This situation is usually 70 to 90 of the deposit amount.

This is because when assessing the applicant's credit risk, the bank will consider the amount of the deposit provided by the applicant and the applicant's credit record, income status and other information. The deposit can be regarded as the applicant's guarantee for the credit card debt, so the bank will evaluate the applicant's credit risk based on the amount of the deposit and grant a corresponding credit limit.

At the same time, the bank will also consider factors such as the applicant's repayment ability and credit history to ensure that the applicant can repay on time.
