there is no overdraft interest for timely and full repayment. If repayment is made according to the minimum repayment amount, ICBC will charge overdraft interest at the rate of 0.5 ‰ per day from the bank bookkeeping date to the repayment date, and the overdraft interest will be compounded monthly.

Tips: partial product execution tolerance and full penalty interest: for overdraft transactions with interest-free repayment period (including the repaid part, except service fee), if the repayment amount in the current period is not fully paid off, overdraft interest will be paid from the bank bookkeeping date to the repayment date.
